Product Overview
The Multi-Nozzle Wash Tool is a non-rotational dedicated downhole washing tool, specially developed for inner wall cleaning, scale removal and sediment flushing of production tubing and casing. This wash tool is equipped with 12 lateral nozzles arranged at multiple angles to realize all-round multi-angle jet cleaning for wellbore pipe walls; meanwhile, 1 independent downward nozzle is configured to break and flush compact sand sediment accumulated at the bottom of the wellbore.
All nozzle holes on the tool body support flexible configuration matching: operators can install jet nozzles or blank sealing plugs for any port according to actual construction requirements, so as to adjust jet directions, jet flow ranges and cleaning coverage areas to match diverse downhole operation standards.
Two complete service grades are supplied to adapt diverse reservoir environments: STD standard grade for conventional sweet oil wells without hydrogen sulfide corrosive media; H₂S sour service grade manufactured with sulfur-resistant alloy to adapt high-H₂S corrosive sour gas well downhole working conditions.
The standardized product lineup covers outer diameter sizes ranging from 1-1/2" to 3-1/8", with matched inner bore size and overall make-up length specifications, equipped with standard AMMT and PAC bottom connection threads for universal compatibility with mainstream coiled tubing connectors and wellbore cleaning downhole service tools. Custom nozzle hole layout, jet nozzle inner diameter, outer diameter and anti-sulfur passivation coatings are available upon customer technical drawing submission.

Core Features & Advantages
Multi-Angle All-Round Jet Cleaning Design: 12 lateral nozzles are distributed at different circumferential angles, realizing 360° surrounding jet cleaning on tubing and casing inner walls, completely eliminating cleaning dead zones and improving descaling efficiency.
Independent Downward Sand Flushing Nozzle: The built-in single downward nozzle outputs high-pressure vertical jet flow, which can break up compact hard sand sediment accumulated at the bottom of the wellbore and flush loose sand out of the wellbore.
Interchangeable Nozzle & Blank Plug Structure: Every tapped nozzle hole can be freely fitted with jet nozzles or blank sealing plugs, supporting arbitrary adjustment of jet port layout to adapt customized downhole cleaning operation demands.
Adjustable Jet Nozzle Sizes: Multiple specifications of jet nozzles with different inner diameters are optional, which can adjust jet flow rate and jet impact force to match different wellbore pressure and cleaning intensity requirements.
Non-Rotational Stable Working Structure: The tool does not rely on rotary power to realize full coverage cleaning, avoiding stuck risks caused by rotary components and simplifying supporting coiled tubing tool string layout.
Dual Working Condition Grade Configuration: STD standard version applies to conventional sweet oilfield non-corrosive working environments; H₂S sour service version adopts sulfur-resistant alloy base material and professional anti-sulfur passivation coating to resist hydrogen sulfide corrosion in harsh sour gas well conditions.
Full Outer Diameter Size Compatibility: Standard product series covers 1-1/2", 1-11/16", 2-1/8", 2-7/8" and 3-1/8" outer diameter specifications, fully compatible with global mainstream medium-size coiled tubing assemblies for all tubing descaling and sand flushing intervention demands.
Precision CNC High-Strength Alloy Manufacturing: Adopts precision CNC machining integral tool body, featuring outstanding high-pressure jet abrasion resistance, erosion resistance and structural stability, extending long-term continuous downhole cleaning service life.
Multi-dimensional Customizable Technical Parameters: Supports customized nozzle hole layout, jet nozzle inner diameter, outer diameter, bottom thread specification and anti-corrosion surface passivation coatings to satisfy personalized coiled tubing wellbore descaling and sand washing downhole operation requirements.
