摘　　要：针对飞雁滩油田开发中存在着注入水易沿优势流场窜进,开发效果变差的实际问题,研制了无机微粒聚合物凝胶深部调剖体系及施工工艺,并在飞雁滩油田埕126区块开展了9井次深部调剖现场应用,工艺成功率100%,对应油井见效率82.6%,累计增产原油30.018 8 kt,降水2.3×10~4 m^3,投入产出比1:8.21,取得了显著的经济效益。结果表明,采用无机微粒聚合物凝胶深部调剖技术,有效地调整了油藏非均质性,提高了储层动用程度,改善了注水开发效果。In view of the easy gushing of injecting water into Feiyantan oilfield, which has caused poor development effect, an predominant flow field in the development of inorganic particulate polymer gel deep profile control system and relevant construction technology were developed and applied at 9 oil wells in No. 126 Block of Feiyantan oilfield. The success percent of the technology was 100%, the effectiveness percent at corresponding oil wells was 82.6%, accumulated crude oil production increase was 30.018 8 kt, the amount of water gushed - in was reduced by 2.3 × 10^4 ms , and the input - output ratio was 1 ： 8.21, indicating this technology has good economic benefit. According to the results, the nonuniformity of oil reservoir can be adjusted effectively and the reservoir bed producing degree can be improved by this making use of inorganic particulate polymer gel deep profile control system, and it is an effective technology for improving water- flooding development of oilfield.
