Abstract

The invention discloses an azimuth detection performance calibration device for an azimuth electromagnetic wave resistivity imaging logging instrument. The azimuth detection performance calibration device comprises a calibration device substrate, wherein a plurality of non-coaxial conductive rings and a plurality of coaxial conductive rings are arranged on the calibration device substrate, resistors are connected in series in the non-coaxial conductive rings and the coaxial conductive rings. The device can solve the problem of calibration of the detection performance of the azimuth resistivityand the conventional resistivity of an azimuth electromagnetic wave instrument.

Description

technical field [0001] The invention relates to an azimuth detection performance calibration device, in particular to an azimuth electromagnetic wave resistivity imaging logging tool azimuth detection performance calibration device. Background technique [0002] As oil exploration gradually shifts to the development of thin and complex formations, a large number of wells are drilled with highly deviated wells and horizontal well construction technologies. Geosteering and fine formation evaluation. [0003] At present, for electromagnetic wave resistivity instruments, brine buckets or seawater are often used for detection performance calibration in the ocean. It is difficult to adjust the resistivity value and the cost is huge, and it can only simulate the uniform formation and cannot simulate the anisotropic formation resistivity. For azimuth electromagnetic waves The resistivity detection performance of resistivity in anisotropic formation cannot be calibrated. Contents ...
