Abstract

The utility model relates to a bergol oil well metering device, which is composed of a separate measuring tank of a mechanical part and a common control circuit, wherein, the separate measuring tank is composed of an oil inlet and a separator on the upper part, a hopper on the lower part, a tipping bucket on the middle part, and a heat tracing pipe and an oil outlet on the lower part. The control circuit is composed of a programmable controller and a metering sensor, a temperature sensor, a content gauge, a transducer, a display header, an input key-press and a position switch. The flow capacity of the oil is calculated by the programmable controller, a metering sensor and a temperature sensor. The utility model has advantages that the sealing property of the metering tank is good with convenient operation, and the utility model mndel is an electromechanical integration commodity. The sealing property of the utility model can save a great amount of thermal energy, which relieves pipeline pressure; and the horizontal metering used by the artificial metering can be replaced, which solves the present status that the artificial metering is of great difficulty with and wasted labor and time.

Description

Weighing type oil well measurement device

Technical field

The utility model relates to a kind of oil well measuring apparatus, is adapted at using in the oil gas-oil separation process.

Background technology

At present, the employing Skip meter is arranged in oil production rate computation process, CN2488049Y is exactly one kind of in prior art, mainly utilize the metering of mechanical hook-up realization to the oil flow, advantage is simple in structure, it is also comparatively convenient to install and use, it is to measure oil flow by turning over half, be suitable for low permeability oil field, its weak point is: because viscous crude is sticking, easily stick on the tipping bucket wall, and the viscous crude gassiness is difficult for discharging, therefore it is bigger to measure the viscous crude time error, is unsuitable for heavy oil metering.

Summary of the invention

For solving the deficiency of above technology, the purpose of this utility model provides a kind of Weighing type oil well measurement device, utilizes tipping bucket and general purpose control circuit programmable controller to combine, to realize the accurate Calculation to oil flow.

The structural design of the utility model is achieved in that its structure of this Weighing type oil well measurement device forms (as shown in Figure 1) by separate measurement jar and universal control circuit two parts of mechanical part, wherein separate measurement jar outside is a tank body, the tank body top is an oil-in, liquid level gauge is equipped with at the oil-in place, separation vessel vertically is housed below the oil-in, corresponding with separation vessel is hopper, fix by support and both sides, tipping bucket is housed below the hopper, and wherein tipping bucket is made up of two independent hoppers of symmetry, LOAD CELLS is housed below the tipping bucket, intermediate lateral is placed with rotating shaft, fix by tipping bucket support and both sides, tank base is equipped with trace pipe, and the side has oil-out; Control circuit is made up of Programmable Logic Controller, weighing sensor, temperature sensor, liquid level gauge, transmitter, display gauge head, position switch and input button, be all the standardized component of selling on the market, its connection is Programmable Logic Controller input end and temperature sensor; Liquid level gauge position switch and transmitter are parallel to be connected, and the LOAD CELLS output terminal connects with transmitter, and the transmitter output terminal connects with display gauge head, and Programmable Logic Controller output and input are by key connecting.

The advantage of the utility model: this meter good seal performance, easy to operate, be electromechanical integrated product, the sealing property that it has is saved a large amount of heat energy and is alleviated pipeline pressure, and can replace the leveler measuring tank that adopts human metering to use, solved the present situation that the human metering difficulty is big, waste time and energy.

Embodiment

This Weighing type oil well measurement device and principle of work are described in detail in conjunction with the accompanying drawings.

In the porch of oil well measurement device one umbrella separation vessel is installed, is made crude oil after separation vessel spreads out, flow to tipping bucket, reach the purpose that oil gas partly separates with this through hopper.LOAD CELLS is installed on the tipping bucket, eliminates by crude oil is weighed because the long-pending measuring error of bringing of the prosthese that gassiness causes in the oil.Bucket-tipping device is made up of two independent hoppers of symmetry, detection obtains a time dependent curve of weight through LOAD CELLS, according to the weight change rule, utilizes integral and calculating can obtain integrated flow, and then be converted into output, thereby get rid of the measuring error that the sticking bucket of viscous crude brings.

The electrical system of operation circuit is a core with the PLC Programmable Logic Controller, adopts process variables such as LOAD CELLS, liquid level gauge, temperature sensor, obtains interior production fluid amount of a certain period through integral and calculating, and then is converted into day output.

This meter has reached the purpose that viscous crude oil gas partly separates owing at the crude oil import place oil-gas separator has been installed; Owing on the tipping bucket LOAD CELLS is installed, by weighing crude oil is measured, therefore eliminated the long-pending error in dipping that brings of the prosthese that causes owing to gassiness in the oil; Detect the time dependent curve of weight that obtains according to LOAD CELLS, utilize integral and calculating to obtain integrated flow, and then be converted into output, thereby get rid of the measuring error that the sticking bucket of viscous crude brings; This meter is oil-collecting gas separation function and function of measuring individual well liquid producing amount measure device, and the viscous crude gassiness is difficult for discharging and viscous crude is stained with the error that bucket causes owing to can eliminate, and therefore is fit to heavy oil metering and measuring accuracy height; Utilization is that the electrical system of core and separate measurement constitute the complete separate measurement supervisory system of a cover with the PLC Programmable Logic Controller, has real-time status demonstration, historical record, starts and stop function such as measurement.
