| 摘 要： | 研究区在新生代为一持续下沉的断陷盆地,碎屑岩十分发育.有些埋藏成岩矿物,其出现深度的温度,等于或接近于其他学者对这些矿物的实测温度.这类成岩矿物包括石英(次生加大)、自生高岭石、自生石榴石、腐蚀状绿帘石及粘土矿物等.根据与温度有关的各种成岩作用,可划分出浅成、中成、深成和超深成四个岩带.业已查明,埋藏成岩带可用以划分和评价碎屑岩储油层.

| Abstract: | The studied area was a downfaulted and depressed basin with continuously subsidence during Cenozoic Era. The clastic rocks were proved to be quite developed and favourable to study their burial diagenesis. It is suggested that the present temperature corresponding to the occurring depth of burial diagenetic minerals in this area is approximate or equal to formation temperature measured by other authors for these minerals, such as overgrowth of quartz, authigenic kaolinite, authigenic garnet, etched epidote and transformations of clay minerals. Based on diagenesis related to temperature, four diagenetic zones can be divided, i.e. shallow, moderate, deep and superdeep zones. It is demonstrated that these zones can be used to classify and assess the clastic reservoir rocks. |
