苏77-20-7井是苏里格气田一口定向井,设计井深为3259.04m,最大井斜31°,方位22.5°。本文在介绍该井地质概况、井身结构和井眼轨道设计的基础上,对该井施工技术难点进行了分析,阐述了井眼轨迹控制技术,总结了定向井施工经验和认识,通过优化轨迹控制技术方案,采用无线随钻测量仪器实时监测,调整井眼轨迹。实钻结果显示达到设计要求,为提高苏里格气田开发效益积累了经验。
Well 77-20-7 is a directional well in the Sulige gas field with a designed well depth of 3259.04m, a maximum deviation of 31 ° and an orientation of 22.5 °. Based on the introduction of geology, borehole structure and wellbore trajectory design, this paper analyzes the technical difficulties of the well construction, elaborates well trajectory control technology, summarizes the experience and understanding of directional well construction, Control technology program, the use of wireless while drilling measurement instruments real-time monitoring, adjusting well trajectory. The actual drilling results show that the design requirements have been met and accumulated experience in improving the development benefits of the Sulige gas field.
