目的：探寻合金防垢在某油田的适用性。方法利用设计的模拟试验装置，以防垢效果为评价指标，优选出作为合金防垢器核心部件合金扇形片的元素配比，设计并研制扇形合金片螺旋排列结构的串联式合金防垢器，选择油田的油井进行5个月的现场试验。结果地层水中的钙镁离子质量浓度提高了260%，防垢率较化学阻垢提高了76%。结论该合金防垢器防垢效果较好。%Objective To explore the applicability of alloy antiscale in certain oilfield.Methods A simulation test device was designed, and the scale prevention effect was selected as the evaluation index, the ratio of elements as material for the alloy segment, which was the core component of alloy antiscale device, was optimized, and tandem alloy antiscale device with spiral arrangement structure of segments was designed and developed. Finally, a 5-month field test was conducted in wells of oilfield. Results The calcium and magnesium ion mass concentrations in formation water were increased by 260%, and the anti-scaling efficiency was 76% higher than that of chemical anti-scaling.Conclusion The alloy antiscale device showed relatively good an-tiscale effect.
