1. Why do pumps frequently stick at the wellhead? In production of wells with high sand content, oil well pumps can experience plunger sticking and severe seal wear, impacting well production efficiency and equipment life. Conventional oil well pump designs have a short service life in sandy environments. To address this issue, we have developed a long plunger sand control pump. Below, we will provide a detailed analysis of the long plunger sand control pump.

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.

In this article, I will briefly introduce the main methods of oil extraction. Oil exists in layers of porous rock (accumulators). It is in these accumulators that the oil accumulates. A second prerequisite is that the accumulators must be covered by an impermeable oil and gas seal; otherwise, the gas will evaporate and the oil will eventually turn into bitumen. To extract oil, a well must be drilled. The well enters the oil-producing stratum, and here the fun begins—the oil must be brought to the surface somehow.

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 rod pump, also known as a rod pump, is a type of equipment used for oil pumping, which is mainly composed of a ground drive section, a downhole section, an electronic control section, and supporting tools. API rod pumps can effectively cope with high-viscosity, gas-bearing, and sand-containing crude oil during oil recovery, and are an important tool for modern oil well exploitation. Maintenance and servicing of API rod pumps are essential to ensure their efficient operation and extended service life. So do you know how to maintain and maintain rod pumps?

In the early stage of oil field exploitation, the oil reservoir often has a large amount of energy, and the oil can flow from underground to the ground by energy. As the energy of the oil reservoir is continuously consumed, when the energy of the oil reservoir is not enough to make the oil flow to the ground along the wellbore by its own energy, it is necessary to supplement the energy artificially to make the oil be extracted to the ground, which we collectively call artificial lift.

Composition of oil pump: The pump barrel assembly of API tubing pump is directly connected to the lower end of the oil pipe, and the plunger goes into the pump barrel with the sucker rod. API tubing pump consists of two parts: pump barrel assembly and plunger assembly. The pump consists of a pump barrel, a fixed valve and a hollow plunger with a floating valve. 2. Working principle: During the pumping process, the plunger reciprocates up and down in the pump barrel with the movement of the sucker rod. During the upstroke, the floating valve ball on the plunger is closed, the fixed valve ball is opened, and the plunger discharges the liquid in the upper chamber into the upper oil pipe of the pump. At the same time, the liquid in the well enters the lower chamber of the pump barrel through the fixed valve under the action of the inlet pressure. During the downstroke, the fixed valve is closed, the floating valve is opened, and the liquid in the lower chamber of the pump enters the upper chamber of the pump barrel through the inner cavity of the plunger. The plunger surges up and down, and the liquid is continuously pumped to the wellhead. 3. Analysis of the reasons for API tubing pump repair: For coalbed methane wells, repair is mainly caused by eccentric wear and pump failure. Well repair requires all the pipes to be lifted out of the ground. There is a detailed description later.

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.
