摘要： 陆梁地区水化学研究表明,研究区内发育多向型水化学剖面,可以划分出三个水文地质旋回:第一水文地质旋回C—T,属于深层静止开放的滞流型水动力系统。第二水文地质旋回J1b-J2x,属于中层弱开放的压实驱动型水动力系统。第三水文地质旋回J2t~K(J2t可属于过渡带),属于浅层强开放的重力驱动型水动力系统;在中部侏罗系矿化度偏低,出现较高—低—高的水化学剖面,说明水动力作用最强烈地带发育于三叠系和侏罗系八道湾组之间的不整合面;CaCl2型水在深部及浅部皆很发育,油气显示层位多,一方面说明它们是油气成藏的有利区,另一方面也说明断裂是良好的运移通道。

Abstract: The hydrochemical study shows that the multi-directional hydrochemical sections developed in research zone of Luliang area can be divided into three hydrogeological cycles. The first one (C-T) is a deep, static and opened lag-style hydrodynamic system; the second one(J1b-J2x) is a mid-depth, weakly opened compacting drive hydrodynamic system; the third one (J2t-K) 1belongs to shallow, strongly opened gravity drive hydrodynamic one. In the middle Jurassic, the salinity of water is relatively low, appearing higher-low-high hydrochemical section,which shows the most intensive zone by hydrodynamic process might develop in the unconformity between Triassic and Badaowan formation of Jurassic;the CaCl2, water type occurs in deep and shallow formations with multi-layer petroleum bearing shows, revealing that they could be favorable areas for petroleum accumulation, and the faults are good channels for oil-gas migration channels.

Key words: Junggar basin, Luliang area, hydrodynamic condition, petroleum migration, petroleum accumulation
