摘　　要：针对塔河油田河道砂油气藏薄储层展布识别困难的问题,以阳探2井区为例,通过RGB分频混色和地层切片技术的综合运用,落实了井区河道砂薄储层平面展布范围和纵向叠加关系,刻画出井区河道砂储层发育4期次砂体共计6条河道。同时,利用实钻井油气成果验证了河道砂体平面刻画和纵向关系的准确性,取得了较好的储层预测效果,为井区高效开发和井网优化提供了依据。With the difficulty in identifing the distribution of channel sand reservoirs in Tahe Oilfield, we take Yan- gtan2 area as an example in this paper to carry out the research on the range and the superimposition relationship of the fluvial thin - reservoir, and determine 4 phases sand bodies with total 6 river channels through the RGB mixing frequency and stratal slice technique. The actual drilling data, which achieved good results, also proved the accu-racy of relationship between the range and the superimposition. These methods of reservoir forecasting provide a fa-vorable basis for efficient development and well pattern optimization in this area.
