| 摘 要： | 近几年对鄂尔多斯盆地东南部延长组的石油勘探取得了重要突破,发现了多口达工业油流的油井.盆地东南部紧邻晚三叠世鄂尔多斯盆地湖盆沉积中心,在湖退背景下全盆广泛发育长6厚层砂体,目前已成为油气勘探的主要目标.依据岩心、露头观察等识别出长6沉积类型具有重力流沉积的特征,并认为盆地东南部长6沉积期广泛发育的深水块状砂岩属于受东北... |

| Abstract: | Recently a major breakthrough has been made in the petroleum exploration in southeast of Ordos Basin and many commercial oil wells have been found in this area.The southeast area of the basin is close to sedimentation center of Triassic Ordos lake basin.The Chang 6 thick layer sandstone is widely developed under the background of lake regression and thus becomes the main target of oil exploration.Based on the large number of the core data and field observations,the sediment of gravity flows was identified f... |
