Annotation:
One of the drilling waste types is used drilling fluids, the volume of which can reach several hundred cubic meters per well. Repeated use of drilling fluids for drilling several intervals or wells is one of the main ways to reduce the volume of his type of waste and reduce the cost of well drilling. The article shows the results of experimental studies of a complex of bactericides and the procedure for conservation technology using in field conditions. The requirements for the mud cleaning system for the possibility of mud reuse are given. The results of pilot field tests of biopolymer drilling mud conservation technology during the directional wells drilling at one of the Perm Region fields are presented. The volume of used drilling mud has been reduced by 23 %, drilling waste by 31 % due to the use of conservation technology, compared with the basic technology. The most promising application of conservation technology is for expensive highly inhibited water-based drilling fluids in the conditions of multiple and conveyor drilling.
