Design And Implementation Of Inter-well Tracer Monitoring And Interpretation System

The design and development of the interwell tracer monitoring and interpretation system takes into full account the actual needs of current oilfield production,and provides powerful information technology support for oilfield information construction,which has a good application prospect.In order to improve the development efficiency,save time and cost,this system chooses the simple and easy to learn Delphi Pascal language as the programming and development language,and the powerful integrated development platform Embarcadero RAD Studio,and uses the software architecture based on C/S terminal.Agile development mode and waterfall development mode combined with software development thought to develop the system.The whole system is divided into several modules for design,mainly including man-machine interaction interface design module,basic management function module,information input module,data processing output module and information display module.Based on the feasibility and demand analysis of the interwell tracer monitoring and interpretation system,combined with the actual application scenarios and user requirements,the system’s business,function and safety requirements need to be further demonstrated,and the particularity of production and data processing in the petroleum industry is fully considered.The design of the system has four main functional modules,including the basic operating functions of the system(information registration,file opening,file saving,exit system,etc.);Well pattern construction function(well pattern naming,input well group data,delete well data,well pattern construction,define well pattern parameters,etc.);Well pattern calculation function(tracer concentration curve fitting,formation parameter information calculation,injected water distribution information,drawing well group injected water rose map,etc.);Remaining oil saturation calculation function(input chart file and test file,drawing chart curve and test curve,chart method calculation remaining oil saturation,etc.).Finally,the system function module is tested and verified by taking the data of two example well groups as an example,and the well pattern calculation function module is used to numerically calculate the data of two groups of well groups including injection well and production well,so as to obtain the information of injection water distribution,parameters of high permeability layer,etc.,which plays an auxiliary role in decisionmaking for oil field management and technical personnel in terms of adjusting water injection plan and reservoir description.The remaining oil saturation and its distribution are processed and output by using chart method,which has certain guiding significance for oil field managers to adjust stimulation measures.
