摘要: 为了解决辽河西部凹陷构造圈闭是否含油、含油多少的定量表征问题,对研究区133个构造圈闭进行了地质统计分析和R型主因子分析。研究结果表明,圈闭距离排烃中心的平面距离、所在地点的流体势、盖层厚度、砂体厚度、切割油藏的断层个数等是制约构造圈闭油充满度的主控因素。依据相关性分析和多元回归分析建立了构造圈闭油充满度与其主控因素的多元非线性定量预测模型,选取了未参与模型建立的16个构造圈闭对已建立的预测模型进行了可靠性验证。验证结果表明,85%以上的构造圈闭油充满度理论值与实际值吻合较好。为该区同种类型的圈闭含油性定量预测提供了一种可行的方法。

Abstract:

To solve the quantitative characterization whether structural traps contain oil

or how much they contain in west Sag of Liaohe Depression,133 structural traps are researched on the basis of statistical geologic analysis and R-factor analysis,the results show that the distances between the center of hydrocarbon expulsion and trap,the fluid potential energy,the depth of caprock,the depth of sand bodies and the numbers of the faults cutting the reservoirs are the controlling factors influencing the fullness degree of structural trap.The comprehensive quantitative prediction models between the fullness degree and the controlling factors of structural traps are established.They are examined through selecting 16 structural traps.The validation results of the forecasting models indicate that the value of 85% forecasted fullness degree of the trap is consistent of the factual value,implying that the forecasting method can be used in oil prospection.

Key words: structural trap, oil-bearing, main controlling factors, quantitative model, West
