THE ANALYSIS OF MAIN CONTROLLING FACTORS IN FILLING DEGREE OF THE LITHOLOGICAL OIL-GAS RESERVOIR IN SHENGLI OILFIELD OF JIYANG SAG, BOHAIWAN BASIN
渤海湾盆地济阳坳陷胜利油区岩性油气藏形成的充满度主控因素剖析

By applying the factor analysis method of mathematics geology to pick out the factors which influence the sufficient degree of lothological oil-gas pool in Jiyang sag and determine the main controlling factors of affecting the sufficient degree. Based on the statistical data for the sufficient degree of 137 sand bodies in Jiyang sag to calculate the characteristic value, and make the distribution map of factor loading. The research results demonstrated that, the migrating condition is the first controlling factor to influence the sufficient degree of lothological oil-gas pool in Jiyang sag, the accepting condition is the second controlling factor, but influence of the oil source condition is not decisive, the result indicated that, by comparing to analyze the different depression and the different type lithological oil-gas pool, the main controlling factors for the sufficient degree are basic to be same for the lothological oil-gas pool of different depression; however, the main controlling factors for extent for the lothological oil-gas pool of different type. the sufficient degree are to be different to some
