Shuanghe Oilfield Decision Analysis Fractured Sandstone Reserv Oir Watcrflood Development Plan In Zhidan Oil Region

With the low permeability reservoir development and the deepening of research work, itwas discovered that an increasingly important role in the cracks. First, the flow of crude oil inthe formation and water flooding channels, play to improve reservoir water, oil productioncapacity, changes in lfow characteirstics of low permeability reservoir, reducing the waterpressure. Second, because of the water, open or pressure underground cracks and microcracks crack itself connectivity between the oil wells, resulting in a partial fast irsing watercut wells, water flooding effect is poor, even violent sexual flooded, affecting the overalleffect of waterflooding.Based on the causes of cracks in low permeability reservoirs, the type described，combined with core analysis, fractuirng showed fracture monitoirng and oil wells tests todetermine distribution of Zhidan oil reservoir fracture zone.Select the two are not fiilly invested in Shuanghe oilifeld development block，around thedistirbution of crack, choose from waterflooding way to optimize the deployment of researchWell，OK, and single well pressure system design, well productivity and production speedwith Note expand the amount of other aspects of research, and finally for the emergence ofthe current waterflood development work, and gives a comprehensive adjustment proposalsto improve the ultimate recovery.
