Method for predicting exploitation site of unconventional resources applied to sequence stratigraphic analysis

摘要

The present invention provides a method for predicting a shale gas development zone, which comprises: (S1) analyzing a total gamma ray (GR) by depth in a borehole; (S2) Analyzing the spectral gamma ray (SGR) of the U, Th, and K elements in depth; (S3) measuring and predicting the total organic carbon content (TOC) by depth in the drilling core; And (S4) calculating an acoustic impedance (AI) in the borehole.
