Stainless steel coiled tubing (control line)(stainless steel coil)

 Stainless steel coiled tubing, also known as stainless steel flexible tubing or coil, the length of the general for hundreds of meters to thousands of meters, because of its large length, corrosion resistance, pressure resistance, high mechanical strength and other characteristics, it is widely used in oil, energy and other fields. For example, drilling, completion, testing, production, workover, gathering, pressure control and so on, with the development of coiled tubing machine and related equipment, its application is more extensive.

Oil well non-stop operation: pressure control equipment can make coiled tubing under pressure safe application; high-pressure pipeline: coiled tubing string for fluid circulation, in and out of the wellhead to provide a high-pressure channel. In addition, hydraulic tools can be operated by coiled tubing strings or downhole power can be provided by fluid pumps; Rigidity and strength: the rigidity and strength of the coiled tubing string allows tools and equipment, as well as the coiled tubing string itself, to be pushed into and pulled out of high-angle and horizontal wells; Install leads and piping: electrical leads or hydraulic piping can be installed in the coiled tubing string, ending at the coiled tubing reel, and job control and power functions can be installed between the downhole tool assembly and the ground equipment.

1, specification: 1/8, material: 316L, 316,304L, 30432122052507904L 825, etc. . It is mainly used for down-hole capillary pressure measurement, that is, temperature and pressure sensors (also called down-hole pressure gauge, commonly known as nitrogen barrel) and production string of oil and gas wells down-hole together with thousands of meters deep oil and gas zone, the 1/8” hydraulic control line (capillary) is then connected from the temperature and pressure sensors to the ground screen monitor, so that the downhole temperature and pressure can be transmitted to the ground through the capillary, and the screen of the surface monitor can read the instantaneous temperature and pressure at the downhole reservoir, thus realizing the real-time monitoring of downhole temperature and pressure.”. It can also be used for pressure control of surface relief valves and other surface valves, as well as various connecting pipelines for instrument control systems of large-scale drilling and production equipment in oil and gas fields. 2. Specification: 1/4, material: 316L, 316,304L, 304,32122052507904L 825, etc. .

This product is mainly used for... ... stainless steel coiled tubing initially won A Place to Stand, a Place to Grow in the market as an economic wellbore cleaning tool The economic income of Workover and completion operations accounts for more than 75% of the total income of coiled tubing operations In fact, coiled tubing has many advantages and application value, such as under-balanced operation with pressure, high efficiency, low formation damage and low cost Coiled tubing has been widely used in workover, drilling, completion and logging in oil and gas fields, playing an increasingly important role in exploration and development. Since 1990s, coiled tubing fracturing technology and coiled tubing drilling technology have been developed rapidly in technology and practical application . At present, according to incomplete statistics, there are about 30 coiled tubing machines imported from China, it is mainly distributed in Sichuan, Daqing, Truong Khanh, Shengli, North China, Central Plain, Jilin, Xinjiang, Liao River, Tuha, Sungai Besar, Henan and Karamay oilfields Since the introduction of coiled tubing, the total number of wells in Sichuan, Liao River and North China has exceeded 1000 wells The domestic coiled tubing machine is mainly used in the following aspects: Sand Washing, bridge plug drilling, gas lift, nitrogen injection, wax removal, fluid drainage, acid extrusion and coordination test. More is used sand plug, gas-lift drainage and wax removal, accounting for more than 95% . Coiled tubing (coiled tubing) is popular in our country.
