摘要
The types of reservoir and secondary pores of Lower Cretaceous in Tanzhuang sag were studied on the basis of core observation, thin section analysis, statistics and analysis of core porosity and permeability. The results show that the clastic rocks of Lower Cretaceous in Tanzhuang sag have undergone early and middle diagenetic stages and the present diagenetic stage is at a period of the middle A stage. Primary and secondary pores developed in sandstone, which evolved from primary to secondary pores, pore evolution levels and diagenetic stages have different characteristic in different wells blocks.
