Abstract
A Block in Ordos Basin is one of the high-yield exploration and development zones in Changqing
Oilfield in recent years. It is of great practical significance for sustained and stable production to
study forming regularity of Chang 6 reservoir system and optimize favorable area. Based on the
analysis of regional geological background and the guidance of sequence stratigraphy, petroleum
geology, sedimentology theory, the oil and gas enrichment rules and the main control factors of
each small layer were studied and the favorable areas were selected by using logging, core analy-
sis data, etc. Results showed that the main control factors in the study area were source rock
