ESTABLISHMENT ON OIL RESOURCES ABUNDANCE STATISTICAL MODEL IN EAST CHINA RIFT BASINS

According to statistical data of oil resources abundance and related geological parameters in the twenty one standard blocks in East China rift basins,through to the correlation analysis of various geological factor which affect oil resources abundance,its main control factors have been defined.The study shows that oil resources abundance has close relation between the six kinds of geology factor which are source rock generation hydrocarbon intensity,reservoir thickness,reservoir sand content,reservoir porosity,reservoir permeability and trap area coefficient.Using multiple regression techniques to establish the statistical model between oil resources abundance and its main control geological factor in East China rift basins,to establish mathematic model for forecast oil resources abundance,so as to make it be more reasonable and more objective for oil resources abundance value,enhance reliability of hydrocarbon resource appraisal result.
