26 Pieces Of Sea Water Flooding Development Adjustment Technology Research

Growing tensions with liaohe oilfield petroleum resources,the old piece of oil-water distribution is the key of the old oilfield adjustment,we pay more and more attention to the use and development of special reservoirs.Is the sharpening contradictions between the overseas 26 pieces of sea water injection in the oilfield,the effect of the conventional water flooding worse gradually,the well performance mostly liquid producing low and high water cut.For the production of the conventional heavy oil reservoir,structure is relatively complex,and controlled by sedimentary facies belt,at the same time by strong reservoir heterogeneity,oil/water viscosity than the big,has more obvious directivity.Current composite water cut93%,recovery degree of only 19.9%,relatively simple injection alone has been unable to meet the demand of production,to improve recovery factor,next work is difficult.This article mainly USES the method of reservoir engineering and the dynamic analysis method,after the analysis of data collection.This paper mainly on the block more than 400 Wells in the segmentation contrast and distinguish between different layers,and the main layer radial traceability of contrast,divided into static database was established at the same time.And the main oil layer of the single unit sedimentary microfacies analysis and mapping.Using the method of 3 d seismic interpretation 35 km2,mapping area 20 km2,generally met breakpoint implementation,fault combination is reasonable.Reservoir,mainly aimed at the sea of 26 piece of fluid properties and the analysis of reservoir types,and drawing the completed evaluation;According to the actual situation at the same time,redeploy 10 new Wells in the area.Through this thesis research,to improve the overseas river oil field water flooding effect,realize the oilfield long-term production and greatly enhance oil recovery,is of great significance.
