Embodiment
Embodiment 1：
In order to overcome line size in existing associated gas recovery device to fix, installation trouble, time-consuming and laborious, of high cost asks
Topic, present embodiments provides a kind of associated gas recovery device as shown in Figure 3 and Figure 4, including well logging valve 1, pipeline 1, pipeline
23 and constant pressure valve 4, the pipeline 1 and pipeline 23 be retractable structure, the connection between the pipeline 23 and constant pressure valve 4
There is certain inclination angle with horizontal axis direction in the horizontal plane, connect between the pipeline 1 and pipeline 23 by a pipeline
Head connection, pipeline 1 is vertical direction, and pipeline 23 is horizontal direction.
Pass through the height and length of pipeline 1 and the telescopic adjustment pipeline of pipeline 23 in the present embodiment so that pipeline meets
The well head size of crude oil well, in this way, for the well head of various sizes of crude oil well, without first measuring the reprocessing installation of well head size
Pipeline, avoids process piping and causes a deviation the trouble re-worked, improve work efficiency.
Meanwhile the connection between pipeline 23 and constant pressure valve 4 has certain tilt with horizontal axis direction in the horizontal plane
Angle so that conversion both vertically as well as horizontally need to be only realized between pipeline 1 and pipeline 23 by a pipe joint connection,
Avoid needs to connect the problem of causing poor sealing by two pipe joints between existing pipeline 1 and pipeline 23.
Embodiment 2：
Present embodiments provide a kind of associated gas recovery device, including well logging valve 1, pipeline 1, pipeline 23 and constant pressure valve
4, the pipeline 1 and pipeline 23 are retractable structure, the connection between the pipeline 23 and constant pressure valve 4 in the horizontal plane with
