Description
Technical field
The utility model relates to oilfield gas production measuring equipment, especially a kind of oil well gas production self-measuring device.
Background technology
Existence always along with natural gas in oil extraction process, the change of tolerance is the important content of oil well output change.Traditional oil gas metering mode adopts gs-oil separator, and oil-gas mixture to carry out the size of tolerance in liquid according to time in gas hydraulic fluid face again after gas-liquid separation by manually calculating rough producing well, low gas well, without gas well operating difficulties.In recent years, the metering method of " oil well indicator card gauging " obtains large-area applying, but which cannot realize the accurate-metering of gas production, brings a new difficult problem to WPA and block geological analysis.The oil gas water multiphase measurement device that present stage abroad adopts is mostly bulky, and cost intensive is difficult in maintenance, and is not suitable for well mouth of oil well use.
Summary of the invention
The purpose of this utility model is to provide a kind of oil well gas production self-measuring device, and easy to operate, structure is simple, be convenient to safeguard, economical and practical.
The purpose of this utility model realizes by following technical measures:
This oil well gas production self-measuring device comprises main pipeline, the upper and lower both sides of described main pipeline are each opens a bypass pipe, wherein the bypass pipe of bottom is flow channel for liquids, the bypass pipe of upside is gas flow, the front port of described main pipeline arranges gas-liquid cyclone separator, arrange one in described gas flow stretch to and towards the wireway of gas-liquid cyclone separator, the bypass pipe of described upside also arrange gas volume flow gauge.
The purpose of this utility model also realizes by following technical measures:
Outside described wireway and between main pipeline inwall, there is gap, this gap be pendular ring pass through gap.
Also arrange second-stage separator in the bypass pipe of described upside, described wireway is connected to second-stage separator front end, and gas volume flow gauge is arranged on the rear of second-stage separator.
The top of described second-stage separator increases at least one group of silk screen fine separator.
Described second-stage separator top increases at least one deck drop screen pack.
Compared to prior art, the utility model has following beneficial effect:
1, metering device volume is little, dependable performance, convenient operating maintenance, is applicable to oil well mouth and uses.
2, metering process is simple, moderate cost, and measuring accuracy is high, and low-carbon environment-friendly, pollution-free, field produces needs can be met, at industry measurement system regions, there is larger promotional value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1 is gas-liquid cyclone separator; 2 is wireway; 3 is second-stage separator; 4 is gas volume flow gauge.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
With reference to accompanying drawing 1, oil well gas production self-measuring device, comprise main pipeline, the upper and lower both sides of described main pipeline are each opens a bypass pipe, wherein the bypass pipe of bottom is flow channel for liquids, and the bypass pipe of upside is gas flow, and the front port of described main pipeline arranges gas-liquid cyclone separator 1, arrange one in described gas flow stretch to and towards the wireway 2 of gas-liquid cyclone separator, the bypass pipe of described upside also arrange gas volume flow gauge 4.Outside described wireway and between main pipeline inwall, there is gap, this gap be pendular ring pass through gap.Also arrange second-stage separator 3 in the bypass pipe of described upside, described wireway is connected to second-stage separator front end, and mass-flow gas meter is arranged on the rear of second-stage separator.
First by the novel gas-liquid cyclone separator of appropriate design, gas and liquid are separated under the influence of centrifugal force in pipeline, by the air accumulation of dispersion to pipeline center region, liquid becomes pendular ring around gas karyomorphism, both walk abreast and flow and do not mix mutually in pipeline, and after one-level is separated, liquid directly switches to downstream.With wireway gas and the circumnuclear a small amount of liquid of gas imported in secondary gas-liquid separator in the lump and carry out the second-order separation, the screen pack of several groups of silk screen fine separators or other form is increased on the top of eliminator, so that filtering fine drop, measures to obtain volumetric flow of gas finally by volumetric flow of gas further.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
