摘　　要：通过对桥口Es33～4气藏沉积相分析,认为研究区Es33～4主要发育湖底扇和轴向重力流两种沉积相类型。轴向重力流主要分布在西南部桥34～桥35井区;湖底扇主要分布于桥口东翼。在储层沉积相研究基础上,根据储层沉积相类型、岩性特征及物性特征对储层进行了综合评价,将研究区储层划分为3类。Based on sedimentary fades analysis of Es33 gas pool in Qiaokou area, it is considered that there mainly develops 2 types of sedimentary facies of sublacustrine fan and axial gravity flow in Es33-4 section of studied area. Axial gravity flow is mainly distributed in north-west well blocks Qiao 34-Qiao 35. sublacustrine fan is mainly distributed in the east flank of Qiaokou area. On the basis of reservoir sedimentary facies study, the reservoirs are comprehensively evaluated according to the type of sedimentary facies, lithologic properties and physical properties, thus the reservoirs in the studied area are divided into 3 types.
