Study on Harmless Technology of Waste Oil-Based Drilling Fluid

Abstract:

Oil-based drilling fluids are essential for challenging drilling operations. However oil-based drilling fluid after using for the well site and the surrounding environment also poses a serious negative effect. Therefore, for studying on harmless technology of waste oil-based drilling fluid in this paper. Base on the tradition treatment technology for waste oil-based drilling fluid, by the preferred for treatment chemicals, improved the experimental methods and conditions, achieved some research results. Added 8.5g/L xylene/ispropanol complex demulsifier under the 50°C, pH value of 4 conditions to breaking the waste oil-based drilling fluid, the remove base oil rate is 84%, the moisture content is less than 1%, reached the "Twelfth Five-Year" major projects of national requirements' indicators; added 11ml/100g breaker SW-B, 10g/100g lime and 30g/100g cement to system for curing the waste drilling fluid, the solidified strength of the cured than 0.5MPa; Determined to leaching toxicity of solid waste, the pollution index of leaching toxicity of solid waste meeting National Integrated wastewater discharge standard (GB8978-1996).
