Drilling site of "Long Page Flat 3 Wells”

On June 14, 2023, the cementing of the Changpaiping 3 well constructed by Songwon Runtong 50006 drilling team was successfully completed, marking the further improvement of the company's ability to drill key wells.Shale oil horizontal wells have difficulties such as poor wall stability, high frictional resistance and high torque, and shale debris is not easy to remove. Changpaiping 3 well is a key well deployed by the unconventional company of Jilin Oilfield, the construction party. The design depth is 4598 meters, and the horizontal section is 2000 meters long.After receiving the construction task, Songyuan Runtong Oil and Gas Exploration Service Co., Ltd., Great Wall Drilling and Drilling Company II, etc. overcame unfavorable factors and not only deployed elite soldiers as the backbone of the team's production, but also set up a technical expert group to formulate a detailed drilling operation plan.

During the construction, we arrange for technical personnel to stay in the well throughout the process, actively communicate technical details with the construction party, implement effective technical measures and operational records, and benchmark with the three Bohai Drilling and drilling companies for long-page flat 2 wells to make up for shortcomings, strengths and weaknesses, further improve the block construction plan, strengthen the whole process monitoring, and adjust drilling parameters in a timely manner to effectively overcome complex underground conditions such as stuck drilling and leakage.

At the same time, the 50006 drilling team conscientiously implemented equipment management inspections and post performance, and comprehensively investigated and corrected equipment hidden dangers; combined with the previous construction experience, the equipment maintenance and maintenance periods were rationally adjusted at different stages of the process.Based on well control safety and project quality, the team has a strong sense of red line, and strictly implements the abnormal information reporting system, which provides a strong guarantee for safe, high-quality and efficient well completion.
