Crawler refers to a class of underground conveying equipment fit for use in horizontal wells and those with a large inclination. It can be self-powered to carry a piece of down-hole equipment to the target location in case that the load ceases to move downwards due to the action of gravity.
• A hydraulic crawler is comprised mainly of a on-ground control system as well as a down-hole instrument string and control system.
• Fitted with a on-ground control system that features a three-tiered intelligent collaborative architecture to offer an industrial-grade solution, which integrates real-time measurement, high-precision control and data management, demonstrating a high-degree integration of modernized industrial automation with advanced measurement and control technologies.
• Equipped with a downhole system that adopts a sophisticated modular series layout to ensure a smooth, coordinated operation between mechanical connections, electrical transmissions and hydraulic works in high-pressure, high-temperature, confined spaces, while a high degree of both flexibility and reliability is required.
