Abstract
A long-time-stop-well operation hole digger comprises a central rod, a pressing cap, a pressing cover, an oil seal, a sealing connector, a control valve, an observation valve, a hoop, a tee joint, a drill clamp and a drill. The long-time-stop-well operation hole digger is characterized in that the upper portion of the tee joint is connected with the control valve through the hoop, the upper portion of the control valve is connected with the sealing connector through threads, the central rod with the drill clamp and the drill penetrates through a central hole of the tee joint and a central hole of the control valve, the oil seal and the pressing cover are arranged between the sealing connector and the central rod, and the sealing connector is connected with the pressing cap in a threaded mode to press the pressing cover. The long-time-stop-well operation hole digger is suitable for drilling a well opening in long-time-stop-well operation of oil fields to carry out pressure release or well killing operation, and is convenient to operate, safe, reliable, and capable of effectively preventing oil well fires or blowout accidents.
Description
Technical field
the utility model relates to oil field Oil, Water, Gas well length and stops well operations well head perforate pressure release control device, specifically a kind of long well operations hole making drill that stops.
Background technology
at present, when the Oil, Water, Gas well in oil field stops production for some reason for a long time, in order to prevent head valve, accessory loss, conventionally adopt to remove and deposit, by the sealing of wellhead casing pipe flange welding, prevent contingency generation.In the time that the long Oil, Water, Gas well stopping needs again operation again, need to cut open with gas cutting, because OIH, atmospheric pressure are high, easily catch fire or gas blowout accident, cause very large economic loss to oil field.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of long well operations hole making drill that stops is provided.
technical solutions of the utility model comprise: center-pole, pressure cap, gland, oil sealing, seal nipple, by-pass valve control, observation valve, clip, threeway, drill jig, drill bit.It is to connect with by-pass valve control by clip on threeway top that described length is stopped well operations hole making drill, the top of by-pass valve control is threaded with seal nipple, the center-pole that drill jig, drill bit are housed passes from the centre bore of threeway, by-pass valve control, oil sealing, gland are housed between seal nipple and center-pole, seal nipple is threaded with pressure cap, and gland is compressed.
the seal nipple top that above-mentioned length is stopped in well operations hole making drill is provided with observation valve.
the central post top portion that above-mentioned length is stopped in well operations hole making drill is provided with square head, is convenient to be connected with power.Power is selected hydraulic pump, motor or air driven pump.
the beneficial effects of the utility model are: are applicable to oil field length and stop well operations and bore the mouth that drives a well, bleed off pressure or implement kill job, and easy to operate, safe and reliable, effectively avoid oil well to catch fire or gas blowout accident occurs.

Detailed description of the invention
below in conjunction with accompanying drawing, the utility model is described in further detail:
shown in accompanying drawing, oil field length is stopped well operations hole making drill by center-pole 1, pressure cap 2, gland 3, oil sealing 4, seal nipple 5, by-pass valve control 6, observation valve 7, clip 8, threeway 9, drill jig 10, drill bit 11.It is to connect with by-pass valve control 6 by clip 8 on threeway 9 tops that described length is stopped well operations hole making drill, the top of by-pass valve control 6 is threaded with seal nipple 5, seal nipple 5 tops are provided with observes valve 7, the center-pole 1 that drill jig 10, drill bit 11 are housed passes from the centre bore of threeway 9, by-pass valve control 6, oil sealing 4, gland 3 are housed between seal nipple 5 and center-pole 1, seal nipple 5 is threaded with pressure cap 2, and gland 3 is compressed.
install and operation
first, use bolt connected pipes overhead method orchid at wellhead casing pipe flange.Secondly, tighten drill bit 11, the suitable for reading of the end opening of threeway 9 and tubing head upper flange is connected with clip 8, the side exit of threeway 9 is connected with open flow gate, blooie pipe.The 3rd, observing valve 7 setting pressure tables, center-pole 1 top square head 101 is connected with hydraulic pump, connect hydraulic power source, drive center-pole 1 to rotate, center-pole 1 drives drill bit 11 well head can be bored and opens, and opens open flow gate, blooie pipe pressure release, be zero until observe valve 7 Pressure gauge pressure drops, can carry out subsequent job construction to oil well.
