Study On Assessment Of Impact Of Oil Flooding Development Project To Water Environment

The rapid development of Chinese economy makesthe demand of oil gradually increasingwhich ask us to develop oil more quickly. Most of Chinese region is poor in oil resources. Atpresent, large shares of Chineseoil areproduced by water flooding development technology. Oilwater flooding development projects are abundant and widely distributed in Chinese oil fields.They produce vast amount of petroleum. Meanwhile they lead to the escalating waterenvironment crisis. How to scientific assess the impact of water flooding development to waterenvironment becomes a problem with vital importance.In this dissertation, study the process, technologies and environmental effect of oil floodingdevelopment project, thenanalysis the impact process and resultsof oil flooding developmentproject to water environment. According to the thought of analytic hierarchy process, study theimpact assessment method of oil flooding development project to the water environmentalquality and quantity. Then assess their impacts using the linear weighted method. Construct theassessment index of resultant effect of oil flooding development project to water environment.Build dynamical assessment model of resultant effect of water environment using the assessmentindex. According to a case of oil flooding development’s impact to water environment, use theabove assessment methods and models to evaluate the effect of the project to waterenvironment.Theresults show that the assessment index and models can effectively assess theimpact of oil flooding development to water environment in this dissertation. The researchresults cover the shortage the impact assessment of oil flooding development project to waterenvironment.Moreover, the assessment index and dynamical assessment model of resultant effect of oilflooding development project to water environment can be widely used on the effect assessmentof oil development project to water environment. If some softwareis developed in light of thestudy results, it will be widely applied in the assessment of oil development projects.
