Product Overview
The Multiple Points Rotary Wash Tool is a multi-stage high-speed rotating dedicated downhole cleaning tool developed for coiled tubing well intervention operations, fitted with multiple groups of independent rotary components and distributed jet nozzles to realize continuous full 360° circumferential rotating movement for comprehensive wellbore cleaning.
With multi-point distributed nozzle layout and multi-stage rotary structural design, this wash tool can perform repeated multiple times of high-pressure jet flushing on the same section of tubing or casing inner wall in a single run-in trip, delivering outstanding descaling and sediment removal treatment effect. The optimized internal flow channel and rotary component structure minimize interference and obstruction caused by downhole debris, scale and sand sediment, so the tool can maintain stable and reliable rotating cleaning performance even in complex vertical and horizontal wellbore working environments.
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 overall make-up length specifications, equipped with standard 1" AMMT and 2-3/8" PAC bottom connection threads for universal compatibility with mainstream coiled tubing connectors and wellbore cleaning downhole service tools. Custom outer diameter, multi-point nozzle layout configuration and anti-sulfur passivation coatings are available upon customer technical drawing submission.

Core Features & Advantages
Multi-Stage Multiple Independent Rotary Component Design: Multiple groups of distributed rotary structures and jet nozzles are arranged along the tool body, realizing synchronous full 360° circumferential rotary jet cleaning without dead zones on tubing and casing inner walls.
Repeated Multi-Flushing Working Mechanism: The multi-point staggered nozzle layout enables repeated high-pressure jet impact on the same well wall position during one single tripping operation, greatly improving the removal efficiency of thick hard scale, paraffin and compact sand sediment.
Stable Rotation Performance Adaptable to Complex Wellbores: The streamlined rotary assembly and anti-blocking flow channel design effectively reduce the negative impact of downhole debris, sediment and scale deposits on rotary operation, maintaining consistent reliable 360° rotating cleaning effect in both vertical and horizontal wells.
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", 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 vertical and horizontal well descaling intervention demands.
Multiple Standard Make-Up Length Options: Complete length specifications ranging from 22" to 32" support matching different wellbore depth and coiled tubing tool string layout design requirements.
Standard AMMT & PAC Thread Compatibility: All product models are equipped with universal 1" AMMT and 2-3/8" PAC bottom connection threads, realizing seamless assembly with global mainstream coiled tubing bottom-hole assemblies without extra conversion subs.
Precision CNC High-Strength Alloy Manufacturing: Adopts precision CNC machining integral tool body and multi-stage rotary components, featuring outstanding high-pressure jet abrasion resistance, erosion resistance and structural stability, extending long-term continuous downhole rotating cleaning service life.

Q4: What is the difference between STD standard grade and H₂S sour service grade?
STD standard grade is manufactured for conventional sweet oil wells without hydrogen sulfide corrosive fluid. H₂S sour service grade adopts sulfur-resistant alloy substrate and special anti-sulfur passivation coating to resist chemical corrosion in high-H₂S sour gas well environments.
Q5: What is the standard production lead time for bulk purchase orders?
All standard PN part numbers are kept in factory inventory, goods can be delivered within 7–15 working days. Customized multiple points rotary wash tools with special outer diameters or custom multi-point nozzle layouts require 20–35 working days production cycle, subject to total order quantity.
