Abstract
The utility model is related to oil collecting equipment field, specifically a kind of split type double tube christmas tree；It is characterized in that：Including adapter, fan-shaped flange, long oil pipe, short oil pipe, WKM expansion valves, three-way component and pipe plug；The adapter, fan-shaped flange and three-way component include two tubing interfaces, and long oil pipe, short oil pipe and pipe plug have two pairs；Wherein, two flow strings are formed after being connected between two pairs of long oil pipes and two pairs of short oil pipes by WKM expansion valves, the bottom and top of flow string are connected by fan-shaped flange with adapter and three-way component respectively, and pipe plug is additionally provided with three-way component.This production tree can also can independently be exploited simultaneously by different oil reservoirs in the same oil well of double tube drilling, two oil reservoirs.Thus, once wherein one oil pipe needs to stop work, the operation of an oil pipe in addition does not receive influence, so facilitates the production and maintenance of oil producing operation.
Description
Technical field
The utility model is related to oil collecting equipment field, specifically a kind of split type double tube christmas tree.
Background technology
Single tube production tree operationally can only fix some oil reservoir in the same oil well of drilling, when the valve of production tree needs dimension
When repairing or changing, whole production tree must wholly off operation, mode of operation so production cost and to safeguard into difficulty
Effectively to be reduced.
The content of the invention
The purpose of this utility model is to have split type two-tube production tree there is provided a kind of.
In order to achieve the above object, the utility model is realized in：
A kind of split type double tube christmas tree, including adapter, fan-shaped flange, long oil pipe, short oil pipe, WKM expansion valves, threeway
Component and pipe plug；The adapter, fan-shaped flange and three-way component include two tubing interfaces, long oil pipe, short oil pipe and pipe
It is stifled to have two pairs；Wherein, two flow strings are formed after being connected between two pairs of long oil pipes and two pairs of short oil pipes by WKM expansion valves,
The bottom and top of flow string are connected by fan-shaped flange with adapter and three-way component respectively, and pipe is additionally provided with three-way component
It is stifled.
Described split type double tube christmas tree, two flow strings are inverted relatives, are specifically：The long oil of a piece flow string
Pipe is located at bottom, and short oil pipe is located at top, and the short oil pipe of another flow string is located at bottom, and long oil pipe is located at top；Thus, making
Obtain the interlaced setting of two WKM expansion valves on two flow strings.
This production tree can also can independently be opened simultaneously by different oil reservoirs in the same oil well of double tube drilling, two oil reservoirs
Adopt.Thus, once wherein one oil pipe needs to stop work, the operation of an oil pipe in addition does not receive influence, so convenient to recover the oil
The production and maintenance of operation.
Brief description of the drawings
Fig. 1 is the structural representation of the present apparatus.
Embodiment
The utility model is further illustrated below by way of specific embodiment.
As shown in figure 1, a kind of split type double tube christmas tree, including adapter 1, fan-shaped flange 2, long oil pipe 3, short oil pipe 4,
WKM expansion valves 5, three-way component 6 and pipe plug 7；The adapter 1, fan-shaped flange 2 and three-way component 6 connect including two oil pipes
Mouthful, long oil pipe 3, short oil pipe 4 and pipe plug 7 have two pairs；Wherein, it is swollen by WKM between two pairs long oil pipe 3 and two pairs of short oil pipes 4
Swollen valve 5 forms two flow strings after connecting, the bottom and top of flow string respectively by fan-shaped flange 2 with adapter 1 and three
Logical component 6 is connected, and pipe plug 7 is additionally provided with three-way component 6.
Described split type double tube christmas tree, two flow strings are inverted relatives, are specifically：The long oil of a piece flow string
Pipe 3 is located at bottom, and short oil pipe 4 is located at top, and the short oil pipe 4 of another flow string is located at bottom, and long oil pipe 3 is located at top；Such as
This so that the interlaced setting of two WKM expansion valves 5 on two flow strings.
In this split type double tube christmas tree, adapter 1 is standard clamp connection, and there is RX gasket rings groove at two at top, passes through RX
Gasket ring realizes the sealing with fan-shaped flange 2.
Fan-shaped flange 2 is API standard flanges, and the connection with adapter 1 and three-way component 6 is realized by bolt.
The long two ends of oil pipe 3 are all UP TBG screw threads, and one end is spun on valve body, and one end is spun on fan-shaped flange 2, and screw thread connects
The place of connecing is welded according to standard, and weld seam carries out ray or ultrasonic examination.
WKM expansion valves 5 are a kind of manual expansion sluice valves, and the end of thread realizes pit shaft flow channel switch by switching flashboard.
Short oil pipe 4 is with as long oil pipe 3, and two ends are all screw threads, and one end is spun on valve body, and one end is spun on fan-shaped flange,
Threaded connection place is welded according to standard, and weld seam carries out ray or ultrasonic examination.
This production tree can also can independently be opened simultaneously by different oil reservoirs in the same oil well of double tube drilling, two oil reservoirs
Adopt.Thus, once wherein one oil pipe needs to stop work, the operation of an oil pipe in addition does not receive influence, so convenient to recover the oil
The production and maintenance of operation.
