Research on Intelligent Extraction of Key Information from Drilling Geological Design Documents

The rapid development of information technology has led to industrial changes and the transformation and upgrading of traditional industries. The oil and gas industry, as a traditional industrial industry, is facing the new situation and trend of accelerating the energy revolution and energy transformation. Under this situation, it vigorously develops the information construction of the oil industry, breaks through the information barriers among various majors in the oil industry, and realizes the information exchange among different majors. It is of great significance to improve the core competitiveness of petroleum enterprises and realize the development strategy of reducing cost and increasing efficiency. In order to realize the information interconnection between the major of oil drilling and the major of geology, this paper adopts the international POSC business analysis model, carries out the demand analysis of the key information extraction business of geological documents, and establishes the business model of key information extraction of geological documents. Through the construction of petroleum engineering information integration platform, the establishment of geological document key information dictionary and the construction of geological document key information extraction template library, the key information extraction method based on natural language processing is optimized. On the basis of the above research, the geological document information extraction module is developed to realize the information fusion between the drilling major and the geological major. After testing 100 geological documents, the key information extraction software developed in this paper shows that the extraction accuracy of key information is 98%, and the average extraction time of a single text is 10s. The extraction efficiency and accuracy are higher than expected, and fully meet the needs of drilling design. This paper provides ideas for the information construction of other majors in the traditional oil industry, breaks the information island between different majors, realizes the inter-professional information exchange, and greatly improves the work efficiency and benefit of the traditional oil industry.
