1、摘要FD33油田經(jīng)過7年的開發(fā),冃前已進入中含水階段,含水率已達到53%,該階段含水上升速度加快,產(chǎn)液量增加,產(chǎn)油量下降,開采難度增大,開采費用提高,是油田開發(fā)的重要階段。所以,必須對其含水上升規(guī)律進行研究并進行相關(guān)的調(diào)整抬施,以保證油IU能夠較長時間的高產(chǎn)穩(wěn)產(chǎn)。目前國內(nèi)常用水驅(qū)特征曲線法來研究水驅(qū)汕田的開發(fā)指標(biāo)。本文對常用的超過20種水驅(qū)特征曲線進行了分類總結(jié),并作岀了FD33油出的各類水驅(qū)特征曲線,通過9種常用水驅(qū)特征曲線預(yù)測了該油出的相關(guān)的開發(fā)指標(biāo),經(jīng)過分析對比選取了甲型水驅(qū)特征曲線的預(yù)測結(jié)果為最終預(yù)測結(jié)果。F
