摘要: 以苏里格气田为例, 运用多元回归分析的方法对常规测井曲线和岩石力学参数之间的函数关系进行分析, 并运用地质统计学的方法建立非均质的岩石力学参数场, 准确认识储层的岩石力学参数。研究结果可以为气田后期水力压裂过程中压裂设计提供依据, 降低压裂设计计算过程中的误差, 有利于得到更为准确的水力压裂裂缝形态, 降低气田开发风险。

Abstract: Based on Sulige Gas Filed, the function between normal logging data and geomechanical parameters can be determined using the method of multiple regression. Depending on the function and geologic statistical method, the geomechanical parameter model can be created. The geomechanical parameter model can provide support for the fracturing design to reduce the error and risk. It is beneficial to improve the accuracy of the hydraulic fracture morphology and decrease the development risk of gasfield.

Key words: geomechanical parameters, multiple regression, geologic statistical method, geological modeling, Sulige Gasfield
