| 摘 要： | 针对苏里格气藏非均质性严重的实际情况，建立了既考虑表皮效应、井筒存储效应的影响，又考虑气藏地层特性及地层厚度变化的适合其气藏特征的三区不等厚横向非均质复合气藏试井解释模型，求出了无限大和封闭边界两种典型外边界条件下的气藏拟压力解，并绘制了井底压降典型曲线，就各参数对典型曲线的影响进行了分析。利用此模型对气井实际试井资料进行了解释，解释结果与实际情况相符。

| Abstract: | Aiming at serious heterogeneity of Sulige Gas Reservoir,this paper constructs a well testing interpretation model for lateral heterogeneous composite gas reservoirs.This model considers not only effect of skin effect and well bore storage effect,but also geologic characteristics and formation thickness change of gas reservoirs.It calculates pseudopressure in two typical conditions of infinite great and closed boundary,plots typical curve of bottom hole pressure drop,and analyzes the typical curve of each parameter.It interprets actual well testing data of gas wells using this model,and interpretation result is in accordance with actual status. |
