油气资源评价是油气勘探决策的基础, 其评价结果影响着油气的勘探方向和投资方向。对于已有油气田发现的评价单元, 统计方法更方便、实用和可靠。根据勘探程度、基于帕莱托定律, 应用油田规模序列法对黄河口凹陷资源量进行了评价, 并进行了勘探潜力分析。黄河口凹陷目前约有25个具有经济价值的油气田尚待探明, 剩余资源总量至少达2.59×108m3, 表明该地区具有较大的石油资源和勘探潜力。其中, 渤中28-34中央隆起带、南部缓坡带和西部断阶带为下一步最有利的勘探靶区。

Assessment of hydrocarbon resources is the basis of making exploration decision and have a great influence on exploration direction and investment.According to the exploration degree in Huanghekou Depression the oil resource is predicted and the exploration potential is analyzed by oil field scale-sequence method in terms of the law of Pareto.Study shows that about 25 profitable oil and gas fields in Huang-hek-ou Depression are to be discovered at present.The remaining oil reserve is expected to be about 2.59×108 m3, which indicates a great potential for exploration.Bozhong 28-34 central uplift belt, the south gentle slope belt and the west fault step belt could be the most promising exploration target areas.
