DESCRIPTIONTOOL ADVANTAGESTECHNICAL SPECIFICATIONS
It measures
three-axis accelerated velocity, three-axis angular, temperature etc.,
acquiring the parameters such as well deviation, azimuth, tool face etc. via
the DSP calculation, There are two kinds, flexible gyroscope and fiber-optic
gyroscope.
Not interfered by outside magnetic field
Acquire orientation with high accuracy when
the deviation is 0°
Determine real geographic north instead of
magnetic north
Continuous measurement, displaying well
deviation, azimuth, tool face in real time
Flexible gyroscope
Used
both for slim open hole and cased hole, to measure deviation, azimuth of well,
relative bearing and theangle of number one sensor to high side well .
Used
for azimuth measurement of cased hole window opening well
Used
for casing orient positioning perforating of the well.
Checking
the cement bonding quality of different orientation combined with SBT tool.
Solving the orientation problems comes from the
drilling engineering and the production engineering combined with other tools.
Fiber-optic gyroscope
Applied both for open hole and cased hole, to
measure deviation, azimuth of well, relative bearing and the angle of number 1
sensor to high side well.
High
accuracy and better stability will be provided.
Solving
the problems comes from the drilling engineering and the production engineering
while combining with other tools.
