通过对潜江凹陷王场油田潜江组油藏的生烃潜力、沉积体系、储集条件、构造条件、温压条件、油气分布规律、油气生排烃史以及油气运聚史的研究,对油气成藏规律进行了深入探讨,认为研究区潜江组具有较好的成藏条件,其成藏主要受烃源岩展布、优质砂体、断层及背斜构造等因素的控制,在此基础上建立了王场油田油气成藏模式：源内-混源-垂向-侧向多期运聚成藏。王场油田潜江组油藏紧邻生烃洼陷,油气主要分布于王场背斜,油气主成藏期与断层活动期相匹配,油气主要通过断层和砂体进行阶梯式运移,其中断层的侧向封堵性决定了油气的运移方式及成藏方向。

Based on the study of hydrocarbon generation potential, sedimentary system, reservoir conditions, tectonic conditions, temperature-pressure conditions, hydrocarbon distribution, the history of hydrocarbon generation, expulsion and migration of Qianjiang Formation in Wangchang Oilfield, the hydrocarbon accumulation rules were analyzed. The result shows that there are favorable hydrocarbon accumulation conditions in Wangehang Oilfield, and the hydrocarbon accumulation is mainly controlled by the distribution of hydrocarbon source rocks, favorable sand bodies, faults and the revolution of anticline structure. The hydrocarbon accumulation model is established, which is self source and mixed sources, vertical and lateral migration and multi-stage formations of hydrocarbon reservoir. The reservoirs are located around the hydrocarbon generation sags, the hydrocarbon is mainly distributed in the Wanghcang anticline belt, the active period of fault is in accord with the period of hydrocarbon accumulation period, the hydrocarbon is migrated through faults and sand, and the migration pattern and accumulation direction of hydrocarbons are determined by the lateral sealing ability of faults.
