DESCRIPTIONCONFIGRATIONTECHNICAL SPECIFICATIONSADVANTAGES
Segment
cement bond logging tool is applied to measure the quality of cement bonding around
a cased hole both in vertical and horizontal directions, showing the cement
bonding quality at casing-to-cement interface(the first interface) in a grey
level plot, and evaluating the cement bonding quality at cement to formation
interface(the second interface).
Connected
with Gyroscope
Monopole core cable
Max. Operating temp.:
175℃
Max. Pressure: 140Mpa
Casing size: 114.3mm~244.5mm(recommended
size:114.3mm~190.5mm)
Resolution: 6points/ft(at
550m/h)
Accuracy:±5%
Logging Speed: Max. 550m/h
Tool diameter: 70mm、89mm、51mm
The
tool consists of a cartridge and a sonde,
the cartridge is connected to the top of the sonde through a pressure-bearing
connector.
The
transducer array composited of short spaced, 8 transmitters 8 receivers or 1
transmitter 8 receivers transducers, is used to measure the acoustic amplitude
for total eightsegments of 45°each
around the cased hole, providing a standard 3’sonic amplitude and a
5’full wave measurement.
Wear
resistant bellows of small size are applied in design, that havebetter sound insulation, and wide applications.
With
well temperature sensor on sonde, well temperature parameters will be provided
simultaneously.
Displayed
in grey-scale plot, cement bonding status at casing-to-cement interface( the
first interface) will be shown obviously, to estimate correctly the channeling,
the size, position and distribution of the
cement for the first interface, and also can to estimate the cement bond status
for the second interface(.cement to formation interface)
The
height of the cement filled can be exactly evaluated.
Be
suitable for the evaluation of the cement bonding quality for the new and old
wells.
Integrated
design with the high resolution sonic tool.
Exact
positioning the accurate orientation of channeling and hole based on the
geological north when connected with Gyroscope tool.
Compare with normal
sonic VDL tool:
FJCY includes all
logging information of sonic VDL tool, and can replace VDL tool while logging.
FJCY can monitor and
evaluate the first interface cement bond quality of the well around and can display
directly the hole position, size and distribution of the first interface.
It can identify the
more interpretations of measurements, caused by the pressure in well or other
reasons lead to micro channels, or/and partly cement bonding.
