Applied Research On Water-Analysis In Hailaer Area

The hailaer basin oilreservoir type is diversiform, tectonic conditions complex. The region the different sections of the different horizon underground gas and water properties may be different, but the distribution law has its special characteristic。The hailaer basin groundwater samples is selected as a researching aim。Adopting clustering analysis to analyze its different sections of the inorganic ions composition characteristics, use of cluster analysis to the different sections of the position, thickness water samples parameter establishment clustering analysis dendritic diagram, taking the similarity coefficient for clustering statistic, according to the different characteristics of formation water samples affinity-disaffinity relationship classification, differentiate and determine the effluent water formation with watery stratum characteristics。Fisher discriminant analysis and applied respectively established Bayes discriminatory analysis of different characteristics in water sample, use discriminant functions are calculated the discriminant indices for unknown watery and classification and its classification criterion.This thesis research achievements, can of stratigraphic attributes do relatively accurate, quantitative judgment, rapid intuitive get underground reservoirs of the important information, is a powerful of exploration logging conclusion supplement and validation, to further development decision support, provide data for oil well formulated the development plan of importance.
