摘　　要：对东营凹陷236个砂岩岩性体的成藏主控因素进行了分析,进一步明确了烃源岩条件、储集条件和成藏动力是该类岩性体成藏的主控因素。应用回归法定量分析了岩性圈闭油气充满度与各类地质因素的相关性,建立了断层-岩性圈闭和孤立砂体圈闭油气充满度定量评价预测公式,预测结果与实钻结果吻合程度较高。该成果对提高岩性油气藏勘探开发效益具有指导意义和应用价值。On the basis of geological statistics and multiple linear regression of 236 lithological traps of Dongying Sag,it is clear that the main controlling factors of lithological traps are source rock condition,reservoir condition and dynamics. The forecast formula of oil and gas filling degree of fault - lithological traps and isolated sandbody traps was established according to quantitative analysis of relativity between filling degree and all kinds of geologic factors. The forecast results coincided with factual drilling result. It has guiding significance and applied value for improving exploration and development benefit of lithological hydrocarbon reservoir.
