A percolation model for closed carbonate reservoir with natural fractures was built.
建立了天然裂缝性碳酸盐岩封闭油藏渗流模型。
2
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.
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 switch can be opened or closed when the well pressure is lower or higher than the reservoir pressure respectively.
