在疑难井或水平井测井过程中,由于井内情况往往会出现测井仪器在井内被卡的现象,如果强行上提会造成测井仪器落井摔坏和测井数据的丢失,所以在此类情况下会采取先压井,然后通过反穿芯打捞法提出井内仪器,从而防止了测井资料的丢失,但在反穿芯打捞作业过程中井内有可能发生溢流现象,本文从这个现象研究,从而研究出一套发生溢流后既能有效的防止井喷事故的发生,又能不剁断测井电缆的工具,使反穿芯打捞电缆作业在保证施工安全的前提下进行。
In a well logging or horizontal well logging process, logging tools are often stuck in the well due to the in-well conditions. If the forcing can cause the logging tool to fall into the well and lose the logging data, Under the circumstance, the well will be pressured first, and then the well borehole instrument will be put forward by the anti-core-piercing method to prevent the loss of the well logging data. However, overflow phenomenon may occur in the well during the process of CFW drilling. In this paper, So as to study a set of tools that can effectively prevent the blowout accident and prevent the logging cable from being cut after the overflow occurs so as to ensure the safety of the construction.
