克拉玛依油田金龙2井获得工业油流后,历经多轮评价转入开发。2013-2014年,金龙2井区共实施钻井30余口,平均井深4 250 m,目的层为二叠系乌尔禾组和佳木河组。通过优化井身结构,2 0 1 4年相比金龙2井区不下技套井完成9口井,优选钻头与地层达到最佳性能比,采用扭冲工具等新工具强抑制强封堵钻井液配方,与2014年相比,钻井周期节约23.42天,机械钻速提高25.82%,钻机月速提高41.84%。,同队对地层特性、PDC钻头选型、钻井液优化等方面有针对性地进行攻关和现场试验,形成一套适合于区块的优快钻井技术;为该区块和其他区块实现安全、优质、高效提速提供借鉴和保障。
Karamay Oilfield Jinlong 2 wells after obtaining industrial oil flow, after several rounds of evaluation into development. In 2013-2014, a total of more than 30 wells were drilled in the well Jinlong 2 well, with an average well depth of 4 250 m. The target formation is the Permian Wuerhe and Jiamuhe formations. By optimizing the structure of the wellbore, 9 wells were completed in 2014 compared to the Jinlong 2 well and the optimum performance ratio of the drill bit to the formation is optimized. New tools such as a twisting tool strongly inhibit the strong plugging drilling fluid Compared with 2014, the formula saves 23.42 days of drilling cycles, increases the penetration rate by 25.82% and increases the drilling speed by 41.84%. , The same team on stratigraphic features, PDC bit selection, drilling fluid optimization and other aspects of targeted research and field trials to form a set of excellent fast drilling technology for the block; for the block and other blocks to achieve safety , High quality, efficient speed to provide reference and protection.
