The present invention provides one kind of system to perform distributive multi-point detection for corrosion, crack, leakage, wax precipitation, scaling and other status in long oil and gas conveying pipeline by means of fiber grating sensing technology. The system includes near-infrared wide-band semiconductor laser source array, wavelength division multiplexer, bi-directional fiber coupler, fiber grating sensor array, spectral analyzer and signal transmission optical cable. The continuous near-infrared light signal the laser source array emits is transmitted to fiber grating sensor array embedded inside the long oil and gas conveying pipeline through the wavelength division multiplexer and the bi-directional fiber coupler, the sensor array detects the varying temperature and pressure of fluid inside the pipeline and reflects to the bi-directional fiber coupler while being coupled to the analyzer and the computer to obtain the conveying status inside the pipeline.
