The invention discloses an ontology-driven probe type multi-source mass spectrum metadata checking method and system, and relates to the field of mass spectrometers.The method comprises the steps that a pre-constructed mass spectrum domain ontology is loaded, logic metadata fields in the mass spectrum domain ontology are compiled into probe intermediate representation, and the probe intermediate representation is obtained; combining the related probe intermediate representations into a probe family according to instrument models and experimental method types; accessing original mass spectrum data and metadata thereof from a plurality of heterogeneous data sources, executing intermediate representation of each probe in the probe family, and analyzing a plurality of candidate values; and constructing a consistency graph for the plurality of candidate values, carrying out truth value estimation based on the consistency graph to obtain a fusion value and a confidence coefficient, and checking the fusion value according to a semantic constraint rule and unit dimension information derived from the mass spectrum domain ontology. And continuous optimization of probe weight and data source credibility is realized through human-computer interaction and parameter updating, so that a set of mass spectrum metadata intelligent checking solution which can be evolved by itself, can be audited and has high interpretability is formed.

The shallow heavy oil sampling probe selection method and system based on a dynamic mobility window selects data in the process of adjacent well sampling, fits a differential pressure-time function, and then calculates the upper limit and lower limit of the mobility window of each probe to form a probe sliding mobility window, compares each probe sliding mobility window with the best sampling mobility range of the sampling target layer one by one, and selects the optimal probe type. Meanwhile, when the sampling operation cannot meet the success standard, the measured formation pressure and pipeline pressure of the target well are fitted into a new differential pressure-time function to cover the original function, and dynamic adjustment is realized. The beneficial effects of the present application are: improving the sampling success rate, accurately matching the formation conditions and probe parameters through the dynamic mobility window. Shortening the operation time, optimizing the sampling probe type, and effectively improving the operation timeliness. Enhancing system automation, and adapting to changes in complex formations.
