摘　　要：测井资料是进行开发地质研究的重要资料,井网越密,对储层的沉积特征认识越精确。从沉积学原理出发,充分利用极为丰富的单井眼信息,通过对目前井网最密开发区ZQ(井网密度275口/km2)储层综合分析解剖,剖析井网加密前后砂体平面上、剖面上的变化,总结归纳井网加密后不同沉积环境砂体变化情况:河道宽度变化以内缩变窄为主,砂体组合形式由枝状向网状变化,平面相变迅速,砂体分布复杂化。研究结果进一步揭示了松辽盆地河流相储层发育特点。For the study of the development geology , the well logging data are the important materials.The more dense well network , the more precise understanding of reservoir sedimentary characteristics.In this paper the deposition theories were applied to dissect comprehensively oil-layers of high well-density ( 275 wells / km2 ) ZQ development zone by taking full advantage of the extremely rich well materials , the sand body plane and the profile changes after pattern infilling have been analyzed , and then the variation characteristics of the sand body have been summarized : Shrink narrow is primary for channel width variation , sand-body combining form changes from dendrite to mesh , Planar phase change quickly and the sand body distribution is complex.The results further reveal the fluvial facies reservoir in Songliao basin.
