Рассматриваются типичные палеогеоморфологические условия формирования неантиклинальных ловушек нефти и газа в основных продуктивных комплексах нефтегазоносных провинций и областей СССР. Сделан вывод, что изучение пале геоморфологических обстановок, восстановление форм палеорельефа и составление палеогеоморфологических карт являются, важным общим условием направленного поиска не антиклинальных ловушек.
Studies of buried relief and associated loose deposits suggest an essential influence of paleogeomorphological situation on formation of non-anticlinal oi1 and gas traps at different regions of the USSR. The influence has been established for various Phanerozoic epochs of regional continental breaks and was predetermined by relief complexes of different origin and morphology. Non-anticlinal traps are associated with river valleys, inland and submarine deltas, bars, reef constructions and other buried landforms. Such traps are better known from western regions of the USSR (Russian Platform) and are confined to Mesozoic and Paleozoic sedimentary complexes. They also gravitate towards areas of former fluvial-deltaic and coastal (shallow shelf) plains.
