摘要
本文叙述了胜利油田近几年对堵水调剖技术的研究、实践及成效。重点阐述了用粘土颗粒堵剂封堵大孔道、整体调剖，低渗砂岩油藏的堵水调剖等方面的研究与试验成果，说明了堵水调剖对“控水稳油”的重要作用。在对胜利油田油藏的水淹特点及各类堵剂的性能和适应性进行研究与分析的基础上，提出并实践了不同类型油藏的不同的堵水调剖模式。
his paper expounds the research,practices and effects of profile control by water pluggingtechniques that have been used in Shengli oil fields in recent years, emphasizing the studies andtest results of general profile control by plugging large pore paths with clay-particle pluggingagents and profile control by plugging water in low permeable sandstone reservoirs,showing theimportant role of profile control by plugging water in stablizing oil production by water control.Different modes of profile control by water plugging in different types of oil reservoirs have beenput forward and put into practice according to the properties of watered Out reservoirs andproperties and applicabilities of various plugging agents.
