| 摘 要： | 对Joshi水平井产能公式进行了分析,指出了Joshi水平井产能公式不足之处,其一是为垂直面流动计算引入的复势与假设不一致;另外是非均质储层水平井产能公式存在局限性。通过坐标变换,以及垂直流动面和水平流动面取不同的渗透率,对Joshi水平井产能公式进行修正,提出了一个新的渗透率各向异性储层水平井稳定产能公式。最后,通过现场水平井实例对比,验证了新公式的合理性。

| Abstract: | Joshi’s horizontal well productivity formula was analyzed in this paper, and its two disadvantages were presented. One is an existing inconsistency between the hypothesis and the potential applied in vertical radial flows, the other is a conditional formula in anisotropism formation. By coordinate transformationand with different choices of permeability in perpendicularity and horizontal direction, Joshi horizontal well productivity formula was modified. A new horizontal well productivity formula in isotropism and anisotropism reservoirs were developed. Furthermore in contrast with an oil field example, the results show that the production predicted by new formula is in good agreement with the flied. |
