摘　　要：陆相浊流沉积与海相浊流沉积之间在沉积演化的控制因素方面存在不一致性,其中浊积沉积体系的形成在海相浊流沉积中主要受控于相对海平面变化,而在陆相断陷湖盆中则主要受控于构造沉降、碎屑物质的供给等变化。对梁家楼油田中区的沙三中湖底扇进行了研究,结合湖底扇沉积体系控制因素,划分对比了区内沉积时间单元。The continetal trubidite deposit of its side of ramp is more different than the marine turbidite deposit in terms of control factors of sedimentary evolution.The turbidite system and turbidite stage of the marine deposit are mainly controlled by relative change of sea level.While those of the continental fault lacustrine basin are controlled by the tectonic subsidence and change of debris flux respectively,etc.This paper discusses sublacustrine fan in the middle and lower parts of the third stage of Shahejie Formation in the middle part of Liangjialou oilfield combining with control factors of the tectonic subsidence sedimentary system.The sedimentary cells in work area are classified.
