Tectonic and lithologic reservoirs are developed in the Dainan Formation of MJZ Oilfield

and the understanding of reservoir correlation and development characteristics has multiple solutions. In order to accurately understand the rolling expansion potential of the main layer of the structural lithologic reservoir

it is proposed to establish a regional stratigraphic development model based on the analysis of stratigraphic overlap and thickness characteristics

and through fine reservoir correlation

transform the sand body originally thought to be scattered into the main sand body with continuous scale distribution

and then clarify the rolling potential of the structural lithologic reservoir. The formation of reservoir correlation and description results based on regional stratigraphic development model has positive significance for promoting the rolling expansion of MJZ Oilfield and similar structural lithologic oil and gas reservoirs.
