Abstract
(EN)

A system for determining properties of a tubing string in a subterranean formation includes a measurement device that obtains a plurality of measurements of the tubing string at a particular location. The plurality of measurements correspond to either a plurality of transmitter signal frequencies or a plurality of measurement time slots measured by at least one receiver, and a thickness and a diameter of the tubing string at the particular location is known. The system further includes a processor that determines a plurality of calibration coefficients based on the plurality of measurements, the known thickness, and the known diameter by: assigning calibration coefficients of an equal magnitude to measurements corresponding to at least two frequencies of the plurality of transmitter signal frequencies; or assigning calibration coefficients of an equal value to measurements corresponding to at least two slots of the plurality of measurement time slots.

Suatu sistem untuk menentukan sifat-sifat untaian pipa-tabung dalam formasi bawah tanah termasuk peranti pengukuran yang memperoleh sejumlah pengukuran untaian pipa-tabung di lokasi tertentu. Sejumlah pengukuran sesuai dengan sejumlah frekuensi sinyal pemancar atau sejumlah slot waktu pengukuran yang diukur oleh setidaknya satu penerima, dan ketebalan dan diameter untaian pipa-tabung di lokasi tertentu diketahui. Sistem selanjutnya mencakup prosesor yang menentukan sejumlah koefisien kalibrasi berdasarkan pada sejumlah pengukuran, ketebalan yang diketahui, dan diameter yang diketahui dengan: menetapkan koefisien kalibrasi dari besaran yang sama untuk pengukuran yang sesuai dengan setidaknya dua frekuensi sejumlah pemancar frekuensi sinyal; atau menetapkan koefisien kalibrasi dari nilai yang sama untuk pengukuran yang terkait dengan setidaknya dua slot dari sejumlah slot waktu pengukuran.
