    In the field of petroleum extraction, deep well pump oil recovery equipment is the core equipment to realize the transportation of underground crude oil to the ground. Among them, the beam—type oil pump-oil pump device has become one of the most widely used types due to its high reliability and strong adaptability.

    During the operation of a pumping unit system, leakage is a common problem that affects production efficiency and equipment life. While "tubing leakage" and "pump leakage" are often mentioned, many people tend to confuse them. This article will systematically explain the differences between the two from four perspectives: definition, causes, impacts, and solutions, to help users quickly understand and diagnose the problem.

    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.

    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.

    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.”
