年度再添两口“优质井”

Core Points - The article highlights the achievements of Shengli Petroleum Engineering Company's Tarim Branch, where two wells, TH103110X and TP1120DH, were recognized as "high-quality wells" during a recent evaluation meeting [1] - The company has a total of 12 wells participating in the evaluation, with 6 of them awarded the "high-quality well" status, ranking among the top in the region [1] Group 1 - The TH103110X well, located in the Tar River 12 area, was developed as a three-opening well, completing the drilling cycle in 33.33 days, which is shorter than the assessed cycle of 36.5 days [1] - The well's depth trajectory met design requirements, and it achieved excellent wellbore quality, with qualified mud quality and oil-gas layer protection, ensuring safe production without accidents [1] Group 2 - The TP1120DH well, drilled by the 70751 team, reached a main well depth of 7,417 meters and a vertical depth of 6,690.04 meters, while the branch well achieved a depth of 7,215 meters and a vertical depth of 6,632.25 meters, setting a record for the deepest domestic dual-branch horizontal well [1] - The team overcame challenges such as complex directional trajectories and high friction coefficients during the casing process, achieving safe and efficient production, and providing valuable experience for future branch well deployments [1]
