For achieving the above object, a kind of winter length of preventing pays close attention to well pipeline bursting by freezing device, and feature exists In, comprising:

Pipeline connects mechanism and pipeline plugging mechanism；

The pipeline plugging mechanism in winter when closing well, is linked into apart from the ground at least 1500mm water filling below On well lines, for blocking the ground lower interface of the water injection well pipeline, the water injection well pipeline bursting by freezing is prevented；

The pipeline connects mechanism, when the water injection well is gone into operation, replaces the pipeline plugging mechanism, is used for the water filling The connection of well lines restores the normal operation of water injection well.

Preferably, the pipeline connects mechanism, comprising:

First flange disk, second flange disk and pipeline pipe nipple；

The first flange disk and the second flange disk are separately fixed on the water injection well pipeline；

Lower annular groove and upper annular groove are respectively provided on the opposing end surface of the first flange disk and the second flange disk；

The two-port of the pipeline pipe nipple is inserted respectively into the upper annular groove and in the lower annular groove；

Bolt is connected between the first flange disk and the second flange disk；

The bolt, for the pipeline pipe nipple to be fastened between the first flange disk and the second flange disk.

Preferably, the pipeline plugging mechanism, comprising:

Block ring flange；

It is bolted between the closure ring flange, with the second flange disk, for blocking the water injection well pipeline Ground lower interface.

Preferably, there is annular ridge on the lower end surface for blocking ring flange；

The annular ridge, it is corresponding to the upper annular groove on the second flange disk, for sealing the water injection well The ground lower interface of pipeline.

The utility model has the following beneficial effects:

Prevention winter of the utility model long concern well pipeline bursting by freezing device is mounted below the regulating gate of inflow direction, Winter freezes on layer water injection well pipeline below, and pipeline plugging mechanism therein in winter when closing well, can block water injection well pipeline Ground lower interface, prevent water injection well pipeline bursting by freezing；When water injection well is gone into operation, mechanism is connected using pipeline and replaces pipeline stopple plugging machine Structure, water injection well pipeline connection, restores the normal operation of water injection well.As can be seen that the prevention winter long concern well pipeline bursting by freezing The application of device, for reducing the workload of oil recovery work area maintenance mans, pre- minister of defense pays close attention to the bursting by freezing of well pipeline and equipment is freezing, no It influences periphery water injection well normally to produce, guarantees that environment is not contaminated and play crucial effect, while reducing because of pipeline bursting by freezing shadow Ring loss caused by production.
