Abstract

Abstract: A foam pressure increasing device was used to increase the secondary air and foam agent mixture pressure by using a dual action pump. The BWZ-1200 foam increasing pressure device was applied in the geothermal well exploration under 1 000 meters deep in Beijing, to solve the mud lost and well wash problem during drilling. The BWZ-1100 device was also applied in the mountain and dry areas of Ningxia to solve the mud lost during water well drilling, resulted in a good social and economical benefits. The device has a good prospect in drilling deep geothermal wells, water wells, oil and gas wells by combining the air-left reverse circulation drilling technique.

Key words: foam, pump, increasing pressure, geothermal well, water well, drilling
