| 中文摘要:介绍了钻井岩心机械传性的测试方法──三轴应力试验。通过对两地区部分岩心的测试，得出了岩石泊松比、杨氏弹性模量和抗拉强度等岩石力学参数。数据分析表明，岩石油松比和杨氏弹性模量都随围压增加而增大，并给出了经验关系式。 |

| Abstract:A testing method of drill core's mechanical properties, triaxial stress testing, is described.Based on testing of partial cores taken in two areas, some rock mechanical parameters such as Poison's ratio,Young's modulus, tensile strength are determined. Analysis of the data indicates both that Poison's ratio and Young's modulus increase with the confined pressure. The empirical relationship formula is presented. |
