摘　　要：随着油气勘探的深入,勘探程度不断提高,未发现的剩余油气资源不断降低,成熟探区剩余资源量的多少备受关注。根据苏北盆地金湖凹陷储量发现规律,应用勘探效益法预测该区剩余可探明储量,并简要介绍了勘探效益法预测油气资源的原理和步骤。研究表明,金湖凹陷剩余可探明储量约为(3320～3670)×104t,仍具有一定的勘探潜力;实践证明,勘探效益法作为油气资源评价的一种新方法,由于其合理回避了油气成因机理问题,计算过程简便,结果可靠,应用前景广阔。As the oil and gas exploration goes further,more and more oil and gas resources are discovered.How much oil and gas remain to be discovered in mature oilfields is an important question for petroleum geologists.The paper presents the exploration benefit approach to assess remaining oil potential in the Jinhu Sag,North Jiangsu Basin,and briefly discusses the principles and steps of the exploration benefit method in oil and gas resources assessment.Research shows that the oil and gas reserve undiscovered in the Jinhu sag is about 3320～36701×04t.Practice proves that the exploration benefit method slides over the problem of oil and gas genetic mechanism in reason and reduces the subjective impact on oil and gas resources evaluation effectively,which makes the results of oil and gas resources evaluation more objective.So the method will have broad prospect for application.
