injection water

In condition of long-term high production pressure difference, forced injection and forced production are external factors. The residual oil is difficult to recognize due to very higher water-bearing resulting from the early forcible injection water for pursuing higher production.

长期大生产压差条件下，强注强采是导致储层伤害的外在因素。由于初期强注强采，含水上升幅度大，剩余油认识难度较大。
