由于降低了酸蚀裂缝的有效闭合压力，砂岩储层注水井酸压比生产井酸压更可能获得成功。
The water injection well of sandstone reservoir may succeed more than production well if taking acid fracturing treatment because reducing of effect closed pressure on acid etching fracture.
随着油田开发的进行，地层压力逐渐下降，水平裂缝趋于闭合，渗透率大幅下降，严重影响了生产能力。
With continuing an oilfield development, its formation pressure tends to decline along with the horizontal fractures being closed, the permeability drawdown and the productivity being damaged.
用于水力压裂设计的一个分析参数。在闭合压力下，当在适当位置没有支撑剂的情况下，裂缝有效地闭合。
An analysis parameter used in hydraulic fracture design to indicate the pressure at which the fracture effectively closes without proppant in place.
对于应力敏感性强的储集层，过低的井底压力降低了近井地带地层的孔隙流体压力，导致裂缝趋于闭合。同时，井壁失稳的可能性也大。
To strong stress sensitivity formation, low BHP reduces pore fluid pressure of near wellbore are which results in the closure of formation fracture.
