The Motor Head Assembly is a core component in the coiled tubing tool string, responsible for ensuring the normal operation of the tool string downhole. It integrates a double flapper check valve, a hydraulic disconnect tool, and a ball-activated circulating valve. While maintaining each function, it optimizes the tool's length, reduces connection time, and improves operational efficiency. It is suitable for coiled tubing operations of various sizes.
Product Features
Three Functions Integrated into One, Reducing Tool Installation Time: The modular design combines three core tools, lowering operational complexity and improving installation efficiency.
Compact Structure, Shorter Length: The optimized design shortens the tool's length, making it suitable for various sizes of coiled tubing and increasing downhole operational flexibility.
Simplified Operational Process, Improved Operational Reliability: Reduces connection points for individual tools, lowering the potential risk of leakage and enhancing overall reliability.
Strong Versatility: Suitable for a variety of well conditions and process requirements, and widely used in coiled tubing drilling, workover, and fishing operations.
