摘要：

准噶尔盆地哈山地区发育砂砾岩扇体隐蔽油气藏,而砂砾岩体一般为多期发育、多次沉积的复合体,其内部结构非常复杂,隐蔽圈闭难于识别。文中以哈山地区侏罗系八道湾组下段砂砾岩扇体为例,根据层序地层学原理,通过对单井相层序进行层序界面识别及旋回特征分析,从而实现砂砾岩体沉积期次精细划分,建立了研究区的地层格架。同时,通过对沉积剖面的观察和分析,结合测井、试油等资料,配合区域沉积相研究,在目标区对地层进行对比和小层划分。选取目标砂体,利用沿层属性提取、地震相等多种地球物理技术,准确地识别出哈山地区扇体隐蔽圈闭,并通过钻探试油,喜获工业油流,取得了中国石化在该区勘探的实质性突破,为寻找该区的类似隐蔽性圈闭总结出了一套行之有效的方法。

Abstract:

Coarse-grained clastic fan subtle traps are well developed in the Hassan block of Junggar Basin.However,the coarse-grained clastic deposits are commonly complexes composed of multiple coarse-grained clastic fans deposited at different geological times.As their internal structures are very complicated,the identification of subtle traps is difficult.Taking the coarse-grained clastic fan of the lower Badaowan Formation of the Jurassic in Hassan block as an example,we identified sequence boundaries and analyzed features of sedimentary cycles in single well by using the sequence stratigraphy method,then performed fine division of the deposits stages of coarse-grained clastics,and finally established a stratigraphic framework.Furthermore,sedimentary section,logging and test data,and regional sedimentary facies were integrated to carry out stratigraphic correlation and layer subdivision and select target sandbodies.By using various geophysical techniques such as seismic attribute extraction and seismic facies,we accurately identified the subtle traps in the Hassan block.Commercial oil flow was tested in these subtle traps,marking a big breakthrough of exploration in this block.These methods may be also effective for identification of subtle traps in similar blocks.

Key words: seismic attribute, coarse-grained clastics, stratigraphic correlation, subtle trap, Badaowan Formation, Junggar Basin
