The invention discloses a measuring probe and assembly and a method and device for measuring oil phase volume flow and oil holdup, and relates to the technical field of dynamic monitoring of oil fieldproduction wells, wherein the measuring probe is applied to low flow measurement and comprises a conductive probe assembly, wherein the conductive probe assembly is provided with a probe bottom plate, a conductive probe assembly cavity is arranged on the inner side of the probe bottom plate, a wire passage is arranged in the conductive probe assembly cavity, any side of the probe bottom plate isfixedly connected with a conductive probe through a conductive probe fixing mechanism, and the output end of the conductive probe is communicated with the wire passage; and a plurality of oil bubblesand water pass through the conductive probe, the conductive probe respectively measure the duration time of the plurality of oil bubbles and the water. The invention aims at solving the problems of difficult measurement, low accuracy and more influencing factors of the water content of an oil well with a daily liquid yield less than 10m<3> / d and a water content more than 50% in the later development period of domestic oil fields.
Description
technical field [0001] The invention relates to the technical field of dynamic monitoring of oil field production wells, in particular to a measuring method and device for measuring assembly, oil phase volume flow and oil holdup. Especially suitable for daily liquid production less than 10m 3 / d. Oil wells with water cut greater than 50%. Background technique [0002] The daily liquid production rate is less than 10m in the late stage of domestic oilfield development 3 / d. For oil wells with a water cut greater than 50%, it is difficult to measure the water cut, the accuracy is low, and there are many influencing factors. Contents of the invention [0003] In view of this, the present invention provides a measurement method and device for measuring assembly, oil phase volume flow and oil holdup to solve the problem that the daily liquid production is less than 10m 3 / d. The water cut of oil wells with water cut greater than 50% is difficult to measure, the accuracy is l...
