Effect of Temperature and Acidification on Reinjection of Geothermal Water into Sandstone Geothermal Reservoirs: Laboratory Study

Abstract: Geothermal reinjection is a new method of geothermal development which can maintain regional geothermal reservoir pressure, and it is conducive to the sustainable development and utilization of geothermal heat. However, geothermal reinjection blockage has always been a problem that restricts geothermal development and utilization, causing geothermal reservoirs, especially the attenuation of sandstone geothermal reservoirs. Considering an example of a typical sandstone geothermal reservoir in Binzhou, in this s… Show more

“…After the experiments, the core and geothermal fluid samples were tested for principal elements and mineral compositions (Figure 1d), which were used to analyze the water-rock interaction and element migration during the displacement process. The geochemical and mineralogical results from the initial geothermal fluids and cores refer to a separate paper [45].…”

The geochemical and mineralogical results from the initial geothermal fluids and cores refer to a separate paper [45]. The mineralogical composition and major element contents of the ground sandstone specimens was determined by X-ray diffraction (XRD) and X-ray fluorescence spectroscopy (XRF).…”

“…Достаточно широко проблема формирования карбонатных солей в пластовых условиях нефтяных месторождений, моделирование процессов осаждения и пути их решения освещены и зарубежными учеными [13][14][15]. Установлено, что отложение солей в пластах-коллекторах и на нефтепромысловом оборудовании при разработке месторождений Западной Сибири связано с изменением термодинамических условий пластовых флюидов, находящихся в состоянии насыщения по отношению к карбонатам коллектора, нестабильностью закачиваемых вод в пластовых условиях, смешением химически несовместимых вод [9].…”
