| 摘 要： | 欠平衡钻井作为一项为油气田勘探开发服务的新技术,其核心就是对井底压力的控制,井底压力控制监测是国内外都在不断改进和发展的重要研究方向。本文提出了通过优化综合录井仪实现对欠平衡钻井井底压力的实时控制监测,并形成了一套与之相适应的软件.该系统适用于在液相(自然和充气)欠平衡钻井过程中进行压力监测分析,可用于直井、定向井和水平井欠平衡钻井过程分析。

| Abstract: | Underbalanced drilling as a new technologies for the service of oil and gas exploration development, the core is control for the pressure of bottom hole, bottom hole pressure control and monitoring is a important research direction that constantly improving and devel- oping at home and abroad, In this paper, by optimizing the compre- hensive logging instrument to achieve underbalanced drilling bottom- hole pressure on the real-time control monitoring, and formed a set in the corresponding software. The system is carried out the pres- sure monitoring and analysis in the underbalanced drilling of liquid phase （natural and inflatable）, can be used for underbalanced drilling process analysis in vertical wells, directional wells and horizontal wells. |
