Abstract
The utility model belongs to equipment manufacturing field, specifically a kind of multichannel oil pipe and its complementary connector, it is characterized in that: including multi-way joint male end, multi-way joint female end, multichannel oil pipe ontology, multichannel oil pipe support plate and seal disc constitute multichannel oil pipe and its connector interfaces system of complete set.Two multichannel oil pipes when rear connection, do not have to rotation pipeline ontology in channel pair, only with the connecting cylinder for rotating female end, that is, can reach the effect of two oil pipes of connection.Upon connection, the seal disc between male end and female end achievees the effect that sealing automatically by sealing cone to two multichannel oil pipes, gangs up each channel mutually not, realizes the fluid in each channel in the effect of different stratum target zone operations.Moreover, the joints size of multichannel oil pipe is consistent with conventional oil pipe, the rig tool of conventional oil pipe be can also be used on multichannel oil pipe.
Description
Technical field
The invention belongs to equipment manufacturing field, specifically a kind of multichannel oil pipe and its complementary connector.
Background technique
Oil pipe is that channel between target zone (oil reservoir or water layer) and ground installation is established in petroleum drilling and mining industry petroleum production engineering
Important pipe string portion, be indispensable in oil pumping, water filling and the flow charts such as acid fracturing.Current is to realize drilling well
The maximization of benefit, often a well will bore open multiple target zones, and the technology for separating and blocking is taken to be divided in later development
Layer exploitation that is, in a period of time, only develops a target zone.Standardization oil pipe common at present, tube body itself are all single logical
Road, i.e. a pipe, both ends are connectors, and connector is divided into monoblock type and non-integral type (i.e. with box cupling).With this oil pipe
Single channel between the stratum and earth's surface of foundation, can only one target zone of primary development, be unable to Multi-layer synchronous exploitation, developing
When other purposes layer, it is also desirable to lower oil tube again opens target zone, and lower oil tube will introduce workover rig and carry out operation,
It takes time and effort, causes the increase of oil field operation cost.
Innovation and creation content
Applicant is in the work of long campaigns machine design and manufacture, by constantly exploring and studying, it is therefore intended that mention
For a kind of multichannel oil pipe and its complementary connector, improves current oil field and replace work in the oil well or well with multiple target zones
During industry target zone, the drawbacks of workover rig carries out lower oil tube operation, operating cost is caused to increase is used for multiple times, reaches reduction
The purpose of lower oil tube operations number, while solving the problems, such as that single oil pipe channel cannot be in multiple target zone synchronous developments.
The present invention adopts the technical scheme that by its technical problem of solution, provides a kind of multichannel oil pipe and its with socket
Single channel oil pipe common at present is become multichannel oil pipe, and in the feelings for not changing current oil pipe operation technique largely by head
Under condition, a kind of connector to match with multichannel oil pipe is designed, to realize multiple purposes on the basis of existing operation technique
Lower oil tube operations number is reduced when layer synchronous development or asynchronous exploitation, composition includes: multichannel tube body, multichannel oil
Pipe fitting male end, multichannel oil connection female end, support plate, seal disc etc..
Further, the multichannel tube body is made of, between oil pipe at a certain distance multiple standardized thin oil pipes
It is arranged evenly, convenient for each channel is separated in joint.
Further, the multichannel oil connection male end, is provided with multiple ducts, consistent with the quantity in oil pipe channel, public
There is external screw thread on the outside of connector, pin end top and oil pipe ontology are welded to connect, and pin end lower part is reserved with close with seal disc cooperation
The conical surface of envelope.
Further, the multichannel oil connection female end is divided into female end ontology and connecting cylinder, the female end body upper part
It is reserved with the conical surface with seal disc cooperation sealing, lower part and oil pipe ontology are welded to connect, multiple ducts are provided on female end ontology, with
The quantity in oil pipe channel is consistent, the connecting cylinder, and shape is a cylinder, and inner lower is machined with locking step, and upper inside has
Internal screw thread.
Further, support plate is a porous disc, and duct quantity is consistent with oil pipe body quantity.
Further, seal disc is a porous disc, and duct quantity is consistent with oil pipe body quantity, and each duct is boss knot
Structure, boss is up and down with sealing cone.
Beneficial effects of the present invention are analyzed as follows:
(1) each member function: the multichannel tube body can set up multiple channels that do not gang up mutually, the multichannel oil
Pipe fitting male end and the multichannel oil connection female end are located at the both ends of tube body, play fixed tube body and connect other tube bodies
Effect, the support plate is located in the middle part of tube body, can have many places, play segmentation support tube body, prevent tube body flexibility excessive and become
The effect of shape, the seal disc are located between the male and female end of multichannel oil connection, play the role of sealing the joint.
(2) advantage illustrates: 1. an oil pipe operation can be directed at multiple target zones, it is possible to reduce make a trip number, significant to drop
Low operating cost.2. its outer dimension, especially joint dimension are consistent with common conventional oil pipe, the well head for conventional oil pipe
Tool such as tubing tongs, elevator, slips can also be used on multichannel oil pipe, without the operation work for excessively changing current oil pipe
Skill.
In conclusion a kind of multichannel oil pipe of the invention and its complementary connector, compared with prior art, function is obtained
Extension has been arrived, traditional oil pipe operation technique once lower brill has been solved, a target zone can only be directed at and multiple purposes cannot be directed at
The problem of layer operation, has reformed the application method of oil pipe, has improved operation technique, to achieve the effect that reduce operating cost.
