RESEARCH EXPERIENCE
01/2015-present National Natural Science Foundation of China (No.41402121)
Project: Physical Property Limits for the Gas Accumulation in Upper-Paleozoic Tight Sandstone Reservoirs in the Ordos Basin
Project position: Principle Investigator
Responsibility:
Project leader, analysis the upper and lower petro-physical limits through the pore-throat system of tight reservoir
Calculate and analysis the thickness of irreducible water film as the minimum pore-throat radius
Calculate and analysis the critical pore-throat radius as the upper limit when the capillary force and buoyancy reach a balance in the tight reservoir
fit the linear regression relationship between pore-throat radius and petrophysical parameters, predict the critical petrophysical properties by the critical pore-throat radius values
