摘要

"Methods to control pressures during drilling operations in a submarine ground training.And to maintain pressure control of the well during drilling operations in an environment of underwater drilling ".A method to deal with the problem known as breathing training,That occurs during the drilling of a well sub in a formation of earth to carry out a series of leak testing to determine the pressure of the propagation of fracture in the formation of the earth and theThe pressure of reopening of fracture in the formation of the earth and maintaining the hydrostatic pressure in the formation of earth, in a range between the reopening pressure and the pressure of fracture propagation of the fracture.
