    摘要： Apparatus and methods are provided for reducing drilling vibration during drilling with casing. In one embodiment, an apparatus for reducing vibration of a rotating casing includes a tubular body disposed concentrically around the casing, wherein tubular body is movable relative to the casing. Preferably, a portion of the tubular body comprises a friction reducing material. In operation, the tubular body comes into contact with the existing casing or the wellbore instead of the rotating casing. Because the tubular body is freely movable relative to the rotating casing, the rotating casing may continuously rotate even though the tubular body is frictionally in contact with the existing casing.

    摘要： Methods and apparatus are provided to place a conductor pipe and a casing in a subsea environment. In one embodiment, a conductor pipe is jetted or drilled into the subsea floor. Thereafter, a casing drilling assembly comprising a drill casing and a drilling assembly is connected to the drill pipe using a crossover. The drilling assembly urged into the seafloor until a casing latch on the drilling assembly is engaged with a casing profile of the conductor pipe. During drilling, instrumentation in the drilling assembly may be used to measure geophysical data. The measured data may be used to optimize the drilling process. After the drill casing is engaged with the conductor pipe, cementing may be performed to set the drill casing.

    摘要： In one embodiment, a method of forming a wellbore includes running a liner drilling assembly into the wellbore, the liner drilling assembly having a liner, a conveying member, one or more connection members, and a drilling member. The method includes temporarily suspending the liner at a location below the rig floor; releasing the conveying member and the drilling member from the liner; re-connecting the conveying member to the liner; releasing the liner from its location of temporary suspension; and advancing the liner drilling assembly.

    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.
