新疆油田污水处理后净化水回注跟踪

THE TRACING STUDY ON POURING PURIFIED WATER FROM EFFLUENT DISPOSAL INTO XINJIANG OIL FIELD

离子调整旋流反应法处理技术是对油田污水的离子进行调整从而实现水质净化和稳定,因此处理前污水和处理后净化水中的离子成分和浓度发生了较大的变化,为了考察处理水回注油田对地层的影响、管道的结垢、腐蚀趋势,我们开展了处理水回注油田的水质跟踪评价工作。鉴于六九区稠油污水处理厂、81#原油污水处理站是目前新疆油田最大的两个污水处理站,六九区厂约2/5处理水和81#站全部处理水供采油二厂油田注水,且采油二厂油田辖区有34个开发油藏,其地层特性基本涵盖了新疆油田所有开发油藏的地层特性,因此将采油二厂油田辖区油田的回注作为跟踪评价对象。

The technology on reaction of ion regulation revolving current is to regulate the ion of effluents in the oil field in order to purify water and make its performance stable..The constituents and strength of ion between the effluent and the purified water have changed greatly.To find out the effects on rock formation,the scale and the corrosion of pipe when the purified water is poured back into oil field,we have studied the water quality after pouring treated water back into oil field.There are two biggest effluent disposal factory in Xinjiang oil field,one is 69 Area heavy oil effluents disposal factory,the other is number 81 oil effluents disposal station.About two fifths of treated water from 69 Area factory and all from number 81 station is used to pour back into the Extract Oil Factory 2.As there are thirty-four oil reserves in Extract Oil Factory 2,and its rock formation features contain all the features of the oil reserves in Xinjiang oil field.So we chose the oil field in the Extract Oil Factory 2 as our research subject.
