摘要/Abstract

摘要：

浅层新近系是渤海海域油田储量和产量的主要层系。随着勘探程度的提高，大—中型油气田发现的难度也越来越大。基于渤海海域的勘探实践，结合浅层大—中型油田源外成藏的特性，通过分析油气深层运移与浅层富集的耦合关系，明确了古近系烃源层油气初次、二次运移所形成的"汇聚脊"对其上浅层油气富集、聚集的控制作用，并根据输导体系的组合划分出油气汇聚样式。在"汇聚脊"控藏模式的指导下，渤海海域多个构造带的油气勘探都取得突破，获得一系列亿吨级新发现，由此保证了渤海海域浅层规模优质油气储量持续发现，指导后续勘探进展。

Abstract:

The shallow Neogene is the main strata that affect the reserves and production of oil fields in the Bohai Sea. However, with the improvement of exploration, it is more and more difficult to discover large and medium oil and gas fields in the Bohai Sea. Based on the exploration and practice in the Bohai Sea, the characteristics of shallow hydrocarbon accumulation outside the source in large and medium oilfields, and the analyses of the coupling relationship between the deep migration and shallow enrichment of hydrocarbons, this paper clarifies the control effects of "catchment ridge" formed by the primary and secondary hydrocarbon migration of the Paleogene source bed on the accumulation and enrichment in shallow overlying strata, and classifies the hydrocarbon pooling patterns according to the combination of carrier systems. Guided by the reservoir-controlling mode of the "catchment ridge", several structural belts in the Bohai Sea have made breakthroughs in oil and gas exploration and obtained a series of new discoveries of 100 million tons, thereby ensuring the continuous discovery of high-quality oil and gas reserves in shallow strata of the Bohai Sea, and further guiding the subsequent exploration progress.

Key words: shallow hydrocarbon migration, exploration progress, catchment ridge, pooling pattern, carrier system, Bohai Sea
