In order to clarify the relationship between pressure and permeability, porosity of pressure-sensitive reservoir,taking kerosene as percolating fluid,using natural drill core of oil field to simulate development process,and run an equilibrium flow experiment with the action of peripheral pressure interconnection.During the experiment,by using core-clamp that can simulate action of interconnection of reservoir multi-stress field,strain vertical and horizontal stress on drill core separately to simulate bearer condition of core in strata.Laboratory findings indicate that the permeability presents exponential decrease with the increase of effective peripheral pressure,and displays a nonlinear relationship.Catulate the flowrate by taking the exponent equation of permeability and pressure into Darcy equation.We can find that there is apparent peak value on the flow curve,the driving pressure differential corresponding to the peak value is the feasible drawdown.

为研究压力敏感储层的渗透率、流量与压力的关系,以煤油作为渗流流体,利用油田天然岩心模拟油田开发过程,做有围压耦合作用下的稳定渗流实验。在实验过程中,利用模拟地层多应力场耦合作用的岩芯夹持器,分别对岩芯施加垂向压力和水平压力,以模拟地层中岩芯的受力状态。结果表明:渗透率随着有效围压的增加呈指数衰减,呈现非线性关系。将拟合的渗透率与压力的指数方程带入达西公式计算流量。发现流量曲线存在明显的峰值,该峰值对应的驱动压差就是合理生产压差。
