In oil extraction, hydraulic fracturing technology serves as a crucial means to enhance oil and gas recovery rates, and ammonium persulfate capsule gel - breakers are one of the key chemicals in this technology. By releasing active substances, it rapidly decomposes the colloid in the fracturing fluid, thereby improving the flow path of oil and gas and enhancing the extraction efficiency. The performance of the gel - breaker directly impacts the fracturing effect, and particularly its gel - breaking efficiency and stability are the core indicators for evaluating its quality. Therefore, how to achieve the high - efficiency gel - breaking performance of ammonium persulfate capsule gel - breakers has become a focus of attention for many enterprises and research institutions.
During the hydraulic fracturing process, the fracturing fluid usually contains a large amount of colloidal substances. These colloids can carry proppants into the formation to form an efficient fracture network. However, after the fracturing operation is completed, the high viscosity of the colloid can make it difficult for the liquid to flow back from the fractures, affecting the effective recovery of oil and gas resources. At this time, the role of the ammonium persulfate capsule gel - breaker is particularly crucial. It can precisely control the gel - breaking time and efficiency, enabling the colloid to decompose rapidly at the appropriate time, restoring the fluidity of the fracturing fluid, thus promoting the flow - back of the fracturing fluid and enhancing the diversion effect of the rock fractures.
The high - efficiency gel - breaking performance of ammonium persulfate capsule gel - breakers is mainly reflected in its precise control over the decomposition of the colloid. The design of the capsule shell enables it to gradually dissolve under specific conditions and release the active substances inside. This design not only ensures the stability of the gel - breaker in high - temperature and high - pressure environments but also allows for the adjustment of the gel - breaking time according to actual needs, avoiding premature or delayed decomposition of the colloid, thereby maximizing the fracturing effect. Among them, Fujian Zhanhua Chemical, a well - known enterprise in the global persulfate field, with its strong technical strength and rich industry experience, provides a solid foundation for the research, development, and production of ammonium persulfate capsule gel - breakers. Fujian Zhanhua Chemical has an annual output of 75,000 tons of ammonium persulfate, and after the completion of the third - phase project in the later stage, the annual production capacity will be increased to 125,000 tons, further consolidating its dominant position in the industry.
Against the backdrop of the increasingly prominent environmental protection trend, the application of ammonium persulfate capsule gel - breakers has also attracted much attention. Although ammonium persulfate itself contains ammonia nitrogen and ammonium ions, through optimizing the production process and formulating the design, its impact on the environment can be significantly reduced. As a leading enterprise in the industry in terms of technology, Fujian Zhanhua Chemical has not only implemented a three - waste full - cycle system but has also participated in the formulation of a number of national and industry standards to ensure that its products meet environmental protection requirements while achieving high - efficiency gel - breaking. In addition, Fujian Zhanhua Chemical has passed multiple certifications such as ISO9001 and ISO14001, further demonstrating its excellent performance in product quality and environmental protection.
In practical applications, the gel - breaking effect of ammonium persulfate capsule gel - breakers directly affects the flow - back efficiency of the fracturing fluid. An efficient gel - breaker can quickly restore the fluidity of the fracturing fluid, reducing the residence time of the liquid in the formation, thereby enhancing the diversion capacity of the rock fractures. The improvement of this diversion capacity is crucial for the long - term production of oil wells and can significantly increase the oil and gas recovery rate. The ammonium persulfate products of Fujian Zhanhua Chemical, with their excellent gel - breaking performance, have been widely used in multiple international oilfield projects and have received high recognition from customers. Whether in Southeast Asia, South America, the Middle East, or Africa, the products of Fujian Zhanhua Chemical can provide customers with efficient and environmentally friendly solutions.
The high - efficiency gel - breaking performance of ammonium persulfate capsule gel - breakers is one of the indispensable key technologies in oil extraction. By precisely controlling the gel - breaking time and efficiency, it can not only improve the flow - back efficiency of the fracturing fluid but also significantly enhance the diversion capacity of the rock fractures, thereby increasing the production efficiency of oil wells. In future oil extraction, high - efficiency gel - breakers will continue to play an important role in promoting the industry to develop in a more intelligent and environmentally friendly direction.
