摘　　要：目前海域油气勘探,对地球物理资料依赖性高,但海上地震、地质资料有限,导致研究区精细地质认识不清。东海西湖凹陷H气田目前已认识到断裂是本区成藏关键,本次研究以新采集的海上宽频宽方位地震资料为基础,提高成像精度,运用各种地震解释方法,开展精细构造解释和特征分析,明确断裂特征、演化和成藏规律,并进一步明确气田南部有利区域,指导勘探方向,为类似构造区域研究提供新研究思路。At present,oil and gas exploration in the sea area is highly dependent on geophysical data,but the seismic and geological data at sea are limited,resulting in unclear understanding of the fine geology in the study area.Currently,it has been recognized that fault is the key to reservoir formation in H gas field,Xihu depression,East China Sea.Based on the newly collected offshore wide-band azimuth seismic data,this study improves imaging accuracy,uses various seismic interpretation methods,carries out fine structural interpretation and feature analysis,defines the fault characteristics,and further defines the favorable southern area of the gas field.It can guide the exploration direction and provide new research ideas for the study of similar structural areas.
