The value and application of insert rod pumps: As the core component of artificial lift systems, insert rod pumps have become increasingly strategically important during low oil price cycles: Insert rod pumps reduce costs and increase efficiency: their highly wear-resistant design and long-life structure significantly reduce maintenance and replacement costs. Insert rod pumps ensure productivity: they maintain stable lift in low-permeability, heavy oil, and deep well conditions, ensuring continuous well production. Insert rod pumps are highly adaptable: they can be customized to suit diverse reservoir conditions to meet diverse production needs. Insert rod pumps improve oil recovery: their stable and reliable lift efficiency helps oil companies maintain high production despite downward pressure on oil prices.

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.

On the oilfield floor, especially in shallow-to-medium formations, rod pumping has long been one of our engineering team's most commonly used, familiar, and reliable production methods. This isn't to say that other technologies are inferior—submersible electric pumps and progressive cavity pumps have their uses, but when it comes to cost-effectiveness, ease of maintenance, and versatility, rod pumping systems are the preferred choice. Why do we continue to use rod pumps? The reason is simple—not all wells are self-flowing, and not all wells warrant the expense of installing electric pumps. Especially when formation pressure is gradually decreasing, or when producing heavy oil, low-yield wells, or cyclic steam injection wells, we need a stable and easy-to-maintain mechanical recovery solution. In these situations, rod pumping is the preferred choice. Currently, there are two mainstream mechanical recovery methods: gas lift (mostly used in marginal water wells and light oil wells) and deep well pumping. Our rod pumping system is the most mature and widely applicable deep well pumping system. A complete sucker rod pump system consists of three main components: Surface unit (pump unit): Everyone is familiar with the "kowtow pump," the power source, consisting of a connecting rod and a reduction gearbox. Rod system: Connects the surface to the wellbore, transmitting power to the plunger. Downhole pump (sucker rod pump): The actual actuator, sucking up fluid and pumping it into the tubing.

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 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.

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.
