Abstract

The utility model relates to an underground water filling flowmeter for oil fields. A metering mechanism and a counting mechanism are arranged in a casing; the casing is in a sliver shape, and the upper part of the casing is provided with a water inlet. The metering mechanism is fixedly connected by an impeller and an impeller shaft, and one end of the impeller shaft is provided with a worm; the counting mechanism is composed of a plurality of gears sets with gear driving ratio, pointers and dials, wherein, the gears sets, the pointers and the dials are connected with each other, wherein, the first set of gears are in mesh through a worm wheel and the worm, and the rest gear sets are connected with the pointers. The utility model overcomes the defects of short working time, complex operation and complicated structure existing in a float meter. The utility model has the advantages of convenient operation, rapid reading and long working time, and is an ideal underground water filling flowmeter for oil fields.

Description

Oil field underground water-injection flow meter

The utility model relates to a kind of oil field underground water-injection flow meter.

The oil field underground water-injection flow of known use is counted float-type flowmeter, during its work, drives paper tape by clockwork spring by reduction gearing mechanism and rotates, simultaneously, the upper-lower position of instantaneous delivery decision float, the position of float is recorded on the paper tape by paintbrush, and there is following defective in this working method:

1, can not directly continue integrated flux, need just can draw final data after calculating, execute-in-place is comparatively loaded down with trivial details.

2, can not work long hours, generally can only write down the flow situation in 24-72 hour.

3, structure is complicated, and cost is higher, and precision is low

The purpose of this utility model is exactly to overcome the above-mentioned defective of common suspended body flowmeter and provide a kind of easy to operate, and is simple in structure, the oil field underground water-injection flow meter that can work long hours.

The utility model comprises metrological service and counting mechanism, metrological service is arranged in the housing, housing (1) is provided with water inlet, metrological service comprises impeller and impeller shaft, impeller and impeller shaft Joint, one end of impeller shaft is provided with worm screw, counting mechanism is by some interconnective, gear train, pointer and dial with gear ratio constitute, and be arranged in the clamping plate (9) of a strip, wherein first group of gear is that worm gear is meshed with the worm screw of impeller shaft end, and all the other gear trains are connected with pointer.By said structure, whole flow meter can fuse by screw thread and water distribution tubing string, during metering, is put into the down-hole with the water distribution tubing string, salvages during reading again.

Below in conjunction with drawings and Examples detailed content of the present utility model is described.

Accompanying drawing is a structural representation of the present utility model.

As shown in the figure, the utility model comprises metrological service and counting mechanism, metrological service is arranged in the housing (1), housing (1) is provided with water inlet (10), metrological service comprises impeller (2) and impeller shaft (3), impeller (2) and impeller shaft (3) Joint, end at impeller shaft (3) also is provided with worm screw (4), counting mechanism is by some interconnective, gear train (5) with gear ratio, pointer (6) and dial (7) constitute, and are arranged in the clamping plate (9) of a strip, wherein first group of gear is that worm gear (8) is meshed with the worm screw (4) of impeller shaft end, and all the other gear trains are connected with pointer (6).In order not make the impurity in the current enter counting mechanism, magnetic shaft coupling (11) can be set also under worm screw (4).When current flow into from the water inlet (9) on the housing (1), behind rectifier (1), impact the blade of impeller (2), worm screw (4) rotation that promotes impeller (2) and be connected with impeller (2).(angular velocity and the flow rate of fluid of impeller rotation are proportional).Worm screw (4) drives interconnective by worm gear (8), have the gear train (5) of respective gears gearratio to rotate, like this, just can with pointer (6) that gear train (5) is connected in directly read the integrated flux of flow path flow meter.

The utility model has been simplified the operation of flowmeter greatly by above-mentioned concrete structure Process, have simple in structure, lower-cost advantage, simultaneously, the utility model can In underground work, be a kind of desirable underground flooding flowmeter for oil field for a long time.
