摘要/Abstract

摘要： 对鲁克沁构造带进行了断层封闭性研究,发现该构造带现今状态下北东方向断层受挤压强烈,断层封闭性好,而北西方向断层封闭性相对比较差,成藏期恰好相反。成藏期断层的封堵差异性决定了油气分布的总体态势,而现今断层的封闭性特征对油气的保存以及油柱高度有重要的控制作用。最后,对控油断层进行了封闭性模糊综合评价,认为本区断块圈闭的有效性差,不具备大规模聚集稀油的条件,但对稠变到一定程度的稠油能起较好的封堵作用。

Abstract: Based on study conducted for effect evalution of fault sealing of Lukeqin structural belt both at the pre- sent time and at pool-forming time,it is discovered that the structure belt has been strongly compacted in north-east trend and displayed good effect of sealing. While that of northwest trend faults are less good. However, the sealing effect occurred at the time of pool-forming stage is contrary to the above mentioned. The different effect of fault sealing at pool-forming period determined the general configuration of oil-gas distribution, while the current fault sealing features played a dominant role in oil-gas preservation and the. height of oil-column. Finally, the fuzzy comprehensive evaluation was made on the oil-controlling fault, it is recognized that due to the poor effect of this region's fault block trapment,it cannot prov ide necessary conditions for thin crude accumulation in a large scale. But it will show rather good sealing effect for certain viscous heavy crude.

Key words: Turpan basin, Lukeqin, fault, sealed reservoir, geologic history, stress, plugging, evaluation
