绳索取芯技术应用中的井壁稳定性研究
Study on Wellbore Stability in the Application of Wireline Coring Technology
摘要
Abstract
As the deep hole drilling environment becomes more and more complex,the phenomenon of well wall instability during the imple-mentation of rope coring drilling technology becomes more and more prominent.In order to solve this technical issue,the factors leading to well wall instability in the process of rope coring were discussed in detail from both geological and engineering factors.Taking the key investi-gation hole DZK4 in a major water supply project as an example,the synergistic anti-collapse theory of"cation-high adhesion-wetting rever-sal-chemical inhibition-reasonable density support"was proposed in combination with the actual situation of deep hole and complex rock for-mation,and the drilling fluid formula was formed in combination with this theory.The application shows that the density of drilling fluid,wa-ter loss and other related indexes meet the control standard of drilling fluid,and the performance of drilling fluid is more stable.关键词
