呼图壁储气库试井资料解释方法探讨

Discussed on Well Testing Data Interpretation Method to Hutubi Gas Storage

呼图壁储气库测试资料受井间、边界以及其它因素干扰较为普遍,变井储和边界干扰问题突出。常规试井解释软件无法准确利用不稳定试井模型解释出准确的地层压力及储层渗流参数,测试时由于单井间压力差异大,部分井也出现压力上升的异常现象,不稳定试井解释困难。现研究了储气库试井资料的特点和规律,分析了目前呼图壁储气库试井资料解释中存在的问题,尝试利用Swift试井解释软件平台解释了部分存在干扰影响的实例井。与其它试井解释软件相比,Swift试井解释软件平台在呼图壁储气库资料解释中具有更好的适用性,能够有效地解决压力及其导数曲线末端严重上翘或下坠的资料解释问题。

Test data of the Hutubi gas storage is interfered by cross-hole,boundaries,and other common factors popularly,problems of changing well storage and boundary interference are prominent. Because of the large pressure difference between single well,abnormal phenomena of pressure rise in part of wells,being difficult by unstable well test interpretation,conventional well test interpretation software can't accurately use unstable well test model to explain the accurate formation pressure and reservoir seepage parameters. Through research on regularity and characteristics of well test data to gas storage,and analysis of the current problems in well test interpretation,try to take advantage of Swift well testing interpretation software platform explains parts of actual well existing the interference effects. Compared with other well test interpretation software,Swift well testing interpretation software platform has better applicability in data interpretation to Hutubi gas storage,which can effectively solve the data interpretation problems of the pressure and its derivative curve serious puffed up or down at the end.
