摘　　要：油藏最大接触位移(MRC)储层改造技术可以增大原水平井段井控范围,改变流线方向,深挖局部剩余油,实现单井控水增油效果。A油田目前已进入特高含水阶段,剩余油高度分散,挖潜难度大,尤其是浅层疏松砂岩稠油油藏多口井出砂且治理难度大。S井作为浅层疏松砂岩稠油油藏(M油藏)一口低产低效井,通过实施MRC储层改造技术成功实现了增产效果。该技术的成功应用为海上疏松砂岩稠油油藏剩余油挖潜开辟了新路径,具有广阔的应用价值。The MRC reservoir modification technology can expand the effective well control range of the original horizontal wellbore,change the flow direction,deeply excavate local remaining oil,and achieve the effect of single well water control and oil increase.Oilfield A has currently entered an extremely high water-cut stage,with highly dispersed remaining oil and high difficulty in tapping potential,especially in shallow loose sandstone heavy oil reservoirs where multiple wells have produced sand and it is difficult to control.As a low production and inefficient well in the shallow loose sandstone heavy oil reservoir(Reservoir M),well S has successfully achieved an increase in production through the implementation of the MRC reservoir modification technology.The successful application of this technology has paved a new pathway for tapping the potential of remaining oil in offshore loose sandstone heavy oil reservoirs,presenting broad prospects for its application.
