波列图系反射地震记录的特殊展示,从反射界面来的波列收集并展示在四个资料组内:共深度点、共爆炸点、共检波点和共炮检距。在这些资料组的每一种中,波列系按相对于它们的旅行时间排列的,因而就消除了构造和双曲线正常时差的影响。对波列的适当平均和分析,便可从每一反射界面导出与下述有关的概念:①作为共深度点、炮检距、爆炸点和检波器位置函数的振幅和波形性质;②属于双曲线正常时差的剩余旅行时间为炮检距、爆炸点位置和检波器位置的函数。这一概念能为下述情况提供基础:①作为时间和空间函数的振幅控制和校正;②表层的静校正;③爆炸特征;④薄层、复杂异常、界面和岩性变化的指示;⑤为了确定速度对非双曲线时差加以解释并校正至最小旅程。
The Pleisto system is a special display of reflected seismic records. Wave columns from the reflection interface are collected and displayed in four data sets: common depth, common explosion, common detection and common offset. In each of these data sets, the wavelets are arranged relative to their travel time, thereby eliminating the effects of the construction and hyperbola normal time differences. Appropriate averaging and analysis of wave trains derives from each reflection interface the concepts related to: (1) Amplitude and waveform properties as a function of the common depth point, offset, explosion point, and detector position; (2) The remaining travel time for normal jet lag is a function of offset, explode point and detector position. This concept provides the basis for the following: control and correction of amplitude as a function of time and space; static correction of the surface; explosion characteristics; indication of thin layers, complex anomalies, interface and lithology changes; Determine the speed of non-hyperbolic time difference to be explained and corrected to the minimum journey.
