| Abstract: | In view of the development of unconventional oil and gas reservoirs and safety drilling in complex formations, the research and application of oil-based drilling fluids are carried out to solve wall stability of horizontal well, friction, cuttings carrying and formation pollution. Oil-based drilling fluid formula with diesel and white oil as base oil, circulation loss control technique and on-site operation process were formed by the study and selection of emulsifier, organic bentonite, filtrate reducer, plugging agent and some other treatment agents, which met the construction requirements in the application in more than 100 wells in Fuling with favorable technical and economic effects. Combined with the specific conditions of Fuling block, intensive study was continued, field tests of powder emulsifier and non-bentonite oil-based drilling fluid were made in 2015. |
