| 摘要: |
| 根据原油防蜡剂的作用机制,通过分子设计,以甲基丙烯酸十八酯(O),马来酸酐(M),苯乙烯(S)作为为共聚反应的单体,过氧化苯甲酰(BPO)作为引发剂,甲苯为溶剂,采用溶液聚合的方式合成三元共聚物OMS,考察其最佳合成条件。结果表明:在n(O)∶n(M)∶n(S)=9∶1∶1、反应温度为90 ℃,w(BPO)=1.2％、反应时间为8 h的条件下,合成的防蜡剂对新疆油田的油井防蜡率可以达到50％;OMS与OP型表面活性剂复配后,防蜡效果更好,且防蜡剂具有一定的降黏降凝作用。 |

| Abstract: |
| According to the mechanism of wax prevention of crude oil, taking octadecyl methacrylate (O), maleic anhydride (M), styrene (S) as monomer of polymerization, benzoyl peroxide (BPO) as initiator, toluene as solvent, the terpolymer OMS was synthesized by solution polymerization through molecular designing. And the optimum synthesis conditions were also discussed. The results show that the optimum reaction conditions are as follows:the molar ratio of octadecyl methacrylate to maleic anhydride and to styrene is 9∶1∶1, reaction temperature is 90 ℃, the amount of BPO is 1.2％, reaction time is 8 h. The wax inhibiting rate of the paraffin inhibitor could reach 50％ in Xinjiang Oilfield. While mixed with OP surfactant, the wax prevention effect is better, and the paraffin inhibitor has pour point reduction and viscosity reduction effect. |
