| Abstract: | The determined polymer injection well blocking agent was composed of the breaker(5 %),NaNO2(3.50 mol)and NH4Cl(3.30 mol)solution to be the self-generating gas energization diffusant.After the polymer blocking to the different permeability corn,the permeability recovery degree of the blocking agent is more than 80 %.After broken down,the injection pressure of the injection wells decreased 1.7 MPa and the injection volume increased 52 m3. |
