吸水剖面是指水井各个层位对于注入水的分配比例，也是应用于调剖堵水，防止水窜，提高注入水在各个层位的波及系数，提高油层的驱油效率，从而提高采收率。
水井注入压力升高，吸水剖面得到调整，层间矛盾得到改善；
The injection pressure rose, the injectivity profile and interlayer contradiction was modulated.
对于注水开发油田，吸水剖面是油田动态分析和注水调整的重要依据。
For water injection oilfield, water injection profile date is very important to dynamic analyzing and adjuring water injection.
对于多油层非均质油藏，层间差异会导致吸水剖面不均匀，影响水驱效率。
In multilayer heterogeneous reservoir, the interlayer difference would lead to nonuniformity of injection profile and influence water displacement efficiency.
