Description
Technical field
The utility model relates to a kind of natural gas and gathers measurement mechanism.
Background technology
The natural gas resource of China is not very abundant at present; and regional distribution reserves are very inhomogeneous; in recent years along with the fast development of global economy; and the enhancing of earth environment protection consciousness; demand as clean energy resource natural gas increases day by day; gas extraction work is urgent further, and in some hyposmosis areas of China, gas extraction work also is like a raging fire carrying out.If carry out natural gas extraction then need the quantity of the highdensity natural gas well to obtain higher gas production in these areas, several ten thousand mouthfuls of natural gas wells so on an administrative areas at the county level territory, will distribute, because well head quantity is very many, and may be distributed in the Gobi desert, desert, patrol and examine very inconvenience, must carry out the digital network management to the gas field, output, pressure, the temperature of every implication well natural gas are grasped control, the science of carrying out is joined the product exploitation.
At the scene of every mouthful of well except that being furnished with necessary production equipment, wherein the output measuring equipment of natural gas is indispensable, method commonly used at present is, by the full intelligent flow meter installed at the scene under the output metering of individual well natural gas in time rating, teletransmission is to well head RTU, RTU is aggregated into data by wireless DCS system the natural gas processing station of operation area administration more then, upload to the command scheduling center of gas field general headquarters again by treating stations, for producing, the gas field provides technical data, in system, not only to upload flow signal, the operating pressure and the worker's temperature that comprise natural gas also need to upload to the command scheduling center, so also be equipped with gas pressure and temperature pick up on the well head in addition except that flow meter.Because the gas production of individual well natural gas is very low, the input-output ratio of individual well is not good, reduce particularly extremely important that the cost work of natural gas extraction also just shows, the flow meter cost height of intelligent integral itself comprises the compensating element, of temperature and pressure, the verification complexity, the back maintenance cost height that breaks down, this patent is a kind of method of low-cost single well yield metering, reduced pressure, temperature compensation sensor repeat be provided with, improve the overall operation performance, greatly reduced the development cost in gas field.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of well head of natural gas cheaply flow measuring system is provided, and can reduce the construction cost of gas well, the natural gas well well head Flow Measuring System that maintains easily by native system.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of natural gas well head Flow Measuring System, comprise that the gas production pipeline is provided with pressure transmitter and temperature transmitter, and on the gas production pipeline, also be provided with flow meter; Described pressure transmitter and temperature transmitter are arranged on the pipeline in exit of described flow meter; Described flow meter and pressure transmitter and temperature transmitter all are electrically connected with the far-end measurement and control unit device that is used for image data.
Further, described flow is counted the natural gas meter of no temperature and pressure compensation.
Further, described far-end measurement and control unit device is arranged on the pole, and is electrically connected with antenna and solar panel that the pole end is provided with.Solar panel can provide free electric energy for native system.
Further, also include total control computer, described far-end measurement and control unit device is electrically connected with the master control computer radio.
The beneficial effects of the utility model are: the natural gas flowmeter of having used no temperature and pressure compensation in system, only the flow under the natural gas operating mode is measured and with data by the DCS system transmissions, original temperature and pressure sensing data also together is transferred to natural gas processing station, operation area simultaneously, in the control system of the station at natural gas processing station, mechanism according to desirable equation of gaseous state P1V1/T1=P2V2/T2 is calculated, draw the gas discharge under the standard condition, by original be that the component-level of unit is measured to calculate and is improved to system-level measurement and calculates with the well head, because the no longer subsidiary temperature of flow meter, pressure compensation sensor and counting circuit, it is low to have cost, avoid overlapping investment, system is simple, stable performance.
