Abstract:

Buried hill of Mesozoic volcanic rocks are of excellent reservoir forming conditions,but exploration degree was
not adequate which was confined by study of reservoir. Focusing on factors which affect reservoir development,combined
analysis of geophysics and petroleum geology materials,we began with lithology,lithofacies and types of reservoir spaces,
and concluded that acid lava reservoir was better developed while reservoir of basic lava and tuff was closely related with
the intensity of secondary transformation on the same condition. Furthermore,lithology,lithofacies and structural movements
controlled the devolvement of reservoirs. Based on the results of the above analysis,combined with the lithology and exploration
stage of Mesozoic volcanic in study area,favorable exploration targets could be determined with analysis focused on recognition
of characteristic lithology and lithofacies in single well,and analysis on intensity of regional structural moments.

Key words: Bohai Sea Area, Mesozoic volcanic rocks, reservoir development, lithology and lithofacies, structural movement
