Abstract
The influence of oil recovery on theology of waxy crude oil processed by nano-based pour point depressant was studied.The results show that nano-based pour point depressant for highly waxy crude oil is effective in reducing solidification point and viscosity.The depressant was heated to 65 ℃,solidification point reduced to 17.5 ℃;The flow behavior under low temperature was better than oil temperature rise less.the oil temperature rise to 35 ℃,then reduced to 30 ℃,the solidification point is 24 ℃ under test.The solidification point of chemical modified crude oil retain steady under repeat heat by 5 times,the stability is good and can support the transportation of highly waxy crude oil safely and economically.
