摘要: 从成藏组合概念出发,以源岩、运移、储层、圈闭和时间、盖层五个评价要素,归纳总结了东海西湖凹陷各区带评价层成藏特点,结合分层评价和加权叠合,完成多目的层的区带评价工作,是区带评价方法的一种新尝试。Abstract: Analyzing five evaluative factors such as source rock, hydrocarbon migration, reservoirs, trap and timing, and cap rock, pool-forming features of target horizons in all blocks of Xihu Depression were summed up in this article and a new approach to block evaluation was put forward, which integrated sepa-rate layer evaluation with weighting superposition to evaluate block with multiple targets.
