| 摘 要： | 对于纯气井压力恢复试井 ,井口压力与井底压力存在一定的关系。通过对两口井实测压力资料的分析表明 ,井口压力恢复曲线与井底压力恢复曲线近似平行 ,只是井口测压数据出现径向流时间略迟于井底。利用井口压力资料绘制各种曲线 ,可以粗略诊断其井底流动状态 ,实现对整个测试过程进行监测

| Abstract: | For pressure build-up test of a pure gas well,it exists a certain relationship between wellhead pressure and bottomhole pressure. Analysis of actual pressure data from two wells indicates that it exists an approximate parallelrelationship, only radial flow of bottom hole pressure appears earlier than that of wellhead pressure data.Therefore wellhead pressure data can be used to draw different kinds of curves,roughly diagnose its bottom holeflow state in order to monitor the whole test process. |
