The two fields are experimentally confirmed to correspond to the smooth region and the shear lip on the fracture face respectively.
有限元计算和实验测定结果证实了这两部分分别与试样断口上的纤维区及剪切唇相对应。
The loss are divided into the loss by the changing of fracture width and the loss from fracture face to matrix, and the loss model of working fluid is established.
将钻井完井过程中的漏失分为由裂缝宽度变化引起的漏失和裂缝面向基块的漏失两部分,建立了工作液漏失模型。
Moreover, the acid will further etch the fracture face and create deeper channels which leads to high fracture conductivity and better treatment effect even under high closure stress.
酸液在裂缝壁面上进一步刻蚀形成较深的沟槽,即使在高的闭合应力条件下,酸蚀裂缝也能保持较高的导流能力,从而改善酸压效果。
