摘要
It is argued that there is a close relationship between zones of regional oil and gas accumulation and major structural elements of the platform cover, which in their turn control the lateral series of sedimentary formations. It is shown that major oil accumulation zones are connected with the axial parts of anteclises, and deposits are concentrated in the Neocomian and Upper Jurassic permeable complexes. Oil and gas-bearing zones are connected with high-amplitude rises within deep syneclises; the main hydrocarbon deposits are found in the Aptian-Senomanian and Neocomian permeable complexes.
