准噶尔盆地中深层薄层叠置砂体储层预测
|
摘要
准噶尔盆地腹部地区前哨低凸带侏罗系三工河组二段油气显示活跃,勘探程度低,潜力较大,为中深层储层,砂体类型为三角洲前缘水下分流河道砂体。针对该类储层埋藏深、砂体薄、侧向叠置、预测难度大的问题,结合去砂技术储层预测方法,利用逐层去砂实验、模型正演、迭代反演等技术手段进行目标识别,对岩性体边界进行精细刻画,识别出14个岩性圈闭,部署预探井1口,试油获得工业油气流,取得了良好的应用效果。该研究能够有效预测前哨低凸带中深层薄砂岩储层,对其他薄层叠置砂体复杂岩性勘探具有重要意义。
The second segment of the Jurassic Sangonghe Formation in the Qiaoshao low-convex zone of Junggar Basin abdomen area is characterized by active hydrocarbon show,low exploration level and great potential. The second segment of the Jurassic Sangonghe Formation is considered as a medium-deep reservoir and the corresponding sandbody is underwater distributary channel sandbody of delta front. Considering the large burial depth,thin sandbody thickness,lateral overlapping and difficulty in prediction,layer-by-layer de-sanding test,forward modeling,iterative inversion ant other means are used to identify the reservoir by combining with reservoir prediction with de-sanding. The lithology boundary is finely characterized to identify 14 lithologic traps. 1 pre-exploration well is deployed and obtain industrial oil flow,which shows a favorable field application.
