安塞油田浅层主要位于安塞东,占老区近1/3面积,油层埋深浅,一般不超过1 000 m,潜力油层具有含油层系多,出油井点多,油层厚度小,渗透率低,分布较分散,油水分异差等特点,但它的资源潜力巨大,采用常规方式开发,单井产量低,经济效益差。本文通过对安塞油田地质构造、沉积特征、储量分类评价等方面的研究,为后期有效动用浅层资源提供了一定借鉴。 The shallow Ansai oilfield is mainly located in Ansai East, accounting for nearly 1/3 of the old area. The reservoir depth is shallow, generally not exceeding 1 000 m. The potential reservoir has many oil-bearing strata, more oil wells, smaller reservoir thickness and lower permeability , The distribution is more dispersed, oil-water differences and other characteristics, but its great potential for resources, the use of conventional methods of development, single-well production, poor economic efficiency. Based on the study of the geological structure, sedimentary characteristics and reserves classification of Ansai Oilfield, this article provides a reference for the effective utilization of shallow resources in the later period.
