Reconfigurable Drilling Tool Flow Control for On-Site Turbine Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drilling and measurement operations require transporting the tool string to a remote base site for retrofitting the flow kit, leading to downtime and reduced tool utilization due to the lack of flexibility in fluid flow rate adjustment.
Innovation Solution
Implementing multiple flow kits with integrated valves and a valve controller to dynamically control fluid flow into the turbine, allowing for adjustable flow rates without the need for transportation and retrofitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flow kit is retrofitted at a remote base site, then the flow rate can be adjusted to meet different job requirements, but the tool string must be transported away from the jobsite causing downtime and reduced tool utilization
Solution Approach 1:
The flow kit is divided into multiple modular flow control assemblies (FCA1, FCA2, FCA3) that can be independently selected and activated. Each assembly contains flow control valves and flow meters, allowing the system to be segmented into functional units that can be reconfigured without complete replacement or transportation to remote sites.
Solution Approach 2:
The system transitions from a static, fixed flow rate configuration to a dynamic, adjustable flow rate system. Multiple pump assemblies (AP1, AP2, AP3) with controllable valves (V1-V6) and flow meters (FM1-FM6) enable real-time adjustment of fluid flow rates to the turbine, allowing the tool string to adapt to different job requirements while remaining at the jobsite.
2Ease of operation
If multiple flow kits are integrated into the tool string, then flow rate adjustment can be performed at the jobsite without transportation, but the device complexity increases
Solution Approach 1:
Multiple flow control assemblies (FCA1, FCA2, FCA3) are designed with universal interfaces and standardized components that can perform the same flow control function. This multi-functionality allows any assembly to replace another, simplifying the overall system operation despite the presence of multiple components. The assemblies can be selectively activated based on job requirements without requiring complex integration logic.
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 flexible operation to meet various job requirements by varying fluid flow rates and voltage outputs without removing the power generation section from the jobsite, enhancing tool utilization and reducing downtime.
Implementation Method 1
Flow into the turbine is controlled by a flow kit. Currently, during drilling and measurement operations, it is necessary to transport the tool string or BHA from the jobsite to a base site that is remote from the jobsite so that the flow kit of the tool string or BHA can be retrofitted for use in different jobs
Implementation Method 2
The turbine is coupled with and drives a generator, and the generator generates electricity

AI summary
The disclosure provides for systems and methods for controlling fluid flow into a power generation section of a tool string. In one aspect, multiple flow kits are fluidly coupled with a turbine, and flow of fluid into the turbine is regulated by selectively opening valves coupled with the flow kits. In another aspect, a valve is fluidly coupled with the turbine, and flow of fluid through the valve and into the turbine is regulated by opening, partially opening, closing, or partially closing the valve in response to measured operational parameter data.
