摘要
地质风险分析是评价勘探层和勘探目标中可采烃类聚集存在的概率,对评价资源量和经济价值有直接影响。从川西前陆盆地油气勘探实践着手,讨论勘探层和勘探目标的分类方法,分析地质风险因子所包含的内容及所属级别,建立起有最直接评价意义的地质风险分析程序与原则。这对于油公司提高钻前风险评价能力和油气勘探决策水平,制定勘探战略与勘探计划,进行油气区块的竞投标有着巨大的经济效益。
Geological risk analysis has a direct effect on evaluation of the quantity of resource and the economic value. Based on the practice of oil and gas prospecting in foreland basin in the west of Sichuan, this paper discusses the classification methods of prospecting stratum and objectives, analyzes content and grades contained in geological risk factors, and establishes the procedures and principles of geological risk analysis,which is of enormous economic benefit to the improvement of risk evaluation and decision-making capability in oil and gas prospecting and to the formulation of prospecting strategy and plans.
