Description
Technical field
The invention belongs to oilfield exploitation technical field, particularly relate to a kind of note and adopt one wellhead assembly.
Background technology
In oilfield exploitation, it is often necessary to use gas injection device and two kinds of equipment of extracting device of oil to complete corresponding operation.But find after a protracted use, such exploitation pattern also exists some drawbacks, first the production cost of two kinds of equipment is the highest, secondly after having noted gas, in addition it is also necessary to change corresponding extracting device of oil and recover the oil, the most not only production efficiency is low, operations number is the highest simultaneously, has carried out inconvenience to actual operation, is therefore badly in need of between a kind of gas injection device and extracting device of oil to carry out with mutual circulation the equipment of operation, and then improve work efficiency, simultaneously again can be time saving and energy saving.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: proposing a kind of simple in construction, production cost is low, the note that working performance is high adopts one wellhead assembly.
The technical solution of the present invention is achieved in that a kind of note adopts one wellhead assembly, including tubing head four-way, instlated tubular, the first gate valve, lower flange, four-way flange, oil pipe short circuit, box cupling, the second gate valve and hoop；It is provided with instlated tubular in described tubing head four-way；Two ends, described tubing head four-way left and right are provided with the first gate valve；Described tubing head four-way lower end is provided with lower flange；The first passage of mutual UNICOM, second channel and two third channels it are provided with in described four-way flange；Described tubing head four-way upper end is connected with the second channel in four-way flange；Said two third channel is connected to the first gate valve；Oil pipe short circuit it is provided with in described first passage；Described oil pipe short circuit is connected by box cupling and the second gate valve；Described second gate valve upper end connects hoop.
Preferably, it is additionally provided with back-up ring between described oil pipe short circuit and four-way flange.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The note of the present invention program adopts one wellhead assembly, its simple in construction, and easy to operate, production cost is low, and gas injection device and extracting device of oil can carry out operation with mutual circulation, improve production efficiency, decrease operations number, preferably meets the job requirements of reality.

Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
Of the present invention a kind of note as shown in accompanying drawing 1,2 adopts one wellhead assembly, including tubing head four-way 1, instlated tubular the 5, first gate valve 2, lower flange 3, four-way flange 4, oil pipe short circuit 6, box cupling the 7, second gate valve 8 and hoop 9；It is provided with instlated tubular 5 in described tubing head four-way 1；Described tubing head four-way about 1 two ends are provided with the first gate valve 2；Described tubing head four-way 1 lower end is provided with lower flange 3；The first passage 11 of mutual UNICOM, second channel 12 and two third channels 13 it are provided with in described four-way flange 4；Described tubing head four-way 1 upper end is connected with the second channel 12 in four-way flange 4；Said two third channel 13 is connected to the first gate valve 2；It is provided with oil pipe short circuit 6 in described first passage 11；Described oil pipe short circuit 6 is connected with the second gate valve 8 by box cupling 7；Described second gate valve 8 upper end connects hoop 9；It is additionally provided with back-up ring 10 between described oil pipe short circuit 6 and four-way flange 4.
Of the present invention a kind of note as shown in accompanying drawing 1-2 adopts one wellhead assembly, during real work, first gas injection work is carried out, after gas injection completes, carry out oil producing operation again, during oil recovery, first take out the instlated tubular 5 of tubing head four-way 1 internal layer, then the hoop of hoop 9 and oil production equipment is connected with each other, and finally utilizes oil pipe short circuit 6 can complete oil producing operation.
The present invention is greatly decreased flow chart, reduces operating cost, solves the flooding problems of this well simultaneously, effectively ensures to produce season.
During actual job, pressure during gas injection is 35MPa, and pressure is 21MPa when recovering the oil, because the pressure that the note of the present invention adopts one wellhead assembly use is 35MPa to the maximum, so when carrying out oil producing operation, the pressure needed due to oil producing operation is 21MPa, and the pressure of gas injection is 35MPa, meeting the most far away the needs of oil recovery, safety during operation has obtained sufficient guarantee.
The note of the present invention adopts one wellhead assembly, its simple in construction, and easy to operate, production cost is low, and gas injection device and extracting device of oil can carry out operation with mutual circulation, improve note and adopt efficiency, reduce operations number, preferably meet the job requirements of reality.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
