In the test, mainly, a lower choke plug is connected with a sleeve barrel in which a spring is arranged through screws; then, a floater is placed in a lantern body, both ends of which are conical structures; the upper part thereof holds right a floater rod through a holding ring; the floater is connected with the floater rod through screw threads; the upper part of the floater rod is sheathed with soft magnetic materials which are in a coil; the spring on the lower part of the floater rod positions the floater in the middle position of the lantern body; a sealing ring is arranged in a sealing joint; the sealing joint is connected with a coil rack through screw threads. A circuit board is fixed on a circuit board rack in a circuit board barrel, and a circuit board rack is connected with an adapter through screw threads to form the tester. The utility model, which solves the problem that a float flowmeter can not measure bidirectional flow in the prior art, can be widely applied to the flow quantity test of the production profile and the injection profile of an oil well.
Description
Technical field:
The utility model relates to a kind of bidirectional flow float flow tester that a kind of production profile of oil well and input profile flow rate test are used.
Background technology:
The flow tester that present oil field is used mainly is the traffic logger that adopts turbine flow transducer, because the characteristics of turbo flow meter self structure make its fluid viscosity very responsive, is difficult to produced-water reinjection well, light viscous crude, high-solidifiability oil well are effectively measured.The similar well in the whole nation occupies very at high proportion, and the main flow tester of using at present of making by the float flow sensor parts influence that flow measurement causes can overcome fluid viscosity preferably the time, but, this flow tester can only be surveyed the fluid of single flow direction, can not survey the fluid of two-way flow.And in the oil well phenomenon that fluid flows backwards appears often in fact, therefore, need a kind of tester that can measure the fluid flow of different flow directions simultaneously of development.
The utility model content:
In order to overcome that existing flow tester can only be tested the fluid of single flow direction and the deficiency that can not survey the two-way flow fluid, the utility model provides a kind of bidirectional flow float flow tester.
The technical scheme that the utility model technical solution problem is adopted is: with lower end cap and innerspring sleeve screwed connection, be provided with centering ring in upper cartridge, to set upright float lever, the lantern body two ends are pyramidal structure, float is threaded with float lever, be with soft magnetic material on float lever top, soft magnetic material moves in test coil, and test coil is wrapped on the coil former (making with titanium steel).The spring of float lever bottom makes float be positioned at the centre position of lantern body; Be provided with O-ring seal in sealing adaptor, sealing adaptor is threaded with coil former, and the two makes coil with outside isolated; Wiring board is fixed on the interior circuit grillage of breadboard tube, and the circuit grillage is threaded with X-over.What the displacement measurement of float adopted is the principle of inductance type transducer, when soft magnetic material moves in coil, the inductance of coil changes, and induct and the electromotive force of secondary coil also change, so can determine the displacement situation of float by the variation inductance amount.Lantern body is used to protect float, and fluid is circulated smoothly, and the centering ring at two ends is used for making float protection center condition.Float will move to fluid flow direction when fluid flow increases, and also move because the motion of float drives the soft magnetic material on float lever top, can determine the motion conditions of float and then the flow of definite fluid by the variation of test induced electromotive force.Do not contact with float owing to measure coil, float can adopt the different different shapes of material according to the needs of measuring.Can adjust the measurement range and the measuring accuracy of instrument easily by changing different floats and spring.Metering circuit: oscillating circuit produces sinusoidal ac signal, provides alternating voltage to primary winding; Induced voltage proportional variation that secondary coil produces with the change in displacement of float, induced voltage is delivered to signal processing circuit after exchanging amplification; Induced voltage after signal processing circuit will be amplified changes frequency signal into.This test circuit is the variation of frequency with the change in displacement of float.
The utility model beneficial effect is, by two springs up and down float is equilibrated at the centre position of this instrument in this tester,, under the situation of identical float displacement, has increased the test specification of flow owing to be provided with spring, can survey the fluid of two-way flow, and good test effect; Float exposes in outside easy-maintaining of instrument and maintenance; Easily change float and spring; Flow rate test precision height.
