Research of Water Flooded Performanceand Pattern in Horizontal WellWith Bottom-Water Drive Reservoir

摘要

The significant difference exist in water floodedperformance of different horizontal wells, and many influencingfactors including heterogeneity, horizontal well length, locationand trajectory would play effects on water flooded performanceof horizontal well. Based on the production data of horizontalwells with bottom water reservoir in TZ402CIII and numericalsimulation for production history matching, this paper studiedhorizontal well water flooded performance and its influencingfactors, for the first time demonstrated that water floodedpatterns of horizontal wells with bottom water reservoir inTarim Basin was classified into three categories composed ofline breakthrough water flooded the whole horizontal section, punctiform breakthrough water flooded the whole horizontalsection, punctiform breakthrough water flooded the localhorizontal section. The results would be used to qualitativelydesigning horizontal well, determining the completion plan forhorizontal well, evaluating the development potentiality to lateproduction period in horizontal well, and determininghorizontal well candidate for measure treatments(e. g. water-shutoff, hydraulic fracturing or acidizing for horizontal well)inmid-late production period.
