查询词典 seismic activity

Geophysical characteristics of Ordovician carbonate rock were studied using drilling data. Impedance is affected mostly by material properties and reservoirs types, to a negligibly extent by lithology and flow. Compact layers and minor\|fracture reservoirs of Ordovician carbonate rock have characteristics of high density, high velocity and high impedance, and the prediction of minor fractures reservoir is difficult by the general seismic ways. Big fractures and fractured\|vuggy and vuggy and cavity reservoirs of Ordovician carbonate rock have characteristics of minor density and low velocity and low impedance in central Tarim basin, which obviously different from the surrounding rock and produce obvious characteristics in seismic data, so reservoirs can be predicted by applying general seismic data.

根据已钻井资料，对塔中地区上奥陶统良里塔格组岩石地球物理特征进行了研究，结果表明：物性、储层类型对波阻抗影响最大，岩性、流体对波阻抗影响较小；奥陶系碳酸盐岩致密层和小裂缝型储层具有密度大、速度高、波阻抗值大的特点，利用地震常规预测手段较难预测出小裂缝型储层，而塔中地区奥陶系碳酸盐岩大裂缝型、裂缝-孔洞型、孔洞型、洞穴型储层具有密度小、速度低、波阻抗值小的特点，与围岩具有较为明显的差异，在地震上可以产生明显的响应，可利用常规地震资料来预测这种类型储层。

Therefore, local wave decomposition technology was introduced into the logging date extrapolation method constrained by time-phase model to gain the seismic instantaneous phase. The relationship of logging and seismic data was established through the wellside strata correlation. High resolution attributes inversion profiles were generated through the extrapolation of logging constrained by equiphase surface established based on seismic data.

The paper has studyed the characteristics of seismic wave field in the media of EDA, and has made out three aspects of numerical simulation on wave field features by using definite difference: The simulation of P-wave ground seismic logs in the media of EDA; the diagnostic complication of seismic wave field in cranny belts due to the scattering of cranny wrappage; the decreasing of amplitude and the reversing of polarity of the wave reflected on not only the top but also the bottom of fracture zone.

2通过罗67井岩芯的系统研究表明，泥岩的横波和纵波速度随温度增大而降低，一定温度条件下随为压力而增大；泥岩裂缝的测井曲线一般表现为高电阻率、负自然电位异常、低声波时差，利用该规律可以半量定地识别划分泥岩裂缝储层特征，为解决不同度数据的相互匹配这一重点和难点问题提供了思路和方法。

The new method for seismic attribute analysis colligates information of seismic,logs and geology by crossplot and broadcast and cluster with the methodology of science instead of analysis with handcraft and eyeballing.With the method,seismic attribute analysis plays an important role in subtle traps exploration. \r\n

指出新型的地震属性分析方法一改以往的手工、目测分析方法，充分利用了二维、三维及多维交汇方法，为属性分选、分析提供了便利的操作手段；新型的地震属性方法还运用科学分类方法，综合地震、测井、地质信息，把剖面、平面及分类结果结合到一起，通过三维一体的相互信息映射，在储层预测中的目标初选及目标分析中起到了举足轻重的作用，真正做到了属性分析的科学性、实用性。

Besides various interferences, the wave front diffusion, the ground absorption and the attenuation are all the causes of a weak seismic reflection and, plus the complicated superficial geologic setting and the reservoir bed features of low amplitude, low porosity and low permeability of the compacted thin detrital rock in HJQ, the conventional seismic amplitude fidelities do not meet the criteria of the seismic inversion.

除各种干扰外，地震波传播过程中的波前扩散、大地吸收、衰减等使地震反射能量变弱，加之杭锦旗地区复杂的表层地质条件和低幅、低孔、低渗致密性薄层碎屑岩的储层特点，使常规保幅地震资料离地震反演的要求还有差距，并且反演技术本身不具备噪音识别功能，包含噪音的反演必然会影响地质效果。

Two primary seismic facies models (onlap fill seismic facies and mounded seismic facies) are established.

Based on this line of thought, following conclusions are attained: if the seismic design was based on the force method, as long as the power spectra of the model can be close enough to fit the actual average power spectra of the earthquake acceleration records, the model can be used to simulate seismic process; if the seismic degsin was based on the displacement methods, the more stringent constrains should be applied to the power spectra to model.
