Application status and development trend of knowledge graph in petroleum exploration and development
In the energy sector,the efficient exploration and development of petroleum resources based on the knowledge graph(KG)is favorable for promoting the high-quality development of petroleum industry.KG,as an emerging technology based on artificial intelligence and knowledge representation,has become the research hotspot and focus in petroleum exploration and development.In this paper,such current applications of KG are summarized systematically in four major domains,i.e.,geophysical exploration,drilling and completion,well logging,and reservoir engineering.Then,combined with Large Language Models(LLMs),the challenges that KG encounters in the petroleum exploration and development are dissected,and the future directions are predicted.And the following research results are obtained.First,in the field of petroleum exploration and development,KG,combined with deep learning model and expert experience,is widely used in geological data management,information interpretation,anomaly detection and analysis,intelligent decision making support,fault diagnosis,comprehensive analysis of logging data,interpretation of logging data,automatic matching of logging curves,reservoir description,numerical reservoir simulation,reservoir management,and equipment fault maintenance,and achieves the functions such as data quality improvement,data utilization rate improvement,and real-time reservoir performance monitoring,effectively improving the efficiency of exploration and development.Second,when KG is applied in petroleum exploration and development,it face challenges such as multi-source heterogeneous data,acquisition and representation of professional knowledge,knowledge updating and maintenance,demand for computing resources,and interdisciplinary collaboration and application,so it needs continuous research and innovation in terms of technology,standard and collaboration mechanism to fully leverage its potential in petroleum exploration and development.In conclusion,the KG technology with promising prospects is applied to knowledge search,recommendation,sharing,intelligent question-answering,reasoning,and computation,as well as the integration of KG with LLMs in the context of petroleum exploration and development,and the technological research keeps on its focus on large-scale models for petroleum exploration and development,simulation models based on mechanism models and intelligent models,and multimodal technology,etc.,which will propel the industry to be more intelligent,efficient and precise.
