摘要
例举几种异常压力恢复曲线形态 ,分析了产生异常的可能原因为 :封隔器卸压 ;地层污染或工具堵塞 ;地层欠压 ;地层物性极差 ;邻井影响等。对正确认识测试信息 ,准确评价油气层提供了有力帮助。
In this paper, several curve shapes of abnormal pressure build-up are listed and possible causes are analyzed. The causes are presented as follows: packer unloading pressure, formation damage, oil tool plugging, formation voidage, the worst formation physical properties and the effect from vicinage wells.The paper presents powerful help to exactly understand information from testing and to nicely evaluate oil and gas formations.
