1、摘要FD33油田經(jīng)過7年的開發(fā)，口前已進(jìn)入屮含水階段，含水率已達(dá)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(fèi)用提高，是油111開發(fā)的重耍階段。所以，必須對(duì)其含水上升規(guī)律進(jìn)行研究并進(jìn)行相關(guān)的調(diào)整措施，以保證油田能夠較長(zhǎng)時(shí)間的高產(chǎn)穩(wěn)產(chǎn)。0前國(guó)內(nèi)常用水驅(qū)特征曲線法來研究水驅(qū)油田的開發(fā)指標(biāo)。本文對(duì)常用的超過20種水驅(qū)特征曲線進(jìn)行了分類總結(jié)，并作出了FD33油［□的各類水驅(qū)特征曲線,通過9種常用水張?zhí)卣髑€預(yù)測(cè)了該油出的相關(guān)的開發(fā)指標(biāo)，經(jīng)過分析對(duì)比選取了1T型水驅(qū)特征曲線的預(yù)測(cè)結(jié)果為
