摘要
伊深1井在柴达木盆地三湖地区新近系狮子沟组试气获得工业气流,指示新近系狮子沟组中可能存在生物气。为突破柴达木盆地一直局限于第四系寻找生物气的局面,拓宽生物气的勘探领域,采用钻/测井、地震及米兰科维奇旋回相结合的方法,对三湖坳陷北斜坡新近系狮子沟组进行高分辨率层序地层学研究。狮子沟组相当于一个三级层序(长期基准面旋回),在狮子沟组可识别出6个层序界面,进而划分出5个四级层序(中期基准面旋回)。每个层序内部可进一步划分为基准面上升半旋回和基准面下降半旋回。层序Ⅲ(Sq3)基准面上升半旋回时期发育的三角洲前缘砂体尖灭及砂岩透镜体圈闭是进一步勘探的有利目标。
Yishen-1 well has obtained commercial gas flow in the Neogene Shizigou Formation.Results show that the Sanhu area of the Neogene Shizigou Formation has biogenic gas,but the study of the Neogene in Sanhu area is very poor and lack of drilling targets.In order to make a breakthrough of the situation to find biogenic gas in the Quaternary and widen the biogenic gas exploration field,this paper combined drilling/logging,seismic and Milankovitch cycles to study the high resolution sequence stratigraphy of the Neogene in Sanhu depression,Qaidam basin.Results show that Shizigou Formation equals to a Ⅲ sequence(long-term datum plane cycles).Six sequence boundaries can be further identified and divided into five Ⅳ sequence(medium-term datum plane cycles) in Shizigou Formation.Each sequence can be further divided into half cycle of increasing and half cycle of descending.The delta front sandstone thinning out and sand lens trap which develop in half cycle of increasing period of Sequence III(sq3) are favorable target for further exploration.
