Abstract
The utility model discloses a natural gas well desanding device which is designed for preventing gravel from eroding pipe walls and preventing pipelines from being blocked due to freeze. A desanding barrel of the natural gas well desanding device is arranged on a support, the two ends of the desanding barrel are connected with a mixed gas inlet flange and a desanding port flange cover respectively, a pressure relief opening is formed in the top of the desanding barrel, a gas-liquid outlet is formed in the bottom of the desanding barrel, the gas-liquid outlet is connected to a gas-liquid outlet flange through an elbow, a filter cartridge which is supported by a guide rail and arranged horizontally is arranged in the desanding barrel in a sealing mode, and the two ends of a suspending rod are connected to the top surface of the desanding port flange cover and the side face of the desanding barrel respectively. The natural gas well desanding device can filter out sand carried by gas moving at high speed in a natural gas well, bring liquid out of the device, the gravel is prevented from eroding and damaging the pipelines, the device is prevented from being blocked due to the freeze, and continuous safe production of the gas well is guaranteed.
Description
Technical field
The utility model relates to a kind of natural gas well desanding device, belongs to natural gas production technical field.
Background technology
In current natural gas is produced, because technique needs, must inject a large amount of fracturing sands in operation forward direction down-hole and carry out Fractured Gas Wells.After the natural gas well is gone into operation, fracturing sand enters pipeline with natural gas from down-hole again, and high-speed motion in pipeline washes away tube wall and elbow, causes pipeline walls thorn to leak, and causes the potential safety hazard of leakage or blast.Meanwhile, natural gas takes under ground portion moisture to surface line, in the time of high pressure and certain low temperature, generates gas hydrates, can produce frozen block, and sealing blocks pipeline, causes natural gas damp production.Although common strainer can filter sand, due to structure, in the time of filter sand, part water is also retained down, form hydrops, cause frozen block.
Summary of the invention
The purpose of this utility model is to provide a kind of natural gas well desanding device, washes away tube wall to reduce gravel, prevents pipeline frozen block.
Concrete technology contents of the present utility model is as follows:
The desanding cylinder of this desanding device is located on support, and desanding cylinder two ends connect respectively combi inlet port flange and desanding mouth blind flange, and desanding cylinder top is provided with pressure relief opening, and bottom is provided with gas liquid outlet, and gas liquid outlet connects gas liquid outlet flange by bend pipe; In desanding cylinder, sealing arranges by cartridge filter guide supporting, horizontal positioned; Suspension rod two ends connect respectively desanding mouth blind flange end face and desanding cylinder side.
This desanding device can be taken sand by the gas of natural gas well high speed operation and filter out, and takes liquid out of device, thereby avoids gravel to wash away and injure pipeline, and frozen block in anti-locking apparatus guarantees gas well production safely continuously.

The specific embodiment
Embodiment:
Further illustrate referring to figs. 1 through 3 couples of embodiment of the present utility model:
This desanding device comprises combi inlet port 1, gas liquid outlet flange 2, desanding cylinder 3, pressure relief opening 4, cartridge filter 5, desanding mouth blind flange 6, guide rail 7, gas liquid outlet 8, support 9 and suspension rod 10;
Desanding cylinder 3 is located on support 9, and desanding cylinder 3 two ends connect respectively combi inlet port flange 1 and desanding mouth blind flange 6 by bolt, and desanding cylinder 3 tops are provided with pressure relief opening 4, and bottom is provided with gas liquid outlet 8, and gas liquid outlet 8 connects gas liquid outlet flange 2 by bend pipe.The interior sealing setting of desanding cylinder 3 is by guide rail 7 cartridge filter 5 that support, horizontal positioned.Suspension rod 10 two ends connect respectively desanding mouth blind flange 6 end faces and desanding cylinder 3 sides.
Mist enters the cartridge filter 5 that is positioned at desanding cylinder 3 through combi inlet port 1 level, cross filter sand and be trapped within cylinder, and gas and water flow out by gas liquid outlet 8, enter next stage pipeline.Because gas liquid outlet 8 is positioned at the minimum point of desanding cylinder 3, thus in device, can not retain hydrops, thus can avoid frozen block to occur.When stopping production, open desanding mouth blind flange 6, extract cartridge filter 5 out, remove gravel in cylinder, then, then cartridge filter 5 is put back in desanding cylinder 3, continue to use.
