大港探区湖泊浅水滩、坝油气藏勘探浅析

Analysis on Exploration of Lake Shallow-Water Beach and Bar Oil and Gas Reservoirs in Dagang Exploration Area

隐蔽油气藏勘探在大港油田油气勘探中发挥越来越重要的作用,文中对该油田隐蔽油气藏中较为特殊的湖泊浅水滩、坝油气藏从储层的形成机理到最终的成藏进行了较为全面的剖析。主要内容包括:湖泊浅水滩、坝沉积学特征和湖泊浅水滩、坝油气藏类型及勘探实例介绍、勘探方法研究、勘探前景分析等。通过分析明确了该类油气藏成藏关键条件及分布的构造部位,为该类油气藏的寻找提供了理论依据。

This paper makes full analysis of the mechanism of oil and gas migration and accumulation for the special reservoirs, such as lake shallow-water beach and bar oil and gas reservoirs, in the subtle oil reservoirs of this oilfield. The main content covers lake shallow- water beach, bar sedimentary characteristics and lake shallow-water beach, bar oil and gas reservoir types and briefings about exploration cases, study of exploration methods and analysis of exploration prospect. The analysis clarifies the key conditions for the migration and accumulation of the oil and gas reservoirs and distribution of structural locations, providing the theoretical basis for search of the oil and gas reservoirs of this type.
