东营凹陷博兴洼陷浊积岩特征及油气藏类型
|
摘要
博兴洼陷浊积砂体主要发育于洼陷的西北部深洼区,是该区岩性油气藏勘探的重点。本文分析了博兴洼陷浊积砂体形成的特殊构造背景和物质基础,详细归纳了砂体的分布规律,并进一步指出了其地震反射特征。在此基础之上,文章将博兴洼陷浊积砂油藏归纳为构造油气藏、构造—岩性油气藏、岩性油气藏及与火成岩有关的油气藏等四种类型,并就其发育部位及特征进行了逐一的描述。
The turbidite sandbodies mainly develop in deep sag area in Boxin Sag,it is key target for the lithology reservoir exploration.The special tectonic background and material basis to form the turbidite in Boxin Sag were analyzed in this paper,the distribution law of the sandbodies was summarized,the seismic reflection characteristics were further pointed out.Based on the studies above,the turbidite reservoirs in Boxin Sag were divided into 4 categories,the structure reservoir,the structure-lithology reservoir,the lithology reservoir,and the igneous rock-related reservoir,their development regions and their characteristics were described one by one in this paper.
