| 摘 要： | 近30年时间,层序地层学理论得到了飞速发展,并在石油、煤矿等矿产领域获得了应用,取得了极大的经济效益。层序地层学理论自身不断完善的同时,其突出问题也日益暴露出来:流派众多,多家层序地层学流派对层序的级次、划分方案乃至层序的界线理解各异;不同流派层序地层学者对同一问题看法分歧较大,缺乏广适性;不易制定操作规范;各流派相互融合贯通研究较少。在复杂陆相地层研究中,这些问题尤为突出,并且日益暴露出单一层序地层学流派的不足。由此,决定探讨一种方法思路,力求吸取各家之长,总结出一套陆相地层层序地层学研究方法。分析认为,经典层序地层学和高分辨率层序地层学理论在研究的深度及系统性上、应用的广泛性上比较突出。对两种层序地层学理论基础、层序级次、层序界面等特征分析表明,这两种层序地层学理论上具有相互结合的可能性。为此,以冀东高尚堡深层Es32 3油藏为例,采用经典与高分辨率层序地层学理论相结合的方法,从层序的宏观特征和微观特征出发,建立了工区精细等时层序地层格架。构造格局与沉积特征、生产实践均表明,该地层格架较为合理。理论研究与实践分析表明,在陆相地层研究中,将经典层序地层学与高分辨率层序地层学理论相结合,是提高理论研究的科学性与实际应用效率的有意义的方法。 |

| Abstract: | In the recent 30 years,the theory of sequence stratigraphy,which has been applied widely in the fields of petroleum,coal,and mineral resources,develops greatly.As the theory of sequence stratigraphy makes more and more development,its limitation is being exposed:the multi-genres have different view on the sequence order,division and even the definition.Every genre has a special advantage on some problems,however they could not solve others.The uniform manipulation criterion is not easily made.The study of the amalgamation among different genres is still little.In the lacustrine formation investigation,these problems are especially serious.More and more research shows that any single sequence stratigraphy genre cannot meet the need of investigation completely.Therefore a new methodology on how to syncretize the multi-genre sequence stratigraphy is discussed in this paper.The study shows that the classic sequence stratigraphy and the high-resolution sequence stratigraphy have more advantages on the investigation deepness,systematic methods and the application scopes than others.The characters of the two sequence stratigraphy on theoretical basis,sequence order and sequence boundary also shows that there has great possibility theoretically on their syncretization.An example is taken from reservoir Es32 3 of the Gaoshangpu oil field in eastern Hebei Province to set up the isochronous formation framework on the basis of the macroscopic and microscopic characteristics.Structure patterns,sedimentary features and production reveal that the formation framework is reasonable.In a word,it is very significant theoretically and practically to amalgamate the classic and high-resolution sequence stratigraphy organically to the lacustrine formation investigation. |
| Keywords: | formation framework classic sequence stratigraphy high resolution sequence stratigraphy amalgamation |
