The technical scheme includes that the system mainly comprises a power source, a ground controller, a winch, a rotary drum, a lower sheave, a top sheave and an underground discharger, the ground controller connected with the power source is fixed into the winch, the rotary drum fixed into the winch is used for winding a cable, the cable penetrating through the lower sheave and the top sheave is connected with the underground discharger, and the underground discharger consists of a magnetic positioner, an electronic joint, an energy storage capacitor set and a discharging electrode which are connected with each other. The high-energy electrohydraulic explosion stratum treatment system has the advantages of higher power of high-energy electrohydraulic explosion compared with a common low-frequency electric pulse, capability of effectively eliminating blockage, large influence radius of a high-energy electrohydraulic explosion treatment oil layer, long period of validity, remarkable production increase and injection well stimulation effects, elimination of oil layer pollution and blockage, improvement of stratum permeability and further increase of crude oil production rate.
Description
One, technical field:
The utility model relates to a kind of oil-well strata treating apparatus, particularly a kind of high energy liquid discharge-induced explosion stratum treatment system.
Two, background technology:
Along with the continuous exploitation of oil, oilbearing stratum is polluted, and stops up, and in-place permeability descends, because the viscosity of crude oil is big, poor mobile performance makes the crude oil production difficulty and comes big more, the oil recovery worker technology that some are traditional makes the crude oil production decrease in efficiency, and output reduces.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of high energy liquid discharge-induced explosion stratum treatment system is provided, and carries out pulsed discharge by the position to oil reservoir, remove oil layer pollution, stop up, improve in-place permeability, and then improve crude output.
Its technical scheme is: mainly be made up of power supply, Ground Control instrument, winch, cylinder, lower sheave, top sheave and down-hole discharge instrument, the Ground Control instrument connects power supply and is fixed in the winch, resting barrel is used to twine cable in the winch, cable passes lower sheave, top sheave, connect the down-hole discharge instrument, described down-hole discharge instrument is connected to form by magnetic locator, electronics joint, energy capacitance set and sparking electrode.
The beneficial effects of the utility model are: the common low-frequency electric pulse of the power ratio of high energy liquid discharge-induced explosion is powerful, can effectively remove obstruction, the radius of influence that oil reservoir is handled in high energy electric detonation shake is big, period of validity is long, volume increase, the augmented injection effect is remarkable, removes oil layer pollution, stops up, improve in-place permeability, and then improve crude output.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: winch 1, Ground Control instrument 2, cylinder 3, lower sheave 4, top sheave 5, magnetic locator 6, electronics joint 7, energy capacitance set 8, sparking electrode 9, cable 10.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model mainly is made up of power supply, winch 1, Ground Control instrument 2, cylinder 3, lower sheave 4, top sheave 5 and down-hole discharge instrument, Ground Control instrument 2 connects power supply and is fixed in the winch 1, resting barrel 3 is used to twine cable 10 in the winch 1, cable 10 passes lower sheave 4, top sheave 5, connect down-hole discharge instrument, described down-hole discharge instrument is connected to form by magnetic locator 6, electronics joint 7, energy capacitance set 8 and sparking electrode 9.
During work, by winch the down-hole instrument that discharges is transferred to oil reservoir, the degree of depth determined by magnetic locator 6, Ground Control instrument 2 by cable to energy capacitance set 8 chargings of down-hole discharge instrument and control its discharge; By regulating Ground Control instrument 2, when energy capacitance set 8 charging voltages reach requirement, send the discharge control impuls to the down-hole, the electric energy that energy capacitance set is gathered instantaneous relase in well liquid makes well liquid vaporize rapidly, expand and set off an explosion, and the surge that blast is produced can reach 50～200MPa, and generation strong-electromagnetic field, the shock wave that the liquid discharge-induced explosion causes makes the stratum produce new microcrack, removes the deposition obstruction in the duct, stratum, reaches the purpose of plugging removal and stimulation augmented injection.
