摘要
从理论和实际应用的角度讨论了地震分辨率的概念及其影响地震分辨率的各种因素,指出地震分辨率决定了构造成图的精度,但在一定的条件下,对一些特定的地质体和标志层构造成图精度又有其特定的内涵;而在砂体描述的过程中,无论是用波阻抗剖面,亦或是道积分剖面,还是“相面法”,都必须在地震剖面可分辨的前提下,在地震剖面上可分辨的不同信息对砂体描述的不同过程和内容具有不同的作用。
The concept of seismic resolution and the affected factors are discussed in view of theory and practical application.The study shows that it is seismic resolution that controls the accuracy of structural mapping,but for some special geologic bodies and marker horizons under a certain condition,their accuracies of structural mapping exist spec-ified connotations.For the process of sand body description,whether wave impedance profile,trace integration profile,or phase-interference method have to be used under the requisite of resoluble seismic signals,because different resolu-ble seismic information have different effects on different processes and contents of sand body description.
