| 摘 要： | 利用岩心观察、薄片鉴定、电子探针和拉曼光谱等分析手段,从缝合线特征描述入手,分析塔河油田缝合线的成因及其油气意义.结果表明:研究区缝合线可分为3种,即顺层缝合线、倾斜缝合线和竖直缝合线;研究区缝合线有压实、压裂和压溶3种成因类型,其中顺层缝合线以压实成因为主,倾斜缝合线和竖直缝合线以压裂成因为主;压实缝合线或压裂缝合线是形成压溶缝合线的基础,而压溶缝合线是压实或压裂缝合线的延续;塔河油田奥陶系碳酸盐岩缝合线比基质有较高的有机质丰度,为油气生成的有利场所,同时为油气的运移提供了有利通道,也有利于提高储层物性.

| Abstract: | By using methods of core observation,thin-section analysis,electron probe and Raman spectrum analysis,the stylolite genesis and its petroleum significance in Tahe Oilfield were described based on stylolite characteristics. The results show that there are three kinds of stylolites including bedding,inclined and vertical stylolite. There are three kinds of genetic types for stylolites including compaction,fracturing and pressolution. Compaction is main contribution factor for bedding stylolite,and fracturing ... |
