摘要
Huizhou depression is one of the major petroleum contribution areas in Pearl River Mouth basin,and it is significant to the research of abundant hydrocarbon depression with the further confirmation of source rock characteristics and petroleum resources.Comprehensive analysis of the abundance,type,maturity of organic matter,effective thickness,organic carbon recovery factor and production rate,shows that Paleogene Wenchang formation and Enping formation are good source rocks.The quantitative prediction technology of source rock TOC seismic data makes up for the lack of less core and measured sample discontinuous distribution.TOC seismic data predict quantitatively TOC contents and variations in the different depths and different time planes,which has laid a good foundation for the more accurate assessment of source rocks and petroleum resources.Based on the quantitative prediction technology of source rock TOC seismic data and the basic stratigraphy unit of third-order sequence,that,petroleum resources quantities of Paleogene source rocks through the genetic method in Huizhou Depression,are 1.698 times last one.The Paleogene transfer zones which are close to source rocks have the advantage of near-source for hydrocarbons with great exploration potential.
