The invention discloses a site groundwater pollutant automatic tracing method. The method comprises the following steps: A, acquiring the shortest time for a pollutant to flow from a test main hole toeach observing hole along a main flow direction, and the longest time for the pollutant to flow from the test main hole to each observing hole along a lateral direction through a dispersion test in order to calculate a maximum possible distance and a minimum possible distance for the pollutant to flow from a pollution source downstream within two monitoring intervals under different hydraulic gradients; B, building a half space model suitable for a target region, partitioning half spaces Ai and Ai', and determining an effective searching half space; C, locking a pollution source range in thehalf space Ai' of which the attribute flag(A)=0; and D, comparing the monitored pollutant with a feature pollutant within the pollution source range for locking the pollution source. According to themethod disclosed by the invention, overlay analysis is performed on a plurality of half space models taking pollutant monitoring holes and possibly-polluted devices as cores through parameters acquired by the dispersion test, so that the aim of tracing is fulfilled by removing interference items according to eliminative induction.

The invention relates to a method using three-dimensional quantitative fluorescence spectrum derived parameters to judge oil quality and fluid types. The method includes the steps of firstly, using athree-dimensional quantitative fluorescence detector to detect rock samples collected during drilling to obtain original three-dimensional quantitative fluorescence spectrum data; secondly, using theoriginal three-dimensional quantitative fluorescence spectrum data to obtain the three-dimensional quantitative fluorescence spectrum derived parameters; thirdly, according to the three-dimensional quantitative fluorescence spectrum derived parameters and the accumulated three-dimensional quantitative fluorescence spectrum historical data of the oil field, using statistical inductive method to build a diagonal included-angle method chart, an actually-measured oil containing concentration and oil-water change rate interpretation chart and a waterline deviation and standard oil sample deviationinterpretation chart. The method has the advantages that by mining three-dimensional quantitative fluorescence spectrum information, the spectrum feature identification parameters and the interpretation method are formed, and accordingly the judging accuracy of the oil quality and fluid types is increased.
