Abstract
The invention provides a solid propellant for oilfield fracturing. The solid propellant uses an epoxy resin as an adhesive and comprises 7 to 21% of a bisphenol A diglycidyl ether type epoxy resin, 4 to 15% of a curing agent, 60 to 85% of an oxidizing agent, 0 to 20% of a cooling agent and 0 to 1% of a curing accelerator. The solid propellant provided by the invention has good corrosion resistance; a phenyl ring in the structure of the solid propellant enables the solid propellant to have good heat resistance and rigidity; meanwhile, through addition of the acid anhydride curing agent with a rigid structure, heat resistance of a curing system is further improved. The invention has the following advantages: the solid propellant has good heat resistance and resistance to a high temperature of 200 DEG C for 48 h, is non-combustible and non-explosive and completely meets requirements on usage in a deep well oilfield; a formula for the solid propellant contains a few components, a technology is simple and practicable, a production process is stable and produces a product with reliable quality, and compatibility of the components in the formula is good, which enables no chemical action occurs during long-term storage of the solid propellant and under the conditions of high temperature and high pressure; raw materials are widely available and cheap, so production cost is low.
