摘要
火6井是吐哈油田施工难度最大的一口双靶点大位移定向井,钻井液技术是该井成功钻探的关键。通过分析现场正电胶钻井液技术措施及井下复杂事故的原因,为以后大位移定向井钻遇煤层的钻井工程提供了宝贵的经验。
Well Huo6 is a double target and long displacement directional welt.It is the most difficult well drilled in Tu- ha oilfield so far.Drilling fluid technology is the key to succeed.In this paper,the technology of MMH drilling flu- id was discussed and the eomolications in Well Huo6 were analyzed,which provided valuable experience for other long displacement directional drilling encountering coal seam.
