Characteristics Of Waterflooding In Dongzhi Region, Xifeng Oilfield

Dongzhi Region, Xifeng Oilfield is located in Dongzhi Region of Qingyang and developed at the beginning of this century. Chang8is the main oil-bearing series, which is deep in1850-2050meters, and formational control Oilfield. As a typical low-permeability lithologic reservoir, Xifeng Oilfield has all problems of low-permeability reservoir.Waterflooding characteristic is a important reference for regulation of watcrflooding development. In order to solve above problems, based on previous research results, this paper study this region structural setting geologic characteristic details and comprehensive evaluation reservoir heterogeneity. According to the knowledge of geology connected current status of exploitation, application waterflooding characteristic curve to research waterflood susceptibility of Dongzhi Region, evaluating the waterflood susceptibility, using production data to analysis the characteristics of water breakthrough and water content. Finally, make the propose to the regulation of waterflooding development of Dongzhi Region.The research result of characteristics of waterflooding in Dongzhi Rcgion is important for regulation waterflooding, expectation to enhance oil recovery and waterflooding effect. This result will be a reference to the development of Xifeng Oilfield and low-pcrmcability reservoir simultaneous.
