英文摘要 | A detailed study on geochemical processes following hydraulic fracturing can provide important information on the origin of solutes and potential improvement of fracturing technology. However, this remains difficult due to the low resolution of flowback water and high salinity of formation water. To fill this knowledge gap, a shale-gas well was drilled and freshwater was used to fracture the shale. In parallel, laboratory water-rock interaction experiments were conducted. The intensive sampling for flowback water and the use of multiple isotopes provided novel and detailed insights into the water-rock interactions after hydraulic fracturing. The results showed that beyond mixing processes, cation exchange, adsorption/desorption, and barite precipitation were observed both in the laboratory and field studies. Although oxidation of pyrite was observed in most of the laboratory experiments, our findings demonstrate that this process was not evident in field flowback samples that were dominated by mixing of fracturing fluids and formation water. Plain Language Summary The hydraulic fracturing technologies have paved the way toward the development of unconventional shale gas from low-permeability shale reservoirs. The solutes in flowback water after hydraulic fracturing of shale gas reservoirs can originate from injected fracturing fluids and formation water, but may also be derived from solutes liberated by geochemical reactions. However, in most cases, the laboratory data do not match the field data from hydraulically fractured wells. To date, a further refined understanding of geochemical reactions after hydraulic fracturing occurred is critical for tracing the origin of solutes in flowback water (as the main potential pollutants for near-surface environments) and potentially improving the fracturing technology. Except for reported cation exchange and carbonate dissolution, this study showed several new findings, including nitrate adsorption/desorption and limited oxidation of pyrite in field flowback samples that were dominated by mixing of fracturing fluids and formation water, although oxidation of pyrite was observed in most of the laboratory experiments and expected to be comprehensive during field flowback after hydraulic fracturing. Therefore, the potential creation of matrix porosity induced by water-rock interactions of oxidation of pyrite and further induced dissolution of minerals may be limited. |
