Abstract:

Some methods for measuring the properties of foaming agents at home and abroad are studied experimenthlly in this paper. On the basis of a large number of experiments, their advantages and disadvantages are analyzed and compared. It is suggested that the gas flow method is taken as the dominant one and Ross-Miles method as the second to evaluate foaming agents for removing water from gas well.
