聚合物微球在共聚过程中材料加入AMPS等提高微球的耐温性能,根据PI决策排序表,用PI值筛选先期调剖的井号,利用成熟的冻胶、预交联颗粒等防窜剂封堵油水井间的窜流通道,提高水井的PI值和FD值,堵窜后或者PI90大于平均值的水井采用交联聚合物微球在线调驱工艺,用FD值优化微球的“四个度”。这种“窜堵远驱”的施工模式符合国内的堵调趋势,是国内堵调工艺的一个亮点。实施后井组稳产基础增强,自然递减下降。
Polymer microspheres in the copolymerization process, such as adding AMPS material to improve the microspheres temperature resistance performance, according to the PI decision order table, with PI value screening profile number of the first phase, the use of mature jelly, pre-crosslinked particle anti-channeling Agent blocking oil and water channeling channel between the wells to improve the PI and FD value wells, blocking channeling or PI90 is greater than the average value of the cross-linked polymer microspheres on-line control process using FD value optimization microsphere “Four degrees ”. This “channeling plug Far ” construction mode in line with the domestic plugging trend, is a highlight of the domestic plugging process. After the implementation of well-based group to increase production stability, natural decline decreased.
