- Abstract
The crude oil in Hainan Fushan Oilfield has the characteristics of high pour point(PP) and bad low temperature flow properties. Based on the analysis of Fushan crude oil physical property and test results, the pour point depressant(PPD) FJ-2 was synthesized by the graft copolymerization of vinyl acetate copolymer and modified alkyl amide polymer, which had good susceptibility with the crude oil. The property evaluation results showed that the optimal concentration was 300 mg/L with the optimal heat treatment temperature 50 C The solidification point of the crude oil reduced from 23 C to 8 C At 20 C the apparent viscosity of the crude oil with a concentration of 300 mg/L was decreased from 918.3 mPa.s to 165.2 mPa.s with viscosity reduction rate at 82%; yield value was decreased from 35.17 Pa to 1.05 Pa, with yield value reduction rate at 97%. In addition the crude oil treated by FJ-2 had good static stability. The field application showed that the FJ-2 had good adaptability with the crude oil in Hainan Fushan Oilfield, and could lower the pour point, improve the low temperature flow properties of the crude oil.
