【 摘 要 】

Nine wells are on deep profile control in SaIII1-7 layer of Lamadian Oilfield North West block. Flexible diverting agent are be used to carry out high-dose and long slug deep profile control. Injection profile of injection wells are improved, the radius of plugging is expanded and the plugging efficiency is improved. It has certain adaptability to the profile control of thick layers, and can improve the condition of reservoirs absorption. It can reserve technology for large scale deep profile control on water flooding, and create a new way for high efficiency development the ultra-high water cut oilfield.
