Examples
- A seismic trace calculated from well-log data is called a synthetic seismogram .
由测井资料计算出来的地震记录道称为合成地震记录。 - The principal deficit in making synthetic seismograms is that the input data commonly are incomplete .
制作合成地震记录主要的不足之处是输入资料不全。 - In the area of interpretation , it is important to fully understand the characters of kinematics and dynamics for various wavefields for cross - well seismic data and to perform fine resolution calibration on cross - well seismic sections as well as complete synthetic logs in depth domain . then , we have defined the geological meanings to each reflection sets and a preliminary interpretation method has been set up
在资料解释方面，充分认识井间地震各种波场的运动学和动力学特征，对井间地震剖面的分辨率进行了精细的标定，完成了深度域的合成地震记录，对各个波组特征的物理意义赋予一定的地质意义，初步形成了一套井间地震解释方法。 - Thus many data of deflecting wells can be used for seismic inversion and the problem of multiple solutions can be solved to some degree . this technology comes up to advanced domestic standards . because the water base used to make up drilling mud comes from seawater , researches are made into the effects on resistivity of saltwater mud invasion and the values - selecting methods in reserves calculation are broken through , which continues to use terrestrial oilfields " parameters
针对胜利海上埋岛油田丛式开发井组5 / 6井为斜井这种实际情况，对斜井声波测井资料进行了环境校正，经过反复的攻关研究，通过合成地震记录求准速度，实现了斜井资料的地震标定，解决了建立初始波阻抗模型的技术难题，使大量的斜井资料参与反演工作，减少了地质模型的多解性，提高了储层预测的精度，该项技术达到了国内领先水平。 - Because the synthetic seismic record and the seismic record data got in the surface are not well matching caused by the dispersion of seismic wave , frequent correction between them must be done before use . under control of well logging data , there are two important methods to get wave impedance from seismic data inversion : wave impedance inversion method based on convolution model and wave impedance inversion method based on wave equation . using seismic data attributes can predict the information of logs
测井资料和地震资料是地震勘探中两种最重要的资料，由于地震波的频散，使合成地震记录与地面地震记录不能完全匹配，因此使用之前必须对二者进行频率校正地震资料在测井资料约束下可以进行反演，以求取地下波阻抗，主要有两种方法：基于褶积模型的波阻抗反演方法和基于波动方程的波阻抗反演方法可以用多属性变换由地震资料预测测井信息。
