摘　　要：对引起宝浪油田套管损坏的原因之一,泥页岩水化力学的问题进行了研究。分析了泥页岩水化的原理,进行了泥页岩水化应力试验、水化强度试验,并对试验结果进行了拟合,找出了开发过程中地应力的变化规律。The problem, one of the reasons resulting in the casing damage in Baolang oilfield, about hydration mechanics of mud shale is investigated in this paper. Hydration mechanism of mud shale analyzed, hydration stress and hydration strength tested, and the results matched, so as to find out the regulation of the ground stress varying during oil production, and provide based formation for casing design optimization.
