摘　　要：在施工中 ,注入压力的控制很重要 ,如果控制过高 ,低渗透层受到严重损害 ,达不到封堵高渗透层、启动低渗透层的目的 ;如果控制过低 ,挤入总量往往达不到深度调剖的目的。特别是对于非均质性严重的砾岩油藏来说 ,注入压力的控制显得更为重要。通过对深度调剖施工参数设计、现场施工的总结 ,发现砾岩油藏调剖压力(特别是深度调剖时 )的设计存在不足 ,针对砾岩油藏调剖 ,提出了一种简单、实用的确定注入上限压力的方法 ,即运用注水井试井曲线确定调剖注入压力上限值。During operation of depth profile control,the control of injection pressure is very important.If pressure is higher,low permeable formation will be seriously polluted,the goal of plugging high permeable formation and starting low permeable formation can't be achieved.If pressure is lower,the goal of depth profile control can't be achieved.Especially,to heterogeneity serious conglomerate reservoir,the control of injection pressure is more important.On the basis of the design of depth profile control parameter and summarizing field operation experience,the profile control pressure design of conglomerate reservoir has some shortages and a simple and practical method which determines the maximum pressure of injection by using well testing curve is proposed.
