Pore-Scale Simulation of Particle Flooding for Enhancing Oil Recovery

چکیده
The particles, water and oil three-phase flow behaviors at the pore scale is significant to clarify dynamic mechanism in particle flooding process. In this work, a newly developed direct numerical simulation techniques, i.e., VOF-FDM-DEM method employed perform of several different processes after flooding, which are carried out with porous structure obtained by CT scanning real rock. study on distribution remaining displacement process viscoelastic particles shows that capillary barrier near location abrupt change radius main reason for formation oil. There threshold producing Only when force exceeds threshold, can be produced. behavior particle–oil–water under three modes, continuous injection, alternate injection slug studied. It found size mode have an important influence fluid flow. On basis, behavior, pressure characteristics recovery efficiency modes compared. injecting two kinds fluids resistance increasing ability into pores, they enter channels, resulting imbalance interface between realize rapid

A Pore Scale Evaluation of Produced Biosurfactants for Ex-situ Enhanced Oil Recovery
Microbial enhanced oil recovery (MEOR) is an economical method used to improve the oil recovery from reservoirs. In the MEOR techniques, by applying different microorganisms, a variety of products such as bioacid, biogas, biosurfactant, and biopolymer are generated, among which biosurfactant, one of the important metabolites, is produced by bacteria. It is worthy to note that bacteria are suita...
متن کاملsimulation 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. ...
RESEARCH ON CO2 FLOODING FOR IMPROVED OIL RECOVERY IN WATER FLOODING ABANDONED RESERVOIRS
CO2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. In this study, the lower part of Es1 reservoirs in Pucheng oilfield was introduced as the target reservoir. By studying the minimum miscible pressure in CO2 flooding, the reservoir could achieve miscible flooding. Long core displacement experiments prove...
