Description
Technical Field
The invention relates to the technical field of oil-water two-phase flow water holding capacity measurement in petroleum production logging, in particular to an integrally formed water content measuring sensor.
Background
At present, most oil fields in China enter a middle and late development stage, water flooding, gas flooding and polymer flooding become important means for increasing and stabilizing the yield of the oil fields, the complexity of fluid components and forms in crude oil exploitation is improved, and the difficulty in measuring fluid parameters in production logging is increased.
The water injection development is still the most common development mode of oil wells in middle and late stages, most of produced liquid is oil-water two-phase flow, and a small amount of gas is separated out along with the rising of the produced liquid, so that the measurement of the water content of the oil-water two-phase flow has important guiding significance for determining the water or oil outlet layer position, estimating the yield, predicting the development life of the oil well, controlling the yield and quality of the oil field, detecting the state of the oil well, improving the quality of secondary oil recovery and the like.
The conductivity measurement method and the capacitance measurement method are widely applied to the measurement of the water holding capacity of the corresponding sensors due to the advantages of simple measurement theory, simple structure, low cost, reliable performance and the like. The conductivity method sensor mainly calculates the water holding rate based on the difference of the fluid conductivity between the two electrodes, is mainly used for measuring the dynamic water holding rate, has good real-time performance, but has difficult dynamic measurement effect to directly reflect the water content of the whole fluid between the polar plates. The capacitance sensor calculates the water holding capacity mainly based on the difference of dielectric constants of media between two polar plates, and has high sensitivity but poor linearity of sensitivity characteristics between the polar plates.
The construction of the digital oil field becomes the main trend of the current oil field development. The unmanned oil field management is realized by automatically acquiring relevant parameters of a well head, automatically communicating remote information, automatically remotely operating and the like, and the method has great significance for reducing the exploitation cost of the oil field, reducing the labor intensity of workers, improving the quality of the oil field management and the like. The acquisition of wellhead related parameters mainly aims at measuring parameters such as wellhead images, fluid parameters (such as temperature, pressure, flow rate, phase content rate and the like), the height of the working fluid level, the power of the oil pumping unit and the like. At present, the comprehensive measurement aiming at the phase content rate in the fluid parameters is mainly used for comprehensively measuring the fluid parameters of a wellhead or a production area through a metering station or vehicle-mounted comprehensive fluid parameter measuring equipment, and has the advantages of high measurement precision, high cost, poor real-time performance, high labor intensity of workers and incapability of accurately reflecting the change condition of the phase content rate of the fluid in a single well in real time.
In view of the above situation, starting from the actual construction needs of oil fields, on the basis of meeting the measurement accuracy of the water content of the oil-water two-phase flow as much as possible, how to design a capacitance-conductance integrated sensor which can measure the water content of single well equipment and digital oil field construction in all weather and in real time, and has the characteristics of simple structure, low manufacturing cost, low maintenance cost and the like becomes a problem to be solved urgently in the field.
