摘要
气基流体天然气钻井技术是在空气钻井技术的基础上,为适应地质条件和工程要求而发展起来的。该技术在川渝地区、长庆油田等天然气气田进行了应用并取得了宝贵经验。气基流体天然气可以在产层井段和含有天然气的油气井中应用,能够在提高钻速的同时有效地防止井下燃爆等复杂问题的发生。通过大量实例介绍,阐明了气基流体天然气作为钻井循环流体在保护产层、防止井下燃爆等方面的突出优点。
Natural gas as the base fluid in gas drilling had been widely used in Chuanyu and Changqing area and experiences and expertise were obtained.Rate of penetration can be increased greatly with the use of natural gas drilling fluid,and downhole explosion can to some extent be prevented.This paper listed series of examples to illustrate the benefit that can be obtained from the use of natural gas drilling fluid.
