摘要
尽管东辛油田馆陶组和东营组钻遇程度较高,但一直以来对其油气成藏控制因素研究较少,特别是油气藏分布规律尚不明确。通过对东辛油田复杂断裂带浅层油气成藏特点的深入研究,明确了油气成藏主控因素包括宏观构造背景、断层、不整合面、砂体形态、复式仓储层的调控等,提出了该区浅层多期复式网毯油气运聚理论,归纳总结了垂向断控型成藏模式以及复式仓储层的向心式调控模式。
Although Guantao Formation and Dongying Formation in Dongxin Oilfield have been drilled by many wells,the research about controlling factors to hydrocarbon accumulation is few, especially the distribution of hydrocarbon reservoirs is still unknown. By analyzing the hydrocarbon reservoir forming characteristics of shallow layers thoroughly in the complex fault zones in Dongxin Oilfield, the main controlling factors of hydrocarbon reservoir forming are known including macro-tectonic background, faults, unconformity, sand-shape, multiple-reservoir control etc. The theory of hydrocarbon migration and accumulation of multiple ' meshwork -carpet'in Dongxin shallow layers is put forward. The reservoir forming pattern of vertical-faulting-controlled type and the regulation control pattern of centripetal control are summarized.
