【Abstract】 Recently a new inhibited drilling fluid was developed, in which methylglucoside(MEG) is a primary component. The MEG drilling fluid has superior inhibition and formation damage prevention characteristic, and it is environmentally acceptable. In this paper, the investigation results of MEG drilling fluid were introduced, the MEG base fluid properties were evaluated and the experiments of semipermeable membrane existence around the wellbore were conducted.更多还原
