An integrated molding moisture content measuring sensor

Abstract

The invention discloses an integrated water content measurement sensor. The cylindrical pole plate is arranged around one end outside the inner flow channel of the sensor, and the length of the cylindrical pole plate is shorter than the length of the inner flow channel of the sensor; The grounding ring, the fourth conductance measurement ring, the third conductance measurement ring, the second conductance measurement ring, the first conductance measurement ring and the excitation ring surround the sensor inner channel in sequence At the other end of the outer side, the insulating area is sealed and filled with insulating material to realize the integrated forming of the sensor. Not only is the structure simple, the manufacturing cost is low and the maintenance cost is low, but it can also realize all-weather real-time water cut measurement for 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...

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
