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。
The development of heavy oil in Henan Oilfield mainly adopts the method of injecting steam for steam stimulation. In order to further improve the recovery rate of heavy oil resources, an encryption well scheme is adopted. Through drilling coring, logging, commissioning shows that part of the heavy oil well has been flooded with steam water. Correct evaluation of heavy oil infill wells flooded layers and strength is to improve the production of heavy oil infill wells key. Through the research, a set of methods for evaluating the flooded layer of heavy oil infill wells by using well logging data is proposed, which is verified by production practice.
