In order to ensure the processing accuracy and meet the requirements of the shape and position tolerance, it is necessary to avoid loading the card as many times as possible during the processing. It is a relatively heavy processing method of Deshi Machinery.

Dezhou United Petroleum Machinery Co., Ltd. (hereinafter referred to as “Deshi Machinery”) was established in 1970 and developed into a joint-stock company with a registered capital of 120 million. The company now has the most advanced product processing and testing equipment in the industry, and has obtained API, ISO9001, HSE and other system certifications, with more than 30 product patents. Deshi Machinery's products not only cover major oil fields in China, but also the network production designated enterprises of China Petroleum, Sinopec and CNOOC, and export to many countries and regions, enjoying high reputation in the international and domestic petroleum and petrochemical industries.

Deshi Machinery started with drilling mud pump Accessories, breaking the situation that the product has completely relied on imports since the 1980s, and became the first domestic enterprise to realize the localization of mud pump hydraulic end fittings, and gradually Started to manufacture whole products such as mud pumps. In 1987, Deshi Machinery began to develop screw drilling tools. After nearly 30 years of development, Deshi Machinery's screw drilling tools have been used? 43 to? The 286's high-speed, medium-speed, low-speed drilling tools are available, as well as high-temperature drilling tools for different temperatures, and can be designed according to customer needs to meet the requirements of personalized screw drilling tools. In addition, Deshi Machinery also produces a variety of downhole tools, non-magnetic products, wellhead facilities and oil production equipment.

Screw drilling tools are widely used in drilling, slanting and various workover operations in vertical and directional wells, side wells, horizontal wells, etc. in oil fields and coal mines, and can be used for composite drilling. The screw drilling tool is a volumetric downhole motor that uses high-pressure drilling fluid as a power tool to convert liquid pressure energy into mechanical energy. When the high-pressure drilling fluid pumped by the mud pump enters the screw drilling tool from the drill pipe, a liquid pressure difference is formed at the inlet and outlet of the motor, forcing the rotor to rotate, and the torque and the rotational speed are transmitted to the drill bit through the cardan shaft and the transmission shaft to realize the drilling operation. . The screw drilling tool looks simple and has a complicated structure. It consists of a bypass valve, a screw motor (rotor and stator), a universal joint shaft and a transmission shaft. The core part is a screw motor, which is also the key to improving the service life of the screw drilling tool. The importance of its processing accuracy can be seen.

Deshi Machinery attaches great importance to the machining accuracy and shape tolerance requirements of each component of the screw drilling tool. In the processing process, the processing technology of multiple processes is completed once, and the process concept not only can ensure the processing precision, but also reduce the processing strength of the operator. The company has all kinds of advanced processing and testing equipment. The special equipment of Deshi Machining Motor Rotor is the most advanced international equipment designed and manufactured by Europe. It is guaranteed from design, processing to inspection, with high processing efficiency and high precision. . Deshi Machinery also has machine tools for international brands such as Mazak in Japan, Doosan in Korea, and Demaghi in Germany. There are also a number of machine tools and machining centers produced by well-known domestic and Taiwanese machine tool companies, which ensure the machining accuracy of the accessories. . There are three indicators for measuring the performance of screw drilling tools: displacement, speed and torque. Providing high torque and high power screw drilling tools under the requirements of customer displacement and speed is the service target of Deshi Machinery.

The future development of Deshi Machinery needs more high-end equipment to ensure that domestic equipment needs to be improved in terms of processing quality and precision retention.
