摘要

导出了无限饱和多孔弹性固体中三维受压平面裂纹问题的两个积分方程。这些方程将裂缝面上的法向牵引力和流体压力与裂缝开度和单位裂缝面积的流体注入速率联系起来。这些方程的一个重要应用是预测储层水驱过程中产生的水力裂缝，以提高油气采收率

Integral equations for the problem of a 3D crack in an infinite, fluid-filled, poroelastic solid

Two integral equations are derived for the 3D problem of a pressurized plane crack in an infinite, fluid-saturated, poroelastic solid. These equations relate normal tractions and fluid pressures on the crack faces to crack openings and fluid injection rate per unit fracture area. An important application of these equations is the prediction of hydraulic fractures induced during waterflooding of reservoirs to enhance gas and oil recovery
