凝析气在垂直裂缝地层中的三线性渗流模型

A condensate gas model of three linear filtering in vertical fractured reservoir and it's applications

针对低渗凝析气藏的人工压裂井渗流问题 ,建立了凝析油 -气在垂直裂缝地层中的三线性渗流模型 ,并求出这一问题的解 ,绘制了试井理论曲线 .通过实测资料的解释可计算出地层渗透率、裂缝半长、裂缝导流能力、井筒储存系数等 。

For filtering problem of hydro-fracturing well in low permea bility condensate gas reservoir, the model of three linear filtering has been bu ilt in the vertically fractured reservoir. Further, the solutions of equations h ave been found, and the test well theoretical curves are drawn by the solutions. Using interpretation practical measure dada of the well test, we may calculate the formation permeability, fracture half length, fracture conductivity, fractur e skin and well-bore storage coefficient etc. Lastly, an applicative example has been given in buildup test well analysis.
