Study On Oily Wasterwater Treatment System In Oil Production Plant

The qualified rate of sewage is a comprehensive index reflecting sewage treatment effect,sewage station water quality and so on,and ensuring the qualified water quality is also a strict requirement for oilfieid water injection.With the deepening of oilfield development,the implementation of various measures for increasing production and the addtion of various chemical agents,the composition of the water producted from the oil field is becoming more and more complex.Reducing the oil content outside the sewage station is the basis of the sewage treatment station and water injection station.The water quality standard will directly affect the water injection situation,even the result of the block.therefore,whether the water quality of the wewage station can reach the standard has a profound influence on the effect of oil field injectionn,the stable production of the oil field and the increas of production.This paper mainly studies the production plant wasterwater treatment system,in order to find out the existing oil production plant in the sewage treatment work,and find out the problems on theory and test solution,the oily sewage treatment work has certain reference in oil production factory.This paper analyzes and studies the formation and treatment mechanism of oily sewage,and selects several sewage treatment methods that are widely applied and operable to conduct in-depth analysis.Not only has a long history,technology mature settling tank oil removal method.Creative use of small experiments to optimize the structure of air tank.The effect of the location of adding medicine and the selection of drug concentration on the effect of sewage treatment was discussed.The far-reaching influence of the normal temperature gathering and transportation on the oil wastewater treatment in the whole oil field is discussed.The adverse effects of the aging oil recovery on the oil system and the water system are analyzed and the countermeasures are put forward.This paper selects several Lamadian Oilfield has certain typical in-depth study of sewage treatment station,a large number of field tests,research to improve oily sewage treatment capacity of the feasibility of the program,through the analysis of the reasons causing water quality standards,resulting in difficult to find several treatment of oilfield sewage and the complete starring factors.The main factor of oilfield sewage containing oil exceed the standard of put forward corresponding countermeasures,countermeasuresinvolve involve gathering,dosing system,settlement system,filtering system and sewage recycling system.This paper summarizes the effective practices of oil production plant in oily sewage,andthe outsanding problems and Countermeasures the current producion,and puts forward and perefects the way to improve oily sewage treatment in oil field and the improvement measures.The new ideas of oil wastewater treatment technology proposed in the oil production plant are of great guiding significance to the actual production in the future.
