| 摘 要： | 陆梁地区内水文环境从深部到浅部有明显变化,发育多向型水化学剖面。深部为较高矿化度的CaCl2 型地层水,浅层为较低矿化度的CaCl2 型地层水,中层发育低—高矿化度的NaHCO3型水。地层水的这种剖面分布形式与深层逆断裂和中 浅部的正断裂有着密切的关系。据此将研究区划分为 3个水文地质旋回,每个旋回有着不同的水化学特征及发育不同的水化学剖面。研究区的水动力场与油气运聚关系十分密切,早期主要流向是西北至东南及西南至东北方向,中-晚期主要流向是西南至东北方向,与油气运移方向基本一致。

| Abstract: | The hydrogeological conditions in the Junggar Basin from the deep to the shallow potion were obviously different, and there were various hydrochemical sections. High salinity CaCl 2 water was in the deep, lower salinity CaCl 2 water in the shallow, and the lower to high salinity NaHCO 3 water in the middle. The distribution of different water types in the section was considered to be in close association with the lurk thrust fault in the deep and the normal fault in the middle section. The section could be divided into three hydrogeological gyrations, and each gyration had different hydrochemical characteristics and formed different hydrochemical sections. The evolution of hydrodynamics had close relation with hydrocarbon migration and accumulation. The flow directions in the Carboniferous to Triassic were from northwest to southeast and from southwest to northeast, whereas the main flow direction was from southwest to northeast in the Juro Cretaceous. |
