摘　　要：为查明潜江凹陷王场盐构造的油气分布规律,促进油气勘探与开发,在对地震、钻井及分析化验资料综合研究的基础上,分析其盐构造特征、形成机制、成藏特点,认为王场背斜为一个潜四下段盐韵律层上拱形成的北西向隐刺穿长轴背斜,潜二段沉积时期背斜雏形后缓慢隆升,到荆河镇组末期定型;具有临近富烃中心、多套储盖组合和易形成自生自储或古生新储式油气藏的特点。In order to find out the hydrocarbon distribution regulation, and improve exploratory development of Wangchang salt diapiric structure in the Qianjiang sag, the characteristic and formation mechanism of salt structure and the feature of hydrocarbon accumulation is analyzed which is based on comprehensive seismic drilling and analysis data. It shows that Wangchang salt structure is a north-west macroaxis anticline which rhythmic salt layer in the lower fourth segment of Qianjing formation upward and develop. The embryo of anticline uplifted slowly in the fourth segment of Qian- jiang depositional stage and fell into a pattern in the in the Jing - hezhen evolution depositional stage. The characteristics of Hydrocarbon Reservoiring are ：near by the center of the productive hydrocarbon depression;it has many reservoir-sail assembles;self-generation and self-accumulation or palaeozoic-generation and new-accumulatio. The fourth and third segment of Qianjiang formation are important source rock bearing formations. Structural or lithology complex hydrocarbon ac- cumulations is easily formed with preferable material foundation.
