摘要
顺北56X井是顺北V号条带的一口重点预探井,该井完钻井深9300 m(垂深8087.94 m),井底静止温度最高达178℃。储层钻遇断裂带,地层破碎。特深、高温等复杂地质条件给该井定向钻井带来了一系列挑战:摩阻扭矩大、工具面调控难、轨迹控制难、井底温度高、仪器故障率高、破碎带地层定向钻井风险高等。针对上述问题,通过开展井身剖面优化、高温随钻测量仪器优选及工艺配套、定向钻头优选、工具面快速调控工艺研究、降摩减阻工艺配套、地震数据随钻修正指导钻井技术应用和极限延伸能力安全评价,初步形成了特深水平井定向钻井技术体系,实现了亚洲陆上首口井深超9000 m特深水平井安全成井,为顺北油气田特深油气藏勘探开发提供了技术支撑。
The Well Shunbei 56X is a key pre‑exploration well in the Shunbei V belt area.This well is completed in total depth of 9300m and vertical depth of 8087.94m.The static temperature at the bottom of the well is up to 178℃.Because there is fault zone in the reservoir stratum with complex geological condition such as broken strata,ultra‑high depth and high temperature,challenges exists when drilled such as high friction and torque,difficult trajectory control,high failure rate of MWD,high bottom temperature,high rate of instrument broken and so on.In view of such technical problems,directional drilling technology system in ultra‑deep well is built through optimizing the borehole trajectory,high temperature measuring instrument while drilling,drilling craft process,directional bit,fast control of tool face,drilling with the guidance of seismic data,and safety evaluation of ultimate extension capacity.The Well Shunbei 56X is the first horizontal well with the total depth exceeding 9000m in onshore Asia.The technology applied in Shunbei 56X well can provide technical support for exploration and development in Shunbei Oil&Gas Field.
