Detailed description of the invention
Fig. 1 is the schematic diagram of marine oil and gas field subsea pig operating system；
Fig. 2 is the functional block diagram of subsea pig operation real-time monitoring device.
Specific embodiment
As shown in Figure 1 and Figure 2, subsea pig operation real-time monitoring device 22 of the invention is installed on seabed central manifold
11.Oil/gas well output oil gas is pooled to seabed central manifold 11, and through steel jumper pipe 16, pipeline terminal 12 and submarine oil-transportation
Pipeline 13 is transmitted to sea oil storage platform or offshore treatment facility.22 bottom of pipe cleaner operation real-time monitoring device is provided with optical fiber
Interface, and connect fiber grating 21.Fiber grating 21 wraps and is covered in 13 surface of jumper pipe 16 and pipeline under the ocean, is used in combination
Adhesive waterproof tape is coated and fixed.
When pigging operation, the lifting of pipe cleaning emitting cylinder 15 is lauched and is connected to seabed manifold 11 by surface platform, and transmitting is clear
Pipe device 14 starts pigging operation.Pipe cleaner 14 is defeated into seabed after manifold internal duct, jumper pipe 16 and pipeline terminal 12
Oil-piping 13.Vibration is generated when pipe cleaner 14 is run with tube wall, 21 inside fiber core refractive index of the fiber grating hair adhered on tube wall
Changing, so that the wavelength of optical signal of internal reflection be made to change.Since fiber grating reflected light signal wavelength and fibre core are rolled over
It penetrates that rate is linear, then obtains the vibration signal of target fiber position by measuring reflected light signal wavelength variable quantity.
As shown in Fig. 2, pipe cleaner operation real-time monitoring device 22 is internally provided with laser light source 31, the optical signal warp of transmitting
