Drilling Tubing Cleaning System and Method
Patent Number: US 9404313 Grant Date: 2016-08-02 Filing Date: 2013-03-13
Overview
Filed on March 13, 2013 and granted August 2, 2016, this patent protects a robust tubing-cleaning apparatus designed to integrate directly with wellhead tubing removal operations. Inventors based in Borger, TX developed a stacked, multi-plate body that houses internal fluid channels, a fluid input, and replaceable spray heads positioned inside a central tubing aperture. The design combines a wiping rubber and a pivoting gate to clean and wipe tubing as it is pulled through the aperture, while engineered weld gaps, pressure rings, and beveled edges protect tubing and enable code welding for high-pressure service. The specification anticipates material selection and threading details to support elevated spray pressures—up to 10,000 psi in exemplary embodiments—and provides for safe integration with diverter valves, pumps, and air-slip controls at the wellhead.
The firm’s drafting captures both mechanical detail and system-level operability, claiming the protected fluid-routing geometry, modular spray-ring assembly, and the plate-stack approach that shields internal passages while bearing upward and downward loads typical of tubing-removal assemblies.
Key Features
- Stacked plate construction with internal fluid channels and weld-ready pressure rings
- Replaceable spray heads and fluid-dispersing ring for adjustable spray patterns and pressures
- Wiping rubber and hinged gate for containment and debris release
- Designed to withstand wellhead loads and integrate with diverter valves
This invention streamlines on-site tubing cleaning and debris management and materially improves maintenance throughput and safety in oil-and-gas well operations.
Invention Details
Abstract: A tubing cleaning system comprising: a body portion, a tubing aperture, a one or more spray heads, a fluid input and a one or more fluid channels. Said body portion comprising a one or more plates. Said tubing aperture through said one or more plates. Said one or more spray heads arranged within said tubing aperture. Said fluid input. Said one or more fluid channels cut into said one or more plates between said fluid input and said one or more spray heads.
Background: SUMMARY (1) A tubing cleaning system and method of use thereof are disclosed. (2) Said tubing cleaning system comprising: a bod portion, a tubing aperture, a one or more spray heads, a fluid input and a one or more fluid channels. Said body portion comprising a one or more plates. Said tubing aperture through said one or more plates. Said one or more spray heads arranged within said tubing aperture. Said fluid input. Said one or more fluid channels cut into said one or more plates between said fluid input and said one or more spray heads. (3) Said method of using a tubing cleaning system comprising: attaching said tubing cleaning system having a tubing aperture to a portion of a tubing removal assembly at a wellhead; removing a portion of a tubing from a casing at said wellhead and sliding said portion of said tubing through said tubing aperture; attaching a hose to said tubing cleaning system; supplying a fluid to said tubing cleaning system through said hose; channeling said fluid through a one or more fluid channels within said tubing cleaning system; spraying a fluid at said tubing with a one or more spray heads; and supporting a one or more forces pressing into said tubing cleaning system. Said tubing cleaning system comprises a body portion comprising a one or more plates, said tubing aperture through said one or more plates, said one or more spray heads arranged within said tubing aperture, a fluid input, and said one or more fluid channels cut into said one or more plates between said fluid input and said one or more spray heads. BACKGROUND (4) This disclosure relates generally to a tubing cleaning system and method of use. Examples of tubing cleaning systems can be found in U.S. Pat. No. 7,409,995 and as disclosed with this application. However, none of the disclosed inventions and patents, taken either singularly or in combination, is seen to describe the instant disclosure as claimed. Accordingly, an improved tubing cleaning system and method of use would be advantageous.
