20090008087 | THREADED JOINT FOR AN OIL-WELL TUBING - The engineering problem of the claimed invention consists in the increase of operating reliability of the threaded joint, whose coupling has the coating applied by the diffusion galvanizing method, by way of ensuring a proper standard tightness. The technical result of the increase of the inlet cylindrical counterbore length in the internally threaded element by the value of the thread tightness increment caused by galvanizing and determined from the claimed empirical formula consists in increased reliability of the joint under service conditions as the probability of overtightening the joint for the sake of attaining the nominal tightness, as well as damage to the end thread turns projected from the coupling on service are ruled out. This result is attained without consumption of time and funds for re-training of the personnel, publication and delivery of new normative materials to each drilling site, manufacture of new calibrating tools and repair mountings. In its turn, this makes it possible to immediately begin supplying the suggested joints and increase the service life of standard threaded joints of oil-well tubings from 6÷8 to at least 50 screwing/unscrewing cycles. Besides, in case of forced screwing with a standard torque the joint reliability also increases because the threaded part of the externally threaded element is nearly completely hidden inside the counterbore due to the increased counterbore length and thus protected against the mechanical effect of the well medium. | 01-08-2009 |
20090021008 | DRILL PIPE WITH TOOL JOINTS - The engineering problem of the claimed invention is to enhance wear-resistance of drill pipe tool joints. The proposed drill pipe consists of a body with upset ends and tool joints connected by means of friction welding, having tapered thread and a double coating, the first layer being applied by means of thermo-diffusion zincing and the second one, by means phosphate treatment. Enhancement of tool joint life, as compared to the tool joints with phosphate coating only, allows no overdimension to be stipulated for future repair purposes, which saves up to several kilos of metal per tool joint, decreasing the drill string weight by several tons. With a view to increasing the joints' durability and reliability of welding seams the thickness δ of the first coating layer as function of thread conicity K is adjusted according to the following formula: δ=0.09 . . . 0.13 K. The segment at 15 to 25 mm from the welding spot on joints is coated with phosphate only. | 01-22-2009 |
