Hydraulic Fracturing Chemicals and Fluid Technologies
In today's stage of continuous growth in energy demand, hydraulic fracturing technology, as a key oil and gas extraction method, plays a vital role. Hydraulic fracturing chemicals and fluid theory are the core elements of this extraction link, providing a powerful application for efficient and sustainable energy production.
There are many types of hydraulic fracturing chemicals, each with its own unique role. The first is the resistance agent, which can significantly reduce the flow resistance of equipment and formation fracturing fluid. In the high-pressure introduction link, the liquid must reach the target formation quickly and smoothly. The appearance of the resistance agent is like "changing a pair of roller skates", which greatly improves the introduction efficiency and reduces energy loss. This can not only reduce the cost of extraction, but also make the fracturing work more efficient.
Cross-linking agent is also one of the indispensable compounds. It can make the fracturing fluid form a suspicious gel structure with a certain strength and reliability. When the fracturing fluid enters the formation, the cross-linking agent promotes the connection of liquid molecules to form a three-dimensional network structure. This type of suspicious gel fracturing fluid can better bring the proppant to the depth of the gap, ensure the extension of the gap in the extraction link, and create a good channel for the successful discharge of gas.
The debonding agent plays a key role after the fracturing operation. It can restore the cross-linked gel fracturing fluid to a liquid state that is easy to flow and easy to discharge from the formation. If the fracturing fluid cannot be debonded and discharged in time, it will cause damage to the formation and endanger the subsequent extraction of gas. The precise action time and quality control of the debonding agent are crucial to protecting the formation and improving the recovery rate.
After talking about chemical agents, let's take a look at hydraulic fracturing fluid technology. The selection and design of fracturing fluid is directly related to the fracturing effect. Common fracturing fluids include water-based fracturing fluids, oil-based fracturing fluids, and foam fracturing fluids.
Due to its low cost and wide sources, water-based fracturing fluids have become the most widely used type of fracturing fluid. However, it also has some limitations, such as clay swelling and other damage to certain formations. In order to overcome various problems, the R&D department continues to improve water-based fracturing fluids and optimize their performance by adding various additives.
Oil-based fracturing fluids are suitable for some unique formations with high water sensitivity. It has good lubricity and anti-clay swelling level, but it is expensive and has certain environmental risks.
Foam fracturing fluid is a relatively new fracturing fluid, which is a mixture of gas (such as nitrogen or carbon dioxide) and liquid. Foam fracturing fluid has the characteristics of high density and high sand level, and is particularly suitable for low-pressure formations. In the fracturing process, the presence of foam can reduce damage to the formation. After breaking the gel, the gas can escape quickly, which is convenient for the discharge of the fracturing fluid.
With the continuous advancement of technology, water fracturing compounds and liquid technology are also keeping pace with the times. On the one hand, the R&D department is committed to developing more environmentally friendly and more effective compounds to reduce pollution; on the other hand, based on the in-depth research and improvement of liquid technology, the gas acquisition rate of fracturing performance is continuously improved.
In short, water fracturing chemicals and liquid theory are a field of continuous development and optimization. They play an irreplaceable role in promoting the development of the oil and gas extraction industry and ensuring global energy supply. It is necessary to continuously invest in R&D forces and explore new technologies and new materials to achieve energy supply, complete high-quality development goals, and provide stable power for the progress of people's society.
