Testing study of methane drainage by bore and hydraulic-cutting seam from low permeability coal seam;

Influence of effective pressure on the physical property in low permeability deformation reservoir;

Research on Non-Darcy flow in low permeability gas reservoirs;

Research on damage test of water injection in low permeability reservoir of Daqing Oilfield;

In block A in Erlian oilfield the interpretation result indicates that some reservoirs with low porosity and low permeability have poor oil & gas reserve,but have high production capability after being fractured.

Considering the characteristics of low porosity and low permeability in the depression, effective evaluation methods for shale volume, porosity, medium diameter of particle, oil saturation and permeability are presented using Artificial Neural Network technique combined with con.

Based on coal seam gas industry that features low permeability in coal reserve bed in China,it is discussed the feasibility of an operational technology,well drilling,will be done by drilling holes parallel to the level of coal bed outside of the bed or projecting holes in multilayer for large slope pits with low polution for coal reserve bed.
