论富油洼陷及其意义

本文主要根据资源丰度对洼陷进行了贫—富分级。通过对洼陷的类型及成因的分析表明,只有富油洼陷及次富洼陷才具备形成大、中型油气田(藏)的资源条件。渤海湾盆地勘探开发近40年,随着勘探难度日益增加,按洼陷进行资源评价,建立富油洼陷概念,对下一步勘探的战略性选择具有重要意义。

Concept of Oil-Rich Subsag and its Significance

This paper classifies subsags into various oil-rich orders mainly based on resource abundance. Analysis of the subsag types and corresponding origins demonstrate that only the types of those oil-rich or sub-oil-rich subsags can be expected to have potentials for accumulating large or medium size oil fields. In Bohai Bay Basin, which has 40 years of explorationand development history, establishing the concept of oil-rich subsag and evaluating the resources of different subsags are of great significance to make strategic decisions, with the increasing difficulties of further exploration.
