From the pressure buildup curve of 16 Wells who used over-high pressure, the skin factor of 14 Wells is negative.
从16口超高压射孔完井的压力恢复曲线统计可知，14口井的表皮系数为负值。
The reservoir pressure of a developed oilfield can be determined not only by shut-in buildup curve for a producing well, but also by shut-in falloff curve of injecting water well.
已开发油田的地层压力既可以由采油井关井的压力恢复曲线确定，也可以通过注水井关井的压力降落曲线确定。
