对尚未发现油气资源的区域进行评价的一个简单方法,就是根据地质资料估算所勘探的远景区带中潜在油(气)田的数量及规模分布。一个远景区带由一组地质条件,即生油岩、储集层以及控制油气分布的圈闭条件相类似的远景圈闭组成。这种评价方法的最简单形式如图1所示,这是阿特沃特(Atwater)在1956年提出的。具体做法是用远景圈闭数乘以假设的成功 A simple way to assess areas where no hydrocarbon has yet been discovered is to estimate the number and size distribution of potential oil and gas fields in the prospect’s prospect based on the geological data. A long-range zone consists of a set of geological conditions, namely source rocks, reservoirs and prospect traps with similar trap conditions that control the distribution of hydrocarbons. The simplest form of this evaluation method is shown in Figure 1, which was proposed by Atwater in 1956. This is done by multiplying prospective traps by hypothetical successes
