Identifying Lithology and Matrix for Unconventional Reservoir Based on Geochemical Elements Logs

With the importance of unconventional oil and gas resources become increasingly apparent that these unconventional reservoirs identified as challenges facing the industry, this paper proposes a new application of geochemical elements with combining other logging to identify the matrix of unconventional reservoir. Verified by the actual log processing and interpretation of geochemical elements in the complex composition, methods for litho logy identification of limestone reservoir logging, tight sandstone gas reservoirs and igneous reservoir has an obvious advantage.
