Description
Technical field
The utility model is related to the auxiliary tools in petroleum machinery, drilling-production equipment operation process.
Background technology
Casing head is the basic components of petroleum machinery, wellhead equipment, carries fixed well location, the well-digging of guiding drilling machine, suspension
The effect of miscellaneous equipment on underground multilayer sleeve and connection well.It is anti-since drilling well is a complexity and longer operation process
The only big part of steels such as drill bit, drilling rod and casing of disengaging casing head damages or wears its accurate lumen orifice, influences its rear sleeve
The installation of hanger；Therefore, in the lumen orifice of casing head, abrasionproof bushing can be installed and used.But not due to the type of oil gas
It is different with, well depth, hole condition is different, pressure is different, cause the outer diameter of the specifications and models of casing head, level quantity, each layer casing to be
Outer diameter to abrasionproof bushing also differs；If using twin-stage or Multi-stage sleeve head, can respectively pacify on same well head
Dress uses the abrasionproof bushing of more than two various outer diameters.
Casing head abrasionproof bushing used at present and taking-up tool, are all corresponding configuration one by one, i.e., a kind of outer diameter
Abrasionproof bushing must a kind of mating taking-up tool.The outer diameter of common casing head latus rectum and abrasionproof bushing has 7~8 kinds, institute
Also there are 7~8 kinds with mating taking-up tool, it is mutually not general；In addition the casing head abrasionproof bushing design shape of each manufacturing enterprise and
Size is different, so, it is just less general；The abrasionproof bushing of situ of drilling well can often be caused and take out tool bulk deposition, added
The volume of upper abrasionproof bushing and taking-up tool is larger, steel is heavy, makes its keeping and using cumbersome.Then be formed by
Abrasionproof bushing after use and taking-up tool of good performance, together as the custom of scrap iron processing；Installing and using new set
When tube head, then each manufacturing enterprise is allowed to provide a full set of abrasionproof bushing again and taking-up tool causes great people year after year
The waste of power, material resources.In addition, the taking-up tool of various various outer diameters, generally there is a pipe fitting of identical connection drilling rod, but because
To take the outer diameter of set main body different, so duplication of production of having to, this is also that metal material is caused to waste and increase business burden
One of factor.
Invention content
The utility model lies in that in view of the above-mentioned problems, using standardized technique, existing product structure is combined and is set
Meter, to realize a set of taking-up tool, takes out the abrasionproof bushing of a variety of various outer diameters, and makes it have and facilitate preservation and repeat to make
With the advantages of, with achieve the purpose that save social resources, reduce production and cost for oil production.
The taking-up tool of the utility model, using pipe fitting part and the composite structure for taking set component to be combined, characteristic
Place is：What one pipe fitting part arranged in pairs or groups multiple and different outer diameters takes set component, and set component is taken to take set main body by various outer diameter
Couple respectively with snap pin, holding screw；Pipe fitting by the spiro column of lower end respectively with each center for taking set main body
Threaded hole is connected, and using a closed groove mounted in the root diameter taken in set main body on holding screw and pipe fitting
It is fixed；In the circumferential edge for taking set main body, it is evenly distributed with 3~4 snap pins with thread connection.
Due to the utility model using a pipe fitting part arrange in pairs or groups it is multiple take set component composite structures, reached with one
Tool is extracted out, the purpose of various outer diameter abrasionproof bushing in casing head used can be taken out；Reduce in the past in taking-up in heaps
It checks the number in tool the trouble of searching, also avoids the situation that taking-up tool is integrally discarded.The composite structure also avoids more
The duplication of production of identical pipe fitting significantly reduces the weight of product, has saved manpower, material and energy because duplication of production wastes
Source.Uniform sizes take set part centre threaded hole, be more advantageous to a plug connect it is multiple take set component, with facilitate
Packaging, keeping, transport and the use of taking-up tool.Pipe fitting and set component is taken to be fixed using thread connection, holding screw, had
Couple it is reliable, convenient for disassembly and assembly, avoid part scatter and disappear.Respectively take set component in, using consistent appearance size, specifications and models and
The snap pin and holding screw of thread connection, make it have extensive interchangeability, easy to produce, use and repair.This practicality is new
Type is also beneficial to drilling crew and forms the long-term keeping to taking out tool and reuse while reducing cost, economizing on resources
Good habit.
