The use of nanoparticles with carbon dioxide foams has been proposed for enhanced oil recovery due to their robust chemical stability in harsh environment. The experimental study was performed by using nanoparticles stabilized carbon dioxide foams to study their recovery of residual oil by varying the carbon dioxide flow rates on different core samples such as sandstone and limestone. Experimental setup was divided into two different kinds of experiments which are the injection of carbon dioxide foams and the injection of nanoparticles assisted carbon dioxide foams in both sandstone and limestone core samples. For the CO2 foam injection, it was found that limestone has higher oil recovery than sandstone rock samples with 38.67% recovery and 36.36% recovery for sandstone. With the nanoparticles assisted injection, the crude oil recovery increased to 41.82% and 45.33% for sandstone and limestone respectively. Limestone showed the higher porosity reduction at the end of experiment compared to sandstone with the porosity of 7.56% on limestone and 12.49% on sandstone respectively. This is due to the nanoparticles strongly absorbed at the limestone surfaces containing calcite component.

In order to study the mechanism of salt-bearing polymer flooding, using micro-flow technology, experimental study of salt-bearing polymer flooding residual oil process was carried outin two microscopic models of hydrophilic and lipophilic formation.Its microscopic percolation mechanism wasinspected. In hydrophilic model, after injecting salt-bearing polymer residual oil is capturedand migrated, and there is residual oil drawinganddeformation phenomena which is consistent with common polymer; while flooding process due to larger viscoelasticity of salt-bearing polymer, normal stress is generated in the flow, so the cutting action of the residual oil is obvious. In lipophilic model, after injecting salt-bearing polymer, residual oil migration, the film gathering,interface transport, a bridge and drawing phenomenon happened which is consistent with common polymer; polymer difference between salt-bearing polymer andcommon polymeris that from the ordinary and the residual oil film formed by common polymer is flexible and easier to form "emulsion.

Flash pyrolysis of cellulose is done on the laser pyrolysis experiment device, from which some water-loving yellow substances are collected, which is confirmed as active cellulose. HPLC analysis shows that the chief constituent of this yellow substances are glucose, fructose and oligosaccharide, and whose yield are determined. The research indicates that: at high-radiation power, glucose is not the only production decomposing from oligosaccharide, and there is another production decomposing from oligosaccharide which will compete against glucose. At last, the mechanism of the first pyrolysis of cellulose is analysed.
