摘　　要：河南油田稠油开发主要采用注蒸汽吞吐的方式，为了进一步提高稠油资源的采收率，采用加密井方案。通过钻井取芯、测井、投产表明，稠油加密井部分已被蒸汽水水淹。正确评价稠油加密井水淹层位和强度是提高稠油加密井开采效果的关键。通过研究，提出了一套利用测井资料评价稠油加密井水淹层的方法，经生产实践验证效果较好。Steam huff and puff is the main recovery process of heavy oil in Henan Oilfield and infill producers are drilied in order to further increase heavy oil recovery factor. Coring, logging and production of infill wells demonstrate that some heavy oil infillers have been watered out by steam condensated water. Proper evaluation of the position and strength of watered-out zones is the key to improve recovery efficiency of infilled heavy oil wells. A series of methods that eva1uate watered-out zones in heavy oil infillers using log data are presented in this paper. Production practice demonstrate that they are effective.
