The Technology Research Of Sewage Water Treatment In The Xianhezhuang Oil Field

Xianhezhuang Oil Field With the continuous deepening of water flooding, reservoir water quality of the injection have become increasingly demanding, "fine water" has become effective to improve waterflooding to improve oil recovery key technologies and basic premise. But at present Xianhezhuang oilfield wastewater quality there are many outstanding issues, such as water corrosion and scaling problems remain severe, along the water injection system in the secondary pollution problems have become increasingly prominent, the pharmaceutical dosage gradually increased, operation and management costs continue to rise. To solve these problems, this article in full investigation and study domestic and international oilfield wastewater treatment technology in the current situation and Xianhezhuang oilfield sewage water analysis and applications of sewage treatment technology, based on nodal analysis method in accordance with the system right major contradictions and problems faced by in-depth analysis, the source of the sewage water has carried out a detailed water analysis, corrosion and scaling mechanism analysis, water purification tests, electrochemical pre-oxidation technology field testing, water quality, coMPatibility testing, and pharmaceutical formula optimization, while the downstream water quality protection system along the way technology was studied, explored, tried the water washing pipe gas mixing technology, come to the law of the relevant tests, in the comprehensive management of water quality has made some progress, and put forward the next step wastewater treatment technology ideas and direction.By Xianhezhuang oilfield effluent quality comprehensive evaluation, analysis, and technological innovation, the initial establishment of a systematic operation and management of water quality model, so as to develop oil field injection water treatment has provided the data and ways you can learn from.
