| 摘 要： | 巴楚隆起区主体部位的寒武系多为典型浅水局限台地蒸发相、潟湖相沉积,因此不存在与柯坪地块露头区玉尔吐斯组类似的黑色优质烃源岩,仅为含石膏泥质白云岩或白云质泥岩型烃源岩。生烃和排烃过程发生于加里东晚期—海西晚期,储层以微晶白云岩为主,残余颗粒白云岩次之。理想勘探区块位于潟湖边缘斜坡带及后期构造作用较强的断裂带,下部烃源岩与下—中寒武统盐岩—石膏层构成良好的储—盖组合,具备油气成藏基本条件。以巴什托—先巴扎构造带与康塔库木构造带、古董山构造带—卡拉沙依构造带北段间夹区块、和田1井构造带最具优势勘探潜力。

| Abstract: | The main part of the Bachu High represents a restricted platform during the Cambrian. Therefore,the typical shallow marine lithofacies in the Cambrian sequences of this area are dominated by evaporitic or lagoonal sediments. They are not considered as the good source rocks compared to the Cambrian Yuertus Formation in the Kelpin Block,which consists of black organic-rich shales. Instead,source rocks in the Bachu High include gypsum-bearing muddy dolomites or dolomitic mudstones. The generation and migration... |
