| 摘 要： | 长庆油田超低渗透油藏由于渗透率低、非均质性强,在注水开发过程中,注不进、注不够水井较多,对油田长期稳产带来很大影响,采用常规增注措施存在措施有效期短的问题,为此,在超低渗透油藏应用了电脉冲解堵增注技术。这是通过在井下电子脉冲装置,产生低频脉冲波作用于油层,液体中高压放电处理地层的一种技术,特点是利用电子脉冲装置产生的强大冲击波,解除近井地带污染,达到解堵、增注的目的。通过现场应用10口井,取得了较好的增注效果。

| Abstract: | Due to ultra low permeability and strong heterogeneity in Changqing Oilfield reservoir,water can not be injected into many wells or enough water can not be injected in water injection development,which will result in serious effect on stable oil production for a long time.If adopted is the conventional measure for injecting more water into wells,its period of validity will be short.Therefore,adopted is the electronic pulse stimulation injection technique in ultra low permeability reservoir.In this technique... |
