双河油田位于鄂尔多斯盆地伊陕斜坡的中部.主要油层组长6储集层的平均孔隙度为12.05％,平均渗透率为0.992×10-3 μm2,属特低渗储层.双河油田油藏原始地层压力和气油比均较低,油藏的天然能量有限.从分析双河油田注入水与地层水的特性、敏感性实验、配伍性实验等方面的研究.来保证注入水质满足油藏对注入水水质要求,保护储层,为提高注水开发效果及油田注水工艺方案提供重要的依据.%The field is located in the Ordos Basin Shuanghe Yishan in the middle slopes. Head of the main reservoir 6, the average reservoir porosity is 12. 05% and average permeability is 0. 992 × 10-3 μm2, is a low permeability reservoir. Shuanghe oil and gas reservoir of oil than the original formation pressure was lower, the natural reservoir of energy is limited. Based on the analysis Shuanghe Injected water and formation water properties, sensitivity test, ompatibility test and other aspects of research are researched. To ensure the injection of water into the reservoir to meet water quality requirements, reservoir protection, to enhance the effect of water injection and water flooding techniques provide an important basis for the program are presented.
