Nowadays, most of the continental oil fields in China have stepped into the petroleum exploration stage, and the main exploration targets aim at the subtle reservoirs such as lithologic and stratigraphic reservoirs. In the practice of the petroleum exploration and development, scholars and experts gradually realize that the reservoir property is the consequence of the combined effects of tectonic facies, sedimentary facies and diagenetic facies. As a result, the research of diagenetic facies occupies an important position in reservoir evaluation and prediction under some specifical background of tectonic and sedimentary facies. In other words, if the basic geological conditions for reservoir formatting such as source rock, tectonic and sedimentary characteristics are already clear and definite, then the crucial points for petroleum exploration are how to figure out the distribution zones of the high-quality reservoirs which are mainly controlled by diagenetic facies. But up to now, the related research of diagenetic facies in clastic reservoir at home and abroad is still at the exploratory stage, and there is very little consensus about the category basis, naming scheme and quantitative characterization parameters and so on. Even more unfortunately, there are no perfect technology and theory systems on the study of logging and seismic response characteristics of various diagenetic facies. On the basis of literatures study both at home and abroad, this article mainly talks about the progress made by the diagenetic facies research since the 1990s from the following aspects: ① the concept of diagenetic facies and its development progress; ② the content, category basis, classification method, quantitative characterization parameters and naming scheme of diagenetic facies; ③ the application of diagenetic facies to the practice of petroleum exploration and development; ④ The present problems and the future trends of this research technique were also discussed for the deep development of relative theory and technology of diagenetic facies effectively. From what has been discussed above, the author then puts forward the future development direction of diagenetic facies and hopes to promote the deep development of relative theory and technology of diagenetic facies effectively.
