The air lock problem in heavy oil mining is being gradually solved by our company. We Tieling Dongsheng Petroleum Machinery Co., Ltd. with the design of this mechanical valve, the forced valve rod pump has achieved a breakthrough in reducing the air lock rate by 90% in oil fields such as Liaohe and Daqing. Today we will pass some key questions and answers to uncover the innovative core of this domestic technology.

Ⅰ. The structure of deep well oil sucker rod pump： Pumping rod pump is also called deep well rod pump. Our deep well oil sucker rod pump is a special equipment for mechanical oil recovery with rod pump.Under the pump, it is at a certain depth below the moving liquid level in the well shaft, and relies on the sucker rod to transmit the power of the sucker to extract the crude oil from the ground. Deep well oil sucker rod pump is divided into combined pumps and whole cylinder pumps according to whether there is a bushing or not. The working cylinder of the combined deep well oil sucker rod pump has several bushings, and it is pressed by the upper and lower compression joints; the working cylinder of the whole pump is a seamless steel pipe without a bushing inside. Deep well oil sucker rod pump is divided into two types: tubular pump and rod pump according to its installation method and structure in the well.

In the process of extracting oil, we will encounter some problems of aging or damage to equipment. At this time, we need to maintain and overhaul the equipment in a timely manner, and even replace the necessary parts and components. We all know that when mining oil fields, well workers sometimes can't see the underground environment so clearly. Petroleum may also have chemical effects on iron machinery. In the long run, it is inevitable that mechanical parts will rust, so at this time we need to replace the mechanical parts.

We Dongsheng Petroleum Machinery Co., Ltd.Launched a professional protection plan for the global transportation of brass pump barrels, through standardized packaging, environmental control and full process monitoring, in order to ensure zero damage to the brass pump barrels from the Liaoning factory to the international oilfield site.We have successfully applied this system to orders from more than 20 countries such as the United States and Canada, and the transportation loss rate has decreased significantly, which has become a key pillar to protect the interests of customers.

In the underground world of oil extraction, API standard sucker rod pump is like a tireless "underground miner", lifting crude oil from deep strata to the surface day and night. How does this seemingly mysterious equipment work? What "special skills" does it have to cope with different extraction environments? Today, we will unveil the technical veil of API standard sucker rod pump.

In the previous article, we mentioned the problems of sucker rod pump valve cover disconnection, pump failure, and valve leakage. Combined with the years of work experience of our technicians, we give specific suggestions. Let's take a look!

Application requirements of sucker rod pump: In the process of working of sucker rod pump, in order to ensure the long-term production capacity of oil fields, you can refer to the following contents: (1) the material strength of the suction valve and plunger of sucker rod pump must meet the actual use requirements, especially the pump barrel structure that bears the most pressure, which must have sufficient strength, hardness and sealing at the same time, and its overall shape will not deform when subjected to high pressure. (2) sucker rod pump needs to work underground for a long time, and in this extremely closed working environment, the equipment itself needs to have extremely high stability and reliability, and must have a long service life. (3) various valves and plungers need to meet the corresponding process requirements in terms of quality and material strength, and have high corrosion resistance, and pay attention to the impact of the working process of sucker rod pump on valves and plungers. (4) pay attention to daily maintenance procedures, and solve various problems faced by sucker rod pump in a preventive manner. Below, we will conduct a specific analysis of several common problems, hoping to help friends who encounter such problems. Let's read on!

Layered oil production: Background. In view of the current situation that the oil well joint production cannot meet the production needs due to the prominent contradiction between multiple layers and layers, the layer-stuck method is generally adopted for production. The main layer-stuck pipe string structure is as follows: Control layer-production layer. Production layer-control layer. Production layer-control layer-production layer. Through the application of various layer-stuck pipe strings, the problem of inter-layer interference is effectively solved, but the full play of the production capacity of each layer of the oil well is limited. At present, there is an urgent need for a layered co-production technology that can effectively mobilize each contributing oil layer and avoid inter-layer interference, fully tap the production capacity of the oil well, increase the production of the oil well, and improve the development time.
