新疆三塘湖盆地油页岩（页岩气）三页1井钻探技术

Drilling technology for oil shale (shale gas) Well Sanye1 in Xinjiang Santanghu Basin

摘要:

新疆三塘湖盆地油页岩（页岩气）三页1井设计井深1750 m，要求全井取心。钻进过程中存在缩径、坍塌等复杂井内情况及冬季施工困难等问题。通过采取聚合物成膜泥浆体系、改进取心钻具等工艺技术以及针对性的施工管理措施，有效地解决了深孔钻井技术难题。为该区域油气资源调查评价提供了高质量的实物资料。

Abstract:

Oil shale (shale gas) Well Sanye1 in Xinjiang Santanghu Basin was designed with depth of 1750m and full hole coring. In the drilling process, there were some problems such as wellbore contraction, collapse and drilling difficulty in winter, and so on. Through the adoption of the polymer film-forming mud system, special coring drilling tools and other technical measures as well as specific drilling management measures, the drilling technical problems have been effectively solved. It provides high quality physical data for the investigation and evaluation of oil and gas resources in this area.
