Qinghai Oilfield Qaidam Hero Ridge has achieved high-yield industrial oil and gas flow

On June 26, the Hero Lingshixin 52-3 well in Qinghai Oilfield used 4 mm nozzle pressure control for production, with a daily oil production of 289.36 cubic meters and a daily gas production of 14,000 cubic meters, and won a high-yield industrial oil and gas flow.

Well Shixin 52-3 is located in the E32 reservoir in the southern belt of the western structure of Hero Ridge in the Qaidam Basin, and is a key development well deployed this year. The well was drilled to a depth of 4,750 meters on October 1, 2020, and was drilled through the target layer on May 23, 2021. During the drilling process, Qinghai Oilfield adheres to the integration of geology and engineering, applies fine pressure-controlled drilling, reduces the risk of leakage conversion, ensures the efficient and successful drilling of Well Shixin 52-3, and creates the best indicators of the average mechanical ROP of 6.29 m/h and the monthly speed of the drilling rig of 937 m/unit in this block, forming a supporting drilling and completion technology system, and laying an engineering and technical foundation for the next large-scale development.

The high-yield industrial oil and gas flow obtained from Well Shixin 52-3 further indicates that the Yingxi block has a rich resource base and development potential, and confirms the development potential of the E32 reservoir in the southern belt of the Yingyingling structure. In the next step, Qinghai Oilfield will explore the production dynamics of oil wells under different production systems according to the characteristics of reservoirs in the southern zone of the Yingxi structure and the production of wells that have been put into operation in the early stage to ensure continuous and stable production. We should further strengthen the processing of three-dimensional seismic data, delineate the structure, deepen the research on reservoir formation, and systematically evaluate and understand the characteristics of reservoirs, effective reservoir distribution characteristics and oil and gas distribution in the southwest of England, so as to lay the foundation for reservoir development and deployment and ensure efficient construction and production.
