The Technology Of Produced Water System Treatment For The Field

At present,the most national oilfield has developed a long time,the water percentage in the production has more than 80%,so will produce a large volume of additional contaminant-oily sewage.In order to purify oily waste water and up to the standard of injection water and discharge water,developing and researching new technologies and new processes has become a major task in each oilfield.Based on the actual situation of sewage treatment in No.9 Oil Production Company,through the practical field investigation,sampling test and data analysis,the paper analyzes the influence to deal with problems of water quality.Surveysing four sewage treatment station at LonngXlian,GuXilian,AoXlian,XinXlian,through the field test data analysis,according to different problems of the four joint station,such as the excessive sulphide,the excessive sulphate reducing bacteria and the excessive dissolved oxygen,formulates the corresponding treatments.According these treatments,the company solves the emission problem of sewage treatment facilities,safeguard the stable quality of injection water,effectively protect the field environment.
