Experimental Study on Production Characteristics of Bottom Water Fractured-Vuggy Reservoir

To assess the high-pressure production characteristics of double-vug reservoirs with bottom water in Tahe Oilfield, this study, a physical simulation experiment apparatus is built for water. The “vug-fracture-vug” under different are studied experimentally, and fracture-vug relationship oil recovery rates explored. According to findings, rate significantly affects development effect water, provides sufficient energy reservoir development. Furthermore, considering possible occurrence invasions, control must receive close attention process avoid strong channeling. Constant-pressure has can quickly replenish vug energy. Therefore, percentage invasion retention volume fractured-vuggy constant-pressure higher than those constant-volume Under appropriate factors, presence noticeably improve reservoirs.
