摘要
脉冲试井用来确定油藏的传导系数和储存能力,通过改变激动并(脉冲井)的产量并在附近观察井(响应井)上观察压力响应来进行脉冲试井。 本文给出考虑井筒储存和井壁的表皮效应的脉冲试井理论模型。以往研究多采用切线法,这种方法局限性很大,常给解释结果带来误差。本文引入割线法,可以在压力曲线的任一位置做平行线时,明显提高了解释精度。
A pulse test may be used to determine the reservoir transmissivity and storage capacity. The puls test may be performed by changing the production of a pulsing well and observing the pressure response of a nearby rcsponsing well.The paper deals with the model of a pulsing theory considering wellbore storage and wall skin effect. The tengential method, which is of great limitation and always brings about interpretation errors, was employed in the previous studies. In the present paper, a secant method is introduced. With this method, a pair of parallel lines may be made of any point on a pressure curve. The exactness of interpretation may be increased obviously.
