Elephant Machinery injection pump is generally applicable to oil extraction, particularly in fields such as enhanced oil recovery (EOR) and chemical injection. The primary types of Elephant Machinery injection pump include water injection pump, polymer injection pump, and CO₂  injection pump. Although they are all referred to as “injection pumps,” their design principles, operating mechanisms, and application scenarios differ significantly.   1. Water Injection Pump: Its core function is to inject water, wastewater, oilfield waste oil, and brine into oil reservoirs, increasing formation pressure to drive crude oil toward the wellbore. In practical applications, water injection pumps are widely deployed in various oilfield injection stations, to be critical equipment for achieving stable production and enhanced oil recovery. They are particularly suitable for developing medium-to-low permeability reservoirs. Through continuous and stable water injection operations, they improve waterflood efficiency in reservoirs and enhance crude oil extraction rates.       2. Polymer Injection Pump: To be a pump specifically designed for oilfield polymer flooding processes. Its core function is to inject polymer solutions, alkaline solutions, deactivators, binary fluids, or ternary fluids into reservoirs at precise flow rates and pressures. Through the adsorption, retention, and viscosity-increasing effects of polymer molecules within the pore medium, it effectively improves the water-oil mobility ratio, enhances the sweep efficiency, and increases oil recovery rates. In practical applications, polymer injection pumps demand exceptionally high flow stability and pressure control precision. Typically integrated into polymer injection stations for tertiary oil recovery operations, they are well-suited for developing mature fields with high water cut. By injecting high-molecular-weight, low-hydrolysis-degree polymer solutions, these pumps significantly enhance oil displacement efficiency and extend the operational lifespan of oilfields.       3. CO₂ Injection Pump: Its core function is to continuously inject supercritical or liquid CO₂ into oil reservoirs at specific pressures and flow rates. By leveraging the physicochemical interactions between CO₂ and crude oil—such as reducing crude viscosity, improving fluidity, expanding oil volume, and extracting light components—it enhances oil recovery rates. During process execution, CO₂ collected from emissions in energy production or other industries is sometimes utilized. In practical applications, this pump is widely employed in CO₂ enhanced oil recovery (EOR) technology, particularly suited for developing low-permeability, high-viscosity crude reservoirs. By injecting CO₂ into formations, it not only effectively improves crude fluidity but also enables geological sequestration of CO₂, achieving a win-win outcome of energy conservation, emission reduction, and resource development. It is to be a crucial piece of equipment for realizing green and efficient oilfield development.       The specific selection depends on the characteristics of the application scenario. For high-viscosity crude oil extraction requiring environmental benefits, CO₂ injection pumps are ideal, as they improve crude oil flow through physicochemical effects while sequestering CO₂. For medium-to-low permeability reservoirs, water injection pumps stabilize formation pressure to drive crude oil flow. For tertiary recovery operations in mature fields with high water cut, where enhancing sweep efficiency and oil displacement is crucial, polymer injection pumps with high precision control over flow rate and pressure are more suitable. Ultimately, the selection should be based on your application objectives, reservoir characteristics, and target recovery goals. Elephant Machinery can tailor customized solutions to meet your specific requirements.

Reciprocating pump is fluid transfer device that directly supply energy to liquid in the form of pressure energy through the reciprocating motion of pistons/plungers within cylinders. They are the most widely used positive displacement pumps in industrial applications, such as mud pump, pressure test pump, high pressure pump, cementing pump, and injection pump. Whether in oilfield water injection, high pressure cleaning, or drilling platforms, they play an extremely important role and hold an irreplaceable position. But have you ever wondered how a simple reciprocating motion generates stable pressure energy to drive fluid conveyance? Below, we'll introduce the most fundamental reciprocating motion, gradually guiding you toward a thorough understanding of the reciprocating pump's operating principle.   Core Components of Reciprocating Pump 1. Power end: Crankshaft, connecting rod, crosshead, intermediate rod, etc.; 2. Hydraulic end: Piston/plunger, piston seal/plunger seal, shock-resistant pressure gauge, safety valve, etc.; 3. Control valves: Suction valve, discharge valve (typically check valves); 4. Others: Lubrication system, cooling system, etc. Working Principle of Reciprocating Pumps The electric motor drives the pump's crankshaft to rotate via a large and small pulley and a narrow belt. The crankshaft drives the connecting rod, piston or plunger to perform reciprocating motion. When the piston or plunger moves backward, the inlet valve opens, allowing liquid to enter the pump body until the piston or plunger reaches its final position (crankshaft rotates 180°), concluding the suction process. The piston or plunger then begins its forward stroke. During this phase, the liquid within the pump's valve chamber is compressed, increasing pressure. Consequently, the inlet valve closes while the outlet valve opens, allowing the liquid to be expelled through the outlet valve by the piston or plunger. Materials of Reciprocating Pumps 1. Power-end components are predominantly castings, primarily made of materials such as QT450 and QT600. 2. Hydraulic-end components are flow-through parts requiring selection based on customer-provided parameters: Medium characteristics: medium name, specific gravity, viscosity, corrosiveness, toxicity, etc. lParticle diameter and content of solids in the medium. lMedium temperature: (°C) lRequired flow rate lPressure: suction tank pressure, discharge tank pressure. 3. Commonly used materials include but are not limited to the following: 45#, 304, 316L, 2205, 17-4PH, 0Cr17Ni2. Reciprocating Pump Working Cycle 1. Suction Stroke lDuring the suction stroke, the piston or plunger moves backward, creating a low-pressure zone within the cylinder. lThe inlet valve opens due to external fluid pressure, drawing liquid into the pump body. lAs the crankshaft continues to rotate, the piston or plunger gradually moves to its final position, completing the entire suction process. The key to this stage lies in ensuring the sealing integrity of the inlet valve to prevent air ingress or liquid backflow, thereby guaranteeing the pump's operational efficiency and stability. 2. Discharge Stroke lWhen the piston or plunger begins to move forward, the fluid inside the cylinder is compressed, causing the pressure to rise rapidly. lThe inlet valve closes, and the outlet valve opens under pressure. Liquid is expelled from the pump body through the outlet valve and enters the delivery pipeline. This process requires the drain valve to possess excellent pressure resistance and rapid response capabilities to accommodate frequent opening and closing demands under high pressure conditions. Efficient operation throughout the entire working cycle relies on the precise coordination between all components, thereby ensuring continuous and stable fluid delivery. Advantages of Reciprocating Pumps 1. Compatible with virtually any fluid; 2. High efficiency, exceeding 90%; 3. Adaptable to diverse operating conditions; 4. Extended service life; 5. Simple structure for easy maintenance and servicing; Flow Rate and Pressure of Reciprocating Pumps 1. Flow rate is determined by the piston or plunger, stroke length, and rotational speed. 2. Pressure is determined by the pump's power, valve sealing integrity, and discharge resistance. Reciprocating pumps are a type of positive displacement pump, to be, that achieves fluid conveyance through periodic changes in the volume of its working chamber. The mechanical energy from the prime mover is directly converted by the pump into pressure energy for the conveyed fluid. The pump's flow rate depends solely on the change in working chamber volume and the frequency of this change per unit time, and is (theoretically) independent of the discharge pressure.

CO2 injection pump is key to enhancing oil recovery. Injecting carbon dioxide into oil reservoirs effectively reduces crude oil viscosity, thereby accelerating crude oil movement and improving oil recovery rates.   1. Enhancing Pump Performance First, improving the pump body material can enhance its corrosion resistance and durability, thereby extending the equipment's service life. Second, optimizing the pump's structural design reduces energy loss and improves operational efficiency. Elephant Machinery offers clients intelligent pump station system design featuring unmanned operation capabilities and multi-terminal remote monitoring. This system enables synchronized control of reciprocating pump systems via computer and mobile clients with real-time data synchronization. These measures not only significantly boost pump efficiency but also reduce maintenance costs, providing more reliable support for overall oil extraction operations.   2. Reliability and Stability To achieve the reliability and stability of CO2 injection pump, the equipment must deliver higher and more consistent output pressure—a prerequisite to be enhanced oil recovery rates. Ensuring uninterrupted injection operations and preventing equipment-related shutdowns requires state-of-the-art sealing technology to prevent CO2 leakage, alongside cooling systems to manage heat generated during prolonged operation. When addressing complex geological conditions, pump design must also prioritize flexibility to rapidly adjust operating modes based on actual requirements, thereby better adapting to diverse reservoir development demands. Elephant Machinery employs internationally advanced production techniques to manufacture compact, space-saving, and lightweight products for your use.   3. Precise Flow Control Precise flow control plays a crucial role in the operation of CO2 injection pumps. By accurately determining the CO2 injection volume, we ensure the stability of the injection process. This allows for precise injection, improves the reservoir displacement front, increases the sweep radius, and reduces gas inrush.       4. Reduce Crude Oil Viscosity Crude oil's high viscosity makes it difficult to flow from the ground. When a CO2 injection pump is used, the CO2 dissolves in the crude oil, causing it to expand and reduce its viscosity, making it easier to pump the oil to the production well.   5. Replenishing Subsurface Energy As crude oil is continuously extracted, subsurface pressure gradually decreases. Injecting CO2 serves as an underground energy source to restore reservoir pressure. Compared to traditional water or gas injection, CO2 injection delivers superior results while also protecting the environment.     In summary, injecting CO2 into oil reservoirs not only effectively restores formation pressure but also enhances reservoir mobility, thereby improving crude oil recovery efficiency. This approach offers greater environmental sustainability compared to traditional methods while better accommodating complex geological conditions. Elephant Machinery has established valuable partnerships with national oil and pipeline companies such as SPC, KPC, and BAPCO, as well as numerous distributors who utilize our reciprocating pumps in oilfields across the Middle East, Russia, Africa, and South America. Concurrently, we are collaborating with South America's leading oil enterprise, SERTECPET, to develop unmanned water injection pump skids for oilfields.

The adoption of these innovative devices signifies that the oil industry is moving toward environmental protection and sustainability.   1. Enhancing Recovery Rates and Reducing Resource Waste In conventional oil extraction processes, only a portion of the oil is typically recovered, with the majority remaining trapped underground. The introduction of polymer injection pumps addresses this by enhancing oil mobility, thereby significantly boosting recovery rates. This approach not only minimizes resource wastage but also extends the operational lifespan of oil wells, ultimately improving the overall recovery performance of the petroleum industry. Furthermore, utilizing polymer injection pumps for oil recovery reduces adverse environmental impacts while demonstrating the integration of modern technology with environmental stewardship.     2.

Ensuring reliability and continuity not only reduces the risk of operational failures but also enhances work efficiency. By optimizing internal structures and utilizing high-quality materials, this equipment maximizes energy efficiency while minimizing energy loss, providing robust technical support for sustainable oil extraction.   3. Reducing Environmental Pollution The application of polymer injection pumps has significantly reduced environmental pollution caused by oil extraction. During pump operations, technicians can precisely control the injection volume of chemicals, thereby minimizing damage to groundwater and soil. Additionally, the equipment's reduced carbon emissions during operation further contributes to environmental protection.     4. Precise Control, Optimized Operations Polymer injection pumps utilize advanced technologies to achieve precise control over various parameters during petroleum extraction. This precision extends beyond regulating chemical injection volumes to encompass critical indicators such as pressure and flow rate. Employing this method for oil extraction prolongs the productive lifespan of oilfields, delivering sustained economic benefits.
