An apparatus for processing bottom zone of productive strata

摘要

The invention relates to the mining industry, namely to the field of production of flowable liquid or gaseous media through the boreholes and can be used to increase the permeability of the collectors in the processing bottomhole zones productive formations, in particular, composed of dense tight clastic rocks, impermeability which is caused by relaxation of the stresses around the borehole.; The basis of the utility model the task to develop an apparatus for processing bottomhole formation zone which would allow through improved diverter achieve the possibility to concentrate the acoustic effect in the slits perforations, directing it to the equilibrium zone are equilibrated confining pressure, turbulize flow of hydraulic fluid in place of the diverter location creating cavitation, and then create an additional force action, which extends the It complements and reinforces the effect achieved by the influence of cavitation and sound pulse, and thereby reduce the working pressure generated by the device, which is necessary for cracking and to increase its reliability and workability.; To this end in a device which comprises Colon sealed nasosnokompressornyh pipe over which is arranged to transmit the action deeper into the column generator hammer and at the lower end is set the deflection device, the reservoir with the working fluid, the pump having an input connected to the tank, and the output from the void column , means for sealing the borehole, means for sealing the top of the columns, the deflection device is designed as a hollow body of revolution, inside which cavity in its lower part is mounted to nical reflector on the side surface of which there are longitudinal, through slots, the length of which equals the value of the projection on the vertical axis of the borehole minimum distance between two adjacent slits perforations. When this rotation body can be formed as a hollow cylinder or a hollow hyperbolic paraboloid, cone reflector is arranged to adjust the gap mezhd.u inner lateral surface of revolution and the cone of the reflector body, and an inner side surface of through longitudinal grooves situated at an acute angle to the side surface of the body rotation so that the groove opening on the outer surface of the rotation body was smaller than the groove opening on its inner surface.; 1 n.p.f Lee, 5 ZP whether f-1 yl.; ESSAY
