| 9. | Abstract : according to sidewall unstable problem during dr illing , the study on sidewall stability is developed . the paper analyses sidewall stress state and sidewall unstable type , and combines with log data and indoor e xperimental result of core . through analysis and calculation , the method of calcul ating slough formation pressure is proposed . by application of the method in 3 wells in yancheng area , result shows that slough pressure section fits in with field practical condition . it supplies some basis for design of drilling fluid d ensity
文摘:针对钻井中井壁失稳问题开展井壁稳定性研究，文中就井壁应力状态和失稳类型进行分析计算，并结合测井资料和岩心的室内实验结果进行分析，建立了一套计算地层坍塌压力的方法，结合盐城地区3口井应用对比，坍塌压力剖面基本吻合现场实际，为钻井液密度设计提供了一定的依据。 |
