STRESS SENSITIVITY ANALYSIS OF RESERVOIR ROCK WITH PRIMITIVE EFFECTIVE STRESS
|
Abstract:
Reservoirs are influenced by incumbency rock pressure, sideways pressure and porosity pressure at primitive stratum. This stress state is called primitive effective-stress. After the primitive effective-stress be considered, the law of stress sensitivity still follow the negative exponential attenuation. Compare to no consideration of primitive effective-stress, the descend degree of permeability is more little, so the stress sensitivity is weaker. But the law can suit to the fact, and have practical meanin... \r\n\r\n
