Preferably, described cylinder body bottom is 9mm-11mm with the distance of measured hole.

Preferably, described cylinder inboard wall thickness is 0.8-1.1mm.

Preferably, also including gamma-rays monitor, described measured hole is just installed by it.

The beneficial effects of the utility model are:

This utility model has designed and developed a kind of device demarcated for multi-phase flowmeter, inserts and makes inside Venturi tube With, in solving venturi chamber, fluid cleans inconvenient problem, and reduces testing sample demarcation volume, simple in construction, Handling ease, service life is long, treats that standard specimen product need volume few, and compared with the prior art, required sample is only original six / mono-, demarcate appearance and be easily achieved.

Accompanying drawing explanation

Fig. 1 is the structural representation of the device demarcated for multi-phase flowmeter described in the utility model.

Fig. 2 is caliberating device scheme of installation described in the utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art with reference to explanation Book word can be implemented according to this.

As it is shown in figure 1, the device demarcated for multi-phase flowmeter that this utility model provides, it is characterised in that including:

Cylinder 100, its inner hollow, sealed bottom, cylinder 100 outer wall is provided with column-shaped projection, is close to venturi tube chamber Chamber interior walls uses, and plays centralizing function placed in the middle；

Measured hole 200, its quantity is two, is arranged on bottom cylinder 100, and measured hole 200 is about faced by cylinder 100 axis Claim distribution, it is possible to make gamma-rays pass testing sample；

Identification hole 300, its quantity is two, is arranged on cylinder 100 top, becomes axis to be distributed with measured hole 200, when two When identification hole line and gamma activity source, gamma-rays monitor line coincide with the upper and lower, it becomes possible to gamma-rays of going bail for is worn without being blocked Cross and treat standard specimen product, without being stopped by demarcating cylinder cylinder body outer wall.

Seal washer 400, it is " O " type, is arranged on bottom cylinder 100, it is possible to prevent downhole fluid from missing to measuring chamber Bottom.

Preferred as one, barrel diameter is 28-30mm, and cylinder body bottom is 9mm-11mm with the distance of measured hole, cylinder Inner wall thickness is 0.8-1.1mm.

Gamma-rays monitor 500, measured hole 200 is just installed by it.

As in figure 2 it is shown, as a example by implementing the work process of the device for multi-phase flowmeter demarcation, make further Bright:

First computer is connected with multi-phase flowmeter, starts multi-phase flowmeter Survey Software.

Cleaning Venturi tube and caliberating device inwall, insert caliberating device in Venturi tube, clicks on mouse and chooses demarcation Menu, record cleans forward and backward gamma-rays monitor 500 count value respectively, when cleaning forward and backward gamma-rays monitor 500 count value Time basically identical, complete multi-phase flowmeter blank pipe and demarcate, i.e. record gamma-rays monitor 500 passes the attenuation rate after blank pipe.

Pouring the diluter sample to be calibrated of 30cc (water) into, liquid level exceedes measured hole 200, and record gamma-rays monitor 500 passes Attenuation rate after sample.

Extract caliberating device, remain in Venturi tube intracavity sample and rely on self gravitation, flow in T-shape blind pipe.

Cleaning Venturi tube inner chamber and caliberating device, pours 30cc into compared with thickness sample to be calibrated (oily), and liquid level exceedes measurement Hole, record gamma-rays monitor 500 passes the attenuation rate after sample.

Clicking on mouse, select demarcation to terminate, computer software automatically generates solution triangle with oil gas water as summit respectively Shape.

It is directed into multi-phase flowmeter producing relief line, starts oil-gas-water three-phase metering, according to measuring point at triangle In position, calculate the respective one after another of three-phase.

The total flow asked in conjunction with Bernoulli equation and one after another data, calculate the yield of oil gas water three phase.

Caliberating device inserts the internal use of Venturi tube, and in solving venturi chamber, fluid cleans inconvenient problem, And reducing sample volume to be calibrated, simple in construction, handling ease, service life is long, treats that standard specimen product need volume few, and Having technology to compare, required sample is only original 1/6th, and demarcation is easily achieved.

Although embodiment of the present utility model is disclosed as above, but it is not restricted in description and embodiment Listed utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, It is easily achieved other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, this reality It is not limited to specific details and shown here as the legend with description with novel.
