Abstract: After 40 years of development, Shuanghe oilfield is in the period of ultra-high water cut development stage at present. The target of tapping potential has shifted from the initial thick layer to the medium-low permeability thin interlayer. Fracturing measures are the most effective means to tap the potential of such lowgrade reservoirs. Conventional fracturing technology is difficult to control artificial fracture and water cut after fracturing. Therefore, on the basis of studying the influence of geological and engineering parameters on artificial fracture height, this paper draws up the boundary chart of stress difference and barrier thickness, which provides scientific basis for thin interlayer fracturing well selection, and evaluates the permeable and water-resisting proppant and fracturing water shutoff agent with good water control effect. The field application results show that the compound application of oil permeability and water blocking proppant and fracturing water plugging agent plays a relatively obvious synergistic effect and the effect of water control and oil increase, which widens the application range of fracturing technology in high water-cut oilfield and has a good application prospect.
