Waterflooding Development Program Of Pingyaoxian Block Area In Wang Jiachuan Oil Field

Wang Jiachuan chang6 reservoir of pingyaoxian block belongs to the typical low permeable lithologic reservoir, buried shallow, low pressure, poor physical property.Must through fracturing to put into production, since the oilfield development mainly rely on natural energy production way.At present Oil Fields is at a "three low one fast development stage (namely low single-well production, low production rate, low recovery efficiency; rapid production decline), poor development effect; Cause the lreservoir pressure drop is too large, underground energy deficit, low recovery degree.In order to ensure the oil field water injection development effect, achieve long-term stable oil and controllable water goal, ensure enterprise benefit and social benefit in the long run. According to the pingyaoxian block area geological characteristics, ensure the efficient development, prepare a set of suitable for the actual production situation of oilfield, operable, timely used in oil field in the near future and long-term construction of water injection development plan. In order to ensure the integrity of the water injection scheme establishment and the scientific nature, has carried on the field research, and according to the research situation of oil well pattern arrangement schemes repeated adjustment, repeated demonstration and optimization, and finally determine the waterflood development design, completed the project research content.
