摘要
针对江苏句容地区井壁失稳问题的研究 ,通过理论与室内实验确定了泥页岩水化后的水化应力和岩石强度变化规律 ,计算出该地区不同井深不同层位所需的钻井液密度 ,为该地区的钻井液密度设计提供科学依据。
On the basis of theoretical research and laboratory testing on sidewall unstability in Jurong area of Jiangsu Oilfield, variation law of hydrate stress of shale and rock strength are determined. The necessary drilling fluid densities are calculated in different well depth and different level in Jurong area. It supplies scientific basic for design of drilling fluid density in Jurong area.
