摘要： 低渗透油气藏存在不符合达西定律的渗流,从大量实验和产生低速非达西渗流的影响因素分析,低渗透油气藏确实存在启动压力。鉴于此,提出了准确描述含启动压力梯度非达西渗流的试井分析数学模型及模型的解,研究制作了非达西渗流的内、外边界条件下的典型样板曲线,该样板曲线对试井分析解释提供了可靠的帮助,为正确认识和研究低渗透油气藏的特殊规律提供了一个好的方法。

Abstract: There exist non Darcy's flow and starting pressure in a low permeability reservoir according to analyses of experiments and effect of low velocity non Darcy's flow. This paper proposed mathematic model for well test analysis of perfectly describing non Darcy's flow with starting pressure gradient and its solution, and offered type curve of non Darcy's flow under inner and outer boundaries. The type curve is not only helpful to well test interpretation, but also can be used as a powerful tool to correctly understand and study special law of low permeability reservoirs.

Key words: low permeability reservoir, non Darcy 's flow, mathematic model, curve, application
