The Use Of Dynamic Data To Determine The Reservoir Interwell Connectivity

Currently most of oil fields in our country have access to high water or extra high water cut stage after long time waterflooding,the original well pattern can no longer meet the conditions of development.There is an urgent need for well network encryption basing on the relationship between injection and production adjustment.And it is an important problem to judge and analyze the complex well connectivity.Based on the research of the correlation between the reservoir wells and oilfield,this paper proposed a method of calculation of correlation between wells in sandstone reservoirs by the mathematical statistics principle using dynamic data.The using of inter-well correlation model by the dynamic between production data quickly and accurately determine the relevance of wells.This method is applied to the ShengPing oil field in DaQing,predicted results and actual test results prove that this method is accurate and effective.Compared with the traditional identification of reservoir wells connectivity method,this method is convenient,simple and effective without additional test data,which can save a lot of time,reduce research costs and has good application value fieldThe main achievements of this thesis are summarized as follows:1.Heterogeneous identification: identifying reservoir heterogeneity to determine fault location,partition similar to well,reasonable reservoir district2.Identify the main flow direction: calculation and analysis of seepage flow method in local areas,identifying infill well locations;3.Identification seepage channels: identifying the presence of injection and production wells of large pores,water shutoff profile measures were adjusted...
