摘　　要：河南油田稀油老区进入高含水开发后期,剩余油主要分布在厚层中低渗透层层内,层内非均质严重,水淹状况及剩余油分布复杂。为认识和挖潜剩余油潜力,需对地层进行精细描述、对储层重新认识。要求对应的分层开采工艺能够改变生产层位,测试地层压力,以认识潜力层段。目前,井下找堵水工艺技术难以快速测压、可靠地找堵水。为此,在前期智能找堵水工艺研究基础上,开发无线分层测压技术,实现了找水、卡堵水、无线测压的一体化。通过7口井的试验证明,满足了快速改变生产层位、测试地层压力、认识潜力层段的细分开采工艺需要。In the late stage of high water-cut development,the remaining oil of the thin oil in Henan Oilfield is mainly distributed in the low permeability layer in the thick layer.And the nonhomogeneity of the layer is serious.The water is flooded and the remaining oil distribution is complicated.In order to understand and excavate the potential of residual oil,the strata should be described in fine detail and reacquainted with the reservoir.It is required that the corresponding layered mining process can change the production level and test the formation pressure to realize the potential layer.At present,it is difficult to find water and water in the downhole.To this end,in the early stage of the intelligent search for water control technology research foundation,developed the wireless subsection pressure measurement technology,realized the water,the card water,the wireless pressure measurement integration.Through the experiment of 7 Wells,it is necessary to change the rapid production level,test the pressure of formation,and realize the subdivision of the potential layer.
