摘　　要：根据大港探区港东油田的实际情况,以储集层的沉积相研究为基础,结合对地震、地质、钻井等资料的研究,分4个层次进行港东一区河流相储集层的滚动勘探:①根据区域精细地层对比和沉积相研究,查明储集层分布;②充分利用地震信息,预测砂岩发育区,指出滚动勘探目标;③应用神经网络储集层预测方法,利用地震信息在砂岩发育区内确定油气富集带,部署滚动勘探井;④根据地震和测井资料,确定油气富集带内单砂体的边界,定量计算单井单砂体厚度。根据预测结果部署的7口滚动勘探井都取得了良好效果。According to the current state of Gangdong Oilfield, a set of means for progressive exploration play on the first block of Gangdong are proposed, that is based on sedimentary facies research and integrated information of seismic, geology, logging, drilling, including: ① to identify the distribution of reservoir according to precise stratigraphic correlation and sedimentary facies research; ②to proposal the targets for progressive exploration based on the predicts of sandstone developed zones according to the seismic information;③to decide the exploration wells by using the seismic data and neural network; ④ to determine and quantitatively calculate the single sand body’ boundary according to the seismic and log information. The excellent results have been got in 7 wells based on the plays that are made according to the predicting.
