1985年9月,我队在新疆阿克苏县奥陶系石灰岩中首次发现裂缝原油、油迹和大量的晶洞沥青。分布在喀拉塔格南坡阿克苏水泥厂矿山石灰厂至农建师石灰厂之间,东西长约3km 的地带上。集中于下奥陶统丘里塔格群上亚群(O_1ql~2)浅灰色、灰白色中厚层泥-粉晶灰岩之中。岩层主要发育两组共轭节理,属张扭性裂面,纵横交错形成了连通的裂缝网络。在裂面上常见有大片褐色油迹,某些裂缝
In September 1985, our team first discovered fractured crude oil, oil traces and a large amount of crystal cave bitumen in the Ordovician limestone in Aksu County, Xinjiang. Distributed in the southern slope of Kelatag Aksu cement factory limestone farm to build limestone factory, about 3km east of the strip. Concentrated in the Lower Ordovician Churittag Group upper subgroup (O_1ql ~ 2) light gray, gray medium thick mud - pinkstone. Two main groups of conjugate joints are developed in the rock strata, belonging to the tensional fractured surface, and the fractured networks are formed in a crisscross pattern. Common in the crack surface large brown oil, some cracks
