东濮凹陷油气藏成藏特征差异以及深层油气成藏过程

Differences in Reservoir-forming Characteristics and Deep Hydrocarbon Accumulation Process in Dongpu Depression

东濮凹陷是渤海湾盆地中既富油又富气的凹陷,对于古近系深层油气的开发具有良好的前景。虽然我国对东濮凹陷油气勘探已达到了中等勘探程度,但是关于该区深层油气的成藏机理还不是很清晰,尤其是深层油气的相态演化、油气充注序列、动态成藏机制及其主控因素研究还处于一个起步期。

Dongpu Depression is an oil-rich and gas-rich depression in Bohai Bay Basin, which has good prospects for the development of deep oil and gas in Paleogene. Although the oil and gas exploration in Dongpu Depression has reached a moderate level in China, the mechanism of deep oil and gas reservoir formation in this area is not very clear, especially the phase evolution of deep oil and gas, the sequence of oil and gas filling, the dynamic reservoir formation mechanism and its main controlling factors are still at an initial stage.
