| Abstract: | Considering the influences of induced stress and initial cracks on the refracture of injection - production, an induced model was built around in accordance with the principle of superposition of potential wells refracturing pore pressure. A model of artificial cracks was established by introducing a fluid impact factor coefticient, which prorides a reliable basis for theoretical calculations. |
