Washing Tool 360-Degree Fluid Ejection for Oil Well Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning tools struggle to effectively reach and clean hard-to-reach components in oil and gas wells, such as the internal surfaces of tubing and casing, due to their limited ability to extend beyond their maximum diameter and manipulate components while cleaning.
Innovation Solution
A washing tool designed to eject fluid along a 360-degree circumference without rotating, allowing for effective cleaning of internal pipe diameters with varying sizes, and capable of manipulating components to spray fluid in hard-to-reach areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional mechanical cleaning tools are used, then they can contact and clean material within their maximum diameter, but they cannot extend out beyond their maximum diameter to clean larger sections of pipe
Solution Approach 1:
The patent transitions from mechanical contact cleaning (1D/2D surface contact) to fluid ejection cleaning (3D volumetric coverage). The fluid ejection system projects cleaning fluid in multiple directions simultaneously, enabling the tool to clean areas beyond its physical diameter without extending its length.
2Productivity
If motorized components are added to conventional tools, then cleaning capability is improved, but the tools become susceptible to failure
Solution Approach 1:
The patent replaces motorized mechanical cleaning components with a fluid-driven cleaning system. High-pressure fluid ejection eliminates the need for motors, rotating brushes, or other mechanical moving parts that are prone to failure, while maintaining effective cleaning capability.
Solution Approach 2:
The invention uses hydraulic fluid ejection at high pressure to perform cleaning functions that would otherwise require mechanical power. The fluid pressure and flow dynamics provide the cleaning force, replacing electrical motors and mechanical drive systems.
3Area of stationary object
If the tool is designed to eject fluid along 360-degree circumference, then cleaning coverage is improved, but the device complexity increases
Solution Approach 1:
The 360-degree outlet is divided into multiple discrete ejection ports or nozzles distributed circumferentially around the tool body. Each nozzle handles a specific angular sector, and collectively they provide complete circumferential coverage. This modular segmentation simplifies manufacturing and assembly compared to a continuous complex outlet structure.

AI summary
The present disclosure includes a cleaning system for cleaning clean a tubing, casing, or components of an oil well. In some aspects the cleaning system includes a washing tool having a body configured for insertion into a component of an oil well. The body may include a proximal end and a distal end and define an inlet at the proximal end, a channel in fluid communication with the inlet, and an outlet in fluid communication with the channel. The outlet my extend circumferentially along a perimeter of the body. In some configurations, the washing tool may be configured to clean the component by ejecting fluid in a 360 degree range without movement of the tool.
