Interactive Packer Module Ramp Sleeve Zone Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wellbore drilling technologies lack precision in identifying and isolating hydrocarbon production zones from non-productive zones, leading to inefficient hydrocarbon recovery and unnecessary fluid waste, as existing packer systems require manual sequencing and lack effective fluid bypass mechanisms.
Innovation Solution
A packer module with a centralized control system and interactive modules that utilize a ramp sleeve and isolated flow path channel for selective sealing and fluid bypass, allowing for precise isolation and evaluation of zones through a network of packer modules, enabling accurate fluid characterization and profiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual setting tools are used to open and close packers in sequential order, then the sequence and depth can be controlled, but the system complexity increases and requires multiple different types of setting tools
Solution Approach 1:
The patent applies universality by designing a single setting tool that can operate multiple packer modules of the same type throughout the wellbore. The setting tool includes a motor assembly that can sequentially actuate multiple packers using a unified mechanical interface, eliminating the need for different setting tools for different packers and reducing overall system complexity while maintaining precise zone isolation capability
Solution Approach 2:
The patent merges multiple packer modules into a coordinated system where a single setting tool controls all packers. The setting tool combines the motor assembly, drive shaft, and control mechanisms into one integrated unit that can sequentially engage multiple packers, reducing the number of separate tools needed and simplifying the overall deployment process
2Productivity
If flow bypass is incorporated in setting tools, then fluid can flow during opening and closing operations, but the device complexity increases
Solution Approach 1:
The patent applies the nested doll principle by incorporating the flow bypass mechanism within the setting tool's internal structure. The bypass channel is nested within the tool body, allowing fluid to flow through the tool while the motor assembly operates. This integrated design adds minimal complexity while enabling continuous drilling operations during packer actuation
Solution Approach 2:
The flow bypass acts as an intermediary element that mediates between the need for tool operation and continuous fluid flow. The bypass channel provides an alternative pathway for fluid around the packer assembly, allowing the setting tool to perform its function without interrupting the overall drilling and fluid circulation process

AI summary
A packer module with selective control and fluid bypass can be interactive with other packer modules in a system for isolating and evaluating. The packer module includes a motor section, a conversion section, a control section, a sealing member, and an isolated flow path section. The control section includes a ramp sleeve cooperative with the sealing member to set a retracted configuration, an initial sealed configuration, and an isolated sealed configuration of the sealing member. The isolated flow path section includes an isolated flow path channel. The isolated flow path channel can only be opened with the sealing member in the isolated sealed configuration so that a zone formed by the packer module can be isolated and evaluated. Measuring and detecting instruments along the different flow paths through packer module evaluate the fluid properties of the bypass fluids and isolated fluids through the different flow paths.
