Because of the low penetration rate and loss of fault in block 32 and 53 in YEMEN, the problem of loss was successfully salved by adopting the foam drilling fluid and accelerated the drilling speed in hard formation by applying the air hammer.

也门32区块和53区块地层可钻性差、存在断层漏失，采用泡沫钻井液有效地解决了井漏问题，应用空气锤钻井加快了硬地层的钻进速度；

The practice demonstrated that to use the foam drilling will raise drilling efficiency 31.7% and net drilling time availability 3.4%, reduce aggregate cost 56.1% than conventional mud drilling.

实践证明，采用泡沫钻进要比常规泥浆钻进钻效提高31.7%，纯钻时间利用率提高3.4%，综合成本降低56.1%。
