摘要
近年来，相干体技术在地震勘探资料解释方面的应用有着重要突破。由于相干体处理的对象主要是三维地震数据体，传统的方法计算需要运行较长时间。为缩短解释周期，在研究算法分析的基础上，采用递推算法、乘幂法等，对传统的相干体算法进行了改进，大大地提高了计算速度。这里介绍了相干体技术的改进算法，在微机上开发出相干体分析软件，井在实际的三维地震体储层评价上得到成功的应用。测试证明，运算速度较常规方法提高了5—7倍，这充分表明了该方法的有效性。
With the 3D coherence cube technique,the seismic exploration has nearly made a new break through in the seismic data interpretation.By calculating coherency between seismic traces,we can realize the conversion from 3D amplitude data to coherence attribute data.As the running time of the traditional methods is,however,always very long,such methods cannot satisfy the practical need. In order to shorten the periods of the seismic data interpretation,the authors have improved the algorithm of the traditional coherence cube based on the analysis of the algorithm and adopted a series of methods such as recursive method,power algorithm,to advance the speed.The pager introduces the improved algorithms,and develops the software of coherence cube technique and applies the technique successfully to the evaluation of petroleum reservoir.By testing,the speed of calculating is increased to 5-7times faster which verifies the validity of the algorithms.
