Embodiment
[0125] Now the embodiment of the present invention will be specifically described through the following examples and comparative examples, so as to further reveal the technical effect that the present invention can achieve.
[0126] In this example, the evaluation method of the organic carbon content of mud shale includes figure 1 Steps S101 to S108 are shown. Specifically, firstly, the logging data of Well A of Eagle Ford are obtained. The logging curve of this embodiment is as figure 2 shown, according to figure 2 According to the mud shale identification method described above, the mud shale layer is located in the formation through lithology identification.
[0127] After determining the mud shale layer to be processed, this embodiment utilizes the correlation between the combination of lithology density and acoustic wave time difference in the tuff interval, the organic matter damage interval, the organic matter normal preservation interval and the lithological compl...
