A sucker rod pump is a type of downhole equipment that, driven by a pumping unit, lifts crude oil from a wellbore to the surface. Commonly Used Sucker Rod Pump Categories Internationally: A tubing pump, also known as a tubing pump, is unique in that the outer barrel, sleeve, and suction valve are pre-assembled on the surface and connected to the lower portion of the tubing before being lowered into the wellbore. A piston equipped with a discharge valve is then fed into the pump via the sucker rod and tubing. Tubular pumps can be further divided into sleeve pumps and solid-barrel pumps.

Downhole sucker rod pump adopts an innovative double-layer pump barrel structure. Downhole sucker rod pump is designed for deep and thin oil well conditions. Downhole sucker rod pump is suitable for oil wells that cannot be produced normally due to insufficient formation fluid supply or low formation pressure in conventional lifting processes. The standard applicable well depth range is 2600 meters to 3500 meters.

How do pumpjacks actually bring crude oil from deep underground to the surface? Some might answer that it's the sucker rod pump. Indeed, the sucker rod pump plays a crucial role. However, a deeper look reveals that sucker rod pumps are divided into two types: rod-type sucker rod pumps and tubular-type sucker rod pumps. In our oilfields, rod-type sucker rod pumps are commonly used for oil recovery due to various practical considerations. Let's take a closer look at this crucial piece of equipment hidden deep underground—the rod pump—and learn about its working principles and functions.

Learn an in-depth understanding of efficient solutions to oil well degassing challenges. I. What is an anti-gas sucker rod pump? An anti-gas sucker rod pump is a type of pumping equipment specifically designed to address high gas content in well fluids. It is an improved version of the sucker rod pump. Its unique structural design and degassing mechanism effectively prevent gas from entering the pump body, resolving the "gas lock" or "gas cap" issues associated with conventional sucker rod pumps and improving oil recovery efficiency.

What are the advantages and disadvantages of the Sucker Rod Pump (SRP) system? That's what I'll share today. In the previous article, I introduced the fountain method and gas lift method for oil recovery. These two methods are typically used in the initial stages of oil field development, when internal energy or a small influx of external energy in the form of gas is sufficient to lift the oil.

Deep-well sucker rod pump is a mechanical oil production equipment used for deep well oil extraction, which is a core component of the rod pump oil production system. Anti gas sucker rod pump is a pumping equipment specifically designed for gas-bearing wells, mainly used to reduce or avoid the impact of gas on pumping efficiency. So do you know the difference between them?

There are many reasons for oil well pump inspections, which can be summarized into three categories: First, periodic inspections based on the pumping well's production patterns; second, production stoppages caused by sudden failures in the pumping well, primarily involving sucker rod pump failures; and third, pump replacements or deeper drilling to increase production. These inspections can be broken down into the following categories:

API sucker rod pump overview: 1. Structure of API sucker rod pump : API sucker rod pump is a sleeveless integral deep well pump, which is divided into two categories: top fixed type (RHA, RWA) and bottom fixed type (RHB, RWB); the structure consists of two major parts: plunger built-in pump barrel assembly and external fixed assembly. 2. Working principle: The working principle of API sucker rod pump is the same as that of tube pump, which relies on the reciprocating motion of the plunger to pump the well fluid to the ground. During the upstroke, the fixed valve and the annular valve are opened, the floating valve is closed, the well fluid washes the well pump barrel, and the liquid on the plunger is pumped to the ground; during the downstroke, the floating valve is opened, the fixed valve and the annular valve are closed to form a secondary compression, and the well fluid flows to the plunger through the floating valve. 3. Analysis of reasons for API sucker rod pump repair: The main feature of API sucker rod pump repair is that the pump can be brought to the ground for repair by pulling out the sucker rod instead of pulling out the oil pipe, which reduces the workload and intensity, shortens the recovery time of the lying well, and improves work efficiency. The main problems of API sucker rod pump are: the pull rod of the pump is easy to wear and break; after the coal powder is stuck in the pump, the pump plunger is directly unsealed when it is unstuck; the leather cup of the pump body falls off, causing the seal to fail; the pump fixed valve leaks. 4. Scope of use: API sucker rod pump is mainly suitable for vertical and inclined wells with small liquid production (well inclination <75°), wells with sand, coal powder and light scaling.

Our thermal recovery sucker rod pump is specially designed for the field of thermal recovery in oil fields and is designed to solve the problem of steam recovery in heavy oil extraction. Our thermal recovery sucker rod pump is produced in Tieling Dongsheng Petroleum Machinery Co., Ltd. , our annual supply capacity reaches 20,000 pieces, and we promise a standard delivery cycle of 8-10 weeks to meet the needs of global oilfield projects.

Ⅰ.The use of rod pumps to pump oil is the core method of oilfield mechanical oil recovery： In oilfield development, when the oil well cannot be self-injected due to insufficient formation energy, thick crude oil, etc., or the output is too low, it is necessary to use mechanical energy to recover oil. At present, the main mechanical oil recovery methods we use include gas lift oil recovery and deep well oil sucker rod pump oil recovery, and rod pump pumping is one of the important types of deep well oil sucker rod pump oil recovery. With the advantages of simple structure and easy maintenance, it is most widely used in oil fields around the world, especially in shallow and medium-sized oil wells.
