摘　　要：渤海浅层油藏大多数为胶结疏松的稠油油藏,这类油藏目前主要的开发方式是防砂开采,这样不紧束缚了油田的产量还增加了操作成本.针对渤海稠油油藏的实际情况,提出了适度出砂提高单井产量的开采方式,并开展了实验研究。在调研国内外出砂模拟实验的基础上,利用现有的实验装置,开展了人造岩心制作,采用筛析法和直接出地层砂法进行了适度出砂对储层物性的影响的室内研究,以适度出砂原理为理论基础,同时也与现场的实际生产情况相符合。其研究成果对于渤海稠油油藏出砂油井的科学生产和管理具有一定的指导意义。Most of the Bohai shallow oil reservoirs are loose-cementing heavy oil reservoirs.At present,the development of this tye of reservoir focus on exploitation with sand-prevention.According to the fact of Bohai heavy oil reservoirs,some exploitation methods which can be used to improve the single well production with reasonable sanding are presented in the paper,and experimental researches are done.Having investigated the simulated experiments about sand production at home and abroad,using the existent experiment device,we began to make man-made-cores,and had a laboratory research on the effect of reasonable sanding producation on formation physical property by using serve methods and direct sanding production.Those researches are based on the reasonable sanding production theory and accord with the practical production.The result can guide scientific production and administration in Bohai heavy oil reservoirs.
