Description

Wireless liquid level interface instrument

Technical field:

The utility model relates to the production metering of oil wells device, is a kind of wireless liquid level interface instrument.

Background technology:

Oil well output generally adopts volumetric method metering output, and it is higher, fuel-displaced continuously that this measurement Law is fit to output, and water cut, oil gas are more stable; The oil well that viscosity is not high is not suitable for discontinuous fuel-displacedly, and low discharge, water cut, oil-gas ratio are unstable; The oil well that viscosity is high, therefore, the oil field part is discontinuous fuel-displaced; There are the inaccurate and unmeasurable problem of metering in low discharge, water cut, oil-gas ratio instability, the oil well that viscosity is high, can't estimate the economic worth of oil well.One Chinese patent application 201020125577.2 " oil well output weight method WT-MSR " can be to its output of the above oil well measurement, but difficult installation, difficulty of construction is big.

Summary of the invention:

The purpose of the utility model is a kind of wireless liquid level interface instrument of design, makes discontinuous fuel-displacedly, and low discharge, water cut, oil-gas ratio are unstable, and the oil well that viscosity is high can accurately measure.

The purpose of the utility model is achieved in that and comprises storage tank, battery, instrument head, LOAD CELLS, jar mouth, buoyancy tube, resistance wire; Storage tank has a jar mouth, and LOAD CELLS is suspended in jar mouth, and the LOAD CELLS bottom connects buoyancy tube; LOAD CELLS top connects the instrument head; On the instrument head battery is installed, buoyancy tube twines resistance wire outward, and resistance wire is connected with the instrument head through LOAD CELLS.

The beneficial effect of the utility model is: through oil water surface and the liquid level that the resistance that measures buoyancy and the resistance wire of buoyancy tube in storage tank obtains, just can accurately obtain oil well output, be fit to discontinuous fuel-displaced, low discharge, water cut, oil-gas ratio instability; The oil well measurement that viscosity is high, continuous data can be wirelessly transmitted to the receiving end in the office, and the power consumption of battery is few; Therefore, the utility model is when the metering oil well output, and automaticity is high; Do not need external high voltage power supply, the operator is very safe, electric shock accidents can not take place; Thereby safety, convenience, environmental protection, applicability is good, has remarkable economic efficiency and social benefit.

Description of drawings:

Fig. 1 is the wiring layout of the utility model embodiment.

Embodiment:

Below in conjunction with accompanying drawing the utility model embodiment is described.

Can be known that by figure the embodiment of the utility model comprises storage tank 1, battery 2, instrument 3, LOAD CELLS 4, jars mouthfuls 5, buoyancy tube 6, resistance wire 7, storage tank 1 has jar mouthfuls 5; LOAD CELLS 4 is suspended in jar mouth 5; LOAD CELLS 4 bottoms connect buoyancy tube 6, and LOAD CELLS 4 tops connect instrument 3, on the instrument 3 battery 2 are installed; The outer resistance wires 7 that twine of buoyancy tube 6, resistance wire 7 is connected through LOAD CELLSs 4 and instrument 3.

Battery 2 is a dry cell, the use of can charging, and the required electric weight of system is few, does not need external high voltage power supply on the storage tank 1, and the operator is very safe, electric shock accidents can not take place.

The effect of instrument 3 is sensor data acquisition, signal amplification, A/D conversion, data computation, wireless telecommunications.

Storage tank 1 is connected with the oil well flow line, and the fluid of oil well output is stored in wherein.LOAD CELLS 4 can be claimed the buoyancy of its buoyancy tube 6 in the liquid of storage tank 1, and resistance wire 7 has different conductivity in different media, thereby can measure oil water surface; The receiving end that the information that measures is passed in the office by instrument 3; Calculate storage tank 1 stored liquid measure and oil mass by program, the receiving end in the office has data processing, demonstration, memory function, and continuous data directly shows with liquid crystal display; The oil well historical data can store, and makes things convenient for oil well management.Historical data comprises that the entrucking of daily flow and storage tank 1 unloads oil mass.

The data that measure also comprise the temperature and pressure of output liquid.
