The invention discloses an
optical fiber logging data transmission system based on a TCP / IP protocol and a working method thereof, and belongs to the technical field of
petroleum and
natural gas exploration and development. The
system comprises a control and acquisition module, a power supply module, an auxiliary
signal measurement module and a
photoelectric conversion module which are arranged ona well, a
logging torpedo connector arranged under the well, and a photoelectric
slip ring and a photoelectric composite cable which are used for connecting the well part and the underground part. Anopen type
informatization network
logging platform is constructed by applying high-speed optical cable communication and
Ethernet bus technologies, transmission of logging operation optical signals is achieved, the logging
data transmission rate is increased to 100 Mbps from 1 Mbps, the technical
bottleneck of cable
data transmission is thoroughly solved, a
technical support is provided for research and development of a new generation of array imaging instruments, and the logging data
transmission rate is increased to 100 Mbps from 1 Mbps. The
measurement precision, the information amount, the
image resolution and the logging speed of the instrument are improved, the well occupation time is reduced, the operation risk is reduced, and the production efficiency is improved.
