随着钻井技术的发展,钻井动力的提高,开发需求的加大,国内各大油田的深层定向井布置越来越普遍了。然而,深层定向井往往会涉及地层不稳定、泥浆性能调整难、携沙困难、井底环境恶劣等问题,这不仅增加了井控风险,也对定向井的技术、仪器设备提出了更高的要求。本文仅从定向井的专业角度,结合NP36-P3001井的施工经验来探讨分析深层定向所遇到的问题与应对措施。 With the development of drilling technology, the improvement of drilling power and the demand for development, the arrangement of deep directional wells in major oil fields in China becomes more and more common. However, deep directional wells often involve instability of stratum, difficult adjustment of mud performance, difficulty of carrying sand and poor environment at the bottom of the well. This not only increases the risk of well control but also raises the technical and instrumental equipment of directional well Claim. In this paper, we discuss the problems and countermeasures of deep directional analysis only from the professional perspective of directional wells and the construction experience of NP36-P3001 well.
