摘　　要：临盘油田复杂小断块油藏已进入中后期开发阶段 ,调剖效果逐年变差。为此 ,在L10 6— 1断块中渗非均质油藏开展了交联聚合物深部改流矿场试验研究。介绍交联聚合物的作用机理、性能特点 ,并结合油藏实际情况 ,优化施工参数。通过在L10 6-1断块的L10 6-4井应用 ,水井油压上升了 2MPa ,PI值上升了 2 .6MPa ,吸水剖面得到了改善 ,对应油井累计增油 1678t,效果显著。The small fault-block reservoir has already come into middle-later time developing stage in Lingpan Oillield,and the effect of profile control is successively becoming worse.Therefore,the field test of deep flow alternation is done by using crosslinked polymer in L106-1 fault block,a moderate permeator,heterogeneous reservoir.The paper presents the function mechanism and properties of crosslinked polymer.And in combination with practical condition of reservoir,the operation parameters are optimized.Through application of reservoir deep flow alternation technology in well L106-4 in L106-1 fault block,oil pressure has risen 2 MPa,the value of PI 2.6 MPa.And the injection profile is greatly modified,and cumulative incremental oil is 1678 t.
