Claim 3:
4. The application according to claim 3, wherein the application comprises following steps:
step 1, pumping the liquid explosive for the in-situ explosive fracturing in the low-permeability oilfields into formations, and mixing and shearing crude oils on walls with the liquid explosive for the in-situ explosive fracturing in the low-permeability oilfields to obtain a mixed explosive; and
step 2, pressing a booster explosive into a vertical wellbore for exploitation, so that the booster explosive is connected with the mixed explosive in the formations, and igniting, wherein explosion in the wellbore is transferred into the formations and the mixed explosive in the formations explodes and releases high-temperature and high-pressure gases to fracture reservoirs.
