南黄海盆地海相储层成岩作用与储层发育特征
|
摘要
南黄海盆地与下扬子陆域具有较为一致的沉积构造演化史,全区具有良好的油气成藏条件,油气资源潜力大,特别是中—古生界海相地层有可能是下一步油气勘探的突破新区。以南黄海盆地为主体的下扬子地区海相储层类型包括砂岩储层、碳酸盐岩储层和泥页岩储层三大类。基于岩性特征、成岩作用、储集空间和物性条件等分析,认为砂岩储层有利的储集体主要为裂缝—次生孔隙型,碳酸盐岩储层中未被胶结物充填或者部分充填的孔、缝、洞可作为有利储集体,泥页岩储层中的有利储集空间为高有机质丰度层段中的无机孔隙、有机孔隙和裂缝较发育带。
The application of oil and gas microbial detection technology in the complex water net area,such as the Beihanzhuang Oilfield of the Subei Basin,has shown great advantages to the commercial culturing technology system.As a case study,we selected an oil developing area and an unknown area,where no oil shows have been found,for sample collection,analysis and evaluation.Methane anomalies are found in the oil developing area covered by the complex water net and the proxies in the unknown area without oil discovery are ten times higher than those in the oil developing area.It leads to the conclusion that the area without discoveries so far is not valueless,but has great potential for oil and gas accumulation.It also indicates that the microbial oil and gas detection technology is applicable and should be promoted in the studied region.
