DRILLING MACHINE AND PROCESS FOR THE CONSTRUCTION OF WATER WELLS THROUGH THE ROTARY AIR FLUID INJECTION PROCESS AND REVERSE FLUID CIRCULATION NAMED AS BACK FLOODED OR BF.

摘要

The present disclosure is related to a drilling machine and process for the construction of water wells through the rotary air fluid injection process and reverse fluid circulation named as back flooded or BF, which unites two processes into one in order to save time and costs. The usefulness of this system used for drilling large diameter water wells, is the dynamism of its operation, which can be done in a reduced time, also reducing fuel and additives consumption.
