Product Overview
The Integrated Jetting Sub all-in-one integrated coiled tubing sand jet perforating tool is a multi-function downhole sand blasting perforation construction tool that integrates coiled tubing upper connecting joint and sand jet perforation nozzle assembly into a single unit.
This integrated jetting sub is installed at the bottom end of the coiled tubing string before running the coiled tubing into the predetermined target underground well depth; the tool is specially designed for through-tubing sand blasting perforation construction work, high-pressure sand carrying fluid is pumped from surface through coiled tubing and ejected from the built-in jet nozzles to complete target formation sand jet perforation operation. Multiple independent reverse circulation flow channels are pre-machined inside the main body of the jetting sub, forming complete wellbore return fluid circulation passage during the whole sand jet perforation construction process, realizing effective downhole fluid reverse circulation and well cleaning after perforation. The jet nozzles adopt hard tungsten carbide material with outstanding anti-abrasion and anti-sand-erosion performance, the maximum allowable sand carrying fluid throughput of a single nozzle exceeds 60 cubic meters, which can meet high-volume large-displacement sand jet perforation construction requirements. The outer diameter of the entire integrated jetting sub tool body is completely consistent with the outer diameter of the matched coiled tubing, there is no protruding oversized outer diameter section, effectively eliminate downhole sticking, fishing and other construction safety risks during tripping in and tripping out operations. Two optional internal sealing actuation structural designs are provided for user free selection: ball drop actuated type and blank sealing plug type; two standard coiled tubing connection joint forms are available for matching selection: Roll-On thread connector and Dimple On joint connector. Four standard matching coiled tubing outer diameter sizes are supported: 1-1/2 inch, 1-3/4 inch, 2 inch and 2-3/8 inch, each CT OD corresponds to fixed overall make-up length dimension and dedicated standard connection thread specification, all models adopt STD standard working condition configuration.
The Integrated Jetting Sub has no complex internal movable friction components, spring energy storage assemblies or differential pressure release mechanisms, with extremely simplified wellsite operation flow and low maintenance cost; construction crews only need to connect the integrated jetting sub to the bottom end of the coiled tubing string via selected Roll-On or Dimple On connector, run the whole tool string down along the tubing inner wall to the predetermined target underground well depth, pump high-pressure sand carrying fluid from surface through coiled tubing to eject from tungsten carbide nozzles and complete sand jet perforation operation, the built-in internal reverse circulation flow ports continuously provide full wellbore return fluid passage during the whole construction process to realize well cleaning circulation; after the perforation construction work is fully completed, lift the coiled tubing string together with the integrated jetting sub out of the wellbore to finish operation, no additional complex auxiliary operation steps such as separate ball dropping or plug setting are needed, shortening wellsite operation time and reducing human error risks.
The standardized product lineup covers four standard matching coiled tubing outer diameter sizes of 1-1/2", 1-3/4", 2" and 2-3/8", each CT OD corresponds to fixed overall make-up length dimension and dedicated standard connection thread specification, all models adopt STD standard working condition configuration; custom tungsten carbide nozzle sand throughput capacity, matching coiled tubing outer diameter size and internal reverse circulation flow port layout customization are available upon customer technical drawing submission.

Core Features & Advantages
All-In-One Integrated Structural Design: The tool integrates two core functional components — coiled tubing upper connection joint and sand jet perforation nozzle assembly — into a single integral unit, eliminating separate assembly and connection steps of two independent tools on-site, simplifying wellsite tool string preparation operation flow and reducing on-site assembly failure risks.
Hard Tungsten Carbide High Erosion Resistant Jet Nozzle Design: The jet ejection nozzles are manufactured from hard tungsten carbide alloy material, with outstanding anti-abrasion and anti-sand-erosion performance; the maximum allowable sand carrying fluid throughput of a single nozzle exceeds 60 cubic meters, which can stably meet high-volume large-displacement high-flow sand jet perforation construction long-term operation requirements.
Equal Outer Diameter Tool Body Safety Design: The outer diameter of the entire integrated jetting sub tool body is completely identical to the outer diameter of the matched coiled tubing, there is no protruding oversized outer diameter section, effectively eliminate downhole sticking, fishing and other construction safety risks during tripping in and tripping out operations, lower well operation hazard level.
Built-In Independent Internal Reverse Circulation Flow Port Design: Multiple independent reverse circulation flow channels are pre-machined inside the main body of the jetting sub, forming complete wellbore return fluid circulation passage during the whole sand jet perforation construction process, realizing effective downhole fluid reverse circulation and well cleaning function after perforation construction.
Dual Optional Internal Sealing Actuation Structural Types: Two different internal sealing actuation structural designs are provided for user free selection according to on-site construction operation requirements: ball drop actuated type and blank sealing plug type, adapting to different well construction process schemes.
Dual Standard Coiled tubing Connection Joint Form Choices: Two mainstream coiled tubing connection joint designs are available for matching selection: Roll-On thread connector and Dimple On joint connector, compatible with mainstream coiled tubing end connection specification standards on the market.
Ultra-Simplified Wellsite Operation Logic: The integrated jetting sub has no complex internal movable friction components or spring energy storage assemblies, the operation flow is highly streamlined: connect the integrated jetting sub to coiled tubing bottom via selected Roll-On or Dimple On connector, run the tool string down to the predetermined target underground well depth, pump high-pressure sand carrying fluid from surface through coiled tubing to eject from tungsten carbide nozzles and complete sand jet perforation operation, the built-in internal reverse circulation flow ports continuously provide full wellbore return fluid passage during the whole construction process to realize well cleaning circulation; after the perforation construction work is fully completed, lift the coiled tubing string together with the integrated jetting sub out of the wellbore to finish operation, no additional complex auxiliary operation steps such as separate ball dropping or plug setting are needed to shorten wellsite operation time and reduce human error risks.
Low Routine Maintenance Design: The integral cylindrical alloy steel tool body eliminates vulnerable split assembly movable wear parts; after each wellhead coiled tubing sand jet perforation construction operation, only simple surface circulating fluid debris cleaning and tungsten carbide nozzle inner wall erosion wear inspection are required, no complex disassembly, internal nozzle component replacement or spring preload adjustment maintenance procedures, greatly reducing daily maintenance labor and spare parts inventory cost.
