中国四川东部高陡构造石炭系气田（英文版）

　　This book is a memoir summarizing the exploration experiences of the pasttwenty years in gas field of high steep structures of eastern Sichuan. The analysison five fold-deformation styles of high steep structures gives the vertical variationmodel of the high steep structures.Petroleum generation model，petroleumpotential. reservoir characteri stics. migration and accumulation course，preservation of Carboniferous natural gaspools and pool forming model are systemmatically discussed in this book. Enrichment regularities are put forward Description on case histories are included.Tr0Ublesome questions and how to solvethem are discussed. This book is useful for researchers and explorationists worked in compl icatenatural gas domain. It，is also helpful to teachers and students of university and college.
