[Abstract]:The small diameter electromagnetic correlation flow measurement sensor has a wide application prospect in the field of oil production logging, among which, The parameter design of the excitation coil is one of the key technical problems in realizing the sensor. By analyzing the theory of measuring the space magnetic field inside the sensor and the measuring principle of the sensor, a new magnetic field evaluation index is put forward, and at different velocity of flow, In the case of different axial length of excitation coil, the new magnetic field evaluation index is compared with the traditional magnetic field evaluation index, and the design parameters of the axial length of the excitation coil of the flux measurement sensor by electromagnetic correlation method are obtained by using the new magnetic field evaluation index and the traditional magnetic field evaluation index. The experimental platform is built for the preliminary experimental verification, which provides a scheme for the optimal design of the excitation coil of this kind of sensor, and speeds up the development process of this kind of measuring instrument.
