Hydraulic fracturing has been widely used in oil fields. For conventional hydraulic fracturing, it is hard to separate intervals in multi-layered formation. Hydra-jet fracturing technique can avoid this problem. The boosting pressure in cavity behind the casing is a key factor in hydra-jet fracturing process, making the fracture initiation successful. However, there is little research about the pressure field in cavity. This paper aims to establish a mathematical model for predicting boosting pressure in the cavity under different scenarios and predict the fracture geometry.
