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.

Ⅰ. The structure of deep well oil sucker rod pump： Pumping rod pump is also called deep well rod pump. Our deep well oil sucker rod pump is a special equipment for mechanical oil recovery with rod pump.Under the pump, it is at a certain depth below the moving liquid level in the well shaft, and relies on the sucker rod to transmit the power of the sucker to extract the crude oil from the ground. Deep well oil sucker rod pump is divided into combined pumps and whole cylinder pumps according to whether there is a bushing or not. The working cylinder of the combined deep well oil sucker rod pump has several bushings, and it is pressed by the upper and lower compression joints; the working cylinder of the whole pump is a seamless steel pipe without a bushing inside. Deep well oil sucker rod pump is divided into two types: tubular pump and rod pump according to its installation method and structure in the well.

In the underground world of oil extraction, API standard sucker rod pump is like a tireless "underground miner", lifting crude oil from deep strata to the surface day and night. How does this seemingly mysterious equipment work? What "special skills" does it have to cope with different extraction environments? Today, we will unveil the technical veil of API standard sucker rod pump.

In the previous article, we mentioned the problems of sucker rod pump valve cover disconnection, pump failure, and valve leakage. Combined with the years of work experience of our technicians, we give specific suggestions. Let's take a look!

Application requirements of sucker rod pump: In the process of working of sucker rod pump, in order to ensure the long-term production capacity of oil fields, you can refer to the following contents: (1) the material strength of the suction valve and plunger of sucker rod pump must meet the actual use requirements, especially the pump barrel structure that bears the most pressure, which must have sufficient strength, hardness and sealing at the same time, and its overall shape will not deform when subjected to high pressure. (2) sucker rod pump needs to work underground for a long time, and in this extremely closed working environment, the equipment itself needs to have extremely high stability and reliability, and must have a long service life. (3) various valves and plungers need to meet the corresponding process requirements in terms of quality and material strength, and have high corrosion resistance, and pay attention to the impact of the working process of sucker rod pump on valves and plungers. (4) pay attention to daily maintenance procedures, and solve various problems faced by sucker rod pump in a preventive manner. Below, we will conduct a specific analysis of several common problems, hoping to help friends who encounter such problems. Let's read on!
