【Abstract】 Based on the merit of foam, a new drilling method is put forward, that is the foam drilling technique of deep well applied in drought and scarce water areas. Boring technology for each segment of deep well is provided. The foam grouting system and the foam drilling technology are specially discussed on their main equipment and the parameters in the paper. It is indicated that the application of the technique can solve the problem of drilling the well of 500～800 meters in the drought and scarce water areas更多还原
