In oilfield operations, continuous tubing flushing and descaling technology has long been a critical process, effectively addressing tubing scale buildup and ensuring efficient well performance. However, traditional flushing and descaling operations often rely on crane equipment, which not only increases costs but also poses safety risks. Recently, our company successfully implemented a crane-free operation in a continuous tubing flushing and descaling project and secured a national patent for this innovative technology, setting a new benchmark for industry advancement.

I. Technological Breakthrough: The Realization of Crane-Free Operations Conventional continuous tubing flushing and descaling operations require crane equipment to lower the tubing into the well, a process that is time-consuming, labor-intensive, and demands significant space and site conditions. To address this challenge, our technical team, after years of R&D and field testing, developed a crane-free continuous tubing flushing and descaling system. By optimizing equipment structure and workflow, along with a self-developed hydraulic drive system and flexible guiding device, this technology enables rapid tubing deployment and retrieval without relying on cranes.

The application of this technology has significantly reduced costs and improved efficiency. Field operations have demonstrated its advantages: a 30% reduction in operation time, a 50% decrease in labor costs, and the elimination of safety risks associated with crane operations, earning high praise from clients.

II. Innovation Highlights: Technical Advantages and Patent Achievements The core innovations of the crane-free continuous tubing flushing and descaling technology lie in its hydraulic drive system and flexible guiding device. The hydraulic system automatically adjusts tubing speed and force based on downhole conditions, ensuring smooth and safe operations, while the guiding mechanism minimizes bending and friction at the wellhead, extending equipment lifespan.

Additional advantages include: Eco-Friendly & Efficient: High-pressure flushing thoroughly removes scale, reducing chemical usage and environmental impact. High Adaptability: Suitable for various well types, including horizontal, deviated, and complex wells, broadening its application scope. User-Friendly Operation: Integrated design and an intuitive interface lower technical barriers for field personnel. With its outstanding technical merits and originality, this technology has been granted a national patent, marking another milestone in our oilfield solutions portfolio.

III. Application prospects: promote the upgrading of industry technology The successful application of hoisting-free coiled tubing flushing and scaling technology not only won the market opportunity for our company, but also provided new ideas for the technological upgrading of the industry. At present, this technology has been popularized and applied in many oilfield construction sites, and has achieved significant economic and social benefits.

In the future, our company will continue to increase R&D investment, further optimize and improve the hoisting-free technology, and explore its application possibilities in other oilfield operation scenarios. We believe that the promotion of this technology will inject new impetus into the efficient, intelligent and green development of oilfield operations, and contribute to the high-quality development of the industry.
