Based on the principle of sequence stratigraphy, through analyzing the features of high resolution seis- mic data, a seismic sequence model is proposed to substitute the seismic convolution model, so as to evaluate the reliability of seismic resolution. The seismic sequence model is composed of two parts—the boundary reflection of sequence body and the seismic response of cyclic textures within sequence body. The seismic response of cyclic textures within sequence body is bandpass; they possess different frequency position according to the grade of the sequence body. High resolution seismic data must be able to delineate the configuration of low-grade sequence bodies, and reveal their inner structures. A new processing process to improve the resolution of Seismic data is proposed according to the seismic sequence model. The using of acoustic logging data to compensate the high frequency band needed for the low-grade sequence body is also strengthened. The trial processing results are shown in the paper, which indicate the idea is right, and positive effects have gained in Xinjiang, Shengli as well as Nanhai.

根据层序地层学原理,分析了高分辨率地震资料的特点,并据此提出了一个地震层序模型,以代替地震褶积模型,用以评价地震分辨率的可靠性。地震层序模型由两部分组成:即层序体分界面反射和层序体内部旋回性结构的地震响应。层序体内部旋回性结构的地震响应是带通的,且依层序体的级别不同,分别占有不同的频率位置。高分辨率地震资料应能描绘低级级别层序体外形,并揭示其内部结构。根据地震层序模型,提出了一个新的改善地震资料分辨率的处理流程。强调了声波测井资料在补偿低级别层序体内部结构所需的高频频带中的作用。文中列举了地震资料试处理的结果。试验结果表明地震层序模型和所建议的改善地震资料分辨率的思路是正确的。经在新疆、胜利以及南海等地区应用,实际效果明显。

A new method has been put forward to analyze the dynamic mechanism of continental strata. The method is based on the comparable relationship between the rhythm of strata and the varieties of the paleo-climate or the tectonic episodes, in a simple nonlinear or para-linear geody-namic system. In the research, the technique of sequential frequency process has been used to discern geological periods in stratigraphic sequence, and the volcanic rhythm and the abundance of palaeobiocoenosis have been used to calculate...

A new method has been put forward to analyze the dynamic mechanism of continental strata. The method is based on the comparable relationship between the rhythm of strata and the varieties of the paleo-climate or the tectonic episodes, in a simple nonlinear or para-linear geody-namic system. In the research, the technique of sequential frequency process has been used to discern geological periods in stratigraphic sequence, and the volcanic rhythm and the abundance of palaeobiocoenosis have been used to calculate the values of frequency in the tectonic and paleo-climate field. It is important that some special surfaces, of which the ages are known, are provided in unison when the operations are taken. As a result, it is suggested that there be four major cycles, 32. 2 Ma, 5. 93 Ma, 1. 78~1. 90 Ma and 1. 19 Ma, respectively in the Tertiary of the Liaohe rift. Meanwhile it is noted that tectonic activities are not always major factors forming the continental sequences. For a Ⅲ - 3 order sequence, a correlation between the varieties of tectonic and climatic waves has been found. In a Ⅲ -1 order sequence, the fluctuation of paleo-climate is independent of the changes of tectonic, and the tectonic activities decide the major subsidence periods and their distribution. On the other hand, the palaeoclimate and its varieties have controlled the types of vegetation and the scale of lake basins. So the scale of research objects must been paid enough attention to in discussing the dynamic mechanism of continental strata.

本文尝试将时频分析技术与层序地层学原理相结合,进行陆相层序地层的周期分解,并通过与古气候和古构造的单成因周期对比,探讨不同级序层序地层的动力成因机理。该方法在辽河断陷盆地的应用结果表明,构造和古气候旋回对不同级序陆相层序地层的影响程度不等。小尺度(<1.19 Ma)的古气候和古构造变化具有相关性,两者共同决定层序体发育。Ⅲ级(4.2~8.5 Ma)古构造与古气候变化相对独立,幕式构造活动具有幔源特征,控制主要沉降期和沉降带分布;古气候变化与全球性气候变化相应,决定古植被类型和水体规模,层序结构来自两者的时序配置。古气候变化对陆相层序地层发育仍然具有重要影响。

The texture-sequence analysis was established on the basis of texture-sequence models and time-frequency analysis as well as the quantitative analysis of seismic sections to determine the correspondence between sequence bodies and time-frequency features and that between reservoir properties and time-frequency energy. The targets would be studied in terms of sequence analysis, cycling analysis, reservoir prediction and quantitative description of targets by integrating geological, logging and drilling data. The fundamentals for texture-sequence analysis were to construct effective texture-sequence models and obtain the corresponding seismic responses. The texture-sequence analysis was applied to sandstones/conglomerates on steep slopes, to deltas on gentle slopes, to fans at low ends as well as to other subtle reservoirs in the continental rift-subsidence basins, which had brought out good results.
