含油气区带评价方法探讨

以含油气区带为研究对象，结合油气探明程度及勘探工作量密度，按勘探程度和油气发现情况将区带划分为评价、预探、区探3种类别。分别考虑油气发现概率和资源战略价值两类因素优选出评价参数，建立了评价、预探、区探3种不同类型区带的评价模板，并提出了对应的评价量化指标和参数体系。利用不同类型评价模板，实现了不同地区相同类型区带在同一平台上的统一评价优选。

A discussion on methods of play assessm ent

According to exploration maturity and oil/gas discoveries，plays are divided into three categories，namely play in appraisal，play in prelim inary prospecting，and play in regional prospecting.Appraisal parameters are selected according to probability of obtaining a discovery and strategic value of petroleum resources.Templates are built for evaluation of theses three types ofplays by using these parameters，and corresponding quantitative indices and parameter systems are also established.W ith theses templates，sim ilar plays in different regions can be appraised and selected on the same platform according to the same standards.
