克拉玛依油田六中北克下组油藏二次开发效果技术研究

RESEARCH ON THE EFFCET OF SECONDARY DEVELOPMENT TECHNOLOGY IN NORTHERN LIU-ZHONG AREA IN TAK1 FORMATION RESERVOIR OF KARAMAY OILFIELD

针对六中区克下组砾岩油藏高渗层层位不固定,隔层发育差,胶结疏松,油水粘度比高,井点损失多,开发难度较大等问题,通过分区加密调整实施二次开发,主力小区六中北井区优化完善井网,采取不同油藏分类注水政策、精细注采调整,实现了油藏稳产。为克拉玛依油田其它油藏二次开发后的措施方案优选、注采单元的整体治理及提高开发效果具有重要指导意义。

According to problems in Liuzhong T2K1 formation Conglomerate Reservoir development process of Karamay Oildfield,such as Hypertonic formation Non-Fixing、interlayer poor development、the loose cementation、highly oil-water viscosity ratio、highly Well-point loss、great development difficulties and so on.By adjusting the secondary development of encrypted partitions and optimizing the well network,with a different reservoir classification of water policy and fine adjustment of injection,a stable oil recovery is achieved,which has imporcant guidance for other reservoirs development is karamay oil field.
