Research on High-efficiency Lubricants for Water-based Drilling Fluids in Shale Reservoirs
摘要
Abstract
In order to improve the lubrication performance of water-based drilling fluid for horizontal well drilling in shale reservoirs and enhance drilling efficiency,an efficient lubricant RH-1 was prepared using recycled vegetable oil,low-carbon alcohols,fatty acid amides,polyethers,and nanomaterials as the main raw materials.The preparation conditions of high-efficiency lubricant RH-1 were optimized through indoor lubrication performance evaluation experiments,and its influence on the performance of on-site water-based drilling fluid system was evaluated.Its temperature resistance and environmental performance were examined.The results showed that when the concentration of catalyst was 0.5%,the reaction temperature was 160℃,and the reaction time was 2.5 hours,the lubricating effect of the prepared high-efficiency lubricant RH-1 was the best.When its dosage was 3%,the reduction rate of lubrication coefficient of the base slurry could reach 85.8%.The compatibility of high-efficiency lubricant RH-1 with on-site drilling fluid is good,and the recommended optimal dosage is 3%.The lubrication coefficient of drilling fluid can be reduced to 0.095,and its impact on the rheological and filtration performance of drilling fluid is relatively small.The high-efficiency lubricant RH-1 also has good temperature resistance and environmental performance,and can still exert good lubrication effect after aging at 150℃,with strong adaptability.关键词
