Abstract:

Three prinicple factors of hydrocarbon chemical prospecting were selected from the data of 30 indices and 124 stations in North Tarim, Xinjiang, with the methods of multivariate statistics (R-cluster analysis and factor analysis). These principle factors are explained as weathering and denudation factor, oil-gas accumutation factor and oil-gas pool boundary factor. Besides, acidolysis hydrocarbon, ΔC, Hg, Rn and Ultraviolet etc. five methods and ten indices were sieved from commonly used chemical prospecting indices for production usage.
