最短路径层析成像技术在井间地震中的应用
|
摘要
利用基于最短路径树弯曲射线追踪的联合迭代重建层析成像(SIRT)技术进行井间地震层析成像。从方法原理、算法的有效性、数值模型和野外实际资料的层析反演等方面,对SIRT井间地震层析成像技术进行了系统研究。数值模型和野外资料的反演结果表明,该方法可靠稳定,收敛性好,层析成像结果的精度较高。
This paper adopts simultaneous iterative reconstruction technique (SIRT) to perform the crosswell tomography based on shortest path tree (SPT) curved ray tracing. The SIRT tomography was discussed in detailed in terms of principles and methodology, and validity of algorithm. Inversions on numerical model and real data showed that the method is reliable, stable and convergent, and the inverted results are of high precision.
