transport through porous media: Design and conduct core flooding
experiments to study surfactants transport through porous media for
foam flooding. Describe core compositions and structure by X-ray
diffraction, SEM, Thin Section, and AFM to analyze solute transport
mechanism through porous media.
of liquid/solid: Design and conduct batch experiments to study
surfactants sorption onto minerals. Conduct Zeta Potential experiments
to understand mechanisms of surfactant adsorption onto minerals.
simulation: Based on laboratory experiment results, model the transport
of surfactants through porous media and optimize foam flooding process
by using numerical simulator.
- Worked on
projects related to conformance control,chemical EOR and reservoir
simulation, funded by CNPC, PetroChina, SINOPEC, CNOOC and
of oilfield chemicals: Synthesized several kinds of gel, such as
in-situ weak gel and strong gel, preformed particle gel, and so on, and
a temporary plugging agent. These gels can be used in the reservoirs
with temperature from 20 to 130 0C and salinity up to 300,000 mg/l and
have been successfully applied to control conformance. The temporary
plugging agent is characterized by temporarily plugging low
permeability zones during gel injection process and automatically
dissolving after gel injection.
of oilfield chemicals: Evaluated the influences of reservoir conditions
on gel, polymer and W/O emulsions, including effects of temperature,
salinity, and reservoir core properties. A series of evaluation methods
of gels were developed and were published as a petroleum industrial
standard of China.
- Fluid flow
in porous media: Designed and conducted core flooding experiments to
evaluate the flow behavior and rheology of polymers, gels, emulsions
and preformed gel
