Shengli oilfield
shengli oilfield The technology of recovery recovery is improved. The technology for the adjustment of oil flow field in the later stage of high water cut. In this paper, a quantitative description method of high water consumption layer is formed, and the key technology of flow field adjustment is studied. Tuo 11 south block on the longitudinal rhythmite note, flat surface turn streamline basins, the unit of nissan 355 tons of liquid drop, nissan increased by 17.7 tons of oil, tons of oil costs fell 142 yuan, is expected to extend the economic life period of 5.4 years. The technology of deep blocking in the high water-cut stage of the whole oilfield. Form deep displacement technology step by step, with implementation of extreme high strength resides deep sealing channeling, for strongly watered-out zone "mobility + phase permeability" double regulation, the weak water drive belt to improve the water displacement ratio, contain invalid water injection cycle. ...
