摘　　要：随着油田开采方式多样化,采出水水性发生了较大变化。其中含溶解气采出水、聚合物采出水在反应沉降处理过程中均出现了絮体上浮,造成罐顶浮渣积聚无法排出罐外,以及出水水质含油、悬浮物超标严重的问题。为满足油田采出水稳定达标,针对含溶解气采出水水质特点,在常规采出水反应沉降处理装置基础上对其结构进行了优化改进,研发的双向分离旋流反应沉降水处理装置具有上部自动收渣,下部自动排泥的双向分离功能,实现水质净化处理。该装置采用橇装化、自动化设计。现场应用效果表明:该装置处理后出水水质稳定达标,处理过程加药量减少60%以上,污泥量少,运行费用低,管理方便。该装置的研制有效降低运行成本,具有显著的社会环境效益。With the diversification of oilfield exploitation methods,the water quality of produced water has undergone major changes.Among them,the produced water containing dissolved gas and produced water containing polymers all appeared flocs floating during the reaction and sedimentation treatment process,resulting in the accumulation of scum on the top of the tank and unable to be discharged out of the tank,as well as serious problems that the quality of the effluent water contained oil and suspended solids.In order to meet the stability standards of oilfield produced water,the structure of produced water containing dissolved gas was optimized and improved on the basis of the conventional produced water reaction and settlement treatment device.The bidirectional separation cyclone reaction and settlement water treatment device developed has the bidirectional separation function of automatic slag collection in the upper part and automatic mud discharge in the lower part to achieve water purification treatment.The device adopts skid-mounted and automated design.The field application results show that the effluent quality of the device after treatment is stable and up to standard,the treatment process is less.The development of the device effectively reduces the operating cost and has significant social and environmental benefits.
