The working process of ST90 Coiled Tubing
At present, the oil and gas field has entered the middle and late stage of development. With the intensification of resource exploration, reducing operating costs and avoiding operating risks have become the primary considerations for oil and gas field development. Deepening sidetracking in old wells to increase potential efficiency and increase production from difficult-to-recover reserves, The development of horizontal wells and shallow oil and natural gas and coalbed methane resources is the most effective way to improve oil and gas recovery. For this kind of operation, and can effectively reduce the cost and damage to the operating environment, it is considered to be a revolutionary new technology in the workover operation method of oil and gas wells in the 21st century. It is foreseeable that the ST90 Coiled Tubing technology will surely become one of the leading technologies in the workover industry in the future. In particular, it has broad application prospects in small wellbore, old wellbore re-entry and pressure-bearing operations, providing a broad development space for ST90 Coiled Tubing technology.
At present, the ST90 Coiled Tubing operation involves almost all conventional drill pipe and tubing operations. It has been widely used in oil and gas field workover, acidizing, fracturing, perforating, logging, completion, drilling, and surface oil and gas pipelines, such as unblocking and dredging, especially for pressure-bearing operations, horizontal wells and high-deviation It is known as "universal operation" equipment for operations such as well logging, perforation, and completion. Compared with using conventional tubing operations, ST90 Coiled Tubing has the advantages of saving operation time, reducing formation damage, and operating safely and reliably. , playing an increasingly important role in oil and gas exploration and development.
