摘　　要：为了阐明博兴洼陷浊积岩特征,明确浊积砂体分布规律,利用岩心、测井及录井等资料,绘制连井剖面图和平面展布图,表征了浊积砂体发育情况。研究结果表明,该区沙三下浊积砂体主要有三期,呈东西两个区域展布,物源方向和坡度大小是主要控制因素。为进一步综合评价研究区浊积岩储层特征,明确油藏富集规律提供理论依据,具有重要的理论和实践意义。Recent researches have shown that with the development of exploration in the Boxing Sag,it is urgent to find the new oil reservoirs.In order to clarify the characteristics and distribution of turbidite sandbody,the core and lithology-sensitive logging techniques are used to establish connecting-well section and it represents the development of turbidite sandbody.Results indicate that the development of turbidite sandbody in study area mainly has three stages,which are distributed in east and west regions.The provenance and gradient are the most important controlling factors for the development of turbidite sandbody.Results in this study provide an important theoretical basis and practical significance for further comprehensive evaluation of the characteristics and distribution of turbidites sandbody in the study area.
