摘要

准噶尔盆地腹部油气资源非常丰富

其中相当一部分储集在隐蔽油气藏中。准噶尔盆地腹部隐蔽油气藏具有多沉积体系控制、构造-岩性复合、多层系含油以及具有多期成藏的特点。对隐蔽油气藏的勘探既要采用新的研究思路

又要采用现已比较成熟的研究方法。首先开展高分辨率层序划分对比研究

确定隐蔽圈闭发育的有利层位;其次开展古地貌及沉积环境研究

寻找坡折带和有利相带

确定隐蔽圈闭发育的有利部位;再次开展地震处理

发现和落实隐蔽圈闭

寻找隐蔽油气藏。

Abstract

Central Junggar basin is rich in petroleum resources

much of which are accumulated in subtle oil/gas reservoirs. The subtle oil/gas reservoirs are characterized by control of multiple sedimentary systems

structural lithologic combination

multiple oil-bearing layers and multi stage reservioring. Both new ideas and relatively mature methods should be used in exploration of subtle oil/gas reservoirs. Firstly

determining favorable horizons for development of subtle traps through high resolution sequence stratigraphic division and correlation; then looking for slope break zones and favorable facies zones through palaeotopographic and sedimentary environment studies; and finally locating subtle traps and searching for subtle reservoirs through seismic processing.
