Gaotaizi Infill Development Evaluation And Optimization Measures

Central Western Gaotaizi infill wells put into development in 2009, due to multiple encryption development wells for the purposes of reservoir, reservoir physical property is poor and close to the high aquifer, the block based water higher than expected water, water cut rising fast, within a relatively short time into extra high water cut stage mining. As a further extension of the oilfield stable production period, the realization of "stabilizing oil production and controlling water" goal must make clear the remaining oil distribution, to take timely measures for tapping potential method.Central Western Gaotaizi encryption well network has entered extra high water cut stage mining, injected water inefficient invalid cycle seriously. Through dynamic, static data comprehensive analysis, looking for remaining oil enrichment zone. Aiming at different reservoir sedimentary microfacies and single sand body use, water flooded condition, optimize measures. Summed up the practice of mining process understanding, to solve the influence factors and find out the potential of single well, and vigorously promote the fine analysis, fine potential tapping, precise measurement, through combination adjustment of oil and water wells, development effect reached the limit, for water flooding of extra high water cut stage control of tap water "to provide certain theoretical and practical basis.The Sazhong area of Central Western Gaotaizi block as the research object, the status of the development of geology, the block, the residual oil potential, and the main problems of block are analyzed. In the evaluation of the effect of water flooding was evaluated from time to time, mainly from the single well measures of variation of high water cut period measures effect. In the optimization method of the block production system, the main work is as follows, are studied with the single factor influence factor analysis method and grey correlation method for all kinds of measures, using fuzzy comprehensive evaluation method to measure parameters of ideal wells were optimized, which has certain guiding significance the central Western Gaotaizi oilfield development evaluation.Established a water flooding adjustment and tapping the potential effect evaluation system, study the variation of block in the extra high water cut period to the effect of different measures. Water flooding potential measures to optimize the system has been set up, of all kinds of measures to optimize the parameters and provide various measures of collaborative optimization.
