九龙山浅层水平井钻井施工的经验教训与建议

HORIZONTAL WELL DRILLING TECHNOLOGY IN SHALLOW LAYER IN JIULONGSHAN BLOCK

水平井是油气开发、提高单井产量的重要技术手段,在九龙山区块珍珠冲储层应用水平井技术进行开发成为必然。但在该区块水平井钻井施工中,遇到了地层研磨性强、可钻性差等诸多施工难点,导致了起下钻次数多、钻井周期长、易发生钻头和钻具事故。龙002-H3和龙002-H2井是四川盆地九龙山地区部署的第一批水平井,通过对龙002-H3和龙002-H2在施工中遇到的难点和采取的对策进行分析,为九龙山构造后续的钻井施工提供宝贵的第一手资料。

The horizontal well drilling is one of the important technical means for oil and gas developing and improving the well production. During horizontal drilling operation in Jiulongshan Block, a lot of drilling difficulties were encountered, such as strong formation abrasive property and poor drillability etc. which resulted in the more make a trip, long drilling cycle and more accident on drilling bit and drilling tools. The drilling difficulties and measures on the Well Long 002-H3 and the Well Long 002-H2 which are the first horizontal wells in Jiulongshan Block in Sichuan Basin were analyzed. It provided the valuable data for the drilling operation of Jiulongshan Block in the future.
