柴西红三旱一号-牛鼻子梁地区新近系沉积演化与有利区带预测
|
摘要
在高分辨率层序地层学原理和分析方法指导下,通过对野外露头剖面、钻井、测井和二维地震资料的综合分析,在柴达木盆地西部红三旱一号-牛鼻子梁地区新近系中识别出1个超长期基准面旋回(二级层序)Ssq1和4个长期基准面旋回(三级层序):Sq1、Sq2、Sq3和Sq4。识别出2种主要的沉积体系类型:扇三角洲沉积体系和滨浅湖-滩坝沉积体系,并在等时地层格架内分析了各基准面旋回的沉积体系构成及其发育演化。综合分析认为:红三旱一号三高点至不整合地面构造之间的区域为油气勘探的有利区带,Sq1旋回扇三角洲前缘亚相为有利储集体集中发育层段。
One super long-term stratigraphic base level circle(the 2nd sequence)Ssql and the corresponding 4 long-term stratigraphic base level circles(the 3rd sequence)Sq1、 Sq2、 Sq3 and Sq4 could be distinguished in Neogene in Hongsan-hanyihao and Niubiziliang area,Qaidam basin by using the ways and principles of the high resolution sequence stratigraphy.Within the correlation framework,two main type depositional systems are identified,namely fan delta and lake depositional systems and it analyzed the composition of the depositional system and facies development in the cycles.The paper points out that Sq1 cycles is the most favorable reservoir rock,and the rock of the fan delta front is the target of the oil exploration.It also points out such area as be-tween the third high point of the Hongsanhanyihao area and the area of unconformity surface structure is the most favorable region for oil and gas exploration now.
