Abstract
The rich oil and gas resources and good reservoir-forming conditions in the Santos Basin in Brazil make it a majorstrategic succession area for oil and gas exploration in the Santos Basin. The sub-salt bio-reservoir-cap configuration in the SantosBasin can be divided into two types: bio-reservoir-cap superposition and bio-reservoir superposition; the preservation conditions canbe divided into cap-slip-off extension deformation type, and the cap-layer is strongly extruded Deformation type, 3 types of capping stable extrusion deformation type; reservoir formation zone can be divided into 2 types: subsalt raw salt storage and subsalt raw salt storage. The high area outside the Santos Basin in the sub-salt source-salt storage zone is a favorable exploration direction for finding large oil and gas areas under the salt in the Santos Basin.
Highlights
The Santos Basin is one of the largest coastal passive marginal basins in Brazil
The TOC content is 2%-4%, and the maximum hydrogen index can reach 500gHC/TOC, Showing lipid-rich algae and bacterial material accompanying the development of stromatolites, kerogen is of type I/II or II/I, and the maturity of source rocks varies greatly
Apte evaporite constitutes the regional caprock of the subsalt sequence in the Santos Basin, and shale and marl constitute the local caprock in the group
Summary
In the Lower Cretaceous Barremian-Lower Apterian stage, the salt lake facies shale source rock of the Guaratiba Group, the reservoir of the Guaratiba Group, and the cap layer of the Ariri Formation form a good vertical generation-reservoir-cap combination in the Santos Basin
