Perforation Tool Containment Cover for Safe Transport and Fast Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perforation tools for hydrocarbon wells require separate transportation and assembly of ignition and charge modules due to regulatory restrictions, leading to time-consuming deployment processes.
Innovation Solution
A fully assembled perforation tool design with a tubular housing, charge module, initiation module, bulkhead module, and containment cover that separates and contains explosive charges, allowing safe transportation and direct deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If perforation tools are transported separately in ignition module and charge module, then regulatory compliance is improved, but assembly time and deployment complexity increase
Solution Approach 1:
The tool is divided into separate ignition module and charge module that can be transported independently, then assembled at the well site. This segmentation allows compliance with transportation regulations while enabling efficient assembly through standardized interfaces.
Solution Approach 2:
The ignition module and charge module are pre-assembled with all necessary components and safety features before transportation. This preliminary assembly reduces on-site assembly time while maintaining regulatory compliance during transport.
2Reliability
If perforation tools are assembled at the well site, then regulatory compliance is improved, but deployment efficiency decreases
Solution Approach 1:
Separate transportation of ignition and charge modules enables regulatory compliance while standardized coupling mechanisms ensure rapid assembly at the well site, maintaining deployment efficiency.
Solution Approach 2:
A standardized coupling interface acts as an intermediary between the ignition module and charge module, enabling quick and reliable assembly at the well site without complex procedures.
3Object-affected harmful factors
If explosive charges are contained in a closed housing, then safety during transport is improved, but accessibility for deployment is reduced
Solution Approach 1:
The housing is segmented with a removable cover that provides secure containment during transport but allows easy access at the well site for deployment operations.
Solution Approach 2:
The housing transitions from a closed, secure state during transport to an open, accessible state for deployment through a removable cover mechanism, adapting to different operational requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables safe and efficient transportation of fully assembled perforation tools, reducing assembly time and complying with regulatory requirements while ensuring containment of explosive charges during transit.
Implementation Method 1
The tool has explosive charges that create jets of hot, relatively dense gas, which project laterally into the wall of the well, and into the formation, opening pathways for fluid flow from the formation into the well.
Implementation Method 2
The tool has explosive charges that create jets of hot, relatively dense gas, which project laterally into the wall of the well

AI summary
A transportable well completion tool is described. The transportable well completion tool comprises a housing with a charge module disposed within the housing. The charge module comprises explosive charges. An initiator module comprising a detonator is coupled to the housing, and a bulkhead member is disposed within the housing between the initiator module and the charge module. A containment cover is secured to the housing to cover the detonator. The transportable well completion tool can be transported with the containment cover in place, and the containment cover can be removed to connect the well completion tool to a tool string for downhole deployment.
