Oil pipe transmission directional fixed-face perforating pipe string

The invention discloses an oil pipe transmission directional fixed-face perforating pipe string, and belongs to the technical field of reservoir transformation. The pipe string comprises an oil pipe connector, a hydraulic safety releasing part, an upper centralizer, an upper rotating joint, an eccentric direction finder, a lower rotating joint, a sand blasting device, a lower centralizer, a packer, a collar locator and a guiding shoe which are sequentially connected. Orientation is automatically completed under the action of gravity through the eccentric direction finder, and the sand blastingdevice is driven to rotate, so that a nozzle of the sand blasting device directly faces preset direction. When the sand blasting device is used for sand blasting perforation of a reservoir, a directional fixed-face hole can be formed, and the hole forms a crack controllable in extending direction in the fracturing process. The crack effectively communicates with existing cracks of a peripheral well network, and the trans
