The area already entered the development time, through the subtle 3-d seismic interpretation, Redetermined the structure situation of the area, and has determined several favorable faultclosure.
本区已经进入开发期，通过精细的三维地震解释，重新确定了本区的构造情况，并确定了几个有利断层圈闭。

The widely-developed faults made the fault trap being dominant in the oil-gas reservoirs of the first member of Shahejie Formation. The faultclosure decided the extent of hydrocarbon preservation.
在圈闭类型上，断层的广泛发育使沙一段油气藏以断层圈闭为主，良好的断层封闭性决定了油气藏的保存程度。

The hydrodynamic conditions, migration direction of oils and gases, closure condition of the fault are analyzed using the physicochemical parameters of the fluid of the reservoir.
