The encapsulated gel breaker is a new type of gel breaker developed in recent years. The advanced coating technology is used to generate a protective layer on the common gel breaker, and the breaking speed is controllable. It is mainly used for flowback and gel breaking in water-based fracturing of oil wells, especially in the fracturing of medium and deep oil wells. The effective components of the encapsulated gel breaker are released by the formation pressure extrusion. It has the advantage of high effective components, release completely, low toxic, thorough breaking, easy flowback and less residue. Compared with the conventional common gel breaker, it’s obvious advantage is preventing the fracture fluid viscosity from descending rapidly and failure of work. However, if the capsule’s quality can’t meet the demand, the excessive rapid release speed of the breaker would lead to the fracture fluid viscosity premature descending and inducing the failure of work.
At present, the main gel breaker used in domestic oil fields is the encapsulated gel breaker with ammonium persulphate as the core, because ammonium persulphate crystal is easy to absorb moisture, our company has developed a set of re-granulation production processing technology. At present, the oil wells are mainly with high temperature and high pressure and high depth, and new requirements on high temperature resistance and good slow release performance of encapsulated gel breaker are constantly raised. The common encapsulated gel breaker has failed to meet the oilfield construction work requirements. With the help of domestic authoritative research and technology, our company successfully developed ammonium persulphate encapsulated gel breaker with high temperature resistance and slow release. At present, the gel breaking effect and temperature resistance time have basically reached the peak compared with same capsule core products in China.
The encapsulated gel breaker supplied by our company has good delayed release performance, which can keep the gel maintaining a high viscosity during fracturing construction for better fracture making and sand carrying. After construction, the fracturing fluid can be completely liquefaction and gel-breaking, which is conductive to backflow and reducing the construction risk, and reducing the damage of fracturing fluid to the supporting fracture conductivity.
Meanwhile, we use the original patented crystal regranulation technology to solve the problems of irregular crystal shape, poor coating rate and low compression performance, and use the patented formula in the granulation process to increase the hardness and temperature resistance, pressure resistance and shear resistance of the capsule core.
At present, we have three crystal re-granulation and shot blasting production lines, one granulation drying line, five fluidized bed coating production lines and a 5KG coating experiment line, with an annual capacity of 2000 tons.
