Fractures in tight reservoirs have always attracted general petroleum geologists’ attentions due to their importance in the processes of hydrocarbon enrichment and oil-gas exploration. Fractures can not only act as main pathways of hydrocarbon migration and fluid flow, but also provide major reservoir spaces for hydrocarbon accumulation. Hence, the distribution and development characteristics of them control the distribution and accumulation of oil-gas in reservoirs, especially in tight reservoirs. Current research achievements on fractures in reservoirs, however, are mainly focus on fracture mechanics (geometry, kinematics, and dynamics), yet chemical processes (geofluid effects and diagenesis) within growing fractures and their influences on fracture attributes are somewhat neglected. Recently, with the improvement and perfection of research techniques and analysis methods, some systematic researches on “fluiddiagenesis” interactions of fractures in reservoirs have drawn a wide attention and the research scope and understanding degree to fractures attributes are deepening gradually (Laubach et al., 2004, 2010; Anders et al., 2014; Fall et al., 2015). Nevertheless, this work has a little been done in China.
