| Abstract: | Jing'an oilfield of Changqing oilfield is characterized by low permeability, severe heterogeneity, high chlorite content and poor acidizing effect. According to these characteristics, an IPPA acid system with good retarding property is developed in thisstudy, which can solve the problems of poor acidizing effect in Changqing oilfield. The result shows that the system, with functions ofenhancing acid retardance and inhibiting secondary precipitation, can improve acidizing effect. Retarded deep-acidizing for ... |
