肇州201区块油基清防蜡剂的研究

针对大庆肇州201区块原油含蜡量高，凝点高，易结蜡的特点，研制出了效果较好的油基清防蜡剂，确定了最佳配方，并且考察了防蜡剂加量对防蜡率和降凝效果的影响。结果表明，对A油样，1^#防蜡剂加量为1．0％时，其防蜡率可达88．6％，凝点可降低7℃；对B油样，4^#防蜡剂具有较好的防蜡降凝效果。

Research on Oil Soluble Paraffin Inhibitor Used in No.201 Block of Zhaozhou Oilfield

In view of high paraffin content, high freezing point and the tendency to deposit wax on oil well of the crude oil produced in No. 201 Block of Zhaozhou Oilfield, Daqing, several oil soluble paraffin inhibitors of high performance were developed, the optimum formulations of the paraffin inhibitors were identified, and the effect of the addition amounts of the paraffin inhibitors on paraffin control ratio and pour point depression was studied. The results have shown that the paraffin control ratio can reach as high as 88.6% and the freezpoint can be reduced by 7 ℃ by adding 1.0% of 1^# paraffin inhibitor is of good paraffin control paraflqn inhibitor when Sample A is tested, and 4^# and pour point depression effect as well.
