| 摘 要： | 源岩评价是油气资源评价的基础。目前，基于源岩排烃过程模拟结果可对源岩品质、属性和有效性进行综合定量评价。本文采用盆地模拟技术和不确定性分析方法对影响源岩评价的十三种地质因素的作用大小及其相对贡献量进行评价，同时探讨各种地质因素作用下源岩品质评价指数，属性评价指数和有效性评价指数的变化情况及分布概率。

| Abstract: | Source rock evaluation is the basis of oil and gas resource assessment. The quality,the nature(or attribution) and the efficiency of a source rock can be now evaluated by studying hydrocarbon expulsion process of the source rock during its geohistory. This paper,applying the basin modeling and uncertainty analysis methods,studied the effect and the relative contribution of thirteen major geological factors to source rock evaluation,and discussed the probability distribution of the source rock quality evaluation index(SRIQ),source rock nature evaluation index(SRIN) and source rock efficiency evaluation index(SRIE) under the effects of these major geological factors. |
