Thickener products

The usage concentration is low and it is easy to prepare on site. It can achieve a good thickening effect even with a small dosage.

It is salt-resistant and high-temperature-resistant. Since this product is a cationic polymer, it can prevent clay swelling and particle migration. It has good fluid-discharging performance.

It has excellent compatibility with other additives used in acid solutions, such as corrosion inhibitors, iron-ion stabilizers, and flow-back aids.

It can effectively reduce the acid-rock reaction rate and the acid-fluid filtration rate, and expand the treatment radius of the acid fluid.

The JF series of salt resistance thickener product(High viscosity sand carrying) incorporate sulfonic acid groups that are insensitive to salt and high temperatures, along with groups featuring hydrophobic functions. This enables the viscosity retention rate in high-salinity brine and wastewater to be ≥ 70%, thus effectively resolving the predicament where conventional products almost lose their viscosity in such media. Moreover, this thickener product is easy to prepare and ensures safe and reliable construction.

The construction of the compound system of thickener product and drag reducer requires selecting appropriate types of thickener product and drag reducers according to the characteristics of the target formation, construction process requirements, and fracturing fluid performance needs, and determining the optimal compounding ratio and process conditions. 

Currently, the commonly used methods for constructing compound systems mainly include the following: 

Compound method based on molecular structure design: Through molecular structure design, the thickening function and drag-reducing function are integrated into the same polymer molecule to achieve "one agent with multiple functions". For example, by introducing rigid functional monomers and highly polar hydrophilic monomers into the polymer molecular chain, a multifunctional polymer with both high efficiency thickener product and drag reducing properties can be prepared. 

Compound method based on solution property regulation: By regulating parameters such as the pH value, ionic strength, and temperature of the solution, the interaction between the thickener and the drag reducer is optimized, and the comprehensive performance of the compound system is improved. For example, adding an appropriate amount of salt to a hydrophobic associating polymer solution can compress the double electric layer of the polymer molecular chain, promote hydrophobic association, and enhance the thickening and drag reducing effects. 

Compound method based on functional complementarity: According to the functional characteristics of thickener product and drag reducers, complementary components are selected for compounding to achieve synergistic enhancement of performance. For example, compounding a hydrophobic associating polymer with excellent thickening performance with a linear polymer with high efficiency drag reducing performance can obtain a fracturing fluid system with both high viscosity and low resistance. 

Compound method based on responsive design: By introducing environmentally responsive groups, the compound system exhibits different performances under different conditions, realizing intelligent regulation. For example, designing a compound system sensitive to temperature, pH value, or shear rate can automatically adjust the viscosity and drag reducing performance at different construction stages to meet the construction requirements of different stages.
