Technical Study On Monitoring And Management Of Oilfield Waterflooding Production System

In this paper, according to the characteristics of oilfield walcrilooding production system,puts forward the basic thought of watcrflooding production system monitoring andmanagement. First of all, monitoring the parameters of oil field waterflooding system; then,according to the relevant index optimization of the whole system, puts forward the reasonableadjustment scheme. The idea runs through the water flooding, the whole period. This articlehas three aspects, which arc the basis of this idea.(1) l’his arliclc given monitoring indicatorsof water Hooding system and developed a real-time monitoring system data. This system canbe the real-lime collection and real-time transmission of the production data. Staff will be ableto real-time understanding of the operation of the whole system in the office.(2) Using thegreat system optimization principle, establish the large system of water flooding the groundsystem and transform the complcx system into a simple subsystem. At the same time, give themathematical model of each subsystem and the relation between system and subsystem.(3)Bythe node analyzing, the underground system of oilfield development has done a detailedanalysis. The commingled water injection is given for the different nodes of the solutionmethod; for the stratified water, not only consider the interaction between layers，but alsoconsider the interaction between injection and production wells, improving the reliability ofthe results.Through the real-time monitoring data, provide data and information on the basis ofanalysis for the next step of calculation. Through the node of oilfield water injectionunderground system analysis can optimize the injection wells, wells work system, optimizingthe hierarchical matching production and injection quantity. Based on the nodal analysisinjection quantity calculation and through optimal control of the water-injection,we can reducethe injection allocation error and improve the eiffciency of the whole system. At the same,time accurate injection allocation rale can improve the efficiency of the underground system.Therefore, the ground and underground system of intcrdcpcndcncc, mutual promotion, so that the whole walcrflooding production system to achieve the optimization, to avoid the localoptimization. The ground and underground system arc the intcrdependenced and mutualpromotion.So that the whole waterflooding production system can achieve the optimizationand avoid the local optimization.
