摘  要:随着油气勘探的深入和勘探程度的不断提高,未发现的剩余油气资源量不断减少,因此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了该区剩余石油可探明储量,结果表明,金湖凹陷剩余石油可探明储量约为(3320~3670)×104t,仍具有一定的勘探潜力。认为勘探效益法作为油气资源评价的一种新方法,由于其合理地回避了油气成因机理问题,计算过程简便且结果可靠,应用前景广阔。With the development of the oil and gas exploration, more and more oil and gas resources are discovered. How much oil and gas remained in mature oilfields is an important question for petroleum geologists. The paper presents exploration benefit method 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 the oil and gas resources evaluation. By the data obtained in 2004, it is predicted that the oil and gas reserve undiscovered in the Jinhu sag is about (3 32043-670)× 10^1t. The application of the exploration benefit method proved that the method slides over the problem of oil and gas genetic mechanism appropriately and reduces the subjective impact on oil and gas resources evaluation, which makes the results of oil and gas resources evaluation more objective. The exploration benefit method is proved to be a simple, straightforward, flexible mean, with which geologists could use statistics as an aid in estimating undiscovered resources.
