Abstract: In order to integrate reservoir structure knowledge by using knowledge graph technology and solve the
problem that in the process of ontology modeling，standards are rarely integrated into ontology model，and there
are some problems in the transformation process，such as coarse classification of concept granularity of descriptors
or no classification of descriptors at all，a new method of constructing knowledge graph based on thesaurus is
proposed，which is to mark the original thesaurus，establish mapping rules，construct transformation algorithm
and generate knowledge graph． The algorithm of annotation，mapping rule establishment and transformation
define the standardization process of building knowledge graph． Finally，some knowledge in the field of reservoir
structure is selected to construct the knowledge graph using the proposed method，which shows the feasibility of
the proposed method．
