中文摘要:
      目的 通过对延长油田JX区块腐蚀结垢情况分析,针对性地研制并筛选缓蚀阻垢剂配方,获得阻垢、缓蚀效果最佳的HAP缓蚀阻垢剂。方法 采用EDTA滴定法、称重法和腐蚀挂片分析技术,在温度为90 ℃时,对缓蚀阻垢剂的缓蚀效果和阻垢性能进行评价,通过反复对比分析,筛选配方,并进行了现场试验。结果 与未添加缓蚀阻垢剂时相比,油井产出液分离水的腐蚀速率由0.125~0.161 mm/a下降到0.023~0.034 mm/a,缓蚀率达到了80%以上;混合结垢量由130~290 mg/L下降到7~15 mg/L,阻垢率达到了91%以上。结论 应用EDTA滴定法、称重法和腐蚀挂片分析技术优选了缓蚀阻垢剂配方,在高温环境下,缓蚀阻垢剂综合性能优良,现场试验中的缓蚀阻垢效果显著。
英文摘要:
      The work aims to acquire HAP corrosion and scale inhibitor exhibiting the best corrosion and scale inhibition effects by analyzing corrosion and scaling in Block JX of Yanchang Oilfield, developing and screening formulas of corrosion and scale inhibitor specifically. The corrosion and scale inhibition performance of corrosion and scale inhibitor was evaluated at 90 ℃ in EDTA titration method, weighing method corrosion coupon analytical technique. Through repeated comparative analysis, the formulas were screened and field tests were carried out. Compared with that without corrosion and scale inhibitor, corrosion rate of water separated from oil well-produced liquid decreased from 0.125~0.161 mm/a to 0.023~0.034 mm/a, the corrosion efficiency reached over 80%. The amount of mixed scale reduced from 130~290 mg/L to 7~15 mg/L, the scaling inhibiting efficiency reached over 91%. Formulas of corrosion and scale inhibitor are screened in EDTA titration method, weighing method and corrosion coupon analysis technique. The corrosion and scale inhibitor exhibits excellent comprehensive performance. The corrosion and scale inhibition effect is remarkable in field tests at high temperature.
