Abstract Alkali/surfactant/polymer (ASP) flooding process is proven to be vitally effective for enhancing oil recovery (EOR) in the oil industry. However, foaming behavior is generated by the breakthrough of chemical agents in the produced liquid and is increasingly concerned as a terrible problem during production. A set of experiments was recently performed to investigate the effects of foaming properties of ASP flooding produced liquid. The factors affecting foaming capacity and foam stabilization were discussed, and the differences in foaming properties of produced liquid between strong base and weak base ASP flooding were firstly compared. The results indicated that in addition to temperature and pressure, the concentrations of chemical agents in the produced liquid were responsible for the foaming properties and foam stabilization. The foaming capacity could enhance 3∼7% at 45 °C compared with a lower temperature of 35 °C. The average comprehensive index of the foam could increase from 2.2×105 at 29 psi to 2.5×105 at 73 psi. The regularity of Plateau borders was highlighted at higher pH and surfactant concentration, and thus facilitated the foam stabilization. The liquid film thickened and its shape expanded to the state of maintaining foam stabilization with the increase of polymer concentration. Furthermore, the foaming behavior of produced liquid in strong base ASP flooding production is much more troublesome than that in weak base ASP flooding production. This study is significant in that it further supports the development of efficient treatment technology for produced liquid in oilfield.

Aiming at the production wells’ problem of stuck pump, blocking, pipeline corrosion and scaling in ASP flooding test area in Daqing oilfield Xingbei block, based on the actual situation the study system was defined, on the basis of laboratory experiment to simulate silica scale forming, and the forming process was observed, the silicon scale-forming regular after the formation of alkali corrosion was studied. The results showed that in the complex condition of ASP flooding system, silica scale forming was affected by variety of factors, the process was that monosilicic acid gets together to poly silicic acid, and then condensation polymerization and dehydration generate gel. In the process of polymerization, the silicic acid can polymerize alone or adhere to another pellet molecule, polymerization and dehydration generate to mixed scale.
