Thermal cracking effect of liquid nitrogen on shale and its application analysis in hydraulic fracturing

摘要:In order to investigate the effect of liquid nitrogen on thermal cracking of shale rocks, ultrasonic and permeability tests were performed on the shale rock samples before and after being soaked in liquid nitrogen. The cracking mechanism of liquid nitrogen and its influencing factors were analyzed. The advantages and prospects for liquid nitrogen to be used as a fracturing fluid in shale gas development were discussed. The experimental results indicate that obvious thermal cracks can be observed on the surface of the shale samples after the soaking in liquid nitrogen. The rapid cooling effect of liquid nitrogen can promote the growth of micro cracks inside the shale samples, resulting in the reduction of sound velocity and increase in permeability. The reduction in sound velocity was up to 10.43% while the increase in permeability can be over 177.27%.
