Research On 3D Fine Geologic Modeling And Tertiary Infilling In A Block Of Xinli Oilfield

A block of xinli oilfield field under the present reservoir and development problem is the oil well productivity is relatively low;Block basic well pattern development,the degree of water flooding effect is poor;Strong reservoir heterogeneity,the water injection development effect;Reservoir physical property is affected by sedimentary microfacies belt is very big,main performance in oilfield contains high Wells increasing year by year,ineffective water cycle is relatively serious,the contradiction in vertical plane and find out the spatial distribution of the high permeability zone by geological modeling,further development of perfect combination of tone,plugging,take governance techniques of invalid water cycle system.Aiming at the problems above,hope that through the development of the fine geologic modeling project in new region,have pure and fresh state of low permeability reservoir physical properties,oil content lower limit standard method,and the logging interpretation model of reservoir physical property,oiliness method;High precision structure and phased geological model is established,dynamic reservoir description and potentialities and clear direction for the next step.The project for the research focusing on oilfield development scheme for comprehensive adjustment and potentialities and provides geological basis for the next theme,make full use of the relevant basic data in the study area,based on the study on the relationship between the"four sex",determine the division standard of reservoir,combined with the original logging interpretation models of reservoir physical properties,the research of single sand body distribution and the connecting relation,then 3-d geological structure model and the phase of reservoir attribute model was established,on the basis of above study,the model application reserves change double calculation and comparison analysis and predict favorable zones,the application of numerical simulation to determine the well pattern adjustment model,and predict the development indexes change after the situation,the oil field adjustment and potentialities and clear direction,and making sexual strong encryption adjustment plan.
