Description
Technical field
The utility model relates to a kind of oil production equipment, particularly a kind of oil extraction metering device.
Background technology
In the crude oil transmission measurement flow of ground, oil field, generally adopt the metering device of flow meter as crude output, simultaneously, for preventing that oil-well drainage from carrying out the impurity of greater particle size in liquid and entering flow meter, strainer was often installed before flow meter, to reduce the damage probability of flow meter, is reduced error in dipping.At present, due to Oilfield using water mixing companion thermal flow process, the incrustation scale that in manufacturing process, high temperature produces, and the rust deposite that after long-time production, oil pipe produces and down-hole go out the impact of the factors such as husky, single filter significant discomfort that oilfield metering station uses is answered produced on-site needs, poor filtration effect, cause thus Causing Flowmeter Damages, the problems such as error increase, reduce the accuracy rate of data admission, cause greater loss to production, and maintenance activity is frequent, cleaning filter workload is large, execute-in-place labor strength is large, producing well pressure is large, oil sample sampling gage work complexity, sample inhomogeneous, affect the calculating of oilwell produced fluid amount.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of oil extraction metering device is provided.
Its technical scheme is: comprise metering body, flange, bolt, the two ends of metering body are bolted flange, it is characterized in that: the upper surface of described metering body is provided with high-pressure sampling mouth and low pressure sample tap, described high-pressure sampling mouth connects high-pressure sampling pipe, described low pressure sample tap connects low pressure probe tube, described high-pressure sampling pipe is connected differential pressure transmitter with low pressure probe tube, the inside stationary wedge of described metering body is measured body, described wedge shape is measured the tapered structure of body, wedge shape is measured body and is comprised clapboard, described clapboard is provided with metering orifice, the inside that wedge shape is measured body is provided with flow transmitter, described flow transmitter comprises housing, the front end of housing is provided with inlet opening, the rear end of housing is provided with fluid hole, the side, rear end of housing is provided with gear liquid lobe, housing is provided with liquid outlet, described liquid outlet is communicated with differential pressure transmitter.
The bottom angle of taper that described wedge shape is measured body is 60 degree.
