摘　　要：针对渤海湾盆地中、浅层非典型隐蔽油气藏在油气层评价及开发过程中所暴露出的解释符合率低、含水率高等问题,通过分析储层非均质性与油水分布之间的关系,研究非典型油藏中油水分布非均一性产生的原因,确定渤海湾盆地中、浅层非典型油藏存在2类流体非均质现象,非均质控油作用不仅造成中、浅层流体性质评价困难,同时也使油井投产后产液特征复杂化。The non-typical subtle hydrocarbon reservoirs in middle-shallow Bohai Bay Basin show problems of low coincidence rate and high water cut in the process of reservoir evaluation and development.The relationship between reservoir heterogeneity and oil/water distribution has been analyzed.Two types of fluid heterogeneity are determined for the middle-shallow non-typical reservoirs in Bohai Bay Basin.The control of heterogeneity on oil distribution results in the difficulty in fluid property evaluation and complicates the characteristics of production fluid after putting into production.
