摘　　要：利用相关测井资料计算储层岩石的动态力学参数,并通过室内岩石力学三轴实验将动态的岩石力学参数转化为水力压裂工程可用的岩石力学静态参数,提出储层三向地应力剖面的计算方法。以义H井为例,计算连续的岩石静态力学参数和地应力剖面。Using acoustic density and natural gamma logging data, this paper can calculate rock mechanic parame- ters. Actually, the parameters are used in engineering are static, so this paper uses conversion relationship of static and dynamic fitted to calculate static rock mechanics parameters. Actually the tectonic stress must be considered, so combined with the fracturing data and logging data, the tectonic stress coefficients can be calculated. This paper takes the layer of H well for study, based on calculation software, rock mechanic parameters, stress and fi＇acture pressure are got.
