一种乳液型钻井液润滑剂的制备及性能评价
Preparation and evaluation of an emulsion-type drilling lubricant
摘要
Abstract
Polyamine ,cottonsee d oil and low carbonate are taken as raw material to synthesize the vegetable oil amide . The optimum synthesis conditions are :the molar ratio of the polyamine , cottonseed oil and low carbonate is 1∶4∶1 ,the reaction temperature is 168 ℃ ,the reaction time is 2 .5 hours;Using amide synthesis products as the main raw material ,NaOH and oleic acid generated sodium oleate as emulsifier ,using silicone paste ,kerosene and CMC‐HV as additive ,O/W emulsion drilling fluid lubricant was prepared by the agent‐in‐oil method ,and the optimal proportions are as follow s :vegetable oil amide sample 8 w t% + oleic acid 10 w t% + kerosene 18 w t% + silicon cream 2 .5 wt% + NaOH 7 .14 wt% (NaOH solution concentration is 20 wt% ) + CMC‐HV 0 .1 wt% +water .The performance evaluation shows that the lubricant has superior lubricating properties and the decreasing rate of drilling fluid lubrication coefficient is not lower than 80% when the amount of lubricants is 0 .5 wt% ,and drilling fluid rheological behavior and density are not affected .The drilling fluid lubrication coefficient is lower than 0 .10 after being high temperature aging at 170 ℃ and put in 15 wt% saline mud .The lubricant shows a good performance of temperature and salt resistance .关键词
