Abstract

The article deals with the contact of cement stone with the casing string, which are used in drilling hydrocarbon-based solutions, as well as the influence of some buffer fluids on the quality of wells and the choice of their components. To study this issue, experimental studies were carried out, the schemes of which are described in this paper. The aim of the research was to assess the effect of hydrocarbon solution on the quality of adhesion and washing capacity of the buffer liquids. The results of the study showed how the quality of adhesion changes, and revealed the most effective buffer fluid.

Key words:

the buffer liquid; cleaning power; hydrocarbon based muds (OBM); adhesion; surface -active substances (surfactants); hydrocarbon layer.
