Dihexadecyl dimethyl ammonium chloride application:

1. Inferior solid-phase flocculants for oil-based drilling fluids

2. Deteriorated solids have a significant impact on the performance of oil-based drilling fluids and are difficult to remove by solids control equipment due to their small particle size. Flocculants can increase the particle size of the poor solid phase through flocculation, but they are almost always used in water-based drilling fluids and rarely used in oil-based drilling fluids. The flocculation effect of dicetyl dimethyl ammonium chloride (DCDAC) on kaolin as a poor solid phase of oil-based drilling fluids was investigated by static observation, turbidity analysis, and microscopic observation. The results show that DCDAC can accelerate the sedimentation rate of kaolin, and when the dosage is 5%, the kaolin is basically settled after 48 h. After 5 h of static observation, the turbidity reduction rate of the kaolin suspension is close to 80%; it is found through optical microscope observation that when the dosage of DCDAC is not less than 4%, the kaolin shows obvious agglomerating behavior; and it is found through the systematic experiments that, after centrifugation, the density of the oil-base drilling fluid and the solid phase content after centrifugation are inversely proportional to the amount of DCDAC, the solid phase removal rate is directly proportional to the amount of DCDAC, and the plastic viscosity and dynamic shear force show a tendency of decreasing and then increasing with the increase of DCDAC, which indicates that DCDAC has a good flocculation effect on kaolin in oil-based drilling fluids, and it can be used to remove the poor quality solid phase in oil-based drilling fluids.
