Abstract
The utility model relates to the technical field of petroleum and natural gas delivery, in particular to a petroleum and natural gas well filter, which comprises a delivery pipe line, a separator, a sand filter pot, and an air collecting pot that are connected with the delivery pipe line in sequence, and the sand eliminating pipe line that is connected with the bottoms of the sand filter pot and the air collecting pot. A inlet cutting valve, a depress valve and a pressure panel are positioned in the inlet section of the delivery pipe line in sequence; a pressure panel and a outlet cutting valve are positioned in the outlet section of the delivery pipe line. The sand filter pot is composed of the pot body, the sand filter pipe, the explosion-proof valve, the air outlet and the sand discharge outlet. The sand filter pipe comprises a multihole central pipe, a central stainless steel expanded metal, a multihole external protection pipe, a pipe hoop and a plug. The utility model can entirely filter out the dust particles in the natural gas before the gas goes into the delivery pipe line, ensuring the safe operation of the natural gas delivery pipe line. Because the explosion-proof valve is positioned, the safe operation of the sand filter pot can be ensured; and because the separator is arranged in the filter, the oil and air can be separated effectively and the natural gas can be kept pure and clean.
Description
Technical field
The utility model relates to oil, natural gas transport technical field, filter on particularly a kind of oil, the natural gas well.
Background technology
Exploitation is come out from oil, gas field oil, natural gas all have very high pressure, and are mixing many sands.A large amount of sand dusts is particularly arranged in the natural gas.Though when exploitation is come out, passed through filtration, still have some sand dusts to fail to filter out, these remaining sand dusts will cause severe impairment to natural gas transmission pipeline.Because natural gas is to move with very high pressure and speed in feed-line, sand dust with which has very high kinetic energy, therefore can cause very big impact wear to tube wall, particularly tube wall to elbow part, this is fatal to the high-pressure natural gas feed-line, therefore the secondary filter of carrying out that must enter feed-line at natural gas, thoroughly the grit in the filtering natural gas is guaranteed the safe operation of natural gas transmission pipeline.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, filter on a kind of oil of good filtration effect, the natural gas well.
The purpose of this utility model realizes by following technical proposals.
According to filter on oil of the present utility model, the natural gas well, it is characterized in that by transfer pipeline, be connected to separator, filter sand jar, air accumulator in this transfer pipeline in turn, the desanding pipeline that is connected described filter sand jar, air accumulator bottom is formed.
Be provided with the import stop valve in the inducer of described transfer pipeline successively, pressure-reducing valve, Pressure gauge is provided with Pressure gauge, outlet stop valve in the outlet section of transfer pipeline.
Described filter sand jar is set up in parallel the sand screen in this tank body by tank body, is arranged on the explosion-proof valve of this tank body internal upper part, and the sand removing hole at the bottom of being arranged on the exhaust outlet of this tank body upper end and being arranged on this jar is formed, and exhaust outlet is connected with the suitable for reading of sand screen respectively.
Described sand screen by porous central tube, the obstruction that is enclosed within the outer center stainless steel plate mesh of this porous central tube, is enclosed within the outer protection tube of the outer porous of this center stainless steel plate mesh, is connected the pipe collar on the head pipe thread of porous central tube and is arranged on the porous central tube bottom formed, the head of porous central tube has one section imperforate section.
The exit of described desanding pipeline is provided with the outlet stop valve.
Described air accumulator is one or mutual 2-4 air accumulator of connecting.
Described separator is a gs-oil separator.
The jar end of described air accumulator, be provided with sand removing hole, and sand removing hole is connected with described desanding pipeline.
Adopt filter on oil of the present utility model, the natural gas well, the natural gas that contains the sand dust grain enters the natural gas transport pipeline from the import stop valve, reduce pressure through pressure-reducing valve, measure gas pressure by Pressure gauge, through the separator separation oil and gas, the sand screen in the natural gas via filter sand jar of separating filters the back or is sent to natural gas transmission pipeline or is sent to the air accumulator storage through the outlet stop valve.The filtering sand dust enters the desanding pipeline from the sand removing hole that is arranged at the bottom of the filter sand jar jar.
The utility model has the advantages that: can be before natural gas enters feed-line the thorough grit in the filtering natural gas, guarantee the safe operation of natural gas transmission pipeline.Because the tank body internal upper part at the filter sand jar is provided with explosion-proof valve, can guarantee the safe operation of filter sand jar.Owing to be provided with separator, can effectively Oil-gas Separation be opened, guarantee the cleaning of natural gas.
