摘要:
通过对伊拉克某油田采出水进行物性分析，找到水质稳定与净化的难点；结合油田采出水的特点，进行腐蚀控制、气提脱硫塔结垢控制及药剂体系筛选的试验，通过模拟计算，选定抗硫腐蚀材料，并在常规采出水处理工艺中加入可酸碱调节气提脱硫工艺，以减少动力提升，最终确定采用调储缓冲+聚结除油+混凝沉降+气提脱硫+两级过滤密闭处理工艺流程，处理后净化水达到油田注水指标要求，即油≤5 mg/L、SS≤5 mg/L、H2S≤20 mg/L。
Abstract:
By analyzing the physical properties of produced water from an oilfield in Iraq, the difficulties of water quality stability and purification are found out. Combined with the characteristics of oilfield produced water, the experimental researches on corrosion control, scaling control of gas stripping desulfurization tower and selection of reagent system are carried out. Through simulation calculation, sulfur resistant corrosion materials are selected, and the acid-base adjustable gas stripping desulfurization process is added to the conventional produced water treatment process to reduce the power consumption. Finally, the closed treatment process flow of regulation and storage buffer, coalescence oil removal, coagulation sedimentation, gas stripping desulfurization and two-stage filtration was determined. After treatment, the purified water met the requirements of oilfield water injection, that is, oil≤5 mg/L, SS≤5 mg/L, H2S≤20 mg/L.
