In the process of seismic data interpretation in the west slope of the northern songliao basin, lots of strata overlap had been meet and pinch out. Using the LandMark explain software for lithologic horizon interpretation will spend a lot of energy. Fortran programming language had been used to process the horizon files of Land-Mark. Because of this, the horizon interpretation of the accuracy and efficiency is improved.%在松辽盆地北部西部斜坡地区地震资料解释遇到大量地层超覆、地层尖灭情况.而利用LandMark解释软件进行岩性层位解释时必然会耗费大量的精力.利用Fortran语言编程对LandMark中的层位文件直接进行处理,提高了层位解释的精度与效率.
