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.
