摘　　要：为减小原油在集输过程中的流动阻力,在实验室进行了向含水原油中加入DODE系列流动改进剂后的原油流动性实验。结果表明,含水原油中添加DODE系列流动改进剂可以使含水原油的转相点由原来的50%～70%提前到了30%～50%,形成具有适度稳定性的水包油型原油乳状液,有效降低了原油乳状液的表观粘度。To reduce flow resistance of crude oil during transportation,crude oil flowability experiment after addition of DODE-series flow improver into water-containing crude oil was made.The result shows,the addition of DODE-series flow improver into crude oil can advance the phase change point from original 50%～70% to 30%～50%,make the crude oil form oil-in-water emulsion of suitable stability,and thus effectively decrease the apparent viscosity of crude oil emulsion.
