摘要
本文以鄂尔多斯盆地马家沟组灰岩中发育的缝合线为研究对象，通过岩石学观察，阴极发光、电子探针、质谱分析资料的综合分析，对该套地层中的缝合线进行了分期分类，进而讨论了缝合线的形成机制和储集意义，建立缝合线形成与构造裂缝充填相联系的配套模式，并讨论了缝合线的演化及其向储渗空间转化特征。
This paper studied the stylolites in Majiagou Limestone, Ordovician, Ordos Basin. Based on analysis of petrology, cathodoluminescence, microprobe and mass spetrography, the classification, genetic mechanism of stylolites and their storage significance have been discussed. A conveyance model of pressure solution and fracture filling are established. And it is pointed out that stylolites can’t form storage space themselves, but could evolve to them and play a role in the formation of reservoirs and improvement of reservoir quality.
