The invention provides a method and device and equipment for predicting the total organic carbon content, and a storage medium. The method comprises the steps that logging parameters of a to-be-predicted area are obtained; the logging parameters are input into a preset prediction model, the total organic carbon content of the to-be-predicted area is obtained, the preset prediction model is obtained through training of multiple logging parameter samples and total organic carbon content samples corresponding to the multiple logging parameter samples, and the preset prediction model is established through a model kernel function; the model kernel function is determined according to the Pearson coefficients of the plurality of logging parameter samples and the total organic carbon content samples corresponding to the plurality of logging parameter samples; according to the total organic carbon content of the to-be-predicted area, the oil and gas resource abundance of the to-be-predicted area is analyzed, the prediction cost and the oil and gas exploration cost are reduced, the prediction result of the total organic carbon content is more accurate, and the prediction precision of the total organic carbon content of the lacustrine facies shale is improved.
Description
technical field [0001] The invention relates to the field of petroleum technology, in particular to a method, device, equipment and storage medium for predicting total organic carbon content. Background technique [0002] Total organic carbon (Total Organic Carbon, TOC) content is one of the main indicators to evaluate the hydrocarbon generation ability of source rocks, and its size is directly related to the identification of oil and gas sources and the calculation of resource potential in the study area. An important parameter for resource evaluation. [0003] In related technologies, there are mainly the following methods for calculating the TOC content: △logR method, improved △logR method, multiple regression method and MLP neural network method, etc. After obtaining the logging data, the logging data is brought into Existing formula to calculate TOC. [0004] However, the existing technology is difficult to accurately predict the total organic carbon content, the accu...
