聚合物驱细分复合解堵技术的研究与应用

Study and Application on Subdividing Complex Blocking Removal Technique for Polymer Drive

聚合物驱细分复合解堵技术中的复合解堵剂配方不但能将HPAM的C-C键主链彻底氧化分解,而且具有极强的杀菌、除硫和解除无机垢类堵塞的能力,而细分注入工艺则提高了解除聚合物地层堵塞的针对性。该技术注入工艺简单,成本低廉。现场试验表明,该技术可有效解除聚合物驱有机和无机堵塞,平均有效期在8个月以上,增油效果显著,是解除聚合物驱地层堵塞的一种新方法。

The complex blocking remover formula in complex blocking removal subdivision technique can not completely oxidize and decompose the main chain of C - C key in HPAM, and it has strong ability in disinfection, sulphur removal and inorganic scale removal, while subdivision technique will directly aim at blocking removal in polymer formation . This technique is featured by simple injection process and low cost. The field test shows that it can effectively remove the organic and inorganic blocking of polymer drive, with the average validity period of more than 8 months, achieving remarkable oil incremental efficiency, it' s a new method to remove polymer drive formation blocking.
