Under high temperature conditions, it can maintain the stability of its structure and properties, and can be used in high temperature operations such as deep well drilling. Due to the process of sulfonation, lignite molecules are added with sulfonic acid groups and other functional groups to strengthen the intermolecular force, making it difficult to decompose and metamorphose at high temperature, which is a guarantee for drilling fluid to maintain good rheology and filtration in high temperature environments.
The second is excellent filtration reduction. It can significantly reduce the amount of filtration of drilling fluid and prevent liquid phase from seeping into the formation. The hydrophilic group in its molecular structure can adsorb water molecules, form a hydrated film, increase the viscosity and shear force of drilling fluid, control fluid seepage, form a low penetration rate filter cake on the well wall, protect the well wall from stability, and avoid the collapse of the well wall due to excessive filtration.
The third has certain anti-collapse properties. It can be adsorbed on the rock surface of the well wall, improve the wettability of the rock surface, reduce the friction between rocks and capillary force, help maintain the mechanical balance of the well wall, and prevent the collapse of the well wall. And the filter cake formed on the well wall has toughness and compactness, and also has the function of protecting the well wall.
The fourth is good compatibility. It can be combined with a variety of drilling fluid treatment agents, such as viscosity reducers and tackifiers, etc., to complement each other and synergistically improve the performance of drilling fluids, so that they can meet the needs of drilling engineering under complex geological conditions.

What are the industries where Sulfonated Lignite is suitable?

Sulfonated lignite is used in a wide range of industries. In the oil drilling industry, it has great power. When drilling, the environment in the well is complex, and mud wall protection is required to prevent the well wall from collapsing, which is the most important thing. Sulfonated lignite can be integrated into the mud to improve its performance. Make the viscosity and shear force of the mud appropriate, not only to ensure the ability to carry drill cuttings, but also to allow the drill cuttings to settle stably when drilling is stopped, without hindering the drilling process. And it can enhance the filtration and control performance of the mud, so that the well wall forms a thin and tough mud cake, reducing liquid infiltration into the formation, maintaining the stability of the well wall, and ensuring the smooth drilling operation.
In the agricultural field, it also has its application. Soil structure and fertility are related to crop growth. Sulfonated lignite can be applied to the soil to improve the soil structure. It can enhance the formation of soil aggregates, make the soil porosity suitable, not only facilitate air circulation, but also facilitate root extension. And it can improve the ability of soil water retention and fertilizer retention, reduce nutrient loss, create a favorable foundation for crop growth, promote it to thrive and increase yield.
In the industrial wastewater treatment industry, sulfonated lignite also plays a role. Industrial wastewater is complex and often contains many pollutants. Sulfonated lignite has certain adsorption properties, which can absorb heavy metal ions and organic pollutants in wastewater. Through physical adsorption and chemical action, pollutants are enriched, so that wastewater water quality can be purified, reaching discharge standards, and making a lot of contributions to environmental protection. Therefore, sulfonated lignite is indispensable in industries such as oil drilling, agriculture, and industrial wastewater treatment, and plays a key role in the development of various industries.

What are the advantages of Sulfonated Lignite compared to other similar products?

First, it has excellent thermal stability. Sulfonated lignite is prepared by a unique process, and the molecular structure is stable. It can maintain good performance in harsh working conditions such as high temperature deep wells, while others may cause structural damage and performance decline due to high temperature. Like a strong ship of ancient times, it is made of good materials, and it can run stably despite rough seas. Sulfonated lignite is used in high temperature oil wells, just like this strong ship, escorting the stable performance of drilling fluids and making drilling operations smooth.
Second, it has strong fluid loss. Its molecules are rich in hydrophilic groups such as sulfonic acid groups, which can be adsorbed on the surface of clay particles to form a hydration film and hinder water loss. In complex geology, such as high-permeability formations, it can effectively reduce the amount of drilling fluid filtration and ensure the stability of the well wall. Other products may not be sufficient here, just like dams, sulfonated lignite can more closely block the penetration of water flow, and protect the well wall like an embankment.
Third, good compatibility. It can be soluble with a variety of drilling fluid treatment agents and synergistic. Whether it is polymers or cellulose, it can play a better role with it. This is like marching in ancient times. The various arms cooperate and sulfonated lignite can make each component of the drilling fluid system develop its strengths and improve the overall efficiency.
Fourth, it has a wide range of sources and good cost control. Lignite reserves are abundant, the preparation process of sulfonated lignite is mature, the raw materials are easy to obtain, and the cost can be reduced. Compared with similar products that rely on scarce raw materials or complex processes, the cost advantage is obvious. In large-scale drilling operations, it can save tariffs and promote efficiency. It is like a small effort to transfer thousands of catties, and the economic efficiency is excellent.

What is the production process of Sulfonated Lignite?

For sulfonated lignite, the method of preparation is as follows. First take lignite, which is produced in coal mines, which is soft and rich in humic acid. Break it up and make it into a fine powder with moderate particle size, which is convenient for subsequent reaction.
is to put lignite fine powder in the reaction kettle and add an appropriate amount of water to make it into a slurry. This is to make the reaction uniform. Add a sulfonating agent, such as sodium bisulfite or the like, and determine the amount of sulfonating agent according to the amount of lignite and the reaction requirements.
Add a sulfonating agent, raise the temperature of the reaction kettle to a suitable degree, often controlled at hundreds of degrees Celsius. At this temperature, stir it to make the lignite and the sulfonating agent fully react. It is also necessary to stir quickly. If it is too fast, it is easy to cause local overheating, and if it is too slow, the reaction will be uneven.
During the reaction, the pH value of the system must be measured and adjusted in time to ensure that the reaction is in the best acid-base environment. After several hours of reaction, when the various indicators of the system meet expectations, stop.
After that, the product obtained by the reaction is filtered to remove unwanted impurities and residues. The filtrate is a solution containing sulfonated lignite. After concentration and drying, the solid product of sulfonated lignite can be obtained. This product may be in powder form or granular form, depending on the drying method used.
The whole process requires following the procedures and controlling various parameters in order to obtain high-quality sulfonated lignite, which can be used in many fields such as drilling mud treatment. It also increases the fluid loss and thermal stability of the mud.
