In terms of application, since the middle and late 1990s, coiled tubing technology has gradually expanded from conventional operations such as workover to drilling operations. In recent years, coiled tubing drilling and fracturing technology have become the two fastest developing technologies. As one of the emerging drilling technologies vigorously researched and developed abroad, coiled tubing drilling is mainly used to drill new wells and sidetrack old wells. This drilling technology is mainly developed to adapt to multi branch wells, old wells re drilling (including old wells deepening and sidetracking), tubing drilling, slim hole drilling and underbalanced pressure drilling. In addition to land, coiled tubing is also used for offshore operations - drilling on offshore platforms or floating production facilities without permanently installing drilling equipment, drilling rescue wells, and drilling in environmentally sensitive areas (reducing noise, site restrictions, preventing splash, and optical interference). Compared with conventional fracturing, coiled tubing fracturing technology is more suitable for the reconstruction of different types of oil and gas reservoirs. The coiled tubing equipment and reliability have become an effective means to reduce downhole operation risks and reduce operation failures.

Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.

It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow

drilling fluid to circulate and extraction to take place
