Definitions

  • the channels of the sleeve and the body are periodically closed and opened at a certain frequency.
  • the periodic covering of the channels in the zone near the borehole generates hydrodynamic fluid pressure pulses.
  • the amplitude and frequency hydrodynamic impulses depend on the pressure of the flushed fluid and the frequency of rotation of the sleeve around the body.
  • the invention has for its object to perform the assembly for generating hydrodynamic waves of the device for cleaning the borehole zone in such a way that by generating and utilizing a high wave energy directed effect of the hydrodynamic waves generated by a turbulent flow of the liquid with a wide frequency spectrum in the zone near the borehole and by generating a negative pressure in it, a high effectiveness of the cleaning of the zone near the borehole, an increase in the productivity of a borehole and the oil release of a layer are guaranteed.
  • the design of the assembly for generating hydrodynamic waves in the form of a swirl chamber with the tangentially arranged inlet channels makes it possible to generate hydroacoustic waves with a wide frequency spectrum for acting on a productive layer.
  • the use of the swirl chamber allows a vacuum zone, i.e. a depression to create in the borehole zone. All of this greatly improves the cleaning of the pore channels and increases the oil flow to the well.
  • the narrowing of the outlet channel of the swirl chamber is due to the fact that, as the channel diameter decreases, the frequency of rotation of the liquid increases in proportion to the ratio of the diameter of the swirl chamber and the outlet port, and accordingly the frequency of the wave radiation also increases.
  • a toroidal cavity connected to the interior of the vortex chamber is made in the wall of the vortex chamber on the section of the arrangement of its outlet channel.
  • the cavity of the swirl chamber is spherical.
  • the purpose of equipping the vortex chamber with the conical waveguide is to prevent hydrodynamic and hydroacoustic cavitation wear on the central part of the head of the vortex chamber.
  • the conical waveguide brings the cavitation bubbles outside the vortex chamber.
  • the taper taper ⁇ of the waveguide must not be above 20 ', i.e. 0 ⁇ ⁇ 20 '.
  • the assembly for generating hydrodynamic waves is provided with a resonance chamber, the cavity of which is connected to the cavity of the swirl chamber and in which a piston with a rod is accommodated with the possibility of displacement in the longitudinal direction.
  • the tuning to the resonance frequency takes place by moving the piston by means of a worm rod and by changing the volume of the resonance chamber under the piston.
  • the device for cleaning the zone near the borehole which is provided with the swirl chamber according to the invention, makes it possible to carry out a complex borehole treatment in connection with thermal-physical-chemical processes and to increase the productivity and the oil release of a layer.
  • the device has a simple construction, is reliable and suitable for production.
  • the device according to the invention for cleaning the zone near the borehole contains a hollow body 1 (FIGS. 1 to 4) with an inlet channel 2. Inside the body 1, a vortex chamber 3 of an assembly for generating hydrodynamic waves with tangentially directed inlet channels 4 is arranged.
  • the swirl chamber 3 has a conically tapering (funnel-shaped) outlet channel 5 for the outlet of a working medium.
  • the end face 6 of the chamber 3 is radially rounded, and a guide vane 8 is screwed to it by means of screws 7 such that an annular channel 9 is formed between them, which communicates with the annular space of the bore.
  • An annular mixing chamber 11 is formed in the borehole between the chamber 3 and a casing column 10, while an annular diffuser 12 is formed between the body 1 and the casing column 10.
  • the channel 10, the mixing chamber 11 and the diffuser 12 form a jet pump, which generates a vacuum in the work process and exerts a depression effect on a productive layer.
  • the device is centered in the borehole by ribs 13.
  • the device is connected to the casing column 14 by means of a conical thread.
  • a toroidal resonance chamber can be built into the wall of chamber 3 (FIGS. 6, 7) 21 with a combined annular inlet and outlet channel 22 (FIG. 6) and with a sharp edge 23.
  • the swirl chamber 3 (FIG. 10) is provided with a resonance chamber 25, in which a piston 26 with a rod 27 is accommodated.
  • the rod 27 is connected to the resonance chamber 25 by means of a screw connection.
  • the cavity of the swirl chamber 3 (FIG. 11) is spherical.
  • the device according to the invention for cleaning the zone near the borehole works as follows.
  • the working medium liquid, gas or multi-phase liquid
  • the pipes 14 (FIG. 1) into the inlet channel 2, from where it flows through the tangentially directed channels 4 into the swirl chamber 3.
  • the liquid begins to circulate at a high rotation frequency (within the range of 103 to 1.5.103 s ⁇ 1).
  • 5 hydroacoustic waves are generated in the outlet channel.
  • the turbulent pulsating flow from the outlet channel 5 is conveyed at a high speed in tangentially divergent directions, as indicated in FIGS. 1 and 12, and flows into the ring channel 9.
  • the liquid is directed upwards out of the annular channel 9 at a high speed and comes into an annular space - a mixing chamber 11 - and entrains the injected liquid from the zone near the borehole.
  • the velocities of the flows to be mixed are balanced, and the kinetic energy of the working flow is partly converted into the potential energy of the mixed flow.
  • the further conversion of the kinetic energy of the mixed flow into one Pressure energy occurs in the cavity of the diffuser 12.
  • the effect of a jet pump is realized in the annular space, and an additional depression is created in the zone of a productive layer.
  • the productive layer is exposed to both a depression and a wave effect. This creates mechanical activation processes in the zone near the borehole with signs of various nonlinear effects, the most important of which is the occurrence of hydrodynamic and hydroacoustic cavitation.
  • the turbulently pulsating current is conveyed from the outlet channel 5 of the swirl chamber 3 in tangentially divergent directions and runs onto the sharp edge 23.
  • the vibration of the leading edge 23 themselves is indicated by dashed lines.
  • the radial-tangential flow partly comes into the toroidal resonance chamber 21.
  • the bending vibrations of the leading edge 23 cause a pressure pulsation in the toroidal resonance chamber 21.
  • the ring channel 22 serves for the entry and exit of the liquid.
  • the current emerging from the toroidal resonance chamber 21 interrupts the incoming current with the oscillation frequency of the leading edge 23, which is why hydroacoustic waves are additionally generated at the edge 23.
  • the hydroacoustic waves and the cavitation effects in the zone near the borehole lead to the destruction of various deposits on the borehole wall and to the cleaning of the blocked pore channels in an oil layer.
  • the action of depression activates the development of cavitation, accelerates it the inflow of stratified petroleum to the borehole helps remove cleaning products from the pore channels.
  • the wave field has a significant impact on reducing the viscosity of bed fluid and petroleum, while the simultaneous depression effect increases their inflow to the borehole.
  • the device according to the invention can be used for cleaning the zone of a layer near the borehole in press-in bores in order to increase the absorption capacity of the layer. Without any design changes, it can be used as a shaft disperser, emulsifier, homogenizer of multi-phase liquids, for dispersing the drilling fluid and the cement slurry directly in the bore when carrying out the technological operations.
