苏丹Heglig油田生产的稠油对CNPC型降凝剂的感受性变差,改性效果不佳。为了保证管道的安全运行,研制开发了适合当前苏丹混合原油输送的新型高浓度粉末分散型降凝剂,并进行了室内改性效果评价。评价结果表明,该型降凝剂在降凝、降粘及抑制蜡析出等性能均超过了苏丹现在所使用的CNPC型降凝剂。
The heavy oil produced in Heglig Oilfield of Sudan is less sensitive to CNPC pour point depressant and the modification effect is not good. In order to ensure the safe operation of the pipeline, a new type of high concentration powder dispersed pour point depressant suitable for the current Sudan mixed crude oil transportation has been developed and the indoor modification effect has been evaluated. The evaluation results show that the performance of this type of pour point depressant exceeds that of the CNPC type pour point depressant currently used in the Sudan in the areas of pour point depressing, viscosity reduction and wax suppression.
