摘要
作者通过对目的层储集岩岩石学特征及沉积特征的研究，首次阐明沙三１段沉积环境为河流－滨浅湖环境，沉积体系属湖岸沉积体系，储层沉积相为辫状河三角洲相。此成果对于油田滚动开发及勘探选区评价具有十分重要的指导意义。
Abstract By study on the characteristics of reservoir petrology and sedimentology in target strata, the authors first expound that the sedimentary environment of the Sha 3 Member is river shore shallow lake environment, the sedimentary system belongs to lakeshore depositional system, and the sedimentary facies of the reservoir are braided river delta facies. This result has very important directive significance for the rolling development of the field and the evaluation of prospect area.
