| 摘 要： | 渤海油田于2005年11月开始实施AY井组聚合物驱油试验。实施聚驱时,该井组的综合含水率已上升至57.9%,聚驱后含水上升速度得到有效控制,效果明显。但是,注聚实施过程中遇到了一些问题：外围注水井B-14、A-12和A-13因提高注入量,导致注入水向A-1、A-4、A-2井突进,使这些井含水率上升了10.0%～22.2%;周围注聚井A-7、A-6等井的聚合物沿高渗透层向中心井AY突进,导致中心井含水率上升了32%,聚合物产出浓度上升了150 mg/L左右。通过措施调整,如外围注水井B-14、A-12和A-13转注聚、中心区块聚合物注入浓度由1 750 mg/L提高到2 500mg/L等,使得一些前期受外围注水井影响的井的含水率下降了8%左右,而且使中心井的含水率下降16%左右,聚合物产出浓度下降了100 mg/L左右。这些措施有效抑制了外围注水井突进及中心井聚驱突进,保障了聚驱开发的效果。

| Abstract: | The polymer technology pilot test for AY well pattern was initialed in November,2005 in Bohai oilfield.The water cut of well pattern rose to 57.9% before polymer flooding.The increase of water cut was effectively controlled after polymer flooding trial.However,it encountered with some problems in the process of polymer injection,such as water cut of well A-1,A-4,A-2 increased by 10.0%～22.2% because water injection rate of external injection well B-14,A-12 and A-13 was enhanced which led water breaking through into well A-1,A-4,A-2.On the other hand,polymer from circumjacent well A-7,A-6 and other wells broke through to well AY.Water cut of well AY increased by 32% and polymer concentration increased by 150 mg/L.Measures such as transferring external water injection wells such as B-14,A-12 and A-13 to polymer injection wells and enhancing polymer concentration of central block from 1 750 mg/L to 2 500 mg/L were taken to decrease water cut of wells influenced by external water injection wells by 8%.On the other hand,water cut of the center well drop down by about 16% and output polymer concentration decreased by about 100 mg/L.Those measures effectively inhibited water breaking through and ensured good impact of polymer flooding development. |
