Product Overview
The Coiled Tubing Drill Motor positive displacement downhole drilling motor is a special positive displacement power generation tool developed for coiled tubing downhole milling, fishing and sidetrack drilling remedial workover operations.
This drill motor is specially customized for coiled tubing downhole milling and fishing construction operations, fully applicable to vertical straight hole and horizontal lateral section milling work; compared with traditional ordinary downhole motors, this coiled tubing drill motor can output far larger torque and higher power, which can significantly improve overall milling and drilling construction efficiency. Two independent bearing lubrication configuration options are reserved for users to choose: water-lubricated sliding bearing assembly or oil-sealed pressure bearing assembly, to adapt to different downhole well fluid medium construction environment demands. The rotor and stator assembly lobe number and multi-stage stacking quantity are fully customizable, realizing flexible matching of different torque output grades according to actual downhole construction torque load requirements, with prominent high-torque output performance.
The Coiled Tubing Drill Motor 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 drill motor to the bottom of the coiled tubing string, run the whole tool string down along the tubing inner wall to the target downhole milling or drilling construction section, start the surface circulation pump to drive the internal rotor/stator positive displacement rotation to generate high-torque power output, to complete plug milling, fish retrieval or sidetrack drilling construction 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 1-11/16" to 3-1/8", with complete outer diameter specification series to match different tubing inner diameter constraint conditions and various coiled tubing downhole milling, fishing and sidetrack drilling construction demands. All standard specifications adopt standard working condition configuration; custom outer diameter, rotor/stator lobe number, multi-stage stacking quantity and base material corrosion resistance grade customization are available upon customer technical drawing submission.
