| 摘 要： | 针对文23气田供气紧张无法关井进行压力恢复试井的问题，运用不稳定渗流理论，引入了二流量不停产试井工艺方法。2000-2003年共三次对37口井进行了二流量试井，应用结果表明求解出的地层压力误差小于3％，渗透率和表皮系数在地质要求的允许误差范围内，基本达到与关井压力恢复试井等效的结果。该工艺为文23气田的开发调整、措施增产提供了有力的理论依据。 |

| Abstract: | Because of tight gas supply, the wells in Wen23 gas field can not shutdown to cany on pressure build-up well test. Based on the theory of unstable percolation flow the technology of two-flowrate well test is introduced. It is applied in 37 wells for 3 times from 2000 to 2003. The result indicates that the error of formation pressure is less than 3 % , the permeability and the skin factor are in the permissive range of geology requirement. Its result nearly equals to the one of the shut-in pressure build-up well test. The technology provided effective theoretical foundation for development adjustment and stimulation. |
| Keywords: | two-flowrate well test continue production geological information of gas reservoir tight gas supply Wen23 gas field |
