In the oil-based drilling fluid, a dispersed phase (water phase) is uniformly dispersed in a continuous phase (oil phase) mainly by virtue of an emulsifier, so that the stability of an oil-based drilling fluid system is directly determined by the quality of the performance of the emulsifier, and the rheological property and the filtration loss of the oil-based drilling fluid are also greatly influenced.
At present, the emulsifier for the domestic oil-based drilling fluid is mainly sorbitan fatty acid esters and polyamides. For example, chinese patent publication No. 104449598A discloses "a viscosifying emulsifier for oil-based drilling fluids and a method for preparing the same", which comprises sorbitan fatty acid esters, fatty acid glycerides, polyethylene derivatives, and the like as main components. Chinese patent 102027092a discloses "polyamide emulsifiers based on polyamines and fatty acids/carboxylic acids for oil-based drilling fluids" whose main component is the reaction product of fatty acids with polyamines and mono (poly) polycarboxylic acids. The sorbitan fatty acid ester emulsifier mainly has the defects of easy decomposition and failure under a high-temperature condition, and particularly needs to be continuously maintained and replenished when the sorbitan fatty acid ester emulsifier is used in deep well drilling engineering at the temperature of more than 150 ℃ in an alkaline system environment of oil-based drilling fluid; for the polyamide emulsifier, the emulsifier has a good emulsifying effect at high temperature, but adopts various raw materials, and has a complex preparation process and high production cost.
