针对典型的低丰度、低渗透、低压力油藏的子北油田,存在天然能量不充足、渗流阻力大、稳产难以及常规注水开发效果差、采收率低等特点,认真分析超前注水机理,及在子北油田毛家河区超前注水开发科技示范区的试验,分析评价注水实施以来的初期效果,使油井保持较高压力水平,减少储层伤害等提高采收率。子北油田超前注水开发技术的成功应用,对于低渗透油田的开发具有一定的借鉴意义。
For the typical low-abundance, low-permeability, low-pressure reservoirs in the North Oilfield, there is insufficient natural energy, seepage resistance, stability and difficult to steady development and poor performance of conventional water injection, low recovery, careful analysis of advanced water injection mechanism , As well as the trial of advanced water injection technology demonstration zone in Maojiahe District of Zibei Oilfield to analyze and assess the initial effect since water injection was implemented so as to maintain the oil well at a higher pressure level and reduce the harm of the reservoir so as to enhance oil recovery. The successful application of advanced water injection development technology in Zubei Oilfield has certain reference significance for the development of low permeability oilfield.
