Introduction:
A
mudlogger in the modern oil field
gathers data and collects samples
during the drilling process. This
information is then organized in the
form of a graphic log. This information
(known as "offset data")
can provide valuable clues as to the
characteristics of the particular
geo-strata that the rig crew is about
to drill through. Mudloggers have
to connect various sensors to the
drilling apparatus and install specialized
equipment before they can monitor
or "log" drill activity.
This can be quite strenuous and challenging,
especially when having to be done
during drilling activity. Much of
the equipment will require precise
calibration or alignment by the mudlogger
to provide accurate readings.

System
Requirements:
Mudloggers
observe and interpret the indicators in
the mud returns during the drilling process.
At regular intervals the mudlogger logs
properties such as drilling rate, mud weight,
flowline temperature, natural gas content
and type, oil indicators, pump pressure,
pump rate, lithology (rock type) of the
drilled cuttings, and various other items
of interest. The job of a mudlogger requires
a good deal of diligence and attention.
Sampling the drilled cuttings must be performed
at predetermined intervals, and can be difficult
during rapid drilling.
Our
customer's specific requirements were as
follows:
- Over
30 data parameters needed to be recorded
and controlled
- The
device should be able to withstand the
harsh conditions of a modern oil field
(intense electromagnetic interference,
noise, vibration, unstable currents)
- Distributed
control on the mudlogging device should
be implemented by advanced computer control
technologies, so as to improve the control
precision of all technological parameters
during the operation

Description:
The
host panel PC on the electrical control
cabinet of the mudlogging unit implements
functions of: 1) Detection processing; 2)
Closed loop controlling; 3) Graphic report
forms; 4) Recording; 5) Online adjustment;
6) Printing; 7) Alarming; 8) Statistical
analysis; 9) Historical documentation; 10)
System safety; 11) Web features; 12) User-friendly
HMI.
The
sensor monitors accidents such as pierced
pipes, lost drills, lost bits, breaks, blowouts
and slough. The monitoring parameters include:
drilling load, pick-up weight, weight on hook,
torque, stack pressure and flow.
Conclusion:
Adding
Advantech's IPPC to this solution provided
the following advantages: touchscreen display;
all-in-one design; robust and durable with
a wide temperature and humidity range, rugged
design that withstands environmental conditions
such as noise, high temperature, dust &
vibration.
Intelligent
control on the modlogging unit could be
now implemented through the IPPC, enhancing
the control accuracy of each parameter,
saving energy, improving efficiency, lessening
maintenance difficulty, strengthening project
monitoring and accurately analyzing oil
& gas status.
