The Study On Sedimentary Facies And Fluid Potential Controlling Reservoir Mechanics Glutenite Fan In North Belt Of Dongying Depression

The model of sedimentary facies and fluid potential controlling reservoir forming was created during exploration practice of lithologic reservoir in lowlying zone in Dongying Depression. Owing to actic region at sedimenttary system species,sand body scale,hydrocarbon reservoir category,formational pressure character,and so on,have major diversity in low-lying area,so this is demonstrate actic region glutenite fan facies-potential relation-ship very complicate,also facies-potential holding degree already became affect actic region explorative difficult problem.This research through sequence stratigraphy,to anatomist Donying depression North belt has been already explored classic glutenite fan,such as Li-85 Es4s coastal waters lower fan,Tuo 71 Es3x deep water deepsea fan,Yong-921 Es4s fan delta,and through with fan-body difference microfacies physical property Statistics and analysis,conclusion above-mentioned fan-body beneficial micro-facies,Combine fan-body oiliness definite coastal waters lower fan,deep water deepsea fan,fan deltas,and so on.fanbody facies Control store characteristic classify difference microfacies oiliness limitary physical property rgerange.And according to actual formation pressure data,sound wave well logging data passing dongying depression North belt in longitudinal and horizontal change,regularities of distribution Es4s-Es3s difference layer system formation develop characteristic,moreover difference district develop characteristic has difference , middle part stratigraphic anormaly compression most development,also along with depth shoaling,abnormity high pressure center has regular shifting from east to west.Simultaneity,through oiliness analysis,it is has find out hydrocarbon reservoir always growth at low-pressure area either or high-pressure area relative low-pressure area,so it has disclosure donying depression North belt potential Control store character- istic.In the end, pass facies-potential catenate Control store analyse,to summarize donying depression North belt coastal waters lower fan,deep water deepsea fan,fan deltas facies-potential Control store pattern,and Also difference layer system,difference section facies-potential Control store pattern,established facies-potential Control store quantification formula.and utilize tuo764 glutenite fan to validate established facies- potential Control store pattern with quantification formul legitimacy.
