Successful Promotion of the Rotary Steerable Drilling System in Daqing Oilfield

Recently, good news came from Well Shuang 66 - Ping 4, which was drilled by the Drilling Engineering Company. The rotary steerable drilling system independently developed by the Drilling Engineering Technology Research Institute completed a single - run drilling of 587 meters in the horizontal section of this well, marking a "good start" for the large - scale promotion and application of this technology.

The rotary steerable drilling system is a down - hole closed - loop automatic control system with functions such as power supply, measurement, steering, communication, and feedback. After 12 years of research and development, the Drilling Engineering Technology Research Institute has formulated a technical route of progressive development of functional modules, system integration, and function combination. It has also achieved an architecture that allows free combination and expandable upgrade among different modules, enabling the integration of logging - while - drilling (LWD) instruments with different functions.

It is understood that this achievement has been cumulatively applied in the full - horizontal - section construction of 5 horizontal wells, with a cumulative footage of 5,977 meters. The average mechanical penetration rate has increased by 129.49% compared with the sliding drilling with a screw - pump and LWD. The encounter rate of thin and poor - quality sandstone layers has reached an average of 86.4%, meeting the construction requirements for horizontal wells in thin and poor - quality layers. This year, Daqing Oilfield has arranged for the production of another 10 sets of rotary steerable drilling systems for large - scale promotion and application.

-------------In this solution, our company provided Daqing Drilling with downhole pulsers, generators, rectifier power supplies, steering head circuits, resolvers, hydraulic modules, etc.
