| 摘 要： | 通江铁厂河上二叠统长兴组生物礁是在川东北地区地表发现的生物礁的又一代表,通过野外四条剖面的测量及详细的室内研究,可以认为,该区长兴组发育有生物礁及生物碎屑浅滩组合相,圆丘状点礁与浅滩叠置构成纵向上三个旋回的礁、滩复合体。生物礁的造礁生物主要是海绵,含量为20%～50%,附礁生物主要有藻类、有孔虫、蜓类等。储层岩性主要以礁灰岩及生物屑亮晶灰岩为主,岩石白云化程度较低,孔洞较丰富,但多被方解石晶体充填。通过与普光气田地下剖面对比,该区的沉积微相、岩性特征及储层岩石类型,与普光地区有明显差异。

| Abstract: | The Tiechanghe organic reefs developed in the upper permian Changxing formation are another important representative of platform edge reefs in northeast Sichuan basin.By studying the measurement of 4 outcrops and their detailed indoor examining,this paper finds that the reefs here are not just some isolated reefs like Linchang,and Jiaoshutang,but a united Changxing reef-shoal complex.The Changxing formation is mainly made up by platform edge reefs and platform edge shallow shoal facies,and three upwards ver... |
