Abstract
The core is one of the core strategic resources in the exploration and development of oil and gas fields and plays an im-portant role in the research on facies of oil and gas reservoirs,physical properties of reservoirs,and oil content.Compared with the paper data,the physical geological data of the core has the characteristics of reduction and variability,and the original appearance of the core cannot be preserved for a long time,thus reducing the utilization value of the core.Digital core technologies can collect the original data of the core in time,enrich the geological information of the core,and improve the utilization rate of core data,so it is of great significance to research digital core technologies.According to the production practice of core digitization construction in Shengli Oilfield,the concept,equipment,and technical content of core digitization were described,and many important digital core technologies such as core gamma spectrometry measurement,XRF element testing,magnetic susceptibility testing,and CT scanning were analyzed.The geological application effects of each technology were discussed.The research results show that digital core technologies have the advantages of fast testing,good continuity,large data,and high precision.They can accurately reflect the characteristics of sediment changes and provide an important geological basis for the research on sedimentary genesis,reservoir description and evaluation,material composition,and other issues of shales,carbonate,and glutenite,with a broad application prospect.Digital core data is the continuous data of core scale obtained directly from the core,which is between the original data and the result data in terms of the nature of the data,and it focuses more on the originality of the core,which is the first-hand geo-logical data.Digital core data has unique and important application value and is an important technical means to improve the applica-tion level of the core.关键词
