The Method Of Identifying And Application Of Reservoir Heterogeneity Unit

This article is on the basis of former research of heterogeneity unit, through the research of methods of identifying heterogeneity unit, base on the data of core analysis, associates the difference of physical property and lithologic character of San-Jacinto oil field of the block 1-AB in Peru, classify four heterogeneity unit in layer Vivian and Chonta, within the heterogeneity unit, reservoir character and property are similar, but the property is different between different unit. Based on above information, establish four type models of log interpretation; achieve log interpretation by the restriction of heterogeneity unit. Thereby improve the precision of log interpretation at a certain extent. Then takes the data of reservoir test as standard, adjust the permeability of log interpretation. Permeability is adjusted is greater then primary permeability in layer Vivian and Chonta, and the permeability is adjusted reflects the real infiltrating fluid character, the precision of log interpretation of permeability is improved, then provide reliable data for model building and numerical simulation.
