摘　　要：鄂尔多斯盆地东部储层致密、非均质性强,具有一井多层,单层低产的特征。为了进一步提高单井产量,开展了直井机械封隔器多层连续分压技术试验,实现了不动管柱一次分压 6 层的记录,有效缩短了试气周期,施工效率大幅提高,为盆地东部低渗储层经济有效开发提供了技术保障。In the east of Erdos Basin, the reservoir is fine and close, aeolotropism is seriously. The characteristics are one well have many layer and low-duty in one layer. In order to fur- ther enhance individual well producing rate, we run an experiment about mechanical packer of multilayer continuous separate layer fracturing technique at vertical well. This experiment realized the record of immovable string and separate six layers fracturing once, which cut down the test cycle time effectively, raise work efficiency by a wide margin. This experiment provide technique guarantee for economic and valid develop low permeable reservoir in the east of basin.
