Abstract

In recent years, the use of drilling emulsion inhibition fluids in wells has increased. These make it possible to maximally preserve the reservoir properties of the formation zone at the bottom of the wellbore, prevent jamming and sticking of the tool used, ensure the stability of the wellbore and the removal of cuttings to the surface, as well as provide high lubricity, which increases the technical and economic indicators for the construction of horizontal wells. In this work, experimental studies were carried out, which also supported the choice of the optimal formulation of emulsion drilling mud with the addition of Devon-2L lubricating reagent in order to improve the tribotechnical properties.

Key words:

drill pipe stiking, rheological properties, lubricant, mathematical model, optimal formulations of drilling fluids
