摘要:

目前,国内外的干扰试井理论已有了相当程度的发展,均质油气藏的干扰试井理论及分析方法已比较完善,双重介质油气藏干扰试井理论相对也比较完整。但是,有关复合油气藏试井的试井理论和分析方法还很少,尤其是考虑井储和表皮的复合油气藏试井理论更少。因此,提出了考虑井筒储集和表皮系数影响的复合油藏试井模型,并利用拉氏变换进行了求解,制作了相应的样版曲线。

关键词: 井储, 表皮, 复合油藏, 干扰试井, 拉氏变换, 数值反演

Abstract:

The interference well testing theory has been developed in some degree, the theory and analysis method in hoeoerasedso well, and the theory in dual porosity reservoir has been relatively perfect. But, the theory and analysis method of interference well testing in composite reservoir is developing slowly, especially considering wellbore storage and skin factor. So the paper put forward considering the composite reservoir well testing model considering wellbore storage and skin factor, the model with the Laplace transfer was solved, and the corresponding type curve was plotted.

Key words: wellbore storage, skin effect, composite reservoir, interference well testing, Laplace transformation, numerical inversion
