| Abstract: | Based on the acidizing principle of variable-viscosity acid,a acid blocking agent(DQ-3) was prepared with acid densifier as major raw materials,and with crosslinker and inhibitor as additives,to achieve combination of near-welibore unblocking and far-welibore blocking.The formula of acid blocking agent(DQ-3) is optimized:10%HC1,0.7%densifier, 0.4%crosslinker and 0.05%inhibitor.Various performances of DQ-3 were evaluated by gel test(bottle test method) and core flow test.The results show that when residual a... |
