Definitions

  • the invention relates to a method for producing pipes on the one hand according to the preamble of claim 1 and, on the other hand, screwable units of a drill pipe according to the preamble of claim 2.
  • Pipes for the oil and gas industry and screwable units of a drill pipe are used for drilling wells in large depths or for the transmission of oil in the surface area.
  • the pipes are mainly mechanically stressed by internal pressure and longitudinal forces, the units by the mass of the drill head, their own mass and the drilling torque and bending. For this reason, only heat-treated pipes and units are used, which are coated with so-called connectors. These are flange connectors or particularly thick-walled, short pieces of pipe with a thread, through which the units are connected to form a drill pipe.
  • the connectors were previously screwed onto the pipe ends of the units and then welded.
  • it has become common practice to weld the pipe connectors e.g. B. friction welding to connect to the tube and deburr the weld and treat by stress relief annealing.
  • Such pipes and units meet the physical properties placed on them (yield strength, elongation). In the presence of moist acid gas, they are only burdened up to a small part of their yield strength. In particular, the transition area welding to base material in pipes of previous manufacture is extremely susceptible to stress corrosion cracking. The stress corrosion cracking resistance is tested in a hydrogen sulfide-saturated test solution according to the NACE standard TM-01-77.
  • EP-A-00 64 730 discloses a process for the production of pipes for the oil industry, in particular for deep bores in which these pipes are exposed to wide temperature ranges, high pressures and corrosion, the steel and the like. Contains 0.35 to 0.9% Mn, 0.8 to 1.5% Cr, 0.15 to 0.75% Mo as well as nickel and copper. A maximum value of 0.04% is given for the sulfur content.
  • the object of the invention is to increase the corrosion resistance of the tube and the unit and to adapt it to the physical resistance.
  • Claims 1 and 2 stand side by side in that they relate to the production of different types of pipes.
  • the claim 1 relates to pipes through which hydrogen sulfide-containing oil or natural gas is mainly passed on to the surface of the earth and also units for which protection is particularly claimed according to claim 2 and which are used for the production of boreholes and which are in a so-called acid gas-rich environment under high mechanical Stress.
  • the wall thickness at the pipe ends can be thickened by axial compression in the die. The wall thickening also creates a wider welding area.
  • the connectors are generally flanges or short, very thick-walled pipe sections. The latter are twisted on one side to the wall thickness of the thickened pipe ends and prepared on the thread area. These connectors also do not need to be heat treated before welding.
  • connectors with a pre-turned external thread and with an internal thread that are press-welded in pairs at the ends of the pipe.
  • the protruding ridge is removed.
  • the pipe and connector are made of a steel composition that is not resistant to abrasive corrosion.
  • inhibitors are usually added to the drilling fluid, so that the erosive corrosion is irrelevant.
  • the steel composition is adjusted so that the wall thickness with water or oil quenching is also fully hardened to the greatest possible thicknesses on the pipe and on the connectors, ie it takes on fairly uniform hardness over the full wall thickness and thus has the same strength properties.
  • the pipe manufactured for the oil industry and the units of a drill pipe are hardened as a whole. As far as the dimensional range allows, the immersion process is used. These parts are then tempered and the heat treatment ends with cooling in air. The temperature control to be used results from the characterizing features of claim 3. Thus, the parts have a uniform structure and thus the same mechanical properties over the entire length, in particular in the welding area and the area of the base material influenced by the welding heat as well as comparable corrosion resistance.
  • An embodiment of the invention relates to a unit of a drill pipe and is based on the following steel composition (mass percent):
  • the output tubes are made from continuous cast billets by cross rolling, stretching over a cylindrical rod in the continuous rolling mill and by reducing the stretch to the final dimension of 114.3 diameter x 9.19 mm Wall thickness rolled and cooled in still air. In a renewed heating, however, only at the ends of about 300 mm in length, the wall thickness is compressed to about 22 mm with an outer diameter of about 131 mm. It is cooled again in still air.
  • the connector and the outlet pipe are connected by friction welding and deburred, as described in DE-PS 31 33 181.
  • the full length of the drill string unit is now available. So it is quench hardening and tempering a system supplied, as described in DE-PS 15 83 993. Quenching is done from a temperature of 890 ° C in oil for about 120 seconds.
  • the drill pipe unit is then laid out on a grate in still air.
  • the tempering temperature is 690 ° C. After cooling in air, straightening can be provided.
  • the drill pipe unit now has the following physical properties
