高效自适应微气浮除油技术在海上重质油田生产水处理中的应用

Application of Highly Efficient Adaptive Mini-Swirl Flotation Deoil Technology in Produced Water Treatment of Offshore Heavy Oil-Field

摘要: 本研究介绍了一种新型紧凑式高效自适应微气浮除油技术在渤海某重质油田平台生产水处理过程中的应用。该成套技术设备在入口生产水含油1500~2500 mg/L，流量250 m³/h，压力250 kPa，原油密度0.92~0.96 g/cm³的条件下，出口平均油含量106.1 mg/L；海上平台设备处理能力及占地空间的综合评价指标FA为16.85 m/h，FV为5.61 h⁻¹，较传统斜板除油器，在提升除油效率的同时，占地面积缩小了61.1%；在体积上，仅为旋流除油器体积的50%。该技术可适应较大流量波动及较宽范围油含量的条件，为现有海上油田平台生产水扩能改造提供了技术支撑。

Abstract: This paper introduces the application of a new compact and highly efficient adaptive mini-swirl floatation deoil (AMFD) technology in the process of produced water treatment in a heavy oil-field in Bohai Sea. Under the conditions of 1500~2500 mg/L oil content of inlet produced water, flow rate of 250 m³/h, pressure of 250 kPa and crude oil density of 0.92~0.96 g/cm³, the average oil content of export is 106.1 mg/L. The processing capacity parameter FA of offshore platform devices is 16.85 m/h. The evaluation parameter FV of occupied space is 5.61. While improving the oil removal efficiency, AMFD separator is 16.7% smaller than the traditional slant plate deoiler. In terms of volume, it is only 50% of the volume of the cyclone deoiler. This technology can adapt to the condition of large flow fluctuation and provides technical support for the produced water expansion and transformation of the existing offshore oil field platform.
