根据中国东部断陷盆地21个标准区的石油资源丰度及其相关地质参数的统计数据,通过对石油资源丰度诸地质因素的相关性分析,确定了其主控地质因素。研究认为,石油资源丰度与评价单元烃源岩的生烃强度、储集层的储层厚度、砂岩含量、孔隙度和渗透率以及圈闭面积系数6大地质因素关系密切。采用地质因素多元回归技术,建立了中国东部断陷盆地石油资源丰度与其主控地质因素之间的统计模型,建立了预测石油资源丰度的数学模型,使石油资源丰度取值更合理和客观,提高了油气资源评价成果的可信度和可比性。

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.
