河31断块优势渗流通道识别及治理方法

河31断块是胜利油区现河庄油田的主力开发单元，经过近30a的注水开发，已进入特高含水后期，平面和层间矛盾极为突出，水驱油效率低。为了改善断块的水驱开发效果，结合精细油藏研究成果及动态监测资料，在充分识别断块大孔道分布状况及剩余油潜力的基础上，利用储层优势渗流通道预测技术和堵水调剖技术挖掘油层潜力，充分动用剩余油富集区，取得了很好的效果。

Dominant flowing path identification and treatment in He31 fault block

He31 fault block is the principle developing block in Xianhezhuang oilfield of Shengli oil province,and has entered late high water cut stage after almost 30a of water flooding,both areal and inter-layer problems are very sharp,and water drive efficiency is low.In order to improve waterflooding effect of the block,dominant flowing path prediction and water shutoff profile control have been performed to produce residual oil according to fine reservoir study and dynamic monitoring data on the basis of fully understanding large pore-path distribution and residual oil potential.This has achieved very good result.
