摘要
宣页1井是一口评价页岩气资源潜力的探井,设计垂深2570 m,该井主要钻遇中古生界地层,岩性致密,可钻性极值达8~10级,地层倾角45°左右。在分析塔式钻具、偏心钻具、复合钻进、垂直钻井等防斜技术防斜机理的基础上,重点介绍了各种防斜技术在该井试验应用试验情况,并针对各种防斜技术的应用效果进行了评价。
As an exploration well,Xuanye Well 1 was designed 2570m in vertical depth for shale gas resource potential evaluation.The construction was mainly drilling in the Mesozoic-Paleozoic formation with dense lithology,drillability extreme of 8~10 and formation tip about 45.Based on the analysis on the technology and the mechanism of deviation control with tower-type drilling tool,eccentric drilling tool,compound drilling and vertical well drilling;the paper introduced the experimental application of all kinds of deviation control technologies in Xuanye Well 1,and the application effects of all kinds of deviation control technologies were evaluated.
