Special vehicles are very common nowadays. A lot of models such as road sweepers, sprinklers, and aerial platforms have all been heard of, and they probably know their purpose. But when it comes to coiled tubing, surely everyone is unheard of, and you never saw it. Some people may ask if it belongs to a special car. Yes, it is also classified as a special car. I believe we must also really want to understand this model, this article will be detailed in small series for everyone to introduce the function and characteristics of coiled tubing.
Let's talk about the historical development prospects of the coiled tubing truck:
Coiled tubing trucks have been used abroad for 25 years. Many foreign manufacturers are producing such models, but there are very few manufacturers in China. Jianghan Machinery Research Institute and Petroleum University of China have all researched the coiled tubing operation vehicle and made certain progress. However, it is still unable to meet market demand due to process limitations.
The use of coiled tubing trucks in oilfield operations in the country is becoming increasingly widespread. Due to the complex structure and high degree of automation of such vehicles, most of China's operating vehicles rely on foreign imports. The coiled tubing truck has a good application prospect, and it has been designed to develop domestic products.
Coiled tub truck features:
The coiled tubing truck is a movable hydraulically driven coiled tubing starting and transporting equipment. Its most basic function is to start a coiled tubing string in a well when performing a coiled tubing operation. After the operation, a coiled tubing is taken out and wound on a reel for transport.
The powerful operation function enables the coiled tubing truck to perform various complicated operations. It is the best tool to replace the manual completion of the downhole operation. Coiled tubing trucks are widely used in various stages of drilling and production. Sand flushing and simple workover operations are its unique skills. In addition to these coiled tubing trucks, it is also possible to complete a series of tasks such as cementing, salvaging, logging, reaming, and descaling.
Coiled tub truck structure:
The use of functions is complex and the structure is more complicated. Several of the most basic functional devices include coiled tubing injection heads, coiled tubing rollers, power systems, consoles, and wellhead blowout preventer sets...
First, the injection head is mainly used to overcome the buoyancy and friction force of the tubing in the effective wellbore to push the tubing into the well, control the downhole speed of the coiled tubing in different well conditions, suspend the tubing and speed up the tubing from the well.
Second, the drum is composed of the core and side flanges by the core and edge flange, corresponding to the diameter of 1 inch and 11/4 inch coiled tubing, the core diameter is 1.524 ~ 1.828 meters, the flange diameter is 2.743 In meters, the coiled lengths are 7,925 and 6,706 meters respectively, and the coiling capacity of other sizes of tubing depends on the diameter of the core.
Third, the hydraulic power system is the head of the entire vehicle, control the operation of all components of the operating machine, all operations must rely on it to complete.
Fourth, the console to provide staff to facilitate the operation, the console is equipped with all the instruments, switches, etc., to monitor and control the operation of all devices coiled tubing operations.
Editor's Note: Today in the 21st century, the state is strongly advocating the replacement of manual operations with mechanized operations. Some tasks that cannot be done manually are very convenient for mechanical replacement. The coiled tubing truck is the best mechanical tool to replace difficult manual operations.
Seamless carbon steel pipes are made of steel ingots or solid billets through perforation to make capillaries, which are then hot-rolled, cold-rolled or cold-drawn. The raw material of carbon Steel Pipe is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. Furnace temperature control is a critical issue. After the round tube blank is released from the furnace, it is pierced through a pressure punching machine. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls.
1. Seamless steel pipe for structure (GBT8162-2008). Mainly used for general structure and mechanical structure. Its representative material (brand): carbon steel, 20, 45 steel; alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.
2. Seamless steel pipes for conveying fluids (GBT8163-2008). It is mainly used for conveying Fluid Steel Pipe in engineering and large-scale equipment. The representative material (grade) is 20, Q345, etc.
3. Seamless steel pipes for low and medium pressure boilers (GB3087-2008) are used to manufacture various structures of low and medium pressure boiler superheated steam pipes, boiling water pipes and superheated steam pipes, large smoke pipes, small smoke pipes and arch bricks for locomotive boilers Hot-rolled and cold-drawn (rolled) seamless steel pipes of high-quality carbon structural steel for pipes. The representative material is 10, 20 steel.
