Problems solved by technology
At present, the comprehensive measurement of phase holdup in fluid parameters mainly uses metering stations or vehicle-mounted comprehensive fluid parameter measurement equipment to comprehensively measure fluid parameters at wellheads or production areas. The measurement accuracy is high, the cost is high, the real-time performance is poor, and the labor intensity of workers is high. And it cannot accurately reflect the change of fluid phase holdup in a single well in real time

The invention discloses an integrated forming water-containing rate measurement sensor. One end of the outer side of the inner flow channel of the sensor is provided with a cylindrical pole plate in asurrounding manner, the length of the cylindrical pole plate is smaller than the length of the inner flow channel of the sensor; and a ground ring, a fourth conductance measurement ring, a third conductance measurement ring, a second conductance measurement ring, a first conductance measurement ring and an excitation ring sequentially are arranged at the other end of the outer side of the inner flow channel of the sensor in a surrounding manner, the insulation region is filled with an insulating material, and the sensor is integrally formed. The integrated forming water-containing rate measurement sensor not only is simple in structure, low in manufacturing cost and low in maintenance cost, but also can realize all-weather real-time water content measurement of single well equipment and digital oil field construction.
Description
technical field [0001] The invention relates to the technical field of water holdup measurement of oil-water two-phase flow in oil production logging, in particular to an integrated water cut measurement sensor. Background technique [0002] At present, most oilfields in my country have entered the mid-to-late stage of development. Water flooding, gas flooding, and polymer flooding have become important means of increasing and stabilizing oilfield production. Difficulty in measuring fluid parameters in wells. [0003] Water injection development is still the most commonly used development method for oil wells in the middle and late stage. The produced fluid is mostly oil-water two-phase flow. At the same time, with the rise of the produced fluid, a small amount of gas is precipitated. It has important guiding significance in determining water or oil-producing layers, estimating production and predicting the development life of oil wells, oilfield production and quality contr...
