【摘要】 采用自制的ZH-1型等围压三轴水力压裂仪,对岩盐水力压裂中围压和轴压(水平地应力和铅直地应力)对破裂压力的影响规律进行了实验研究,得到了本文实验所用岩盐破裂压力与围压和轴压间呈线性关系的经验计算公式。更多还原

【Abstract】 This paper experimentally studies the influence of confined and axial pressures (horizontal and vertical in-situ stresses) on the breakdown pressure of hydraulic fracturing with rock salt by the common triaxial hydraulic fracturing device of ZH-1. The experimental formula of breakdown pressure linearly related to the confined and axial pressures for the rock salt used in present work are obtained.更多还原
