Abstract
The present invention relates to a kind of oil drilling circular screen.It is characterized in that including transmission band, screen cloth；The side of screen cloth is connected with transmission band, and the side of screen cloth is imbedded in the middle of conveyer belt or surface combination on a moving belt, is integrally forming；Being provided with coupling part on screen cloth, the two ends of screen cloth are coupled together by this coupling part, become closed hoop.Beneficial effects of the present invention: 1, screen cloth is driven by certain driving means, shuttling movement, the subrange of the mud so got off constant impingement originally expands, and decreases the concentrated wear of conventional monolithic screen cloth, extends screen cloth service life；2, the oil drilling circular screen of the present invention only need to increase in mud fall area and supports, and decrease the cost of manufacture of individual screen cloth, simultaneously because improve screen cloth service life, individual screen cloth one layer can realize the purpose separated, and has saved cost of manufacture.
Description
Technical field
The present invention relates to a kind of oil drilling circular screen.
Background technology
In petroleum drilling engineering, screen cloth is mainly used in vibrosieve equipment at present, uses the screen cloth of different big small-bores
Carry out removing and the collection work of useful solid phase of useless solid phase in drilling fluid.Drilling technology serve more and more heavier
The effect wanted, becomes an indispensable part in well system, is to improve drilling efficiency, the important auxiliary of reduction drilling cost
One of instrument.Current screen cloth is to cooperate with using the most entirely, and this just requires that screen cloth entirety needs to be tensioned to certain requirement, so as to
Meet the requirement of vibrating inertia force, reach optimum separation efficiency, simultaneously because one of the lasting impact screen cloth of drilling fluid solid
Determining region, cause screening media serious, change frequently, for solving this problem, net successively have employed Double-layer screen, multi-deck screen
Net, the mode such as screen cloth and multiple screen design combination of binding increase the service life of screen cloth, simultaneously the most gropingly various
Which kind of mode is moderate scheme in terms of separation efficiency and service life and maintenance under operating mode in combination, no matter but using all also exist
The shortcoming of similar following several respects: (1) is short for service life；(2) mesh structure is unreasonable, poor filtration effect；(3) screen cloth
Change inconvenience etc..
Screen cloth is as the equipment consumable goods of oil drilling industry at present, always reduces drilling cost, improves equipment and uses
How the important restriction factor in life-span, design a kind of brand-new mesh form for oil drilling industry, to solve drilling cost
Too high, the plant maintenance cycle is frequent, the separating effect difficult problem such as persistently, and reach to change convenient, the requirement such as length in service life, reply
Nowadays under Energy Competition environment, obtain maximum value with minimum input, be oil drilling industry urgent problem.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide a kind of oil drilling circular screen
Technical scheme.
Described a kind of oil drilling circular screen, it is characterised in that include transmission band, screen cloth；The side of screen cloth and biography
Dynamic band connects, and the side of screen cloth is imbedded in the middle of conveyer belt or surface combination on a moving belt, is integrally forming；The company of being provided with on screen cloth
Connecing part, the two ends of screen cloth are coupled together by this coupling part, become closed hoop.
Described oil drilling circular screen, it is characterised in that described coupling part use knit, sew up, vulcanize,
Bonding, riveting or be arranged on screen cloth by the mode of third party's fastener.
Described oil drilling circular screen, it is characterised in that described screen cloth uses wire netting, nonmetal net, filter cloth
Or filter paper.
Described oil drilling circular screen, it is characterised in that be connected by between described transmission band and screen cloth compiling
Tie, sew up, vulcanize, the mode of bonding, riveting or third party's fastener connects.
Beneficial effects of the present invention:
1, screen cloth is driven by certain driving means (roller, carrying roller, belt or similar anaclisis device), circulating
Dynamic, the subrange of the mud constant impingement originally so got off expands, and decreases the concentrated wear of conventional monolithic screen cloth, extends
Screen cloth service life；
2, the oil drilling circular screen of the present invention only need to increase support in mud fall area, decreases the system of individual screen cloth
Making cost, simultaneously because improve screen cloth service life, individual screen cloth one layer can realize the purpose separated, and has saved and has been fabricated to
This；
3, oil drilling circular screen as the term suggests be annular circumferentially screen cloth, its combination can use snapping, bonding,
Overlap joint, easy pulling buckle etc. multiple link form, convenient and swift, the most whole screen cloth can be rolled up together or stacking when depositing
Placing, individual parking space is flexible, it is simple to store transport etc..
Accompanying drawing explanation
Fig. 1 is the structural representation of the oil drilling circular screen of the present invention；
Fig. 2 is A-A cut-away illustration in Fig. 1；
Fig. 3 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
As it is shown in figure 1, a kind of oil drilling circular screen, it is made up of transmission band 1, screen cloth 2 and coupling part 3；The side of screen cloth 2
Limit uses bonding way to be connected with transmission band 1, is integrally forming；Such as Fig. 2, shown in 3, the side embedment conveyer belt of screen cloth 2
The centre of 1；Coupling part 3 uses the mode sewed up to arrange on the screen 2, by this coupling part by the two ends of screen cloth
Couple together, form the oil drilling circular screen of closed hoop.
Flat rubber belting selected by the oil drilling of the present embodiment circular screen conveyer belt, and screen cloth uses wire netting.
The oil drilling circular screen of the present invention can also use global formation pattern, is prefabricated into the oil of closed hoop
Drilling well circular screen.
The operation principle of the oil drilling circular screen of the present invention is: oil drilling circular screen passes around rear and front end
Action roller forms closed-loop path, forms a flat screen cloth face under the tensioning of both sides belt wheel, and filter medium passes screen cloth face, than sieve
The solid phase particles that mesh is big is stayed on screen cloth, and gas or liquid and little granule solid thing, through screen cloth, reach to separate purpose.Along with
The rotation of live-roller, screen cloth does shuttling movement, arrives screen cloth at roller and returns back to roller lower end, and bulky grain solid phase is divided with screen cloth
From, fall at solid phase collection.
