▎ 摘  要

NOVELTY - A temporarily blocking steering fracturing method involves using polyethylene glycol 200 and polyethylene glycol 400 mixed as a dispersed phase, mixing with nano silicondioxide, graphene and carbon nanotubes as a dispersion medium and magnetically combining with ultrasonic waves for uniform stirring to prepare a shear thickening liquid STF, setting packer cover the main section to be constructed, slowly transporting the STF liquid into the crack by the coiled tubing, pumping fracturing fluid into the well by the ground high-pressure pipeline after the STF liquid transported into the crack and pumping fracturing fluid into the pressure by stepwise adjustment to create a new complex fracture network in the formation. USE - Method for blocking steering fracturing temporarily. ADVANTAGE - The method enables blocking steering fracturing temporarily with greatly improving reservoir reforming effect.
