Abstract
The utility model discloses a drilling sealing device is pressed in area, including a pipe body, the drilling rod, sealing nut and sealed rubber ring, the drilling rod is worn to establish in the body, the inside extension of pipe inner wall has the retaining ring, set up sealed rubber ring in the hou mian body of retaining ring, sealing nut overlapped the drilling rod and was in the same place with the body spiro union, the preforming has between sealing nut and the sealed rubber ring, sealing nut and preforming compress tightly with the drilling rod sealed rubber ring sealed, the front portion of drilling rod has the baffle, the effect of baffle is deviate from in preventing drilling rod follow retaining ring, the drill bit fixed orifices has been seted up at the anterior center of drilling rod, the lateral wall of drill bit fixed orifices has the screw, the locking screw spiro union is in the screw, the rear end of drilling rod has the drillstock, the lateral wall of body has the pressure release and connects, use the utility model discloses during punching operation, need not stop the back pressure release with equipment on the pipeline of normal operating, can not influence the normal operating rate of pipeline, can not produce the environment and pollute.
Description
Technical field
This utility model relates to the borehole sealing device with pressure used by a kind of oil field.
Background technology
On the pipeline that oil field is properly functioning during drilling operation, pressure release after often equipment must being stopped, having a strong impact on efficiency, and easily environment is produced and pollute.
Summary of the invention
The purpose of this utility model is to provide a kind of borehole sealing device with pressure.
This utility model includes body, drilling rod, sealing nut and O-ring seal, drilling rod is located in body, inboard wall of tube body has extended internally back-up ring, back-up ring body below arranges O-ring seal, sealing nut overlapped drilling rod and was screwed together with body, there is between sealing nut and O-ring seal tabletting, O-ring seal is compressed and seals with drilling rod by sealing nut and tabletting, the front portion of drilling rod has baffle plate, the effect of baffle plate is to prevent drilling rod from deviating from from back-up ring, the front central of drilling rod offers drill bit fixing hole, the sidewall of drill bit fixing hole has screw, lock screw is screwed onto in screw, the rear end of drilling rod has drillstock, the sidewall of body has relief fittings, relief fittings has the first external screw thread, the front portion of body has the second external screw thread.
Use process of the present utility model:
1, first running a bore position piece threaded high pressure line of welding of pipeline, and connecting high-pressure decompression valve, this high-pressure decompression valve is closed.Then, drill bit is arranged in the drill bit fixing hole of this utility model drilling rod, and locked by lock screw, body front portion is connected with high-pressure decompression valve, relief fittings is installed high pressure valve and closes.
2, then, open and be arranged on the high-pressure decompression valve run on pipeline, electricity consumption drilled through drillstock and drove drilling rod and bit, holed, after having holed on pipeline running, drill bit and drilling rod retreat to high-pressure decompression valve, then, close high-pressure decompression valve, then the high pressure valve in the relief fittings of body is opened pressure release, again body and this utility model are disassembled from the high pressure line run pipeline, so complete bore operation.
The beneficial effects of the utility model:
Use this utility model during drilling operation on properly functioning pipeline, it is not necessary to pressure release after being stopped by equipment, do not interfere with the properly functioning rate of pipeline, environment will not be produced and pollute.
Accompanying drawing explanation
Fig. 1 is sectional view schematic diagram of the present utility model.
Detailed description of the invention
nullRefer to shown in Fig. 1，The present embodiment includes body 1、Drilling rod 2、Sealing nut 3 and O-ring seal 4，Drilling rod 2 is located in body 1，Body 1 inwall has extended internally back-up ring 5，Back-up ring 5 body 1 below arranges O-ring seal 4，Sealing nut 3 overlapped drilling rod 2 and was screwed together with body 1，There is between sealing nut 3 and O-ring seal 4 tabletting 6，O-ring seal 4 is compressed and seals with drilling rod 2 by sealing nut 3 and tabletting 6，The front portion of drilling rod 2 has baffle plate 7，The effect of baffle plate 7 is to prevent drilling rod 2 from deviating from from back-up ring 5，The front central of drilling rod 2 offers drill bit fixing hole 8，The sidewall of drill bit fixing hole 8 has screw 9，Lock screw 10 is screwed onto in screw 9，The rear end of drilling rod 2 has drillstock 11，The sidewall of body 1 has relief fittings 12，Relief fittings 12 has the first external screw thread 13，The front portion of body 1 has the second external screw thread 14.
The use process of the present embodiment:
1, first running a bore position piece threaded high pressure line of welding of pipeline, and connecting high-pressure decompression valve, this high-pressure decompression valve is closed.Then, drill bit is arranged in the drill bit fixing hole 8 of this utility model drilling rod 2, and locked by lock screw 10, body 1 front portion is connected with high-pressure decompression valve, relief fittings 12 is installed high pressure valve and closes.
2, then, open and be arranged on the high-pressure decompression valve run on pipeline, electricity consumption drilled through drillstock 11 and drove drilling rod 2 and bit, holed, after having holed on pipeline running, drill bit and drilling rod 2 retreat to high-pressure decompression valve, then, close high-pressure decompression valve, then the high pressure valve in the relief fittings 12 of body 1 is opened pressure release, again body 1 and this utility model are disassembled from the high pressure line run pipeline, so complete bore operation.
