摘要
针对深部地层的特点,结合现场的复杂情况,利用岩性分析与钻井液理化性能分析相结合的方法,探讨了深部地层井壁失稳的机理。结果表明:地层岩性因素是井壁失稳的内在因素,合理的钻井液技术措施对于井壁失稳的控制可起到良好的作用。
According to the characteristics of the deep strata, combining with the complicated situation of the scene,using lithologic analysis and physieochemical performance analysis of drilling fluid,the mechanism of borehole wall instability of deep strata is investigated. The results show that the formation lithology factor is the inner factor of borehole wall instability,reasonable drilling fluid technical measures for control of borehole wall instability can be a Rood role.
