| 摘 要： | 基于测录井资料对比,结合区域构造演化特征,将草湖凹陷侏罗系划分为两个三级层序J-SQ1与J-SQ2。J-SQ1时期气候温暖潮湿,层序发育完整的上升半旋回和下降半旋回沉积,发育辫状河体系和湖泊体系;J-SQ2时期气候逐渐转为炎热半干旱,层序发育不完整,只发育上升半旋回沉积,主要由氧化型湖泊体系构成,发育滨浅湖砂滩、泥滩互层沉积。其中,J-SQ1早期辫状河河道砂体叠置厚度大,储层物性好,上覆中厚层湖相泥岩沉积,是本区有利的储集层段。

| Abstract: | The Jurassic strata in the Caohu depression,Tarim Basin,Xinjiang are divided,on the basis of well logs and regional tectonic evolution,into two third-order sequences J-SQ1 and J-SQ2.During the deposition of J-SQ1 sequences,the climates were warm and humid.The sequence displays the complete rising-falling semicyclic deposits.Till the deposition of J-SQ2 sequences,the climates turned into hot and semiarid ones.The sequences display only the rising semicyclic deposits,and consists of oxidized lacustrine deposi... |
