靖安油田注水井深部调剖技术研究与应用的中期报告
摘要：
本文介绍了靖安油田注水井深部调剖技术的研究和应用情况。深部调剖技术是一种针对高渗透储层的开发技术，可以通过向储层注入高分子物质改变储层中的油水分布，提高油藏的采收率。靖安油田注水井深部调剖技术主要包括地层评价、开发设计、实验模拟、现场施工等环节，本文侧重介绍了实验模拟和现场施工部分的研究内容和成果。实验模拟以实验室压力采油仪为基础，模拟储层压力下的油水流动情况，并通过加入不同浓度的改性聚合物来研究其对油水分布的影响。现场施工主要包括注入改性聚合物、操作参数调整、采收率监测等环节，目前已经在靖安油田注水井中完成了前期的试验和调整，初步结果表明，深部调剖技术对提高油藏采收率有很大的潜力。
