摘要

liquid for processing the borehole includes at least two phases, comprising a liquid phase and solid phase.solid phase is a powdered solid material bearing the coating of polymera product of the reaction between u043fu043eu043bu0438u044du0444u0438u0440u0430u043cu0438u043du043eu043c based on simple ether and u0434u0438u0430u043bu044cu0434u0435u0433u0438u0434u043du044bu043c u0441u0448u0438u0432u0430u0442u0435u043bu0435u043c.on the basis of simple ether is preferably u043fu043eu043bu0438u044du0444u0438u0440u0430u043cu0438u043du043eu043c u0434u0438u0430u043cu0438u043d and more preferably the compound acts in the role of u0437u0430u043cu0435u0434u043bu0438u0442u0435u043bu044f hydration glyn.u0434u0438u0430u043bu044cu0434u0435u0433u0438u0434u043du044bu0439 u0441u0448u0438u0432u0430u0442u0435u043bu044c reacts with u043fu043eu043bu0438u044du0444u0438u0440u0430u043cu0438u043du0430 derivative based on a simple air and forms a polymeric material forming a coating on a solid phase.the polymer is essentially u0441u043eu043bu044eu0431u0438u043bu0438u0437u0438u0440u0443u0435u0442u0441u044f when the value of ph of the working fluid has a value of less than about 7.
