摘要
根据水力压裂措施的实际情况，描述了部分贯穿地层的垂直裂缝井的物理模型和数学模型，求得了井底压力计算公式。提出了裂缝贯穿度和裂缝总导流度的概念，并分析了它们对理论曲线的影响。通过实例分析说明了该模型的特点和实用性。
According to the hydraulic fracturing treatment, the partially fracturing physical model and mathematical modelare described. The wellbore pressure calculation formula are got. The concepts of fracture penetration and totalconductivity ratio are built-up and their effects to the type curve are analyzed. By analyzing the feild data, thecharacter and useability of the medel are demonstrated.
