摘要:

通过金湖凹陷典型探井的声波时差曲线分析,论述普遍存在的欠压实现象,并解释当前的油气藏格局。油气的分布虽受多种因素控制,但初次运移输导层砂体常常是油气富集成藏的最有利部位,进而纵向多参数评价研究区古近系烃源岩生排烃范围,以明确下步有利勘探目标。

Abstract:

By analyzing time deference curves of sonic logs of typical exploratory wells in Jinghu sag,this paper presents the undercompacted phenomena generally existing in the sag and interprets current patterns of oil and gas reservoirs.Though the oil and gas distribution was controlled by multi-factors,sand bodies for the primary migration translocation were the most advantageous position for oil and gas accumulation.The hydrocarbon generation and expulsion range of palaeogene source rocks in the study area is evaluated by longitudinal multi- parameters.The beneficial targets for further exploration are proposed.
