We present a novel approach for directly measuring the permeability of reservoir rocks by an instrument lowered in a well bore. The measurement is made by creating an oscillatory motion of fluids in the pores by acoustic stimulation and by detecting the amplitude response as a phase shift on a nuclear magnetic resonance relaxation signal. A full theoretical description is given. The feasibility of the method has been verified in the laboratory on a set of sandstone and carbonate samples spanning the entire range of practical interest.
我们提出了一种通过下入井筒中的仪器直接测量储层岩石渗透率的新方法。该测量是通过声刺激在孔隙中产生流体的振荡运动,并通过检测作为核磁共振弛豫信号上的相移的幅度响应来进行的。给出了完整的理论描述。该方法的可行性已在实验室中对一系列涵盖实际感兴趣的整个范围的砂岩和碳酸盐岩样品进行了验证。
