Torque Resistant Shroud System for Completion Pipes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing gravel packing completion systems face challenges with torque resistance, particularly at the shroud sections, which can lead to unwanted effects during the installation and operation of the system.
Innovation Solution
A torque resistance system is integrated into the completion system, utilizing a multi-section shroud and torque blocks or a base pipe clamp to provide torsional rigidity. This system automatically engages when the shroud sections are closed, utilizing the base pipe to protect the shroud and jumper tubes from torque effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a multi-section shroud is used to enclose base pipe couplings and jumper tubes, then the completion system can be assembled and protected, but the shroud becomes a weak link with reduced capacity for withstanding high torque loads
Solution Approach 1:
The shroud is divided into multiple separable sections that can be assembled around the base pipe coupling and jumper tubes, then closed together to form a complete enclosure. This segmentation enables easy assembly and protection while the closed sections work together with the torque resistance system to withstand torque loads.
Solution Approach 2:
The torque resistance system is pre-installed on the base pipe before the shroud sections are closed. This preliminary action ensures that when the shroud is assembled and closed, the torque resistance system is already in position to immediately provide torsional rigidity and protect against torque effects.
2Object-affected harmful factors
If the shroud is designed to enclose the handling area with base pipe coupling and jumper tubes, then protection is provided, but the shroud lacks sufficient torsional rigidity to resist torque during installation and operation
Solution Approach 1:
The torque resistance system acts as an intermediary element between the shroud and the base pipe. It transfers and resists torque loads, preventing direct transmission of torque to the shroud sections and protecting the enclosed components from unwanted torque effects.
Solution Approach 2:
The torque resistance system combines multiple structural elements (torque blocks, engagement features, and structural components) to create a composite construction that provides enhanced torsional rigidity. This composite structure enables the shroud assembly to withstand high torque loads during installation and operation.

AI summary
A technique facilitates installation of a completion system having sequentially coupled base pipes and a corresponding alternate path system having alternate path shunt tubes. Sequential base pipes may be joined via a base pipe coupling. The alternate path shunt tubes disposed along sequential base pipes are then connected by jumper tubes. Additionally, the base pipe coupling and the jumper tubes are enclosed with a multi-section shroud by closing shroud sections over the base pipe coupling and the jumper tubes. A torque resistance system is employed to provide torsional rigidity along the shroud.
