Horizontal well delivery tractor perforating tool

Abstract

The invention relates to a horizontal well delivery tractor perforating tool. A release pup joint, a rotary pup joint, an upper centralizer, a braking pup joint, a magnetic positioning pup joint, a tractor, a lower centralizer, a flexible pup joint, a safe power supplying pup joint, a shock absorber, a perforator and a rolling ball gun tail are successively connected integrally from top to bottomin a screw threaded mode, and a cable headstall is connected with downhole equipment in a threaded mode. The horizontal well delivery tractor perforating tool is adopted in horizontal well perforatingconstruction, the centralizer can always keep the tractor in the middle state to ensure stable working of the tractor, the braking pup joint can provide the resistance required for upwarping horizontal well operation, the flexible pup joint can change the rigidity of the retractor perforating tool assembly to ensure perforating delivery, and the safe power supplying pup joint ensures electrical safety of the perforator and can prevent perforating accidents. The horizontal well delivery tractor perforating tool can be applied to operation under various working conditions such as first sectionperforating, bridge plug seat sealing reperforating and perforating in horizontal well with large vertical ratio, the construction time is short, the working intensity is low, and the horizontal perforation benefit is high.

AI Technical Summary

Benefits of technology

This patented technology solves problems during drilling operations for both horizontal and verticality boreholes. By keeping the trailer inside its middle position while avoiding any issues like excessive pressure drop due to cables being pulled off, it prevents tools getting stuck between them and causing damage. Additionally, this design allows for easy replacement if needed without having to shutdown all production until repaired. Overall, these technical features help maintain smooth functioning of the machine and enhance overall performance.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the efficiency and reliability of oil field operations during drilling operations due to limitations associated with current tools that require multiple steps before being able to perform their function properly or fail over unexpected conditions like clogging pipelines caused by debris accumulation.
