在试井压力恢复曲线分析中,霍纳(Horner)法是目前国内外常用的方法。本文以渤中13—1、渤中13-11两口井的实例,介绍了用压降标准曲线拟合法求取K(渗透率)、S(表皮效应)值的过程,并用Agarwal等人的标准图版对S值进行了验证,所得的结果和实际地质情况是相符的,而且3种方法取得了几乎一致的结论。 Horner method is a commonly used method at home and abroad in the well testing pressure recovery curve analysis. In this paper, taking Bozhong 13-1 and Bozhong 13-11 as examples, the process of obtaining K (permeability) and S (epidermal effect) by using pressure drop standard curve fitting method is introduced and compared with the standard of Agarwal et al. Plate validation of the S value, the results obtained and the actual geological conditions are consistent, and the three methods have achieved almost the same conclusion.
