The Study On Reservoir Development Pattern In Geng32of Jiyuan Oilfield

For the sake of improving reservoir development effect of Geng32well field in Jiyuan, this paper conducted geologic reservoir research on features of formation,structure, sediment and reservoir. Furthermore, based on the research, a research was made on the reservoir development method and an adjustment was made to Geng32well area’s currrent development manner utilizing numerical simulation methods, which leads to the following conclusions:(1) Further understanding of the features of the formation, structural, sediment and reservoir type according to the researching on reservoir geological features of Geng32well field.(2) Researching the reasonable well pattern and spacing and calculating the development index when waterflooding from the comprehensive various reservoir engineering analysis(3) The distribution of the remaining oil is mainly influenced by geological factors and development.Researching the remaining oil by using numerical simulation.Flood pattern imperfection,Non-mainstream stranded,oilremaining in waterflooding area are the main type of oil remaining distribution. According to the reservoir numerical simulation we can find the favorable layer for adjustment and potential tapping.(4) Well pattern infilling to C1of this oilfield on the basis of basic well pattern and predicted the basic plan and the adjusted plan10years later.
