Abstract
The utility model discloses one kind can free modular input/output port, including connector body and two connector of oil pipes of oil, two of them connector of oil pipes of oil linked together by screw thread and connector body both ends.The utility model can free modular input/output port when realizing coiled tubing docking, reduce polishing to tubing wall, avoid changing oil pipe intensity as far as possible, the best match docking of connector and oil pipe is realized, to reduce accident degree.
Description
Technical field
The utility model belongs to the energy field of operation such as petroleum, can the two-way company of free modular in particular to one kind
Device is connect, the docking of coiled tubing is mainly used for.
Background technique
Coiled tubing is the tubing made of low-carbon alloy steel, has very well as energy operation tubings such as mature oil fields
Flexibility, also known as coiled tubing, the long several kms of a roll of coiled tubing, outer diameter has 1 inch, 1.25 inches, 1.5 inches, 1.75 English
It is very little, 2 inches etc., wall thickness also has 0.125 inch, 0.134 inch, 0.145 inch, 0.175 inch, 0.204 inch etc. more than ten
Kind.Oil pipe a roll be equal wall thickness, but the oil pipe having is to mitigate weight, reduces intensity but still being able to satisfy operation needs
It wants, takes and become wall thickness manufacturing process, i.e., a roll of oil pipe is combined by several sections of the same outer diameter but different wall thickness.Continuous
In oil pipe operation technique, such as speed column technique, by coiled tubing G.I.H, after well head suspension, by oil pipe in well head
It cuts off, so whole disk oil pipe is divided into two parts.After technique use after a period of time, typically 3 to 5 years, need
By in well oil pipe recycling, thus need well head with input/output port by the oil pipe being divided into two pick up come.
Coiled tubing docking at present mainly takes following two mode to carry out operation: 1, weld: the operation mode is operation
Personnel are docked oil pipe by argon arc welding, and welding belongs to fire operation, and in well is inflammable and explosive oil gas, therefore be not suitable in well
Mouth uses.2, tool docks: using input/output port, two kinds of forms of mainly double dimples and double pressing roller type.Currently used doubly-linked
The outer diameter of the double dimples or double pressing roller type that connect device both ends is identical, but such as speed column oil pipe docks or falls well oil pipe and salvages
It docks, because the time is long or other a variety of causes cause the another part being originally divided into two to be not present or urgent operation
The input/output port brought mismatches oil pipe, and outer diameter is bigger than pipe aperture sometimes for tool, at this moment to expand pipe aperture i.e.
Wall thickness is thinned, this reduces the original intensity of oil pipe, and because of the thousands of rice bran oil pipes in underground, weight is at least more than ten tons, in addition frictional resistance
Possible tonnage is bigger, in addition when wall thickness is thinned because that wall thickness may be made to subtract is uneven for operative skill etc., in this way on oil pipe
During mentioning, may result in causes oil pipe to fall well in tool and the fracture of oil pipe junction.
In view of the above-mentioned problems, the utility model provide one kind can free modular input/output port, by the connector,
Can oil pipe connect when, at any time using and the most matched input/output port of pipe aperture, to be reduced as far as to oil pipe
The polishing of wall, and avoid changing oil pipe intensity.
Utility model content
The purpose of this utility model is to provide one kind can free modular input/output port, pass through the connector realize connect
Continuous oil pipe docks best match.
The purpose of this utility model is achieved by following technical solution:
One kind can free modular input/output port, including connector body and two connector of oil pipes of oil, two of them oil
Pipe connector is connected through a screw thread with connector body both ends.
Wherein, the connector body is hollow cylinder, and both ends internal diameter has internal screw thread, has thread groove on outer diameter,
Outer diameter size is consistent with oil pipe outer diameter.
Described connector of oil pipes of oil one end is dimple formula or pinch-roller type and has seal groove, and the other end is with externally threaded circle
Cylinder, it may be assumed that screw rod has seal groove above, places sealing ring in seal groove.
For being connected through a screw thread with oil pipe connector screw rod, external thread groove is the internal screw thread of the connector body
Increasing connector body curvature, when oil pipe is with lifting system and rollers running, oil pipe has a process by directly bent,
Corresponding oil pipe connector will also pass through this process, after having the thread groove of connector body, will increase the bending of connector
Degree.
The connector of oil pipes of oil is threadedly coupled by its screw rod with connector body, the sealing on screw rod in seal groove
Circle seals when connector body and connector of oil pipes of oil combine.
The connector form that the both ends of the connector body are connected can be freely combined, it may be assumed that can be connection dimple
Connector and/or double pressing roller type connector.Therefore, can be combined to can the double wine of free modular for the connected pipes and connector body
Nest connector, can free modular double pressing roller type connector and can free modular pinch roller-three kinds of dimple connector form.
The utility model provide one kind can free modular input/output port, realize coiled tubing docking when, reduce
Polishing to tubing wall avoids changing oil pipe intensity as far as possible, the best match docking of connector and oil pipe is realized, to reduce
Accident degree.
Detailed description of the invention:

Specific embodiment
With reference to the accompanying drawing, can be further described by embodiment for the double dimple connectors of free modular
The device of the utility model.
Present apparatus assembling and operation are as follows:
Can the double dimple connectors of free modular connector of oil pipes of oil seal groove in place corresponding sealing ring, then
The screw rod of connector of oil pipes of oil is screwed into connector body, until connector body is withstood at the dimple end of oil pipe connector.Equally
The connector body other end is also screwed into required connector of oil pipes of oil.Connector body and oil connection in this way is combined, dress
Being made into can the double dimple connector of free modular.
Then, by can the connector of oil pipes of oil of the double dimple connectors of free modular be inserted into an Oil-saving pipe, suppressed with dimple
Tool links together it with oil pipe, and equally the connector of oil pipes of oil of the other end is inserted into another Oil-saving pipe and is connected.
Lifting system can be started, operated upwards after the double dimple connectors of free modular link together two Oil-saving pipes,
Be lifted up with the oil pipe above movement connector, due to the oil pipe below oil pipe, connector and the connector above connector at
Be integrated, so above oil pipe band movement connector be lifted up, connector drives following oil pipe to be lifted up, finally will under
The oil pipe in face is enhanced out of oil well.
