Pore characteristics and origin of reservoirs in the southern Tamtsag Sag
Online published: 2012-02-20
The southern Tamtsag Sag is located in the southernmost central rift of Hailaer-Tamtsag Sag. The main oilbearing layers are Tongbomiao and Nantun Formation（he first and second member of Nantun Formation）. The core data combined with thin section, casting thin section and scanning electronic microscope were applied to study the rock types and pore characteristics of Nantun and Tongbomiao Formation. The result shows that the reservoir of Tongbomiao Formation is mainly of tuffaceous sandstone, the reservoir of the first member of Nantun Formation is mainly of ordinary sandstone, the reservoir of the second member of Nantun Formation is mainly of sandstone, and these reservoirs all developed secondary pores. It is also considered that the reservoirs in the study area are mainly controlled by rock types,
albitization and clastic particles shell.
