锦16块兴隆台油层欢2-22-5井区微球调驱研究

Study on microsphere profile control in Huan2-22-5 well block of Jin-16 Xinglongtai reservoir

锦16兴隆台油藏目前水驱渗流优势通道明显,进一步扩大水驱波及体积空间较小。微球颗粒可在地层孔喉中膨胀,从而逐级改变液流方向,扩大波及体积。

Currently,prevailing channel for water flooding seepage flow in Jin-16 Xinglongtai reservoir is remarkable,andthe swept space volume in further expanding water flooding is very small. Microsphere can expand in the formation of pore throat andthen gradually change the direction of liquid flow,and finally expand swept space volume.
