Under construction, please look forward to it
SITAN TLX50-200D
gyroscope inclinometer is an advanced borehole trajectory parameter measurement
system. SITAN TLX series gyroscope inclinometer relies on the inertial
navigation technology of aviation field, using the fiber optic gyroscope and
quartz flexible accelerometer with special impact resistance and vibration
resistance as the core sensor, which is suitable for the harsh working
environment in oil fields, and has high precision and high reliability. SITAN
TLX series gyroscope inclinometer is aimed at various working environments in
oil drilling, with high precision, high speed, and leading technology level in
China.
SITAN TLX50-200D
series gyroscope inclinometer can be used for open hole measurement as well as
cased-hole measurement. It can be used to measure well trajectory, directional
perforation, sidetrack windowing and other construction.
Feature
(1) Aircraft-grade optical fiber gyro sensor, long life time, high-accuracy, fast north seeking.
(2) Automatic north seeking, no need wellhead calibration.
(3) Good shockproof performance, high reliability.
(4) It can be combined with Gamma ray log(GR) and casing collar locator(CCL) for combination logging.
