摘要：

渗透率合成在石油储量计算、油田开发方案编制、油藏数值模拟等油藏工程研究中经常遇到,主要包括垂向上不同层段渗透率的合成以及沿渗流方向不同渗透率带渗透率的合成。根据达西定律,结合建立的渗流模型,经数学推导,得到两类渗透率的合成公式。其中,垂向上不同层段渗透率的合成公式与前人文献中一致;而沿渗流方向不同渗透率带的合成公式与前人有较大差别。经实测数据检验,用新推导的公式计算所得的结果误差为0.28%～53.5%,基本上在允许的范围之内。

Abstract:

The composite method of rock permeability have always been applied in the calculation of oil reserves,complication of oilfield development plan,numerical simulation of reservoirs and other reservoir engineering research, which mainly include the permeability compositon of vertically different stratigraphic horizons and the permeability composition of different permeable zones along filtrational directions.Based on Darcy's law and combined with established filtration pattern,two composite formulas of permeability have been derived from mathematic calculation.The composite formula of permeability in vertically different stratigraphic horizons corresponds to that in historical literature,but the composite formula in different permeable zone is more different from the forefathers' formula.Based on the examination of actual data, calculated error of new formula is about 0.28%-5.35%,which is basically within permissible error range.

Key words: permeability, reservoir engineering, permeability composition, average permeability
