| Abstract: | Acid damage is an effective technology to solve the problem of high fracturing pressure for the deep,tight,low-permeability sandstone reservoirs during fracturing or acid fracturing.A model for quantitatively predicting reservoir fracturing pressure of perforated wells with acid damage was established combining with damage mechanics,fracture mechanics and the finite element theory.The model considered the effects of rock mineral composition,acid type,acid amount and temperature on fracturing pressure.The mo... |
