摘　　要：随着油气勘探程度的不断提高,未发现的剩余油气资源越来越少。如何准确预测高勘探程度即成熟探区的剩余油气资源,成为石油投资者和油气资源评价工作者关注的焦点。详细探讨了油藏规模序列法预测油气资源的原理、方法、操作流程及存在的问题,并运用该方法对东营凹陷剩余可探明储量以油气成藏体系为评价单元进行了预测。研究表明,东营凹陷剩余可探明储量约为17.03×108t,仍具有较高的勘探潜力,并且主要集中在东营中央背斜带和东营凹陷北坡两个油气成藏体系内。实践证明,由于油藏规模序列法合理回避了油气成因机理问题,减少了资源评价工作中人为因素的影响,使资源评价结果更为客观。As the degree of hydrocarbon exploration keeps increasing,the uncovered remaining resource is reducing.The key issue interested by petroleum investors and resource evaluators is how to precisely predict the remaining resource in highly and maturely explorative areas.The authors of the paper probe the principle,approach,operating procedure and the existing problems of predicting hydrocarbon resource by reservoir size sequence,the approach is applied to predict the remaining proved reserve at Dongying sag by taking hydrocarbon accumulation system as evaluation unit.The result shows the remaining proved reserve at the sag is 17.03×108 t,there is still great explorative potential,and the hydrocarbon is mainly concentrated in the two accumulation system,i.e.Dongying central belts and Dongying north sag slope.Case study indicates the consequence of resource evaluation is more objective duo to the approach reasonably avoiding the issue of formation mechanism of oil and gas and minimizing subjective influence on the evaluation.
