Annotation:
The development and implementation of water-based drilling fluids technologies disposal is a main concern for most subsoil assets users. The article presents the results of theoretical and experimental studies on the development of drilling fluids conservation technology based on polysaccharides using a complex of bactericidal reagents. The analysis of the existing technologies for drilling fluids recycling and techniques of increasing the microbiological stability of polymer reagents is given. The results of comparative studies on microbial contamination (by total microbial number) of drilling fluids treated and non-treated according to the developed conservation technology are analyzed. The most promising conservation technology application is reuse of expensive inhibited water-based drilling fluids for multiple and conveyor drilling.
