摘要
现今在以岩性和地层等隐蔽油气藏为主要目标的油气勘探实践中发现储集体的质量主要受构造相、沉积相和成岩相的综合影响,在烃源岩和构造等成藏基本地质条件明确的情况下,寻找受成岩相控制的优质储集体是油气勘探工作的重点和难点。目前国内外关于碎屑岩储层成岩相的研究尚处于探索阶段,在成岩相的分类命名方案、定量表征参数等方面尚未完全达成共识,而且缺乏完善的成岩相的地球物理表征方法。在阅读国内外大量文献的基础上,概述了成岩相概念的提出以及发展历程;归纳了成岩相的控制因素、研究内容、划分依据、分类方法、命名方案和定量评价标准;总结了成岩相在油气勘探各个环节中的应用;最后探讨了现阶段成岩相研究中尚存的问题。在此基础上,就未来成岩相研究的发展方向做出展望,以期能有效推动成岩相研究相关的理论和技术的深入发展。
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 reser- voirs 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 cat- egory 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 pro- gress made by the diagenetic facies research since the 1990s from the following aspects ： ① the concept of diagenet- ic facies and its development progress; ② the content, category basis, classification method, quantitative charac- terization parameters and naming scheme of diagenetic facies ; ③ the application of diagenetic facies to the practice of petroleum exploration and development ; ④The 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.
