引言油层渗透率的非均质性,无论在纵向上和横向上都是十分明显的。在水驱油的过程中,它造成注入水沿高渗透带单层突进和在平面上形成舌进,致使油井过早水淹,并使开发指标变坏,因而在开发方案的计算中,必须考虑渗透率不均质所造成的影响。在现行开发方案的概算法中,对于渗透率不均质性的考虑,都是以单层渗透率分布规律为基础的。关于用统计的方法研究渗透率的分布,美国和苏联学者都作过一些工 Introduction Inhomogeneities in reservoir permeability are evident both vertically and horizontally. In the process of water flooding, it causes the injected water to protrude along the monolayer of the high permeable belt and form tongue in the plane, causing the premature flooding of the well and deteriorating the development index, so in the calculation of the development plan, it is necessary Consider the effect of inhomogeneous permeability. In the current development program of the proposed algorithm, the consideration of the heterogeneity of permeability is based on the single-layer permeability distribution law. With regard to the statistical study of the distribution of permeability, some workers in the United States and the Soviet Union have done some work
