Abstract
The utility model relates to a gas and sand separator for natural gas wells, and belongs to the ground gas-oil separator device class of oil-gas wells. The gas well of the prior art frequently has desilting granules, which causes the gas well to stop in the production process. The utility model uses a method that a vortex separator is arranged in a tank body of the separator, the gas and the sand grain in the well are separated, the sand grain enters the desilting tank body along a connection opening of a sand exhaust pipe, the sand contained in the gas is thoroughly separated off and the sand grain has no damage function on pipelines and gas mouths of ground flow paths. In addition, the utility model can continuously work when used for the production of the gas well, the sand is periodically exhausted, and the continuous production of the sand-outlet gas well can be realized. As the structure is simple, the utility model can be widely used for removing sand for the sand-outlet gas well.
Description
Technical field:
The utility model relates to a kind of natural gas gas well gas sand separator, belongs to oil gas well ground Oil-gas Separation apparatus class.
Background technology:
Oil well in process of production, can often run into especially and contain the sand gas well, this well is in process of production because the erosion meeting of stratum output sand causes the ground flow valve that the abrasion distortion takes place, to occur the flow process abrasion when serious and cause hole, at present, cause gas well not produce owing to lacking the gas well desanding device.
The utility model content:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of natural gas gas well gas sand separator that provides can be realized natural gas and output sand to separate when this device is used for the natural gas well head, can guarantee the continuous ordinary production of gas well again.
The utility model is that implementation is: the mouth of pipe of giving vent to anger, the air inlet mouth of pipe that are connect above by eliminator tank body and eliminator tank body thereof of the utility model formed in order to achieve the above object.The position is connecting a sand setting tank body with the sediment outflow interface tube under the described tank body, between eliminator tank body and sand setting tank body, welding a bypass pipe, in the described separation tank body cyclone separator is housed, this cyclone separator is to be shaped as funnelform inner core with what 16 manganese metal materials were made, and its inner core inner wall surface scribbles one deck compound resin coating.
Described sand setting tank body interior shape is fan-shaped cone, and its scallop and tank body base angle are 30 degree.
The utility model is to realize like this.
The utility model is installed in the well head flow process of ground.The inlet natural gas pipeline is connected on the air inlet mouth of pipe by flange with pipeline, the interior natural gas of well this moment enters in the interior cyclone separator of eliminator tank body, in cyclone separator, rotate in the shape of a spiral along inwall, be that 0.05～3 millimeter sand grains footpath sediment outflow interface tube is deposited to gas pure relatively in the sand setting tank body and is then entered in the natural gas line of ground by the mouth of pipe of giving vent to anger thus with particle diameter, owing between eliminator tank body and sand setting tank body, weld bypass pipe, when the oil-sand in the sand setting tank body is difficult for discharging, can be by bypass pipe air scour sediment outflow, when the oil-sand air scour can not can not arranged in the mud settling tank, can open hand hole, carry out manual sand removal.
The utility model compared with prior art has distinguishing feature:
Because this device is connected in the flow process of gas well outlet, like this when the rotational flow separation gas in the gas process gas sand separator of band sand grains in the well, gas can be under cyclonic action can be fast with the sand fallout in the sedimentation gas in the sand setting tank body, can from the sand setting tank body, sand body be removed again then, in addition because bypass pipe also is housed in device, can in the sand setting tank body, be difficult under the discharge situation by oil-sand again, carry out the sand washing sediment outflow by bypass pipe with gas, simultaneously the hand hole in the utility model can be in mud settling tank oil-sand wash away when clean, the time row manual sand removal, this device can thoroughly separate sand grains in the well that contains 0.05～3 millimeter of sand diameter in the gas.
Description of drawings:
Figure is a structural representation of the present utility model.
Among the figure by the mouth of pipe of giving vent to anger 1,, 2, the separator pot mouth, 3, cyclone separator, 4, the air inlet mouth of pipe, 5, return duct, 6, bypass pipe, 7, pressure meter, 8, the sand setting tank body, 9, hand hole, 10, sediment outflow interface tube, 11, support, 12, safety valve, 13, sediment outflow interface tube, 14, blow-down pipe interface, 15, safety valve, 16, the discharging tube interface forms.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the mouth of pipe 1 of giving vent to anger is installed in the top of eliminator tank body 2, clean air after separating can be flowed out from the mouth of pipe, the cyclone separator 3 that is equipped with in the eliminator tank body 2 is to be shaped as funnelform inner core with what 16 manganese metal materials were made, the inner wall surface of this inner core scribbles one deck compound resin coating, the air inlet mouth of pipe 4 is connected the side of eliminator tank body 2 and links with tank body 2, its effect is that the natural gas in the gas well is entered in the eliminator tank body 2 through this mouth of pipe, bypass pipe 5 is welded between eliminator tank body 2 and the mud settling tank 8, when oil-sand row is clean in the mud settling tank, can not carry out the gas sediment outflow with bypass pipe 5, return duct 6 is used for the backflow of branch tank body 2, pressure meter 7 is used to refer to the gas pressure in the sand setting tank body 8, hand hole 9 is the circular hole that can open closure that is installed in sand setting tank body 8 outer walls, by hand the sand grains in the sand setting tank body is pulled out by discharge orifice, sedimentation tank body 8 interior shapes are fan-shaped cone, and its fan-shaped one side is 30 degree with tank body base angle.Sediment outflow interface tube 10 can be discharged the sand grains in the sand setting tank body 8, and sediment outflow interface tube 13 is that a round mouth pipeline is communicated with eliminator tank body 2 with sand setting tank body 8.Discharging tube interface 16 effect is that the fluid in the oil-sand is therefrom discharged.
