摘要
确定的注聚井解堵剂主要由5%的裂解剂、3.50mol亚硝酸钠和3.30mol氯化铵水溶液作自生气体增能扩散剂,对于不同渗透率的岩心经过聚合物堵塞,解堵剂对渗透率恢复程度大于80%。解堵后注聚井注入压力下降1.7MPa,注入量增加52m3。
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 m^3.
