辽河油田锦16块开发已进入高含水、高采出程度的双高期。为了提高采出程度、降低综合含水,拟采用聚合物驱。该文对聚合物驱所用聚丙烯酰胺和黄胞胶做了对比和筛选,进行了增粘性、长期稳定性、剪切稳定性、过滤性、弱交联性和驱油效率等方面的实验研究,考察了两种水溶性聚合物对油藏及其流体的适应性。综合性能对比表明:两种聚合物均适合于锦16块聚合物驱,但黄胞胶更适合该油藏条件;黄胞胶注入过程中,建议使用浓度为1000mg/L;为了破坏凝胶菌丝体,需加入孔板进行剪切,以提高其注入能力
Kam 16 Liaohe Oilfield development has entered a high water cut, high mining level double high. In order to improve the degree of recovery, reduce the integrated water, it is proposed to use polymer flooding. In this paper, polyacrylamide and xanthan gum used in polymer flooding were compared and screened, and the experimental research on thickening, long-term stability, shear stability, filterability, weak crosslinkability and flooding efficiency , Investigated the suitability of two water-soluble polymers for reservoirs and their fluids. The comprehensive performance comparison shows that both polymers are suitable for the polymer flooding of Jin 16, but the xanthan gum is more suitable for the reservoir conditions; the recommended concentration of xanthum gum is 1000mg / L during the injection process; Silk body, need to join the orifice cut, in order to improve its ability to inject
