摘要
实践中发现,煤层的反射强度与厚度有直接关系,石油地震勘探中反射层位与钻井地质深度比较往往有较大的误差,本文认为地震反射是一种地层性质的综合效应:同时用过渡层对称层的理论以及超薄层的概念对反射加以分析,得出一致的结论,反射的这种综合效应在煤厚预测、找油地质勘探设计等工作中有一定的应用价值。
We know from practice that the reflection strength is closely associated with the thickness of the coal seam. In oil-seismic-exploration, we often found that there was a striking difference between the depth of the reflection horizon and the depth of drilling. Hence we hold that what the seismic reflection mirrors is the comprehensive effects of the strata. The above comprehension has been verified by using the theories of transitional layer, symm-atrical layer as well as the concept of ultra thin layer to data-interpretation Hopefully, such a comprehensive effects might be a usefull fool in predicting the thickness of the coal seam and in searching for oil and gas.
