本文针对常规聚合物如聚丙烯酰胺在调剖、调驱、三采使用过程中存在的耐温、耐盐、抗剪切性能的不足,利用新型缔合聚合物AP-P4的特殊分子结构及其抗温、抗盐、抗剪切优势,首次研究开发出了适合中原油田高温、高盐油藏的新型缔合聚合物调剖体系,筛选出了适合新型缔合聚合物调剖体系的酸度调整剂、交联剂MZ-YL、MZ-BE、MZ-XS,通过性能评价试验表明,该体系具有良好的增粘、耐温、耐盐、抗剪切和抗脱水特性。2003年率先在国内开展了新型缔合聚合物调剖现场试验26井次,取得了明显的增油降水效果。研制开发的新型缔合聚合物调剖体系及相关应用技术对高温、高矿化度油藏开展聚合物调剖具有指导作用。
In this paper, the conventional polymer such as polyacrylamide in the profile control, drive, three mining process used in the existence of temperature, salt, shear resistance, the use of the new association polymer AP-P4 molecular structure and It is the first time to research and develop a new type of associative polymer profile control system suitable for the high temperature and high salinity reservoirs in Zhongyuan Oilfield and to screen the acidity suitable for the novel associative polymer profile control system MZ-YL, MZ-BE and MZ-XS as modifiers and cross-linking agents. The performance evaluation tests show that the system has good properties of viscosity increasing, temperature resistance, salt tolerance, shear resistance and dehydration resistance. In 2003, it took the lead in conducting 26 field tests of new associative polymer profile control in China and achieved remarkable oil precipitation effect. Developed a new associative polymer profile control system and related application technology for high temperature, high salinity reservoir polymer profile control play a guiding role.
