Abstract
The utility model relates to an electric detonation plugging removal apparatus for a technology used by petroleum injection production. The utility model has the advantages of high effect of plugging removal, low price, simple manufacturing process and low construction cost. The utility model is composed of a sealing cable end, a step-up transformer, a rectifier filter, an energy storage capacitor, a discharge switch and electrodes. A 30KV direct current is produced via boosting, rectifying and filtering, the energy storage capacitor is charged up; under the control of the discharge switch, explosion is formed by electrode discharge, strong cutting force can be produced among each of layers, and thus, the staggered action of the layers occurs. The utility model has the advantages that a seepage passage is improved, stemmings in an oil seepage pore canal is effectively stripped, and the utility model plays a role in the plugging removal. The purpose that oil well yield is improved is achieved.
Description
The utility model relates to the petroleum recovering yield-increasing apparatus, the electric detonation shake unblocking instrument that especially a kind of de-plugging of well is used.
The oil well in oil field and water injection well are in drilling well, completion and manufacturing process, can be polluted unavoidably, conventional method for removing blockage has measures such as fracturing, acidifying, high enegry gas fracturing, its major defect is apparatus expensive, construction technology more complicated, the operating expenses height has the possible of repeated contamination to oil reservoir.
The purpose of this utility model provides a kind of electric detonation shake plug-removing device, can effectively remove oil-well strata and stop up, and equipment is cheap, operating expenses is low and can not cause secondary pollution to the stratum.
The technical solution of the utility model is achieved in that
Electric detonation shake plug-removing device comprises cable head, step-up transformer, rectifier filter, energy-storage capacitor, discharge switch and electrode composition.
During work, ground power supply A delivers to cable head 1 with the alternating current of 220V/50Hz by the cable of going into the well, boost by step-up transformer and rectifier filter 2, rectification, in the filtering input energy-storage capacitor 3, under the control of discharge switch 4, by electrode 5 medium transient state puncture in down-hole is entered plasmoid, energy discharges rapidly and forms blast, generating peak pressure reaches under the impact stress ripple effect of 200～300MPa, to produce powerful shearing force between each aspect and frustrate, generate new sepage duct, also will extend under the effect of impact stress ripple in former seepage flow duct, improve oil well output.
The beneficial effects of the utility model are the de-pluggings that a kind of low price, construction technology is simple, operating expenses is low device are used for the stratum, it can peel off obstruction and pollutant in the stratum effectively, and can not produce repeated contamination, overcome the shortcoming of pressure break, acidifying the stratum.
