摘　　要：在高分辨率地震资料的基础上,对H12井区建立高频格架,结合钻井分析,配合沉积相研究,分析岩性发育有利区。在岩性发育有利区进行细分层解释,优选目标砂体,通过多属性分析技术,准确地刻画出岩性体分布。运用谱分解技术对岩性体进行内幕刻画,与实际钻井结合预测有效储层的分布,为识别该类岩性圈闭总结出一套行之有效的方法。Based on high resolution seismic data, this paper set up the high frequency stratum frame of well area H 12. Then the advantaged area of lithosome was obtained combined with drilling analysis and sedimentary facies study. In the advantage area, by subdivided layer interpretation, target sand body optimization and muhiattribute analysis technique, the lithosome distribution was accurately described. Thereafter, by using spectral decomposition technology, this paper described the inner structure analysis of lithosome. Effective reservoir was obtained combined with actual drilling data. A set of effective methods for recognition of lithologic trap was summed up.
