| 摘 要： | 随着石油工业的发展，人们对于油藏介质──岩石的研究越来越重视。国外近20年来一直致力于研究石油工程问题，如：井筒稳定性、产砂预测、地面沉降及水力裂缝扩展机理等所涉及到的岩石力学问题。本文在一系列试验的基础上，描述了岩石弹性模量对压裂裂缝几何形状、施工压力等的影响，并给出了毕奥特系数的试验方法及其在水平应力计算中的应用。

| Abstract: | With the development of petroleum industry,the study on rock are more and more important. The rock mechanics problems existing in wellbore stability,sand production prediction,land subsidence and fracture extension have been studied for about 20 years in China. Based on many experiments, this paper discusses the effect of rock modulus of elasticity on fracture shape and operating pressure, presents the testing method of Biot coefficient,and introduces its applications in calculation of horizontal stress. |
