| The present invention relates to a flange fastening apparatus for drilling riser, which is capable of fastening flanges of pipes composing a drilling riser to be connected to each other. The flange fastening apparatus for drilling riser comprises: an engaging ring separably fitting on a first pipe among pipes and coupled to the first pipe to move along the longitudinal direction of the first pipe; rotating arms each having one end coupled to the engaging ring by a hinge and the other end pivoted around a hinge shaft, and provided along the circumferential direction of the engaging ring; fixing bolts detachably coupled to the other end of each of the rotating arms, respectively, to be integrated with the rotating arms and passing through the flanges according to the movement of the engaging ring or by the pivoting of the rotating arms; fastening nuts fastened to the fixing bolts to press and fixing the flanges; and a bolt fastener for preventing the fixing bolts from being separated from the flanges while suppressing the dehiscence of the fixing bolts or binding the fastening nuts and the fixing bolts. Thus, as the fixing bolts are coupled to the engaging ring through the rotating arms to be pivoted while moving together, the fixing bolts can be fitted to the flanges together, thereby shortening a fastening time. Particularly, the fixing bolts and the fastening nuts can be restricted by the bolt fastener, thereby maintaining the clamping force of the fixing bolts or the fastening nuts even if a repeated impact such as ocean currents is applied. | ||||||

| A bore hole is formed using an elongated, reversible rolling tube with inner and outer walls connected at the forward end by a rollover area, holding a central pipe. The area is positioned so ti projects into an underground formation, and drilling fluid is directed through the annulus between the inner wall and the pipe and then through the pipe. Driving fluid is directed through the annular space between the walls, so that the inner wall moves through the area to become the outer wall as the tube moves forward into the slurry of cuttings as the pipe is carried forward as a function of the movement of the area. The tube is e.g. of woven cloth, and the fluid may include a hot acid or basic aqueous or petroleum-based solution. | ||||||

| Adjustable drill string housings are described for use in the directional drilling of wellbores, e.g. wellbores for hydrocarbon recovery wells. The adjustable drill string housings permit adjustment of a bend angle in the housings without removing the housings from a wellbore. In some exemplary embodiments, the bend angle can be adjusted by changing the internal stresses in a support member carried by the housings. In other embodiments, the bend angle may be adjusted by causing failure of sacrificial support members carried by the housings, and the failure may be caused by delivering chemicals through a chemical delivery system to the sacrificial support members. Methods of operating the adjustable drill string housings include multi-lateral drilling operations wherein the bend angle is adjusted when a casing window has been detected. | ||||||
