Technical field
The present invention relates to a kind of photoelectric recognition device of heterogeneous fluid, be mainly used in the energy industry field heterogeneous fluid parameter in the pipeline is surveyed.
Background technology
Heterogeneous flowing is a kind of flow phenomenon of complexity, extensively is present in the energy industry field.For many years, in the petroleum industry field, because the ratio of water is lower in the oil exploitation, polyphasic flow research not causing people's attention.Along with the oil-field development under the severe environmental conditions such as desert, ocean, polar region, and oil exploitation enters middle and advanced stage after the nineties, and most of oil fields take water filling to improve production efficiency, can sneak into water during oil exploitation, thereby form the oil gas water multiphase system.Needed pressure also is subjected to the very big influence of heterogeneous distributions such as oil gas water when using the oil pipeline transfer oil, understands the character that also accurately detects oil gas water multiphase and just seems of crucial importance.Commercial production improves constantly the requirement of aspects such as metering, energy-conservation and control, and the demand of the polyphasic flow parameter being carried out precision real time measuring is also more and more urgent.
Polyphasic flow detects main conductor probe, optical fiber probe or the pressure membrane technology used at present, and in measuring process, these probes will certainly be infected with by oil phase, reduce detection sensitivity; And the Detection Techniques of this insertion type also can cause interference to nowed forming, influence detection accuracy.
Summary of the invention
Purpose of the present invention just provides a kind of photoelectricity recognition methods of heterogeneous fluid, is infected with the reduction detection sensitivity by oil phase with pop one's head in measuring process of existing of the Detection Techniques that solve existing insertion type; And probe can cause interference to nowed forming, influences the problem of detection accuracy.
Technical scheme of the present invention is: comprise photoelectric sensor, A/D converter, microprocessor, storer, display and keyboard, photoelectric sensor is connected with the input end of microprocessor by A/D converter, and storer, display and keyboard are connected with the respective end of described microprocessor.
Described photoelectric sensor comprises a forward direction acquisition sensor and two side direction acquisition sensors, and three sensors are surveyed forward scattering and the lateral scattering of fluid to light respectively.
Compared with prior art, the present invention uses the non-intervention type detection method, disturb little, measure accurately; Use the method for statistics, the various nowed formings that help convection cell carry out Classification and Identification; Use neural network each fluid component flow velocity and flow to be discerned the automaticity height.
