摘要
储层的岩石力学参数和地应力特征对压裂设计优化极为关键,目前,通过实验室测定这二类参数较为准确,但获得连续剖面数据难度大,且费用高。本文以实验室测定的纵横声波时差相关关系为基础,利用常规测井资料对泾河油田的杨氏模量、泊松比及地应力进行了计算。通过与实验室测定数据对比,认为计算结果较为准确。利用该法可获得区域上连续分布的地应力参数,对压裂设计的优化具有一定的指导意义。
Rock mechanics parameters and geostress are very important for fracturing design optimizing. It is accurate to get the 2 parameters in the lab while it is expensive and difficult to get continuous profile data. The relationship of longitudinal and transverse wave slowness is the ground of this paper. The Young modulus, Poisson's ratio and geostress of Jinhe Oilfield were calculated by using conventional logging. The computed result is accurate through contrast with experimental data. Continuous profile geostress data could be got by the method and it has some significant guidance for fracturing design optimizing.
