摘要
在稠油开采中,储层岩石力学及应力特征对钻井、完井和注汽开采全过程的影响比其它类型油层均更为显著。提出了新疆浅层稠油砂岩在钻井和完井阶段静态固-液耦合的岩石力学特征和表观弹性常数的概念,并对新疆超浅层稠油油藏水平井进行热弹塑性应力分析。在以上基础上分析了新疆超浅层稠油油藏水平井井眼稳定性问题。
For the viscous crude recovery, the influences of rock mechanics and stress characteristics of reservoir on drilling, completion and gas injection development are more clear. Presents the concepts of rock mechanics features and apparent elastic constant of static solid--liquid coupling was pressented in drilling and completion stage in shallow sandstoneviscous oil reservoir in Xinjiang, northwest China. This paper analyzes the thermo-plastoelastic stress of shallow inspissated pool. Based on the above analysis, this paper discusses stability of the horizontal wellbore in ultra--shallow inspissated pool in Xinjiang.
