摘　　要：针对河南油田泌125区薄互层特低纯总厚度比(0.28)普通稠油油藏蒸汽吞吐效果变差的实际,通过热敏分析、高温相渗分析、热水驱替试验及现场实验,证明热水(含污水)驱明显优于蒸汽吞吐,注入水的温度高于拐点温度效果较好,化学驱辅助以热水驱效果更好一些。建议采用热水(污水)驱并辅助以表面活性剂驱技术,为同类油田提高驱油效率和采收率及有效地解决污水外排问题提供典型范例。As the thickness of the thin interbedding in Bi 125 area of Henan oil field is especially small, the ratio of sand and rock is 0.28 and the effects of huff and puff for common thick oil reservoir have turned bad, through temperature-sensitive analysis, high temperature permeated analysis, hot water drive and spot test, the hot water, including sewage, drive has proved to be evidently superior to the huff and puff. If the temperature of injected water is higher that of inflection point, it bring about a better effect; once chemical drive is added, the result would be even more good. It is suggested that the hot water, or sewage, drive with aid of the surface activator drive technique should be adopted, which provides a typical example for raising drive oil efficiency and recovery ratio and effectively solving the problem of disposal of sewage in the similar reservoirs.
