摘　　要：钻井工程、井下作业及采油均需要了解地层的各种压力及力学特性参数．文中介绍了岩石破裂压力、单轴抗压强度、起始剪切强度、就地最小主应力、就地最大主应力及方向和杨氏模量、切变模量、泊松比等弹性参数的计算方法及其在油田工程、地质、采油等领域的应用．对计算方法的适用条件进行了分析讨论．在分析研究的基础上编制了用于生产的软件并设计了汉字图头，为现场提供了各种有用信息．arious pressure parameters and mechanical property'parameters of the formation are needed in well drilling engineering,oil field well servicing and oil production.The method of calculating the breakdown pressure,uniaxial compressive strength, initial shear strength, minimum in-situ principal stress,maximum insitu principal stress and its direction,elastic parameters such as Yang's modulus,shear modulus and poisson's ratio are preented in this paper.The application of this technique in well drilling,oil productiion,geology and so on is introduced in this paper.The limitations of the technique are also discussed.On the basis of the analyses and investigation. software used in production have been programmed, graph heading with Chinese characters have been designed and various useful information has been provided for the oil fields.
