BK9井为塔河油田外围区块的一口开发井,在连续油管气举诱喷过程中供液不足,需要下压力计测取液面恢复速度指导后期气举施工。该井远离塔河基地,安排试井车进行试井作业,延误时效,且路途费用高,同时该区块压力系数高(地层压力系数为1.97),施工作业井控风险大。通过技术创新,形成了连续油管+电子压力计动态测压工艺,开发了探液面数据校正公式,推出了塔河油田一种新的动态测压工艺。

Well BK9 is a development well located in the outer blocks of the Tahe Oil Field.gas pumping to drive oil flow in coiled tubing,liquid supply is not enough.Manometer is Whenused touslngmea5ureliquid surface restoration speed so as to guide latter gas pumping.The well is far away from the oilfield base,the regionSO It COStSis high(1.moretime and money to arrange well test.Meanwhile,the pressure coefficient of97 for formation pressure coefficient),resulting in big risks for well controls.Through techniqueelectric manometerInnovationa dynamic pressure measuring technique combining coiled tubing andis proposed.The detected liquid depth correction formula is put forward.
