The Research of Water Flooding Measures in Late High Water Cut Period of Secondary Reservoirs

Abstract:

Daqing oilfield is in high water cut stage and always appears two phenomenon called "two speeds" and "two low". Based on the geological characteristics of the block, the current exploration wells arrangement and producing dynamics, two sets programs of water injection intensity and water injection timing were designed. Through the numerical simulation prediction of the two sets of 16 programs, the optimization results are 9 injection intensity and 93% of water cut. The cumulative oil producing capacity is 1402.41×10⁴t and the cumulative increasing oil capacity is 6.26×10⁴t and the increasing value of the recovery efficiency in Secondary oil layer is 1.33% when the water cut is 98%.
