摘要
为了扩大聚合物驱的波及体积 ,提高聚合物区块整体开发效果 ,注聚驱调剖时机应在注聚前或注聚初期 .调剖可封堵大孔道改善吸聚剖面 ,有利于后续聚合物驱动作用 .在中二南 Ng3 -4 注聚区块的注聚初期 ,运用 RE油藏工程调剖决策技术 ,实施调剖工艺 1 0井次 ,平均注入压力上升 5 .3 1MPa,和其它区块同期相比见聚井数下降 2 0 .6 % 。
Zhongernan area is one of five polymer oil displacement blocks in Gudao oilfield. In order to increase the swept volume of polymer oil displacement and improve the oil displacement result of the whole block, profile control should carry out before polymer oil displacement or in the early stage of it. Profile control can plug large pore passages and improve polymer entry profile, which is favourable to follow up polymer oil displacement. By means of RE reservoir engineering profile control decision technology, profile control was implemented on 10 wells in the block in the early stage of polymer oil displacement. The oil pressure of the wells increase averagely by 5.31 MPa. Compared with other blocks, the number of polymer breakthrough wells in the block decrease by 20.6% in the corresponding period.
