| 摘 要： | 以实测的流体资料为基础，初步揭示了塔北地区油田水文地质和水文地球化学特征。塔北地区存在两股地下水流，南部生油区为压实水流，由南向北流动，北部为重力水流，由北向南流动，这两股水流交汇于雅克拉和轮南地区，向上封闭式内泄。无论重力水流或压实水流，皆为非海相成因、非浓缩成因溶滤水。表明：油气藏的形成绝大部分是寒武－奥陶纪生油层二次成油的结果。

| Abstract: | Based on the measurements made for the pore fluid,a preliminary approach is carried out to the hydrogeology and hydrogeochemistry of oilfields in the Northern Tarim basin. There exist tow flow systems, the gravity-driven flow system directed from south to north in the south where oil is generated and the compaction-driven flow system directed from north to south.These two flow systems converge in Yakela-Lunnan area and discharge upwards closely. All waters,whether they belong to the gravity-driven flow system or compaction-driven flow system,are formed by dissolution instead of concentiation or marine origin.This indicates an ovewhelming majority of hydrocarbon pools resulted from the second-crop of the Cambrian-Ordovician source formations. |
