Study On Structures And Properties Of Low-Permeability Oil-Gas Reservoirs Frac Ball

Fracturing technology is the core technology to develop unconventional resources especially low and extra low-permeability gas reservoirs, but the quality of fracturing ball determine the technical success or failure. The high performance PEEK/Carbon Fiber (CF) composite was prepared by means of extrusion pelletization with the raw material of Carbon Fiber and pure PEEK, and the micro-morphology, thermal performance and mechanics property of the composite were studied using infrared spectrum analysis, SEM, TGA test and laboratory testing. The results indicated that the combination of CF and PEEK was tight, the thermal decomposition temperature is above 500 degrees C. when the mass fraction of CF was about 20%, and the tensile strength, shear strength and flexural strength of the composite were very good.
