| description | The invention relates to the technical field of separate mini-layer fracturing of vertical wells and directional wells for oil and gas field development, in particular to a separate layer fracturing packer. An upper joint, a center cylinder and a lower joint of the separate layer fracturing packer are sequentially connected, an unsetting mechanism, a packing element and a setting mechanism are sequentially sheathed on the center cylinder from top to bottom, the unsetting mechanism and the center cylinder are connected with each other through a slideway and fixed through a shear pin, the setting mechanism comprises a hydraulic cylinder, and a locking mechanism is mounted between the hydraulic cylinder and the lower joint. The separate layer fracturing packer disclosed by the invention has the advantages of great packing and sealing intensity, stable performances and easiness in unsetting, and can meet the requirements of a separate mini-layer fracturing process. The separate layer fracturing packer can overcom |
