Product Overview
The Hydraulic Extended Tool hydraulic pulse vibration shock exciter is a special hydraulic vibration shock generation tool developed for coiled tubing extended-reach horizontal well friction drag reduction and bridge plug milling grinding remedial workover operations.
The hydraulic extended tool relies on circulating well fluid to drive the internal pulse vibration mechanism to generate continuous periodic hydraulic vibration and pressure shock pulses; the periodic shock pulses can drastically lower frictional drag resistance between coiled tubing string and wellbore inner wall, effectively increasing the maximum running penetration depth of coiled tubing in long horizontal displacement wells. When matched and combined with positive displacement motors (PDM / screw drilling motors), the periodic vibration shock pulse output of the tool can greatly improve the effective weight load transfer that can be applied to the drill bit at the end of the tubing string, providing stable sufficient cutting weight for bridge plug milling grinding construction operations. Each specification supports a wide universal applicable circulation flow rate range of 90 to 400 liters per minute, with strong adaptability to different coiled tubing circulation pump displacement construction demands.
The Hydraulic Extended Tool 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 run the hydraulic extended tool down along the tubing inner wall to the target horizontal well construction section, start the surface circulation pump to drive the internal pulse vibration mechanism to generate continuous periodic hydraulic vibration shock pulses, realizing two-in-one functions of tubing-wall friction drag reduction and drill bit effective weight transfer boosting for bridge plug milling work, no additional auxiliary operation steps such as drop ball delivery or shear pin impact jarring are needed, shortening wellsite operation time and reducing human error risks.
The standardized product lineup covers outer diameter sizes ranging from 2-1/8" to 3-1/8", with complete outer diameter specification series to match different tubing inner diameter constraint conditions and different horizontal well remedial workover construction demands. All standard specifications adopt standard working condition configuration; custom outer diameter, applicable flow rate range and base material corrosion resistance grade customization are available upon customer technical drawing submission.

Full Outer Diameter Size Range Coverage: The applicable outer diameter size range of the hydraulic pulse vibration shock exciter covers 2-1/8" to 3-1/8", with complete outer diameter specification series to match different tubing inner diameter constraint conditions and different horizontal well remedial workover construction demands.
Ultra-Simplified Wellsite Operation Logic: The hydraulic extended tool has no complex internal movable friction components, spring energy storage assemblies or differential pressure release mechanisms, the operation flow is highly streamlined: only need to run the hydraulic extended tool down along the tubing inner wall to the target horizontal well construction section, start the surface circulation pump to drive the internal pulse vibration mechanism to generate continuous periodic hydraulic vibration shock pulses, realizing two-in-one functions of tubing-wall friction drag reduction and drill bit effective weight transfer boosting for bridge plug milling work, no complex auxiliary operation steps such as drop ball delivery or shear pin impact jarring 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 horizontal well remedial workover operation, only simple surface circulating fluid debris cleaning and internal pulse vibration mechanism wear inspection are required, no complex disassembly, internal vibration pulse generation component replacement or spring preload adjustment maintenance procedures, greatly reducing daily maintenance labor and spare parts inventory cost.
