Tested VDT body of the present utility model is installed guide pad, and guide pad needs to be bundled on the VDT body with bandage; If the VDT body is unkitted guide pad, then the piston pressure testing arrangement should be installed.
The operating voltage 380V of motor in the utility model, electric current 220A; Water tank capacity is not less than 3m
3The nominal pressure of flashboard valve is not less than 20MPa, and pressure duct or high-pressure hose pressure-bearing are not less than 10Mpa.
In above-mentioned circulation line, the pressure bearing and seal circle is arranged between the pipeline crossover sub.
The integral installation of vertical drilling system also can be used as standby sealing valve before and after the purpose that installs flashboard valve on the high-pressure hose of the lower end of the VDT body of impulse generator top and vertical drilling system respectively additional is convenient test; The port of export of water tank and loop end install flashboard valve respectively additional, and purpose is a control water tank flowing water; The purpose that installs flashboard valve at the clarified water pump port of export additional is the control High-Pressure Water.
The operating principle of this testing arrangement, current are through manifold of ground, impact slurry generator, be the power supply of VDT system, system spreads out of pressure signal by impulse generator, by being converted to the signal of telecommunication after the pressure sensor perception, receiving by the ground decoder at last and by the software demonstration on computers, formed the on-the-spot of vertical drilling data and monitored in real time again.
When using of the present utility model the test,, open all valves, water can be entered in the whole test loop system,, be difficult to get to again the rated pressure value in order to avoid reduce rapidly because of the anhydrous pressure that makes in the circulating system when building the pressure at first with the water tank fills with water; Clockwise rotate the clarified water pump axle center for several times,, should open the venting of clarified water pump air valve, to the water column ejection is arranged if do not use for a long time; Inject butter at clarified water pump oil filler point place, to reach lubricated effect.When building the pressure for whole system, only close clarified water pump port of export flashboard valve, open main power source case power supply, remote console starts power supply, observes the clarified water pump pressure meter to more than the 3Mpa, slowly opens clarified water pump port of export flashboard valve, treats that pressure stability is about 3Mpa; There is the special messenger to be responsible for, will in time cuts off the electricity supply in case run into abnormal conditions at remote console; Observe system's real time data that computer shows, check whether various performance parameters is working properly; Every about ten minutes, about 90 ° of rotation VDT housing, whether various performance parameters is normal during with the measurement different azimuth.System testing finishes after about 1 hour, closes the Long-distance Control power supply, closes main power source simultaneously.
The utility model has reduced the economic loss that cisco unity malfunction caused behind the well on the instrument, saves the production time, has improved the production efficiency of service, lays the first stone for winning vertical drilling market.
