【摘要】 本文主要介绍了采用双对数曲线和单对数曲线分析压力恢复曲线的方法,并着重整理和分析了濮城油气田压力恢复曲线的类型。这些类型包括:线型或续流直线型;断层遮挡型;边界或多井干扰型;驼峰型和多层双直线型等。我们认为,在压力恢复曲线分析中,采用有效的方法,研究其类型特征,对于正确地分析油气井产状和确定地层参数都是有益的。更多还原

【Abstract】 This paper summarizes a technique of using semi-log and log-log graph in pressure build-up analysis,and presents five types of build-tip curves of Pucheng oil and gas field in central China,straight-line or straight-line with wellbore storage effects,affected by fault,affected by well interference, humping,effects of two or more-layers in the reservoir,etc.It is beneficial in the analysis of oil or gas well productivity and in the determination of reservoir engineering parameters when effective techniques are used and the characteristies of the types of curves are studied.更多还原
