The storage space is dominatecd by the solution micropores, the honeycomb-like solution pores and the kaolinitic intercrystalline pores with small to very small pore throat.

The storage spaces of the carbonate rocks resulted from the interaction of multistage dissolution and infilling,which may be divided into four stages on the basis of the development and evolution.

In-depth analysis is made on lithology,storage space type,porosity evolution,pore-fissure combination of volcanic rocks and their influencing factors in northwestern margin of Junggar basin.

Diagenetic reservoir facies and reservoir space evolution of the Quantou Formation of Lower Cretaceous in Xinli Oilfield,Jilin Province;

Analysis on origin of the secondary dolomite reservoir space of Yeli - Liangjiashan formation in Jiyang Depression;

Genetic models on carbonate reservoir space of buried hill type.;

Analysis on the design of bottom overhead space of college architecture;

The results think that fracture and secondary pore space are chief reservoir space types in region of interest.

This research mainly covers the property core observation,the casting thin sections observation and identification and the analysis of sedimentary facies,reservoir space types,reservoir physical types by characteristic of lithologic,geophysics and organic sediment about Ordovician Yijianfang Formation in the Tuofutai area of Tahe(River Tarim) oilfield.
