摘要
低渗透裂缝性油藏注水后,注入水容易沿裂缝窜进,油藏含水上升快,在较短时间内就进入高含水阶段。针对靖安油田长6油藏低渗透、裂缝性特点,提出了有针对性的稳产技术对策——预交联颗粒+交联聚合物复合深部调剖技术。通过油藏数值模拟,确定了调剖剂用量,预测了封堵半径,并评价了调剖效果。在此基础上,对注采井组进行了深部调剖施工方案的设计,通过复合深部调剖技术的现场应用,取得了较好的增油效果。研究成果为低渗透裂缝性油藏控水增油技术的研究和矿场应用做了有益的探索,具有一定的借鉴指导意义。
Aimed at Jing′an Reservoir in Changqing Oilfield which is characterized by low permeability fracture,this paper researches the growth actuality and regulations of fractures,and analyzes water-flooding status and the reasons of producing water by using numerical simulation technology.Through field application,we have obtained obvious oil-increase effect.The achievement establishes firm theory foundation for the research and field application of water-control and oil-increase technology of low permeability fractured reservoir,and accumulates abundant practice experiences,so it has important theory and spread application value.
