摘要： A stabilizer body is rotatably carried by the stabilizer sub, wherein the stabilizer body remains substantially stationary relative to the borehole as the drillstring rotates. At least one stabilizer blade is carried by the stabilizer body, the stabilizer blade being radially extendable from the stabilizer body and into engagement with the sidewall of the borehole. Each stabilizer blade is extendable and retractable from the stabilizer body independently of the others.

摘要： A drillstring carries a stabilizer sub above the drill bit for steering or directing drilling. The stabilizer body is rotatably carried by the stabilizer sub, wherein the stabilizer body remains substantially stationary relative to the borehole as the drillstring rotates. At least one stabilizer blade is carried by the stabilizer body, the stabilizer blade being radially extendable from the stabilizer body and into engagement with the sidewall of the borehole. Each stabilizer blade is extendable and retractable from the stabilizer body independently of the others. The stabilizer blades are coupled to the stabilizer body such that the blades are capable of collapse to minimum radial extension if the stabilizer assembly becomes stuck in the borehole.

摘要： A drillstring terminating in a drill bit is run into a borehole. A reduced solid content drilling fluid is pumped through the drillstring and out the bit, wherein the drilling fluid impinges upon and disintegrates formation material in cooperation with the bit. An annulus fluid having a density greater than that of the drilling fluid is continuously pumped into the annulus between the borehole and drillstring, wherein the annulus fluid extends substantially from the surface to the bottom of the drillstring. Drilling fluid and cuttings resulting from disintegration of formation material are returned to the surface through a substantially unobstructed tubular passage in the drillstring. The annulus fluid is maintained under a selected and controlled pressure in the annulus, wherein an interface is formed at the drill bit at which annulus fluid mixes with the drilling fluid and is returned along with the drilling fluid and cuttings and drilling fluid is substantially prevented from entering the annulus.

摘要： A stabilizer body is rotatably carried by the stabilizer sub (3), wherein the stabilizer body remains substantially stationary relative to the borehole as the drillstring rotates. At least one stabilizer blade (11) is carried by the stabilizer body, the stabilizer blade being radially extendable from the stabilizer body and into engagement with the sidewall of the borehole. Each stabilizer blade is extendable and retractable from the stabilizer body independently of the others. Each of the blades is guided in slots (17) with inclined bottom (17A) and shifted along the bottom by an electrical motor (19). The motors are fed by batteries (25) which are charged by inductive coupling with charging coils (27) carried by stabiliser sub (3). The movement of the blades is controlled either via telemetry from the surface or by MWD system.

摘要： A drillstring terminating in an drill bit (3) is run into a borehole. A redu ced solid content drilling fluid is pumped through the drillstring tubes and out the bit, wherein the d rilling fluid impinges upon and disintegrates formation material in cooperation with the bit. An annulus flu id having a density greater than that of the drilling fluid is continuously pumped into the annulus (5) betwe en the borehole and the drillstring, wherein the annulus fluid extends substantially from the surface to the bott om of the drillstring. Drilling fluid and cuttings resulting from disintegration of formation material are r eturned to the surface through a substantially unobstructed tubular passage (17) in the drillstring. The an nulus fluid is maintained under a selected and controlled pressure in the annulus, wherein an interface is f ormed at the drill bit at which annulus fluid mixes with the drilling fluid and is returned along with the d rilling fluid and cuttings, and drilling fluid is substantially prevented from entering the annulus.
