Optimization Of Polymer-bea Treatment Technique In Sa B Candidate: Qin Zhi Hiu;optimization Of Polymer-bearing Sewage Treatment Technique In Sa Bei Oil Field

This paper discusses the influence of Sabei development factors of water quality standards, and by relying on scientific and technological progress, new technology, new technology, and by modification measures to arrange sewage system of injected water quality has been improved, and the existing problems, and adopted a series of measures and conduct a targeted research. In order to solve the Daqing oilfield walnut filter tank run filter material, flush pressure-out and unstable, suspended after water injection solid content than the actual problem, index of reasonable filtering tank walnut flush parameters and operation mode, the treatment effect of the improved filtering tank walnut, Company development organizations, by No.3 oil field, design, develop the walnut filtration flush test parameters. The field experiment in a large amount of data, based on the analysis of the optimal selection flush strength, flush time and mixing way, for the reverse design parameters and operation mode, provides reference for feasibility, To improve the effect of walnut filtration technology flush water filter, improve after, provide a powerful guarantee. For filtering process does not adapt the current quartz produced water quality characteristics of filter materials, loss, damage, pollution, structure, develop filter material erosion mechanism and improving technology research. Through the field test and optimize the filter material flush inflation height and filter materials, density and intensity of flush, and the mathematical model of relationship between further optimization model, flush filter material harden the formation mechanism of formation, and pollutants (polymer, bituminous, colloid, oil mixed), analyzes the quantitative relationship between filter material harden degree of reverse wash inflation altitude, determine the filter material loss and improvement measures mechanism and technology research and field test. For ternary effluence emulsification serious difficulties, the oil-water separator, suspended solid content, too difficult problems, such as the previous test base on center Wells effluence process test and north west of three crude oil dehydration and ternary experiment stations and recovery liquid sewage treatment chemical screening tests. Through the field test, evaluation of existing technology conditions for ternary effluence processing of adaptability, suitable for weak ternary effluence processing process and technical line, parameters and treatment reagent for final weak alkaline ternary effluence treatment process and technical parameter to provide reliable basis. Finally puts forward step down to storm a strategic pass, and research direction of water quality improvement work again in Sabei oil field on the new level.
