To avoid loss of drilling tools and even well abandonment due to downhole fire or explosion during air drilling in pay zones, we developed a novel downhole fire or explosion prevention sub, a kind of downhole tool made of low melting-point alloy, designed to shield off oxygen so as to put out fires. This sub is connected to the upper part of dill bit.

为了解决空气钻井在钻遇油气层时，发生井下燃爆，造成埋钻具、井眼报废等复杂情况，基于阻断氧气使火熄灭的思路研制出了一种低熔点合金制造的井下工具－空气钻井燃爆灭火阀。
