1、東北石油大學(xué)本科生畢業(yè)設(shè)計(jì)(論文)摘 要隨著經(jīng)濟(jì)的持續(xù)、快速、健康的發(fā)展,國(guó)民經(jīng)濟(jì)對(duì)原油的需求以每年5%~6%的速度增長(zhǎng),而中國(guó)陸上已開(kāi)發(fā)油田的地質(zhì)儲(chǔ)量中特低滲透油藏儲(chǔ)量約占10%,已探明未動(dòng)用儲(chǔ)量中有一半以上是特低滲透儲(chǔ)量,這就迫切需要對(duì)特低滲透油藏進(jìn)行有效的開(kāi)采,滿足國(guó)內(nèi)對(duì)石油的需求。同時(shí)近幾年來(lái),油價(jià)的不斷攀升,也為特低滲透油藏的開(kāi)發(fā)創(chuàng)造了經(jīng)濟(jì)上的可行性。本文是在調(diào)研國(guó)內(nèi)外特低滲透油藏注水開(kāi)發(fā)技術(shù)的基礎(chǔ)上,對(duì)特低滲透油藏注水開(kāi)發(fā)的開(kāi)采特征、存在的問(wèn)題和影響因素做了闡述和分析,并利用數(shù)值模擬方法對(duì)超前注水、周期注水兩種開(kāi)發(fā)方法進(jìn)行了研究,分析了其影響參數(shù)。分析了特低滲透油田注水礦場(chǎng)開(kāi)發(fā)的
2、實(shí)例,從而確定了同步注水的基礎(chǔ)上,通過(guò)超前注水和周期注水技術(shù)可以有效地開(kāi)發(fā)特低滲透油藏,保持特低滲透油藏較高的地層壓力,并最終提高石油采收率。最后闡述了特低滲透油藏其它有效的開(kāi)發(fā)方式。關(guān)鍵詞:特低滲透;注水;超前注水;周期注水東北石油大學(xué)本科生畢業(yè)設(shè)計(jì)(論文)AbstractWiththehealthyandstabledevelopmentoftheeconomy,thedemandforcrudeoilisincreasingatthespeedof5%-6%peryear.Buttheultra-lowpermeabilityaccountsfor10%ofthegeologicalr
