As the overseas oil and gas exploration targets have turned to non-structural type traps with the core of lithology and stratigraphy from the conventional structural traps. Such traps are more complex, and have higher requirements on reservoir prediction technology. Through the combination of sequence stratigraphy and reservoir inversion technique, this paper carried out the lithologic traps recognition of Cretaceous Group strata C in the Campos Basin Block M and identified four effective sands. The results showed that reservoir prediction technique un...
