Abstract
The utility model discloses an electromagnet blowout prevention box, and relates to the technical field of drilling tool mud blowout preventers for petroleum drilling. The electromagnet blowout prevention box comprises a box body, wherein an electromagnet is installed on the box body, and the electromagnet is connected with an electromagnet switch installed on the box body. The electromagnet blowout prevention box solves the problems that a mud blowout prevention box is impacted by high-pressure mud, and is toppled over, meanwhile solves the problem that mud leakage is overlong in time, and the technical problems that jamming and adherency of a drilling tool are easy to appear, also solves the problem of pollution of mud, and saves production cost.
Description
Technical field
The utility model relates to the drilling equipment technical field, relates in particular to oil drilling drilling tool slurry preventer technical field.
Background technology
In existing blowout prevention box use procedure, high-pressure slurry fluid impact blowout prevention box, general driller adopts artificial righting, with it the fluid that mud is revealed might be sprayed on, perhaps pours in the eye, causes the generation of unsafe factor.When revealing mud, adopt slowly and reveal, cause drilling tool long quiescent time, be prone to the adhesion bit freezing.The most of Fang Jingzhong that flows into of the mud of revealing can't reuse, and has caused mud waste and environmental pollution.
Publication number is CN202064877U, and the Chinese patent literature that open day is on December 7th, 2011 discloses a kind of sealed blowout preventing box, is used for preventing that drilling fluid from leaking when oil drilling makes a trip.The utility model is made of box body, connection bearing pin, strengthening steel slab, sealing snap close, caulking gum, screw and draining valve, box body integral body is cylindric, the end face of box body and bottom center have the drilling tool trepanning, it is inboard by screw caulking gum to be fixedly mounted on the drilling tool trepanning, connect the box body that bearing pin connects two semicircle tubulars, strengthening steel slab is equipped with in the side of box body, and draining valve is equipped with in the bottom of box body side.During use, this sealed blowout preventing box is sleeved on the drill pipe coupling, will seals bolt and the dense block padlock is tight, connect with flexible pipe in the draining valve the opened umbrella under the rig floor.The utility model has been stopped the drilling fluid waste, has avoided the infringement to operating personnel and equipment, safety and environmental protection.
But the prior art take above-mentioned patent documentation as representative, although blowout prevention box is tightly connected with drilling tool, but in use, but it is not firm to connect, before being tightly connected, still need artificial righting, in use, with it the fluid that mud is revealed might be sprayed on, perhaps pour in the eye, cause the generation of unsafe factor.The most of Fang Jingzhong that flows into of the mud of revealing can't reuse, and has caused mud waste and environmental pollution.
Summary of the invention
For solving existing technical problem in the above-mentioned prior art, the utility model proposes a kind of electromagnet blowout prevention box, the utility model has solved spray arrester and has been subject to the problem that the high-pressure slurry impact is toppled over, solved simultaneously the long problem of mud leak time, be prone to the technical problem that adheres to bit freezing, also solve the pollution problem of mud, saved cost of production.
The utility model is by adopting following technical proposals to realize:
A kind of electromagnet blowout prevention box comprises box body, it is characterized in that: at box body electromagnet is installed, electromagnet is connected with electro-magnet switch on being installed in box body.
Be provided with at least two group wire rope amortisseur bars in the described box body, wherein the length of one group of wire rope amortisseur bar is greater than the length of another group wire rope amortisseur bar, and an end of wire rope amortisseur bar is connected with the box body inner top, and the other end is free end.
Be provided with the dashboard that is in tilted layout in the described box body, dashboard is connected with the inwall of box body.
Be communicated with the mud veclamation pipe at described box body.
Described electromagnet is 3, and 3 blocks of electromagnet form a circle, and 3 blocks of electromagnet evenly distribute on box body.
Compared with prior art, the beneficial effects of the utility model show:
1, in the utility model, adopts and at box body electromagnet is installed, the work of electromagnetic switch control electromagnet, thereby with box body electricity consumption magnet adsorption, thereby stopped manpower righting blowout prevention box, reduced the injury to human body, solved spray arrester and be subject to the problem that the high-pressure slurry impact is toppled over.
2, in the utility model, be provided with at least two group wire rope amortisseur bars in the box body, reduced the impact force of high-pressure slurry to the blowout prevention box wall, solved the long problem of mud leak time, be prone to the technical problem that adheres to bit freezing, saved the single time of dismounting, reduce engineering accident or complexity.
3, in the utility model, be provided with the dashboard that is in tilted layout in the box body, be used for reclaim mud, reduce or stop mud and trickle down at rig floor, reduce mud to the pollution of environment, save simultaneously mud, reduced to produce rising this.
4, in the utility model, be communicated with the mud veclamation pipe on the box body, so just can reclaim mud, reduced environmental issue, saved the mud expense.
