摘　　要：针对复杂地层中地层对比所面临的难题,在广泛结合前人研究成果的基础上,提出了一套综合运用地震资料、测井资料、测试资料等所能提供的一切有用信息,进而达到精细地层对比的综合方法,即"标志层控制下的旋回对比、多平台多维结合及层面约束、井震结合"的地层对比方法。该方法利用了测井资料纵向上的高分辨率优势和地震资料横向上的优势,也考虑了沉积环境对地层的控制因素,同时结合三维显示技术,及时分析和掌握地层对比情况。该方法可为同类复杂地层油藏精细地层对比研究工作提供技术方法模式。Aimed at a series of difficulties about stratigraphic correlation in complicated formation,a method of correlation is proposed,which puts the stresses on the using of the data from seismic horizon,logging and dynamic performance. Good effects have been achieved in the application of this method for the fine stratigraphic classification.This method utilizes the advantages from logging data in the vertical seismic data in the horizontal direction to carry out the recognition and correlation of sand,also considered sedimentary environment and combined with 3D view technology,timely analyzing the result of stratigraphic correlation.The method of fine stratigraphic correlation for complicated formation is also fit for other oilfields with the same kind.
