FIELD: oil and gas production industry. SUBSTANCE: this relates to elimination of drilling mud absorption in drilling wells. Improved reliability and efficiency of operation are achieved by successive injection into well of buffer liquid, polymerizing liquid, separating liquid, initiator of polymerization, and pressing liquid. Used as polymerizing liquid is furfuryl alcohol, and used as initiator of polymerization is concentrated nitric acid. EFFECT: high efficiency.
