| 摘 要： | 对近两年大庆深层气井测试资料统计表明:深层气井测试初关井压力恢复曲线出现早期出现突然下降、中期恢复极为缓慢并呈直线等异常现象,这种现象不仅仅简单解释为地层原因,而是由测试工艺、测试工具等非地层因素造成。

| Abstract: | Daqing deep gas well in recent years shows the testing statistics:The beginning of deep gas well test shut-in pressure recovery curve showed a sudden decline in the early;mid-term recovery is extremely slow and linear anomalies,etc.This phenomenon is not simply to be explained as the formation reasons,and the testing process,testing tools and other non-formation factors contributed to it. |
