大庆深层气井试气油嘴的选择与产量预测

Optimum Choke Size Determination and Production Rate Prediction in Gas Well Test for Deep Reservoirs

利用一口气井已测得的一试气制度的试气资料,采用节点分析方法,应用WTES现代试井软件进行敏感参数分析,选择该井下一制度试气油嘴直径或对该井系统试气时油嘴大小进行选择,同时预测对应油嘴下的产能,为试气生产组织提供了依据,提高了气井试气的一次成功率和试气资料质量。

Determining optimum choke size for the next step in gas well test or optimum choke sizes for systematic gas well test,and predicting the production rates under different choke sizes by sensible parameter analysis,i.e.by analyzing the acquired test data of a single choke,node analysis method with WTES(modern well test interpretation software),provides helpful information about well test arrangement and so improves the one-operation success ratio and the quality of well test data.
