为建立准确的开发地质模型，利用岩心、测井及化验分析资料，详细研究了濮城油田沙河街组辫状河三角洲储层隔夹层的成因类型及分布状况。研究表明，主要沉积成因类型包括：湖泛垂积成因、河漫成因、滞流成因、废弃河道成因、前积及堤岸成因。隔夹层是控制水淹层中油水运动的主要地质因素。

To accurately establish the geological model of development,this article carefully studies the interbedded genetic types and
distribution of the braided river delta reservoirs in Shahejie Fromation of Pucheng Oilfield based on the analysis of core,logging
and laboratory data. The study results show that the main sedimentary origins of braided river delta interbeds include the lacustrine
deposit origin,alluvial origin,stagnation flow origin,abandoned channel origin,progradetion and the embankment origin. The
interbeds are the main geological factors controlling the oil and water movement of waterflooded zones.
