摘要
提出一种以盆地可供聚集气量和可供聚集气丰度为指标迸行合气远景评价的新方法。可供聚集气是指目前盆地中存在的总天然气量，既包括具有工业价值的天然气聚集，也包括无工业价值的天然气聚集。它在数量上等于扣除了排出气损失量的气源岩排气量。盆地的可供聚集气量可利用盆地模拟方法计算。可供聚集气法可以对盆地的含气远景进行比较客观和定量的评价，避免主观因素的干扰。用此方法对国内某盆地的评价结果与目前勘探成果基本吻合。
A new method for natural gas prospect evaluation is proposed in the paper. In this method. the amount and the abundance of gas available for accumulation are the evaluation parameters The gas available for accumulation is the total gas now presenting in the reservoir of a basin, including both accumulated gas and dispersed gas. The amount of gas available for accumulation is equal to the difference between expulsion amount of gas and the escaped amount of gas after expulsion and these values could be calculated by basin modelling. With this method, the natural gas prospect of a basin could be evaluated objectively and quantitat ively.
