What is the magical effect of fracturing liquid nitrogen?

Fracking liquid nitrogen vehicles are assisted with liquid nitrogen during fracturing in the oil field, so that the formation with insufficient pressure will release the fracturing fluid as soon as possible. The fracturing liquid nitrogen vehicle is a fracturing and assisting function and a German-specific vehicle, in which liquid nitrogen can be modulated on site.

What is the main working process of the fracturing liquid nitrogen vehicle? The liquid nitrogen vehicle is mainly used for hydraulic nitrogen cracking equipment to complete the liquid nitrogen nitrogen fracturing and fracturing work, and is used for all kinds of large-scale nitrogen replacement, airtightness, and pressure test construction. This process is particularly used in gas lifts for gas lifts. It is well known that nitrogen is an inert gas that is only slightly soluble in formation fluids and does not cause damage to the reservoir; this characteristic makes liquid nitrogen less likely to react with other substances such as reservoirs when it enters the formation to be fractured, and the possibility of explosion is reduced. , improve the safety performance of its use. The liquid nitrogen concomitant injection technology has a low fracturing fluid fluid loss, a high rate of return flow into the well, and can effectively discharge a large amount of crude oil, improving the production efficiency. The fracturing fluid has small surface tension and low density. After the pressure is raised, the flow rate of the liquid is increased. In the fracturing process, liquid nitrogen can increase the elasticity of the fracturing fluid and effectively improve the fracturing fluid's sand suspension performance. Most of the air is nitrogen and raw materials are readily available. The liquid nitrogen vehicle uses a direct-fired evaporation system to convert high-pressure liquid nitrogen into high pressure nitrogen gas for injection into oil, gas wells or other devices for construction purposes. The fracturing liquid nitrogen vehicles currently produced mainly include diesel power units, direct-fired liquid nitrogen evaporators, torque converters, gear boxes, reciprocating three-cylinder liquid nitrogen pumps, centrifugal infusion pumps, and various operation control switches. During normal operation, liquid nitrogen flows from the storage tank through the centrifugal infusion pump into the three-cylinder pump and is pressurized by the reciprocating piston to the working pressure. Then, the high-pressure liquid nitrogen flows into the human evaporator and absorbs enough heat from the evaporator to change it. For high pressure gas, the temperature rises to 15°C to 21°C and the discharge valve exits at a displacement of up to 800,000 standard cubic feet per hour. The entire process was completed. In oil extraction, liquid nitrogen is pumped through a centrifugal infusion pump and injected into the oil layer to cause fractures in the rock formation. Under strong pressure, crude oil is discharged.

In addition to the oil extraction industry, what can be used for fracturing liquid nitrogen vehicles? It is also useful in traffic, mainly in tunnel and bridge technology, by fracturing liquid nitrogen technology to remove complex geological conditions from your water and other substances that have caused address collapse. Improve the safety of the building. With the development of small fracturing liquid nitrogen vehicles, some privately operated coal mines, gold ore mines, etc. are used.

At present, the use of fracturing liquid nitrogen vehicles is continuously expanding. With the gradual depletion of resources in the mainland, people are turning to the exploitation of the oceans with abundant resource reserves. The geological conditions of the seabed are more complicated, and the rock layers are of different hardness and are often rich in oil and gas. And other resources, fracturing liquid nitrogen vehicles can play a more professional advantage in this regard.

I have no people, I have excellent people, China's professional car manufacturing needs further improvement, so as to continue to adapt to changing international competition and stand up.
