Preparation and Performance of Wax Emulsionusing in Drilling Fluid

Abstract:

An O/W type paraffin wax emulsions was prepared using Tweenand Span emulsifiers, and liquid paraffin. The influences of temperature, HLB and surfactants concentration in particle size of paraffin wax emulsions were studied, as were the stability of paraffin wax emulsions. The application performances in drilling fluid of paraffin wax emulsions were researched with respect to artificial core line swelling and shale recovery. Results showed that the best conditions of preparation of emulsified wax: surfactants concentration was 5%, temperature was 50°Cand HLB was 10.1-10.5. It was found that paraffin wax emulsions possess strong inhibition ability for hydration, swelling and dispersing of clay and shale. The inhibition ability of paraffin wax emulsions enhanced with KCl.
