济阳坳陷沾化凹陷长堤潜山披覆构造带桩古60井油藏评价

Reservoir Evaluation of Gu60 Well in Changdi Buried Hill Drape Structure With Pile in Zhanhua Sag of Jiyang Depression

对本区构造特征及其发育过程进行了阐述,从构造、录井、测井、测试方面对本井勘探目的层下古生界和太古界储层进行了分析,提出下古生界和太古界裂缝储层比较发育,一类、二类储层较少,三类储层较多的认识。从油源、储层、通道、圈闭方面对本区油气成藏控制因素进行了分析,指出本井目的层下古生界和太古界未成藏的主要原因是油气运移通道位置偏高,导致油气无法进入圈闭。

Structural characteristics of the region and its development process were described, Lower Paleozoic and Archaean reservoir in the exploration layers were analyzed from the aspects of structure, logging, testing. It＇s pointed out that the Lower Paleozoic and Archaean fractured reservoirs have developed, class one and class two reservoirs are less, but class three reservoirs are major. Oil and gas accumulation control factors were analyzed from the oil source, reservoir, trap, channel of this area. It＇s pointed out that the reason to cause that there is not the accumulation of oil and gas in the layer of Lower Paleozoic and Archean is that migration channel position is high, causing oil and gas to not enter the trap.
