The organic reef and bank facies, widely developed in Middle Ordovician Yijianfang Formation in Tahe oilfield , are characterized by point reefs and banks within the caronate platforms, and the reservoir spaces are mainly of microfissures and secondary dissolution pores.

The forming mechanism of solutiontype secondary pores is one of the problems which petroleum geologist are very much interested in.

Effectiveness of thermochemical sulfate reduction on oil and gas industry—a H_2S formation accelerating development of the secondary pores in reservoirs;

Distribution and genesis of secondary pores in Tertiary clastic reservoir in Southwestern Qaidam Basin;

Genesis of heterogeneity of secondary pores in deep reservoir of Jiangling Depression;

The secondary porosity type of the clastic rock storage in Ordos Basin;

Relationship between development of salt layers and the secondary porosity of deep reservoirs in Bonan sag;

The controlling factors and processes for the formation of the secondary porosity of the deep-seated reservoir rocks in the Bonan depression,Shandong;
