孙虎地区成藏动力学系统中成藏研究

成藏动力学是以中国东部陆相含油气盆地的地质特征为基础,在含油气系统理论的基础上发展起来的一门新兴的石油地质学理论.它是以研究油气成藏过程为核心,以探讨油气聚集和分布规律为目的,从而指导油气勘探工作.本文在总结前人研究结果的基础上,划分出孙虎地区的5个成藏动力学系统;根据该地区油气运移的特征总结出了3种成藏模式,即垂向成藏模式、侧向成藏模式和复合成藏模式;探讨了成藏控制因素及成藏规律.

Study on Dynamic Systems for Forming Oil Reservoirs in Sunhu Area

Pool forming dynamics is a new emerging theory of petroleum geology on the basis of the geological characteristics of the continental petroliferous basin in the eastern China. The theory is derived and developing from the theory of petroleum system. Pool forming dynamics centers on the study of the formation of oil and gas pools, and aims at oil and gas accumulation and distribution rules to guide our exploration work. On the basis of the experience summed by our predecessors in the Sunhu area, five dynamic systems are divided. And according to migration features of oil and gas in it, three models of oil reservoir formation are classified, namely vertical model, lateral model and complex model of oil reservoir formation. Finally, the controlling factors of the reservoir formation and their regularities controlled by various factors are discussed.
