河南省中新生代中小盆地的新认识及21世纪油气勘探思路

河南省横跨华北地台和秦岭褶皱带两个大地构造单元,分布着中新生代陆相沉积中小盆地26个,这些盆地分割性强,沉积、构造特征各异,断块发育,具备形成油气藏的基本石油地质条件,有很好的油气前景,21世纪勘探应以寻找断块和与断层有关类型的油气藏为主,在不断引入和运用新科技的同时,走综合勘探、滚动开发的道路。

THE NEW KNOWLEDGE FOR MESOZOIC AND CENOZOIC BASINS IN MEDIUM-SMALL SCALES OF HENAN PROVINCE AND NEW THINKING OF OIL-GAS EXPLORATION IN THE 21ST CENTURY

Henan province has lain across two different geotectonic units of North China platform and Qinling folded belt.In it 26 Mesozoic-Cenozoic continental deposit basins in medium-small type have been distributed.These basins have strong dismembering,the utterly different signature of deposit and structure,fault-block development,and have basic petroleum geological conditions formed oil and gas accumulation and a very good oil-gas prospect.The exploration in the 21st century must take the small fault-block oil and gas accumulation and the accumulation related with fault as the dominant.While importing and using continously new science and technology,we must take the paths of comprehensive survey and rolling development.
