用于测定液体渗透性的有效压力P_c可以表示为(P_c—SP_p),其中P_c是围限压力,P_p是孔隙压力,S是取决于裂隙面形状和岩石类型的系数。对液体流经由卡兰斯(Kranz)等人模拟的裂隙进行测量其结果表明,S可以在0.5～1.0之间变化。本文认为~(1/3)应该与lnp_c具有线性关系。从卡兰斯等人,伯拉及斯太斯克(Brar和Stesky)和焦尼(Jones)等人所研究的资料来看,都遵从这种理论关系。概述
The effective pressure P_c for determining the liquid permeability can be expressed as (P_c_SP_p), where P_c is the confining pressure, P_p is the pore pressure, and S is a coefficient that depends on the shape of the fracture face and the rock type. The measurement of the liquid flow through cracks simulated by Kranz et al. shows that S can vary from 0.5 to 1.0. This paper holds that ~(1/3) should have a linear relationship with lnp_c. From the data studied by Carranth et al., Brar and Stesky, and Jones et al., they all follow this theoretical relationship. Overview
