Shale vitrinite reflectivity determination method and device based on neutron-density envelope area, computer equipment and storage medium

The invention discloses a shale vitrinite reflectivity determination method and device based on a neutron-density envelope area, computer equipment and a storage medium, and relates to the technical field of oil and gas exploration and development. According to the method, address characteristics of a research area and a logging response rule are combined, left and right scales of a compensated neutron and lithologic density logging curve of the research area are fixed, unit areas of the compensated neutron and the lithologic density logging curve are calculated firstly, and then envelope areas of the compensated neutron and the lithologic density logging curve are determined; and establishing a relationship between the enveloping area and the vitrinite reflectance of core analysis by adopting a mathematical fitting model, so as to quickly and quantitatively calculate and predict the shale vitrinite reflectance of the well. The operation method is simple, the replicability is high, the calculation progress is high, the calculation result meets the field requirement of an oil field, and the method has good universality and popularization value especially in old well review with deficient data.
