| 摘 要： | 根据海外油气勘探的特点,从"两个步骤、五个条件、两个层次"探讨海外油气勘探地质风险评价分析的方法。以油气成藏的五个必要地质条件为分析对象,在初始评价阶段,基于"资料丰富程度、资料品质、地质认识程度"三个方面对区带油气成藏地质条件存在性风险概率进行分析;在后期详细评价研究阶段,充分考虑影响油气成藏过程发生的各项地质条件的次级因素,对研究对象开展多因素综合性地质风险概率分析。

| Abstract: | According to the characteristics of overseas hydrocarbon exploration,starting from the principles of'two steps,five conditions and two levels',the geologic risk assessment methods of overseas hydrocarbon exploration have been discussed.By taking five necessary conditions for hydrocarbon accumulation as analytic objects,at the initial assessment stage,the geological elements existence probability of play were analyzed on the basis of'data quantity,data quality and level of geological understanding';at the detailed assessment stage,the geologic sub-factors which affected the hydrocarbon accumulation process were fully taken into consideration to carry out a comprehensive geologic risk probability analysis. |
