【 摘 要 】

This research describes the application of Kirek Lake sapropel as a drilling fluid in dispersed phase which could replace traditionally used clay powders in drilling fluids. Sapropel is century-old bed silt of freshwater lakes of more than 12 000 years, i.e. Holocene. It consists of natural organic and inorganic substances and chemically is a complex multicomponent biogenic genesis system. Humic complexes and wulfonic acids, polysaccharides, carbonic and protein polymers comprise sapropel suspension texture. This article introduces formulations and laboratory research of sapropel suspensions and thermal activation.
