Abstract
The utility model relates to an optical fiber testing flow rate device, which belongs to the oil well tester class and comprises an apparatus shell and a turbine; wherein the shell is provided with a coded disc and an optical fiber, while the turbine is arranged in the testing shell; when in operation, the liquid flow in the oil well impulses the turbine to drive the coded disc to rotate; and due to the coded disc is provided with a raster, the flow rate has something to do with the intensity of the reflected light penetrating through the grating window; the reflected light is incapable of penetrating through in the place without the grating window, and the light signal neither can be received by the ground; therefore, the flow rate can be distinguished according to light intensity. The utility model is simple in structure and free from the high temperature oil well testing influence particularly, thus promoting the measuring precision.
Description
Technical field:
The utility model relates to a kind of test optical fiber flow apparatus, belongs to oilfield testing arrangement class.
Background technology:
After bringing in, to carry out dynamic test to oil well, in time understand the oil well productivity situation of change, wherein flow rate test is an important parameter of production profile of oil well annular space log, traditional measurement adopts turbine flowmeter to utilize cable by the electronic surveying mode, can only measure temperature and pressure and change, can't carry out the measurement of data on flows, make troubles for the admission data.
Summary of the invention:
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of test optical fiber flow apparatus that provides can utilize optical fiber to combine the flow rate test that carries out oilwell produced fluid amount with turbine.
Technical solutions of the utility model:
For realizing above-mentioned task, the utility model has adopted the device of being made up of tool housing and turbine for this reason, and code-disc and optical fiber are housed in the described shell; Turbine is placed in the test housing.
Permanent magnet all is equipped with at turbine wheel shaft one end and the code-disc two ends of described turbine top, and described code-disc is in the form of annular discs, and periphery has the grid window and is made with metal or resin plate material.
During work, by optical cable the optical fiber measurement device is lowered in the oil well, keeps apart with turbine because tool housing is contained in code-disc and optical fiber in the housing, turbine is exposed in the oil well inner fluid, and an end of turbine wheel shaft is equipped with permanent magnet.Position in tool housing inside over against turbine is equipped with code-disc, and permanent magnet is also arranged on the code-disc, when turbine because during the impact of fluid rotation under the sucking action of code-disc at permanent magnet and rotate synchronously, because of the grid window is housed on the code-disc with turbine.The optical signal on ground is by fiber-optic illuminated on code-disc, in the code-disc rotary course, behind light transmission grid window, be radiated on the reflecting surface again, this reverberation is passed ground back by optical fiber then, and in the position that does not have the grid window, light then can't be radiated on the reflecting surface, so ground also just can not receive catoptrical signal.
If secondary speed is fast, show the flow rate of liquid height, then the reflecting light on reflecting surface is just strong, otherwise then, illustrates that the low photosignal of flow velocity is input to ground by optical fiber and measures, just how much know the interior fluid flow of well.
The utility model compared with prior art has distinguishing feature:
Because this device has utilized interior optical fiber of Instrument shell and the turbine structure in code-disc and the measured fluid, cause measurement liquid can drive turbine rotation, turbine is by the magnet effect, code-disc is rotated synchronously, to shine code-disc grid window upper rim ray intensity and constantly change, thereby this device can make and utilizes the optical fiber measurement fluid flow to become a reality with changes in flow rate.
Description of drawings:
Fig. 1 is the utility model structural representation.Fig. 2 is the code-disc structural representation.
Among the figure by 1, tool housing, 2, permanent magnet, 3, code-disc, 5, turbine, 6, optical fiber, 7, reflecting surface, 8, turbine wheel shaft, 9, the grid windows forms.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
Among Fig. 1, tool housing 1 is elongated metal cylinder body, be placed with code-disc 3 and optical fiber 6 by fixed mount in the body, be used for writing down the variation of fluid flow in the oil well, described code-disc 3 is shaped as discoid, adopt metal or resin material to be made, have the grid window 9 of several different in width in the disc circumference edge part, the code-disc two ends are equipped with permanent magnet 2, code-disc, the effect of grid window and magnet is when the turbine 5 that is arranged in liquid stream rotates under liquid flow impact, by permanent magnet 2 sucking actions code-disc 3 is rotated synchronously, because of grid window 9 is arranged on the code-disc, the optical signal on ground is radiated on the code-disc 3 by optical fiber 6, the code-disc rotation constantly has light transmission grid window to penetrate on reflecting surface 7 during the course, reverberation reaches ground by optical fiber with optical signal again and carries out record, local optical signal can't be radiated at above the reflecting surface in the position that does not have the grid window, just do not receive reflected light signal like this on ground, secondary speed in catoptrical strong and weak and the liquid stream has direct relation, rotating speed is big, reflective light intensity, the ground light signal of telecommunication is just big, and the flow height is described, otherwise then little.
