摘要：
The invention describes multiphase lubricant concentrates with enhanced properties to be used in acqueous working fluids from exploratory drilling of soil, containing liquid or solid organic constituents at room temperature with a lubricating effect (O-phase) in addition to emulsifiers which are finely dispersed in a closed aqueous phase (W-phase). The concentrates are characterized by the fact that the system consisting of an oil phase, a water phase and emulsifiers has a phase inversion temperature (PIT) above room temperature and is produced by heating the multiphase system to temperatures equal to/above the PIT and subsequently cooled to smaller PIT values. The invention also relates to the use of such multiphase lubricant concentrates as an additive to water based working fluids in the field of exploratory drilling of soil and further treatment of such drilling.
