  • Publication number: 20030075341
    Abstract: The invention relates to the oil industry and can be used for increasing well productivity by increasing the oil flowrate, for a well workover and isolation of a water-encroached bench. The inventive packer (1) comprises a body (4) provided with a scaling ring (5) which is collapsible in a radial direction and fitted with a drive. Said drive is embodied in the form of a chamber (6) containing a working medium in an such initial aggregative state in which it occupies a minimum volume, and comprises an element transferring the working medium from the initial state to another state. In order to fix the packer (1) in the well, the working medium of the drive of the sealing ring is transferred from the initial aggregative state to another state, where the working medium occupies a greater volume.

  • Publication number: 20020157831
    Abstract: The proposed method for processing the productive formation in a bottom-hole zone of a well (1) comprises heating the liquid in the bottom-hole zone of a well (1) and removing clogging products therefrom. In accordance with the technical solution, the upper part of the bottom-hole zone of the well (1) is sealed before heating the liquid, thus forming a bottom-hole chamber (6), and after the heating, the liquid within the volume of the bottom-hole chamber (6) is cooled and then this chamber (6) is unsealed before removing the clogging products therefrom.

  • Patent number: 4121672
    Abstract: The device has a hollow cylindrical housing pointed at the front end and accommodating a hammer piston, which defines with the housing a front end work chamber and, which has at a rear end portion a cylindrical space and an open-ended radial passage. The cylindrical space receives the large portion of a stepped pipe in order to define with the hammer piston a rear end work chamber. The small portion of the pipe is received in the rear end portion of the housing for rotation about its axis within limits defined by a locking member and is connected, by means of a flexible hose, to a source of compressed air for permanent supply to the rear end work chamber of compressed air. The large portion of the stepped pipe opens the radial passage of the hammer piston at regular intervals to establish communication between the front end work chamber and the rear end work chamber, thereby enabling forward movement of the device.

  • Patent number: 4114700
    Abstract: The apparatus has a pointed-nose hollow cylindrical body with a closed rear portion. Disposed inside the body, so as to enable reciprocation and rotation about the axis of the body, is a stepped striker which can be locked against rotation about the axis of the body in two positions, the positions corresponding to forward and reverse movement of the apparatus.For the purpose of admitting compressed air into a forward working chamber, the striker is provided with a central passage permanently connected to a rear working chamber and at least two radial passages which provide communication between the central passage and an outer cylindrical surface of a large step of the striker. The radial passages are displaced relative to each other both circumferentially and longitudinally along the axis of the body.

  • Patent number: 4070948
    Abstract: The present invention relates to pneumatic impact devices and can be used to the best advantage for making holes in compacted soils.The device is provided with a hollow casing which accommodates a stepped ram with the maximum-diameter step in its front part. This step has longitudinal channels which open at one end into a working chamber defined by the maximum-diameter step and the side walls of the casing and serving for receiving compressed air from the compressed air line, with the air moving the striker to impart a blow after which it is discharged through holes in the casing.

  • Patent number: 4063423
    Abstract: Method consisting in forming a borehole in the ground preferably having a diameter smaller than the desired diameter of a pile, compacting a concrete mix poured into the borehole by repeatedly passing a pneumatic mole through the borehole filled with concrete to compact the concrete mix in the peripheral zone of the borehole thereby concurrently expanding the reinforcement.

  • Patent number: 3995702
    Abstract: A device has a cylindrical housing with a pointed front portion, which accommodates a striker separating the inner space of the housing to form a front and rear active chambers. The striker is provided with an open space at the rear end face thereof which mounts an air distributing branch connection threaded in the housing to be axially displaceable therein for reversing the device motion and adapted to admit compressed air to the active chambers and discharge it to the atmosphere therefrom thus reciprocating the striker which applies impacts to the housing. The air distributing branch connection has pipes arranged coaxially and forming longitudinal passages, of which the central passage serves to admit compressed air to the active chambers, while the annular passage between the pipes is used to discharge spent air from the active chambers.

  • Patent number: 3955631
    Abstract: The present sampler is adapted to take soil samples from the ground surface, from a borehole sunk by other tools, as well as for drilling shallow boreholes. The sampler is provided with an air-operated percussion mechanism and a soil sample receiving sleeve arranged coaxially thereto. The side surface of the sleeve is provided with an annular ridge having a diameter somewhat larger than the diameter of the percussion mechanism housing. This feature enables a reduction of the forces applied to the sampler to sink it into or withdraw it from the soil.

  • Patent number: 3952813
    Abstract: A percussive device comprising a housing with a pointed front end and a hammer piston accommodated in the housing to form a front working chamber therewith. The hammer piston is provided, in the rear portion thereof, with a cavity in permanent communication with a source of compressed air, the cavity serving as a rear working chamber. An airdistribution mechanism includes a tube mounted in the housing within the hammer piston cavity so that it is conjugated with the walls of the cavity, the piston having air passages therein positioned in such a manner that, during the reciprocation, the tube alternately communicates the front working chamber, via these passages, with either the rear working chamber or ambient atmosphere.
