摘　　要：河南油田张店白秋区、下二门Ⅰ断块等稀油藏因边水推进造成含水迅速上升、产量下降快。开展了稀油藏氮气泡沫抑制边水技术研究,包括起泡剂筛选与评价,稳泡剂筛选与评价,氮气泡沫油藏适应性研究,施工工艺参数优化研究。形成了稀油藏氮气泡沫抑制边水工艺技术,在减缓边水浸入的同时实现了油井降水增油的目的。The thin oil reservoir blocks in Henan oilfield,such as Zhangdian Baiqiu and Xia-er-men areas,with the edge water advancing causing the problem of water cut rising rapidly and fast pro-duction decline.Thin oil reservoir of nitrogen foam inhibiting edge water technology research was carried out,including foaming agent selection and evaluation,stable foam agent selection and eval-uation,nitrogen foam reservoir adaptability research,construction process parameters optimization research.The technology of thin oil reservoir of nitrogen foam inhibiting edge water was formed, which can slow down the edge water immersion and achieve the purpose of well water rate drop-ping and oil production increasing at the same time.
