摘要：

吐哈盆地温吉桑地区自侏罗纪以来的水文地质作用可划分为2个旋回和4个阶段。晚侏罗世晚期至白垩纪以渗透水文地质作用为主,流体交替积极,是油气运移、聚集及油气藏形成的重要时期。温吉桑地区的断裂带附近地层水遭到了渗透水的改造,而远离断裂带的地层水封闭较好。根据UVZ法计算的三间房组的低气势区与已知油气田吻合较好。

Abstract:

Since Jurassic,the hydrogeological function of Wenjisang in Turpan-Hami Basin could be divided into two circles and four stages.From the late stage of Late Jurassic to Cretaceous,infiltration hydrogeological function was predominated and fluid alternation was active.This was an important period for hydrocarbon generation and accumulation as well as for reservoir formation.The formation water near the fault belt in the study area was reformed by infiltration water,but that the formation water far off the fault belt was confined well.The lower energy area of the Sanjianfang Formation that is calculated by UVZ method fits well with discovered oil and gas fields.
