Summary of the invention
A kind of oil field provided by the invention radio frequency bearing analysis device, this oil field radio frequency bearing analysis apparatus structure is compact, accurate measurement and can reach the effect of on-the-spot individual well continuous measurement.
For solving the problems of the technologies described above, present invention employs following technical scheme:
A kind of oil field radio frequency bearing analysis device, comprising:
Housing;
Enclosure interior is provided with the heart yearn of band pillar, and heart yearn is provided with radio-frequency signal generator, and heart yearn end is connected with probe by connector, and heart yearn top is connected with signal processing unit;
The top of pillar and end seal with housing and connector respectively and connect;
Housing side is also provided with and measures the first flange port that entrance is connected and the second flange port be connected with the well head backflow mouth of oil well surface gathering and transferring pipeline with the well head of oil well surface gathering and transferring pipeline.
Further, described oil field radio frequency bearing analysis device also comprises: the data remote transmitting module be connected with signal processing unit.
Comparatively preferred, described connector periphery is provided with insulation rubber sleeve.
Preferably, described housing bottom is also provided with sample cock.
A kind of oil field provided by the invention radio frequency bearing analysis device, a housing is included in this analyzer of water content, enclosure interior is provided with the heart yearn of band pillar, heart yearn is provided with radio-frequency signal generator, heart yearn end is connected with probe by connector, and heart yearn top is connected with signal processing unit.Wherein, between heart yearn pillar and housing, be formed with wellhead liquid medium circulation passage to be detected, the electromagnetic wave attenuation situation of being launched by monitoring probe can complete the analytic process moisture to wellhead liquid.Therefore adopt that oil field its detection speed of radio frequency bearing analysis device of said structure is more quick, accuracy of detection is also higher.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of oil field of the present invention radio frequency bearing analysis device.
Embodiment
A kind of oil field provided by the invention radio frequency bearing analysis device, this oil field radio frequency bearing analysis apparatus structure is compact, accurate measurement and can reach the effect of on-the-spot individual well continuous measurement.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of oil field radio frequency bearing analysis device, as shown in Figure 1, include housing 1, housing 1 inside is provided with heart yearn 2, and heart yearn 2 periphery is provided with the pillar 3 shielded.Wherein, heart yearn 2 is provided with radio-frequency signal generator 4, heart yearn 2 top is connected with signal processing unit 5, and heart yearn 2 end is connected with probe 7 by connector 6.Comparatively preferred, signal processing unit 5 is also connected with data remote transmitting module (not shown in figure 1), and the periphery of connector 6 has been laid with the insulation rubber sleeve of insulation protection effect.Its top of pillar 3 seals with housing 1 and is connected, and its end seals with connector 6 and is connected.
In addition, as shown in Figure 1, the side of housing 1 is also provided with the first flange port 8 and the second flange port 9, wherein, the first flange port 8 measures entrance with the well head of oil well surface gathering and transferring pipeline and is connected; Second flange port 9 is connected with the well head backflow mouth of oil well surface gathering and transferring pipeline.
In the illustrated oil field radio frequency bearing analysis device course of work, open the first flange port and the second flange port respectively, well liquid to be detected flows in the medium circulation passage between housing and pillar; Probe then launches the electromagnetic wave of the permanent width of frequency stabilization in measured medium.When electromagnetic wave penetrates measured medium, through electromagnetic intensity can correspondence changes with the difference of liquid water content in well liquid, signal processing unit can determine the number of liquid water content in well liquid by the electromagnetic wave after change detected.
It should be noted that the arithmetic speed for improving signal processing unit, this signal processing unit can be selected and adopt singlechip technology at a high speed and 24Bit high-precision a/d converter.Meanwhile, utilize advanced mathematical model and highly effective algorithm, water cut result of calculation is calibrated, finally draws accurate well liquid water cut.Then, further above-mentioned result of calculation can be sent to server or data center by data remote transmitting module, thus complete the remote monitoring to well liquid.
Need to add is that, as shown in Figure 1, also sample cock 10 can be installed further in the bottom of housing 1.Can sample well liquid by opening this sample cock 10, thus oil field of the present invention radio frequency bearing analysis device is debugged, the PROCESS FOR TREATMENT such as inspection again.
A kind of oil field provided by the invention radio frequency bearing analysis device, a housing is included in this analyzer of water content, enclosure interior is provided with the heart yearn of band pillar, heart yearn is provided with radio-frequency signal generator, heart yearn end is connected with probe by connector, and heart yearn top is connected with signal processing unit.Wherein, between heart yearn pillar and housing, be formed with wellhead liquid medium circulation passage to be detected, the electromagnetic wave attenuation situation of being launched by monitoring probe can complete the analytic process moisture to wellhead liquid.Therefore adopt that oil field its detection speed of radio frequency bearing analysis device of said structure is more quick, accuracy of detection is also higher.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
