Research On The Reservoir Oil&Water Distribution Rules Of Wuerxun Oilfield1^st Member Of Nantun Formation

Resume: Wuerxun Depression in the southern region is the Hailar Basin, one of themajor exploration, due to tectonic sedimentary evolution of the complexity of the sequencestratigraphic framework of the development within the sedimentary facies configuration style,a clear understanding of sand body distribution, resulting in the type of oil and gas reservoirsand distribution, oil and gas accumulation in the lack of in-depth understanding of controllingfactors. Ukraine in particular, the eastern slope of the region has shown the complexrelationship between oil and water, its controlling factors of exploration and development hasbeen a major problem, it is necessary and sedimentation from the construction of the twobasic frame of analyzing, in-depth analysis of the distribution and control of oil and waterfactors, the next step exploration.Through the comprehensive use of seismic, well logging, mud logging, core, productiontesting and development wells produce dynamic geological information and reservoirdescription of the development within the fault system and the distribution of closed and opennature of fracture; right within the reservoir and distribution characteristics of fracturedevelopment described; study the distribution of the relationship between oil and waterreservoirs and reservoir type; On this basis, the analysis can change the oil and Fisheries. First,to different strata sand body distribution rule research, carried out single-well andsingle-sedimentary microfacies study of sand body fabric. Second, to conduct fault systemsand different strata fault sealing assessment, analysis of fracture formation and evolutionhistory, evaluation of different strata of lateral sealing faults, analyze fault and the differentstrata of the relationship between oil and water. And then oil-water distribution of the differentstrata on the use of test data and development of oil-dynamic data, analysis of different layersbit-plane and vertical distribution of oil and water. Finally, the distribution of the different strata of the controlling factors of oil and water analysis, based on the above-mentioned studyon the distribution of the different strata of the factors affecting the oil and water analysis todetermine the controlling factors. The direct guidance of the project findings Wuerxun oilfield development on the Hailar Basin rapid increase reserves and production, developmentand deployment and extend the edge of important guiding significance, for the sustainabledevelopment of Daqing oil field has a significant impact and significance.
