چکیده

Production of sand in sandstone reservoirs is considered a fundamental issue in some oil and gas fields due to the damages and economic problems it brings. Sand production leads to the occurrence of numerous problems, including erosion of oil exploitation equipment, environmental damage, reduction and interruption in production, and sometimes loss of the well. Therefore, it is very important to control sand production from sand producing wells. So far, various methods, including mechanical and chemical, have been presented and carried out to control sand production, and in chemical methods, the sand formation is consolidated through the injection of polymer fluid, such as various resins, polymer gels, etc. In the background of the research, action and tests carried out in the use of different types of resins to consolidate sandstone reservoirs, the obtained results have shown the success of resin injection. In this study, modified nano silica surface was used for chemical consolidation along with melamine formaldehyde aqueous base resin synthesized in the laboratory. The results of Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Test (TGA), compressive strength and permeability tests show the success of surface modification of silica nanoparticles and the efficiency of the synthesized nanocomposite as a chemical consolidation fluid.
