摘要
某油田进入高含水开发后期,采出原油具有“双高”(含蜡高、含水率高)特性。在机采管理上,由于洗井不及时、套喷生产、关井时间长等原因,导致部分井的管、杆结蜡,严重时油管、套管均会出现蜡卡堵现象。应用强磁防蜡器可有效减少因结蜡导致的油井产量下降、能耗升高、泵况异常等问题,现场试验结果表明强磁防蜡器能够有效降低蜡质的形成及附着,起到了良好的降黏及抑制蜡晶的作用,最高可降低原油黏度40%左右,降低结蜡率30%,达到了清蜡、防蜡的目的,预计全年可节电50×10^(4)kWh,节省用电成本40万元,实现了节能防蜡的效果。
An oilfield has entered the late stage of high water content development,and the crude oil produced has the characteristics of"double high"(high wax content and high water content).In terms of mechanical production management,due to untimely well flushing,casing blowout production,long shut-in time and other reasons,some well pipes and rods are waxed,and both tubing and casing will be stuck with wax in serious cases.The strong magnetic wax prevention technology should be applied to effectively reduce the decline in well production,increase in energy consumption and pump inspection problems caused by wax.The field experiment results show that the strong magnetic wax preventer can be effectively reduced the formation and adhesion of wax,and has a good effect of reducing viscosity and inhibiting the formation of wax crystals.The maximum viscosity of crude oil can be reduced by 40%,and the wax deposition rate can be reduced by 30%,which achieves the purpose of wax removal and wax prevention.It is estimated that the power saving of the whole year can be saved 50×10^(4) kWh,saved electricity costs of 400000 yuan,and achieved the effect of energy conservation and wax prevention.
