摘要
A method of drilling a well having a first tubular member extending from the surface of the well to a position proximate the bottom of the well. The first tubular member has an inner annulus therethrough. A fluid is pumped into the well through the inner annulus of the first tubular member to flush drilling cuttings out of the well. A fluid is also injected into the well, exterior to the inner annulus, to control the bottom hole circulating pressure in the well.
