Core Viewpoint - Sinopec's Southwest Petroleum Engineering Company has successfully completed the drilling of the Yuanlu 35HF well, setting nine records in the Sichuan Basin, including the shortest drilling cycle of 36 days, a 40% reduction year-on-year, establishing a new benchmark for oil and gas exploration in the region [1][3]. Group 1 - The Yuanlu 35HF well reached a depth of 3786 meters and features a wellbore diameter of 419.1 millimeters, overcoming significant geological challenges such as sandstone and mudstone interlayers, which are prone to collapse and leakage [1][3]. - The drilling team implemented an integrated "geology-engineering-production" collaborative mechanism, forming a joint task force to address on-site issues promptly and ensure efficient production [3]. - The "three management" model introduced by the company has significantly enhanced efficiency, with standardized technical measures improving single-run drilling efficiency by 40% [3][4]. Group 2 - The Yuanlu 35HF well set nine records, including the highest single-run footage for PDC bits at 867 meters, the highest mechanical drilling speed at 6.71 meters per hour, and the deepest well with a diameter of 419.1 millimeters at 3786 meters [4]. - The successful completion of the well provides strong technical support for future drilling and oil and gas exploration in the Sichuan Basin [4].
