摘要
本文从理论上分析了不同产量序列对修正等时试井计算结果产生的误差。指出对于修正等时试井，首先其产量序列必须采用递增的方式；其次，为了使误差保持最小，其产量序列要有较大的比值。本文的研究，为修正等时试井设计提供了充分的依据，从而使修正等时试井得到更有效的应用。
It is found that difference flow rates sequence has a large effect on calculation result of modified isochronal well tests when we analyze testing data of the central gas field in Shan-Gan-Ning basin. In this paper we discuss theoretically the error from different flow rates sequence in calculation result of modified isochronal testing, from which we obtain the following conclusions: ① The flow rates sequence of modified isochronal testing of gas well must apply an increasing form. ② The flow rates sequence must have a large ratio enough to minimize the calculation error. The study of this paper provides sufficient evidences for the design of modified isochronal testing and makes its application more effective.
