Abstract
The invention provides an oil-water proportion sensor used for a petroleum producing well. The oil-water proportion sensor comprises a cylindrical plastic pipe and a plurality of oil-water proportion sensor electrode groups. The oil-water proportion sensor is characterized in that the oil-water proportion sensor electrode groups are uniformly distributed at the outer side of the pipe wall along the circumference of the pipe wall, AC high frequency electromagnetic waves of different frequencies are applied between a first oil-water proportion sensor and other oil-water proportion sensors so as to obtain different dielectric loss values S1 to Sn, dielectric oil content is corresponding to high frequency loss, the corresponding relationship between dielectric oil content and high frequency loss at the time is determined, so the percentage content of oil in a dielectric can be calculated and the percentage content of water in the dielectric can be calculated accordingly. Correction is carried out according to related temperature, processing is carried out by using corresponding monitoring software, so accurate percentage contents of oil and water can be obtained. The oil-water proportion sensor can be directly mounted on an oil-conveying pipe and can be used for monitoring the mixing proportion of oil and water in a mixed liquor output from the petroleum producing well.
Description
Technical field
The invention belongs to energy field, be specially adapted to the metering of content of material in oil field, field of food, field of Environment Protection.
Technical background
In China's oil-field development, need oil-water ratio in metering oil, traditional metering method is that well product is sent in multiphase separator, by separation vessel by each phase separately, respectively organize by being arranged on separation vessel the output that the flowmeter on phase discharge pipe measures various fluids again, its system weight and volume are all larger, have all increased great difficulty to design and construction.
Summary of the invention
The present invention is in order to solve in oil-field development, can continuous measurement in to the unseparated situation of profit, thus traditional measuring apparatus by measuring separation vessel and backup system and form, the technological process of simplification Petroleum Production can be replaced, dwindle usage space, alleviate testing apparatus weight.
The scheme that the present invention solves its technical matters employing is a kind of oil-water ratio sensor for Petroleum Production well, comprise cylindrical plastic pipe, many group oil-water ratio sensor electrode groups, every group comprises again multiple oil-water ratio sensor electrodes, it is characterized in that cylindrical plastic pipe can be in the work of steady and continuous under high temperature and high pressure environment, oil-water ratio sensor electrode group is to be evenly distributed on tube wall outside along tube wall girth, and the adquisitiones of oil-water ratio value is to be as the criterion with the 1st group of oil-water ratio sensor electrode group, between the 1st oil-water ratio sensor and other oil-water ratio sensors, add respectively the frequency electromagnetic waves that exchanges of different frequency, just can obtain different dielectric loss value S
1～Sn, they are all wave frequency functions, wherein a certain frequency range is only high to the oil content susceptibility in medium, be called oil mass window, under this oil mass window, oleaginousness and the high-frequency loss of medium have corresponding relation, measure the now corresponding relation of the two, bring in relevant mathematical model as independent variable, can obtain the degree of oil in medium now, can correspondingly obtain the degree of the water yield.What more than calculate employing is single-chip microcomputer scale-of-two progression computing method, calculated amount is larger, also need to revise according to relevant temperature, carry out again after modulation /demodulation transmitting and mouthful transferring data to computing machine by single-chip microcomputer, after processing by corresponding monitoring of software, could obtain more exactly profit percentage composition.
The present invention can be directly installed on petroleum pipeline, dwindles usage space, alleviates the weight of testing apparatus, oil water mixing proportional that can Real-Time Monitoring producing well liquid outlet quantity.
The present invention can be directly installed on pipe laying, adopt advanced measuring technique, can be to testing medium continuous measurement in unseparated situation, and can replace traditional measuring apparatus being formed by measurement separation vessel and backup system, simplify Petroleum Production technological process, dwindle usage space, alleviate testing apparatus weight.And in actual well operations, can provide the valuable information such as relevant which kind of fluid of oil well piece regional production, can improve like this oil well management and make sooner, more accurate oil well production determines.
