چکیده
Compared with oil, natural gas has been the focus of energy industry in recent years. Renewable is goal and trend future developments, it made considerable progress; however, not reached ideal popularization rate. Therefore, still very important so far. In this paper, influence thermal injection room temperature on reservoir recovery analyzed, method water plugging by hot tight put forward. Indoor simulation experiments were carried out to evaluate effect hot-gas cut pore degree blockage. On basis, numerical removing blockage was out. The changes core remaining saturation discussed using models. Results study can provide a theoretical basis for actual oil reservoirs.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Experimental and Numerical Pore Scale Study of Residual Gas Saturation in Water/Gas Imbibition Phenomena
Residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. Visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. In this study experimental tests in a glass micromod...

According to the temperature distribution of water injection well-bore in highly deviated wells under different conditions and unstable temperature field heat conduction principles, a true three-dimensional model was established to analyze the law of variation on temperature of highly deviated wells during the water injection process, and to analyze the factors that influence the water injectio...
متن کاملAn Experimental Study of CO2-low Salinity Water Alternating Gas Injection in Sandstone Heavy Oil Reservoirs
Several studies have shown that oil recovery significantly increased by low salinity water flooding (LSWF) in sandstones. However, mechanism of oil recovery improvement is still controversial. CO2 that develops buffer in presence of water is expected as a deterrent factor in LSWF efficiency based on mechanism of IFT reduction due to pH uprising. No bright evidence in literature suppo...
