| 摘 要： | 针对钻井液、完井液等液体浸入对近井带地层所造成的伤害,在建立地质模型时,将伤害带进行了各种不同的假设,并定性地绘制出渗透率变化图形,再利用等值渗流阻力方法和裘比公式以及达西定律,得到了各种不同模型下的表皮系数的计算方法。

| Abstract: | Aiming at the damage caused by fluid immersion such as drilling fluid and completion fluid, different hypothesis on the damage zones has been considered during the process of establishing geological model, and then a permeability variance diagram is qualitatively drafted. By u-sing equivalent seepage resistant method, Qiubi formula and Darcy law, the calculation method of skin factors under different models has been required. |
