【摘要】 注蒸汽井压力降落试并是确定蒸汽波及体积和了解波及区流动情况的一种经济、有效的方法。但目前我国对热采试并解释方法和软件的研究还不够完善。根据注蒸汽井试并的特点，对注蒸汽井压力数据进行积分处理，在确定注入流量时考虑蒸汽干度的影响，并给出解释时确定蒸汽区近似压力的方法，及在此饱和压力下，计算相关地层参数的公式，列出了解释方法的详细步骤。根据此方法，开发出一套注蒸汽并试井解释软件。通过对1口实例井的解释，验证了解释方法和软件的实用性。更多还原

【Abstract】 Pressure transient test in steam injection well is an inexpensive and effective means to determine swept volume and flowing condition of the steam zone. The method and the software for interpreting thermal well test data are not well studied in China. In this paper, according to characteristics of well test in stream injection well, integration of the noisy data is made and the influence of steam quality on injection rate is studied. Method for determination of pressure in the swept zone, equations for calculating related formation parameters and detailed analyzing steps are also presented. A field example analyzed by our sPecial designed software is glven to illustrate the use of the method.更多还原
