摘要
高温深井环境下钻井液性能将受较大影响,改变原有特性,易造成井壁失稳的现象。文章分析了高温对钻井液性能的影响,并针对高温环境下钻井液体系影响井壁稳定性的因素提出了应对措施。
Deep drilling fluid properties under high temperature environment will be subject to great impact,changing the original characteristics could easily lead to wellbore instability phenomenon.This paper analyzes the impact of high temperature on drilling fluid properties,and propose countermeasures aim at the factors that drilling fluid system affect the wellbore stability under high-temperature environment.
