| 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 antiscale effect. |
