Research And Application On Calculation Methods Of Economic Reserves

Most of the oilfield has entered the middle-last stage of development in ourcountry at present. The remaining reserves of the stage are reduced and the difficultyof the mining are increased, in order to achieve the purpose of increased productionand stable production, some wells of oilfield l will implement measures.With increased difficulties of mining, how to optimize measures workload ofoilfield to get better economic benefits and complete production,which become aimportant problem.According to the practical production situation of oilfield, to set upa variety structural optimization mathematical models of oilfield measures yield,withrespectively the lowest cost of investment,the largest and benefit for the best goal ofsingle objective programming model.And the lowest cost of investment,the largestand the least of water yield for the goal of multi-objective programming model.Through the simplex method to solve single goal programming model,Multi-objectiveprogramming model through the linear weighting method into the single objectiveprogramming model,then through the simplex method to solve.The mathematicalmodel is applied to the specific examples of oilfield,by studied and analyzed,to get theright measures workload arrangement plan,which according with the actual requirementand have a good application.When yield and measures workload confirmed,the least cost of investmentoptimization model for the first solution plan,when investment costs and measuresworkload confirmed,the most of yield optimization model for the second solutionplan,And when yield and cost confirmed,the best of benefit optimization model forthe third solution plan.The actual data of the victory oilfield in2008as an example,through the fuzzy comprehensive evaluation method,the different goals for the largestof yield,the least of measures expenses smallest and the best of benefit carry throughthe selection sequence,to get the right solution for the structural optimization model ofthis oilfield measures yield,when yield and cost confirmed,the best of benefitoptimization solution plan.
