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。

关键词: 准噶尔盆地, 隐蔽圈闭, 沉积体系, 成藏特征, 高分辨率, 坡折带

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.

Key words: Junggar basin, subtle trap, depositional system, reservoiring characteristics, high resolution, slope break belt
