he Polarization of aerosol particles, the induction moment and induction force acting upon the polarized particles and interaction energy between particles in the applied electric field are investigated by means of the dielectric polarization theory.

A new method to study stress sensitivity analysis of tight reservoir and its influence on oilfield development;

Two types of stress sensitivity mechanisms for reservoir rocks:Being favorable for oil recovery;

A theoretical formula of stress sensitivity index with compressibility of rock;

Three-zone composite well test model of condensate gas reservoir in stress-sensitive sandstone;

Pressure transient response in deep-seated geothermal stress-sensitive fissured composite gas reservoir;

Experiment shows that the reservoirs in Yanchang formation of Ordos Basin are stress-sensitive to different extent,resulting in damages of different degree to reservoir oil/water percolation.

Influence of stress sensibility on low permeability gas reservoir in different production methods;

Many researches indicate that stress sensibility appears frequently in low permeability gas reservoir.

Due to produced liquids,reservoir pressure declines,and permeability and productivity of wells decrease correspondingly,which is called stress sensibility.

Influence factor of stress-sensitivity on gas well abandoment pressure and recovery ratio in low permeability reservoirs

Fluid-solid coupling is used to consider the stress-sensitivity in simulation,but it needs a lot data and computing time as the progress of simulation will be impacted.

In this paper, the mechanism of fractured formations stress-sensitivity is deeply discussed in order to offer theory basis for developing this kind of formations with reason.
