摘要
Abstract
A certain block is a typical Mesozoic low porosity and low permeability complex fault block oil and gas field ,the buried depth of different faulted‐block reservoirs is different .Different embedded depth of the reservoir , porosity and permeability relationship of conventional core analysis is complex , so it is hard for accurate reservoir parameters calculation and reservoir effectiveness evaluation .Through laboratory core analysis ,reservoir permeability is affected by porosity ,pore structure ,reservoir buried depth and other factors ,the relation of porosity and permeability under overburden pressure is much better than that of atmospheric pressure .Based on the knowledge of core analysis and oil test , a model considering reservoir buried depth , porosity and pore structure’ s permeability calculation of atmospheric pressure and overburden pressure is established ,and a new method of overburden pore‐permeability composite index to evaluate reservoir validity is also established .T hey achieved good application effect in practice .关键词
