水力自动调压装置在非均质油藏的应用

Application of hydraulic automatic pressure regulating device in heterogeneous reservoir

水力自动调压装置应用于注水不平衡的非均质油藏,通过装置的自动调节,低压注水井多余的能量转移到达不到配注要求的高压注水井,实现区块均衡注水,从而解决注水井欠注的问题。同时还具有较好的节能效果。该装置与堵水、调驱等增产工艺联合应用,解决了高渗透层被封堵后措施井注水不平衡的问题,可提高区块的注水效率,对区块调整注水方案和稳油降含水具有积极意义。

The hydraulic automatic pressure regulating device is applied to heterogeneous reservoirs with unbalanced water injection.Through the automatic adjustment of the device,the surplus energy of the low-pressure water injection well is transferred to the high-pressure water injection well which can not meet the injection allocation requirements,so as to realize the balanced water injection of the block and solve the problem of insufficient injection of water wells.At the same time,it also has a good energy saving effect.The device,combined with water plugging,profile control and flooding,can solve the problem of water injection from the measure well after the high permeability layer is blocked.It can improve the water injection efficiency of the block and is of significance for the adjustment of the block’s water injection scheme and stabilizing oil and reducing water cut.
