摘要：准嘴尔盒地湖坡百口泉组致密油为新疆油田公司新发现的大油区，在探索长水平段水平并开发过程中，面临砂砾岩地层可钻性差，地层井壁失稳垮娟严重，漏失复杂情况多，平均单井漏失173m"，水平段机械钻速仅2.06m/h，固井难度大等同题。针对以上难点，重点开展了井身结构及并眼轨连优化、EVOLUTION*美油基钻井液、长水平段小间隙图并技术、砂册岩难站地层的钻头选型等站并提速配套技术研究和实践。在玛131区块成功完站了2口2000m长水平段水平并井，站并周期减少27.7%，下套管顺利，固并质量满足大型分段压裂要求，形成了一套适合玛湖地区致密油经济有效开发的钻完并技术。

Abstract: The Baikouquan Formation tight oil in Mahu slope, the Junggar Basin is a large oil province which was newly discov-ered by Xinjiang Oilfield Company. The development of horizontal wells with long horizontal sections is faced with poor drillability of glutenites, serious borehole instability and collapse, complex circulation loss and difficult cementing. Average single-well circulation loss is 173 m and the ROP in horizontal sections is only 2.06 m/h. To solve these problems, a series of supporting technologies for ROP eaeaeeaee eeea similar oil based drilling fluid, small clearance cementing technology for long horizontal sections and bit selection for difficult glutenites. They were successfully used for the drilling of two horizontal wells with long horizontal sections (2 000 m long) in Ma 131 block. Their drilling periods were shortened by 27.7%, the casing was run in the hole smoothly, and the cementing quality could satisfy the require ments of large-scale staged fracturing. Thus, a set of well drilling and completion technologies suitable for the economic and efficient development of tight oil in Mahu area are established. And they can be used as the technical reference for the drilling and completion of domestic horizontal wells with long horizontal sections
Key words: tight oil; horizontal well; quick and optimal drilling; long horizontal section; based drilling fluid; small clearancc cementing
