    Abstract
  • Drilled cuttings of low quality have great influence on the properties of oil base drilling fluids and are difficult to remove because of their small particle sizes. Flocculants can be used to enlarge the particle sizes of the drilled cuttings through flocculation but are generally used in water base drilling fluid and seldomly are used in oil base drilling fluids. An oil base drilling fluid contaminated with kaolin as the poor-quality solids was studied for the flocculating performance of dihexadecyl dimethyl ammonium chloride (DCDAC) to flocculate kaolin. Observation of the contaminated and DCDAC treated oil base drilling fluid under stationary state, turbidity analysis and observation under microscope of the drilling fluid showed that DCDAC is able to accelerate the settling of kaolin particles; at 5% of DCDAC in the kaolin containing oil base drilling fluid, all the kaolin particles settled to the bottom in 48 hours. After kept stationary for 5 hours, the percent decrease of the turbidity of a kaolin suspension was nearly 80%. Observation under microscope of the drilling fluid showed that when the concentration of DCDAC in the oil base drilling fluid was greater than or equal to 4%, the kaolin particles showed obvious agglomeration behavior. It was also found in the laboratory experiment that the density and solids content of an oil base drilling fluid after centrifugation are inversely proportional to the concentration of DCDAC, while the percent removal of solids is in direct proportion to the concentration of DCDAC. With the increase of the concentration of DCDAC in the oil base drilling fluid, the plastic viscosity and yield point of the drilling fluid were first decreasing and then increasing. All these phenomena shown in laboratory experiment indicate that DCDAC has good flocculating capacity to kaolin in oil base drilling fluids, and can be used in removing low quality solids from oil base drilling fluids.
