Selection method of froth generating solution with minimal harmful environment effect and the best technological characteristics was considered. Determining of gas-liquid mixtures characteristics research was described. Suggested solution allows to select most suitable gas-fluid mixtures for hydrogeological well-boring.

An analysis of oil and gas deposits with zones of abnormally low formation pressure of a productive layer has been completed. Investigation of technological properties of liquid-gas mixtures is conducted. Lathering ability of the fluids, kinetics of liquid-gas mixtures’ destructions and their rheological properties are investigated. Formulations of fluids for make-up liquid-gas mixtures according to shown requirements are offered.
