Neogene gas sandstone reservoirs in Baoshan Basin of Yunnan are characteristic of great various lithologies,high shale content,high porosity,middle-low permeability and electric characters deeply influenced by lithology.

A novel method was proposed and studied for the preparation of porous silica with high porosity using base-dissolving technology.

Using traditional way of powder metallurgy, porous material with high porosity, high penetrability and fine filter precision can be made by mixing additive with powder, then pressing and sintering.

Preparation of porous Al with high porosity by infiltration method;

The porous ceramic filtration materials with high porosity were fabricated by using floating beads as the aggregate and millet/polystyrene pellet and carbon powder as the pore-forming agent.

Diagenetic features and distribution of high-porosity zones in lower Xingouzui Formation of Jiangling depression;

Characteristics of diagenesis saline lake environment and its effect on high-porosity zones;

Advances of research on localized deformation in porous rocks;
