摘　　要：近年来前任针对具有不同油藏特征的区块提出了多种产能预测方法。研究区砂体发育受沉积环境控制,具有分布零散,规模小的特点,同时油藏内油水同层发育。定性方法或单向流理论公式预测研究区产能符合率低。本次研究基于流体渗流遵循的达西定律,主要针对油水同层发育的储层,建立两相流的自然产能和压裂后产能的预测模型。应用测井、试油、相渗、高压物性等资料确定各参数,并按照分级的方式对产能进行了预测,提高了预测精度,为油藏的下一步勘探开发区块优选提供了依据。Recently,many productivity prediction methods have been proposed for blocks with different reservoir characteristics.The sand body development in the study area is controlled by the sedimentary environment,with the characteristics of scattered distribution and small scale.Simultaneously,the oil and water in the reservoir are developed.The qualitative method or the one-way flow theory formula predicted the low coincidence rate of production capacity in the study area.In this study,based on Darcy law followed by fluid seepage,the prediction models of natural productivity and post-fracturing productivity of two-phase flow are established for reservoirs with oil-water development.The parameters are determined by using the data of well logging,oil testing,relative permeability and high-pressure physical properties,and the productivity is predicted in accordance with the classification method,which improves the prediction accuracy.It provides a basis for the next exploration and development of the reservoir and block optimization.
