    Oil recovery by rod pump is realized by a rod pumping system based on “three pumping” equipment (pumping unit, pumping rod and oil pump). That is, under the drive of the pumping unit, the plunger of the pumping pump (also known as the deep well pump) is driven up and down by the pumping rod going down into the well, and the well fluid is drawn to the ground.

    Carbon fiber sucker rod centralizer uses carbon fiber and ultra-high molecular polyethylene, which have the advantages of light weight, high strength, high modulus, low density, high temperature resistance, corrosion resistance, etc. As raw materials. It is processed and molded by injection molding and other methods to effectively alleviate the frequent workover problems caused by well pipe wear and fracture. Its wear resistance is more than 5 times that of nylon centralizer.

    In the process of oil and gas exploration, a variety of machinery and equipment need to be used to ensure the smooth progress of exploration activities. These equipment cover many aspects from geological survey in the early stage of exploration to drilling, logging, well testing, and subsequent production operations. So today let's get to know these devices briefly:

    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.

    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.

    we will take a deeper look at more details of the movable barrel sand control oil well pump. 1. Detailed explanation of the working principle of the movable barrel sand control oil well pump: During the working process of the movable barrel sand control oil well pump, during the upstroke, the sucker rod will move the movable barrel sand control oil well pump upward, causing the oil outlet valve to close. As the space in the pump barrel cavity gradually increases, the pressure begins to drop. At this time, the liquid in the well will push the oil inlet valve open and smoothly enter the pump cavity. During the downstroke, the pump barrel moves downward, and the pressure in the pump increases accordingly. The oil outlet valve opens under the action of pressure, while the oil inlet valve closes. In this way, the liquid in the pump is smoothly discharged and flows into the oil pipe.

    Pumping unit is a ground-driven equipment with rod pumping. According to the basic structure of the oil pumping unit, the oil pumping unit can be divided into two categories: Free beam type and non-free beam type. The most widely used at home and abroad is the free beam type oil pumping unit (commonly known as kowtow machine). So today, let's take a closer look at the different types of beam-type pumps that can be used on rod pumps.

    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.

    The most commonly used deep well pump oil recovery device is a beam-type oil pump-oil pump device, which includes a pumping unit, the ground part of the wellhead device of the pumping well, and the underground part including the pumping rod, the oil pump, and the oil pipe. Among them, the pumping unit, the pumping rod, and the oil pump are the most important components of this kind of oil pumping device, the so-called “three pumping equipment.”
