柴达木盆地跃西2平1水平井钻井技术

DRILLING TECHNOLOGY FOR THE HORIZONTAL WELL YUEXI 2 PING-1 IN CHAIDAMU BASIN

跃西 2平 1水平井是青海油田应用水平井技术勘探和开发的第一口水平井 ,也是国内高原地区 (柴达木盆地 )完成的第一口水平井。该井的完成 ,创同类型水平井钻井周期、纯钻时间、平均机械钻速的国内好成绩。施工中 ,积极采用“全压连续钻进”侧钻新工艺 ,并总结、积累了一套系统的高原地区钻水平井的技术资料和施工经验 ,为今后在该地区大面积推广水平井技术打下了良好的基础。

Well Yuexi 2 Ping-1 is the first horizontal well drilled in Chaidamu Basin, and the first horizontal well drilled in the plateau area in China. It sets good records on drilling cycle, net drilling time and average ROP in the same kind of horizontal wells. Full weight on bit (WOB) is applied for continuous drilling during sidetracking, and lots of valuable data and experience is obtained, which is good for pushing the application of horizontal drilling technology in this area.\;
