FIELD: oil industry.
SUBSTANCE: group of inventions relates to oil and gas. Dispersion liquid for drilling is obtained by dispersing in water medium of polyoxalat as capable of hydrolysis of resin material. Procedure of extraction of minerals from the well, formed by drilling includes a step of inputting said dispersion of liquid in well under pressure for implementation of hydrolysis capable of hydrolysis of resin material in hot water with temperature not below 40 °C.
EFFECT: technical result – high ability to hydrolysis at low temperature of liquid reagent used at drilling and formation treatment.
