  • Arrangement for patching off troublesome zones in a well
    Patent number: 5083608
    Abstract: The arrangement for patching off troublesome zones in a well has a string of profile pipes with cylindrical portions at their ends, and a device for setting the string of profile pipes in a well, mounted for longitudinal reciprocation inside the string of profile pipes.Said device includes a reamer of the cylindrical portions of the profile pipes, positioned inside the uppermost cylindrical portion of the string of profile pipes, rigidly connected with an expander positioned above the string of profile pipes and having a housing with expanding elements mounted thereon.

  • Method of construction of multiple-string wells
    Patent number: 4976322
    Abstract: The method of well construction includes the steps of drilling the rock and consolidating it with a conductor casing, a surface casing string and a flow string, and isolating the troublesome zones of the well with profile pipes being reamed in the course of their setting. The reaming of the profile pipes is effected by building up a pressure drop across them and subsequently expanding them. The drilling of the rock after the casing-in of the well with the conductor casing and the surface casing string is preformed with a bit of one and the same diameter, with the troublesome zones being reamed to a diameter equalling the outer diameter of the reamed profile pipes which are successively set in all the troublesome zones of the well as they are exposed by the drilling.
