High-layer oil exploration and sealing verification assembly

The utility model relates to a testable seal assembly used for exploiting oil on upper layer, comprising a division type unilateral flow valve, an upper packer, a communicating tube and a lower packer. The division type unilateral flow valve, the upper packer, the communicating tube and the lower packer are connected in turn from top to bottom. The upper packer is generally a support type packer, and the lower packer is generally an anchor type packer. The division type unilateral flow valve is used for closing a tube column. The well liquid can enter the tube column whereas the liquid in the tube column can not flow out, in order to achieve testing the pressure of the tube column in a closed manner. The sand particle on the upper part the tube column can sink into a tail tube below the tube column. The utility model is used for exploiting the crude oil of the oil layers above the upper packer and sealing the oil layer below the two packers. The utility model is capable of testing the pressure and checking se
