针对松辽盆地腰英台油田河流-三角洲沉积的储层具有非均质性强,注水开发后,储层动用不均衡的状况,以及常规注水开发已很难再提高采收率的难题,基于不稳定注水的机理,以DB34区块中部井组为研究对象,运用油藏数值模拟技术,研究不同注入强度和不同注入周期的不稳定注水,并制定相关技术政策。矿场试验表明不稳定注水效果明显,可以大幅度控制自然递减,提高注水效率,研究不仅为DB34区块进一步扩大不稳定注水试验范围,改善水驱开发效果,提高采收率提供了理论保障,同时对类似油藏开发具有重大的现实意义。
針對鬆遼盆地腰英檯油田河流-三角洲沉積的儲層具有非均質性彊,註水開髮後,儲層動用不均衡的狀況,以及常規註水開髮已很難再提高採收率的難題,基于不穩定註水的機理,以DB34區塊中部井組為研究對象,運用油藏數值模擬技術,研究不同註入彊度和不同註入週期的不穩定註水,併製定相關技術政策。礦場試驗錶明不穩定註水效果明顯,可以大幅度控製自然遞減,提高註水效率,研究不僅為DB34區塊進一步擴大不穩定註水試驗範圍,改善水驅開髮效果,提高採收率提供瞭理論保障,同時對類似油藏開髮具有重大的現實意義。

Yaoyingtai oilfield in a river deltas is of strong reservoir heterogeneity .After water flooding ,due to unbalanced reservoir situ-ation ,it is very difficult for Conventional water flood to enhanceoil recovery .Based on Unstable water -based mechanism ,taking block DB34 central well groups as study object ,this paper focuses on numerical reservoir simulation techniques ,different Strength and instability different injection cycle studies and the development of relevant technology policy .Field tests show that unstable water injection effect is ob-vious ,and can greatly control the natural decline ,improving water efficiency .This research not only provides theoretical basis for DB34 block further expansion of unstable water injection test range ,improving the water flooding ,but also has great practical significance in the same reservoir development .
