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.

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：

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.

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.”

1. Control tools: Downhole tool control tools have undergone a transformation from simple mechanical devices to highly intelligent and automated equipment. Traditional downhole control tools rely on mechanical principles, have single functions and low efficiency. With the advancement of science and technology, modern downhole control tools have incorporated advanced technologies such as high-precision sensors, remote control systems, and data analysis software, which have significantly improved operating efficiency and accuracy.
