摘要(Abstract)：
本文论述了一种简便易行的非自喷井DST流动期或段塞流压力历史分析新方法(?)FMRH法(Flow Period Maximum Rate Horner Method,流动期最大产量Horner分析方法)。方法基于Jones等人推出的常产量压降试井分析的理论结论,结合DST不同于常产量压降试井的生产特点,将DST流动期视为压力恢复的续流期,以流动期的初始产量为常产量进行分析。对实际资料的处理表明,新方法的应用不仅能提高分析效率,而且将提高分析结果的正确性。
This paper presents a new convenient method for interpreting
the DST flow period or slug flow pressure history-FMRH (Flow Period
Maximum Rate Horner) method. On the basis of the conclusion for constant rate well test analysis derived by Jones(1) et al., combined with the production characteristics of DST which is different to the constant rate well test, the method takes the DST flow period as the afterflow of the build-up, with the maximum rate of the flow period being the constant-rate. The proccessed data show that the application of the method not only increased the speed of analysis but also improves the accuracy of the analysis result.
