| 摘 要： | 1998年在孤岛油田中二南，、中二中注聚合物区的一些低压注入井开展了聚合物加交联剂注入试验，由试验过程中资料分析发现，注入交联聚合物驱油段塞能显著提高油压，在增加地下的渗流阻力，扩大驱油的波及体积，提高采收率方面，较单纯的聚合物驱油有独特的优势。

| Abstract: | Additionalinjection of chromium crosslinker togethe r with polymer into several low injectionpressure wells was performed during enl arged polymer flooding tests at South C2 Oil fieldand part of Central C2 Oil fi eld of Gudao, Shengli, in June-Dec 1998. It was shown in thelaboratory experiment s and field tests that the polymer/crosslinker XL-2 floodingsolution forms in reservoir formations weak gel with significantly increased viscosityeven when t he solution presheared which leads to rising injection pressure and toenhanceme nt in oil recovery. |
