Wellhead Plugging and Perforating Integration for Remote Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable plugging and perforating operations in petroleum devices suffer from low automation and integration of equipment, leading to high labor intensity, safety risks, and increased operational and personnel costs due to the need for multiple pieces of equipment and manual operation near the wellhead.
Innovation Solution
An integrated plugging and perforating operation system that combines a logging truck, truck crane, and wellhead blowout preventer into a centralized system with a mechanical mechanism, power mechanism, and centralized control room, enabling remote control and automation of operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple self-contained equipment (logging truck, truck crane, blowout preventer) are used for plugging and perforating operations, then the equipment can perform various functions, but the device complexity and number of personnel required increase
Solution Approach 1:
The patent combines the logging truck, truck crane, and blowout preventer into a single integrated operation truck. The mechanical mechanism includes a turntable assembly with telescopic arm assembly and mechanical arm assembly that can perform multiple functions (lifting, positioning, operating blowout preventer). This merging reduces the number of separate equipment pieces and personnel needed while maintaining full operational capability.
Solution Approach 2:
The integrated operation truck is designed as a universal platform that can perform multiple functions: the mechanical arm assembly can operate the blowout preventer, the telescopic arm assembly can lift and position equipment, and the system can handle both plugging and perforating operations. This multi-functionality eliminates the need for separate specialized equipment.
2Productivity
If personnel perform disassembly operations close to the wellhead, then the operations can be completed, but the safety risk increases
Solution Approach 1:
The patent replaces manual mechanical operations near the wellhead with an automated mechanical arm assembly controlled from a centralized control room. The mechanical arm can gripple and manipulate equipment (such as the lubricator) remotely, eliminating the need for personnel to be close to the wellhead during disassembly and assembly operations, thus reducing safety risks.
Solution Approach 2:
The mechanical arm assembly acts as an intermediary between the operator and the wellhead equipment. The operator controls the mechanical arm from a safe distance, and the mechanical arm performs the physical manipulation of equipment near the wellhead, serving as a mediator that eliminates direct human exposure to hazardous areas.
3Extent of automation
If manual operation and low automation equipment are used, then the equipment is simpler, but the labor intensity and operation cost increase
Solution Approach 1:
The integrated operation system incorporates automated control systems that enable the equipment to operate with minimal human intervention. The centralized control room can自动控制 the mechanical mechanisms, and the system includes self-diagnosis and automated operation capabilities that reduce the need for manual operation while managing the complexity through intelligent control.

AI summary
An integrated plugging and perforating operation system includes an operation truck, a wellhead equipment transport frame a centralized control room and wellhead blowout preventers. A mechanical mechanism and a power mechanism are arranged on a chassis of the operation truck. The mechanical mechanism includes a turntable assembly, where a telescopic arm assembly is installed on the turntable assembly, a mechanical arm assembly for logging operation is installed at an operating end of the telescopic arm assembly, and a logging winch assembly and a follow-up winch assembly are arranged at a counterweight end of the telescopic arm assembly to form a counter weight of the telescopic arm assembly. The power mechanism is configured for providing power output to the mechanical mechanism.
