Using geologic strata test data to symbolize oil reservoirs geology model

Abstract

The paper makes use of geologic strata test and pressure instauration curve data since the oil-field has been developed to token and evaluate the distributing regulation of reservoir nature in different fault blocks planes and different oil-bearing groups at the near source steeply shore and speediness sedimentary alluvial apron, which limited mini-sedimentary faces and rock boundary. The limited occupy 39.7 percent of the total testing well number. Except for particular wells near faults contain dual medium, most of them show that the reservoir is uniform and multi-layers is not obvious. According to reservoir nature, four grades, which are the higher permeation, high permeation, low permeation and lower permeation etc, have been divided and the lower permeate primarily is priority which accounts for 56.6 percent of testing well number among the tested wells. The defaults appear more in the fault blocks internally and the conformation is complicated and broken up. These researches offer a reference for improving the oil-field development.
