随着鄂尔多斯盆地石油资源的开发,为提高低渗透储层的采收率,开展对低渗透致密岩性储层的注水工艺技术的研究。通过对油套分注技术、空心集成分注技术、偏心分注技术等应用于低渗透致密岩性储层的注水技术的对比研究,结果认为桥式偏心注水技术和偏心注水技术是现阶段最有效的低渗透储层分层注水技术。在延长油田永宁采油厂的三口注水井组中应用桥式偏心注水以及偏心注水技术进行试验,均见到了增液、增油的效果。
隨著鄂爾多斯盆地石油資源的開髮,為提高低滲透儲層的採收率,開展對低滲透緻密巖性儲層的註水工藝技術的研究。通過對油套分註技術、空心集成分註技術、偏心分註技術等應用于低滲透緻密巖性儲層的註水技術的對比研究,結果認為橋式偏心註水技術和偏心註水技術是現階段最有效的低滲透儲層分層註水技術。在延長油田永寧採油廠的三口註水井組中應用橋式偏心註水以及偏心註水技術進行試驗,均見到瞭增液、增油的效果。

With continually development of Ordos basin and in order to enhance recovery factor, how to apply water injec-tion to develop low permeable tight reservoir became the most important work in the present research. The essay discusses and compares different water injection technology which applied to low permeable tight lithological reservoir. As a result, eccentric water injection and bridge-eccentric water injection are most effective methods of separate layer water injection which have been applied in three wells in Yong Ning exploiting oil factory and achieve incremental oil effect.
