Description
Technical field: the utility model relates to a kind of improvement of hydroextractor water-oil interface indicator structure.
Background technology: at present, the oil field is in the processing procedure to extraction liquid, and free water knockout (FWKO) and electrical dehydrator are to being a vital link separating of profit.For cooperating production and decision-making foundation, the indicating instrument of employing being provided is two interfaces liquid level gauges, i.e. oil gas interface and water-oil interface indicator.But in actual production, there are not absolute significantly water-oil interface, but there is a profit mixolimnion that thickness is indefinite, the water-oil interface of two interfaces instrument indication, it is the middle part of this mixolimnion, can't indicate last interface and the following interface and the thickness thereof of this mixolimnion, if demulsification is bad, prolong in the thickening always of profit mixolimnion to the dehydration electrode, will cause hydroextractor to stop production, this phenomenon often runs into aborning, and this interface indicator can't be reported to the police in advance, produces to the oil field and brings very big difficulty, the normal operation that influence is produced.
The utility model content: the purpose of this utility model provides the moisture altitude indicator of a kind of hydroextractor, and it has simple in structure, easy to use, measures accurately, reports to the police in time the characteristics that cost is low.The utility model comprises upper cover 1, external electrode 2, interior electrode 3, insulating sleeve 4, low head 5, cable 6, data analysis processor 12; Fixedly connected with upper cover 1 in the upper end of external electrode 2, fixedly connected with low head 5 in the lower end of external electrode 2, axially have fluid-through port 7 on the annular wall of external electrode 2, insulating sleeve 4 is fixed between the upper cover 1 and low head 5 in the external electrode 2, form annular space 11 between external electrode 2 and the insulating sleeve 4, electrode 3 is distributed in the insulating sleeve 4 from top to bottom in several, and external electrode 2, interior electrode 3 are connected with data analysis processor 12 by cable 6.Electrode 3 and external electrode 2 are concentric structures in of the present utility model, and medium is filled in the annular space of whole internal and external electrode, and external electrode 2 is a public pole, and interior electrode 3 such as is at the sets of segment electrodes of physical arrangement.The electric capacity that detects each segment electrode is to detect with same circuit timesharing, if what distribute between the internal and external electrode is that the detection data that each segment electrode collected should be consistent with a kind of medium.If what distribute between each segment electrode is the different oil water mixture of crude oil, water and water percentage, the electric capacity of the different segment electrodes that collect also can have nothing in common with each other.By data analysis, just can judge the distribution height position at interface to segment electrode.After the demarcation of the corresponding relation chamber of experimentizing of water percentage and detected value, can provide definite data for production process.Following table is the quantitative data table of comparisons under the different water cut condition:
| Water percentage | 100％ | 74％ | 60％ | 50％ | 0.09％ |
| Detected value | 2956 | 2650 | 2285 | 1285 | 556 |
The utlity model has simple in structurely, easy to use, measurement data is accurate, reports to the police in time, and cost is low, helps the safety of hydroextractor, guarantees to produce the advantage of normal operation.
