摘要:

针对东营凹陷广饶潜山周缘油气成藏期次及富集过程研究难点,展开了成藏关键时刻和油气成藏过程分析。
研究中采用多个层系油水界面统计分析及古油水界面恢复方法,明确了各个含油区块的成因关系。馆陶末期和明化
镇末期是油气成藏的两个关键时刻。由于高砂泥比地层不整合面的遮挡能力十分有限,随着北部生烃洼陷的不断供
烃,多层系油藏围绕大型不整合面不断调整,形成了自北向南多层系逐步调整的动态成藏模式。研究区油气聚集过程
在盆缘区应具有普遍性,这对该领域的油气勘探具有良好的指导意义。

关键词: 大型不整合面, 成藏期次, 古油水界面, 动态调整, 广饶潜山

Abstract:

Aiming at the research difficulty of hydrocarbon accumulation period and enrichment process in the periphery of
Guangrao buried hill in the Dongying Sag,critical moments and process of reservoir forming are analyzed in this paper. Genetic
relationship among oil-bearing blocks is determined through the methods of multi-layer oil-water interface statistical analysis
and paleohydrocarbon-water contact reconstruction. Late Guantao depositional period and late Minghuazhen depositional period
are the two critical moments of reservoir forming. Due to the limited blocking capability of the unconformities with high
sand/shale ratio,with the continuous hydrocarbon supply from the northern hydrocarbon generation sag,multi-layered hydrocarbon
reservoirs constantly adjust around the large scale unconformity surface,and a dynamic accumulation model is formed
which is characterized by gradual adjustment from north to south in multiple layers. Petroleum accumulation in the study area
should be universal and it will be of good guiding significance for petroleum exploration in the similar areas.

Key words: large scale unconformity surface, hydrocarbon accumulation period, paleohydrocarbon-water contact, dynamic
adjustment,
Guangrao buried hill
