摘要： The bottom hole assembly of the present invention includes a drill bit driven by a positive displacement drilling motor, the motor being constructed of tubular housings, one of said housings having a bend so as to cause the bit to drill directionally, another housing containing a rotor and stator to generate power, and a flexible section between the power generation housing and the bend. A stabilizer is disposed on one end of the flexible section for engaging the wall of the borehole and the housing with the bend includes a wear pad for engaging the lower side of the borehole. The bottom hole assembly contacts the borehole at three contact points, namely at the stabilizer, the wear pad, and the drill bit, for producing the necessary build-up rate, along with the bend, and thus the curvature of the borehole being drilled. The flexible section has a stiffness which is less than the stiffness of the housing of the stator and has a stiffness which is on the order of 33% or less of that of the power generation housing. The stiffness is determined by the selection of the material, wall thickness and length of the flexible section such that the desired flexibility is achieved, but the necessary torsional strength and axial load capabilities are maintained. The purpose of the flexible section is to allow the bottom hole assembly to be configured to achieve high build rates, on the order of 20 to 70 degrees per hundred feet, without generating excessively high loads and stresses on the bit and other bottom hole assembly components.

摘要： A method for reducing a skin effect in a downhole environment is provided, including the step of radiating vibrational waves at a wellbore wall such that the vibrational waves have at least one direction of greatest vibrational energy transfer directed toward the wall, thereby reducing the skin effect. An apparatus for reducing a skin effect in a downhole environment is also provided. The apparatus includes at least one vibrational wave source having at least one direction of greatest vibrational energy transfer, and a means for positioning the vibrational wave source proximate a wellbore wall.

摘要： A steering assembly includes upper and lower tubular housings connected by a universal joint. An angle cam is disposed on the end of the lower housing and projects into the upper housing. A plurality of wedge members extend axially from the upper housing and into engagement with the angle cam. Drive trains are connected to the wedge members to move the wedge members toward and away from the angle cam so as to pivot the lower housing at the universal joint and change the angle and azimuth of the lower housing with respect to the upper housing. The lower housing is connected to a bearing pack supporting a drill bit such that upon changing the angle and azimuth of the lower housing, the direction of the drilling of the drill bit is also changed. The steering assembly being connected to composite tubing having conductors in the wall thereof for conducting data and commands between the steering assembly and a processor at the surface and for providing power to the steering assembly. Data on the position of the bit is transmitted to a processor which determines the direction of drilling and selectively transmits commands to the steering assembly to change the bend angle and direction of the drilling of the bit.
