新场气田东部发育两组走向近南北的逆冲断层，它们提供了该区断弯褶皱、断展褶皱和断鼻构造形成的原动力。根据该区剖面结构和平面特征，划分出合兴场南北向形变域和新场东西向形变域。燕山中、晚期形成的古隆起构成了该区天然气的区域成矿背景，古隆起之上的有利储集相带控制了天然气富集。 Two sets of thrust faults to the north and south developed in the east of Xinchang Gas Field. They provide the driving force for the formation of fault fold, fault fold and fault nose structure. According to the section structure and plane characteristics of the area, the deformable domain of Hexingxing north-south direction and the east-west deformable domain of Xinchang field are divided. The paleo-uplift formed in the middle and later stages of Yanshan formed the regional metallogenetic background of natural gas in the area. The favorable reservoir facies belt over the paleo-uplift controlled the enrichment of natural gas.
