摘 要: | 泥页岩井壁失稳问题是钻井工程中经常遇到的难题,针对这一问题的研究从20世纪40年代起就开始进行,20世纪90年代进入了泥页岩井壁稳定的多场耦合研究阶段,出现了多种理论。这些理论不同程度的促进了泥页岩井壁稳定研究的发展。但是,由于泥页岩多场耦合的复杂性,许多参数很难进行实验室测定,使得很多理论都具有局限性和片面性。本文主要研究了影响水进入泥页岩的主要因素:水力压差传递,化学势作用下的扩散;以及泥页岩井壁稳定的对策。

Abstract: | Shale Drilling Project borehole instability problems often encountered problems,Research for this problem 40 years from the 20th century began to make,Of the 20th century into the 90's shale wellbore stability studies of multi-phase coupling,Appeared in a variety of theoretical.These theories contributed in varying degrees of wellbore stability of shale development,But,As the shale the complexity of multi-field coupling,a number of laboratory parameters measured is difficult to make a lot of theories have limitations and one-sidedness.This paper studies the impact of water into the shale of the main factors: the hydraulic pressure transmission,spread under the action of the chemical potential;and wellbore stability of shale response. |
