1、摘要低滲透油田是指油層儲(chǔ)層滲透率低、豐度低、單井產(chǎn)能低的油田。隨著建設(shè)時(shí)間的延長(zhǎng)，低滲透油田普遍出現(xiàn)原油產(chǎn)量下降，綜合含水上升，地面系統(tǒng)布局不合理、負(fù)荷不平衡、設(shè)施腐蝕老化等問(wèn)題，需更新的站、所、設(shè)備設(shè)施、管線數(shù)量日益增多，導(dǎo)致生產(chǎn)運(yùn)行費(fèi)用、維修維護(hù)費(fèi)用和管理費(fèi)用逐年增高，不僅影響了油田的安全生產(chǎn)，同時(shí)影響了油田開(kāi)發(fā)的經(jīng)濟(jì)效益。在我國(guó)各大油田進(jìn)入開(kāi)發(fā)中后期、能源緊缺的情況下，加緊低滲透油氣的勘探開(kāi)發(fā)具有很重要的現(xiàn)實(shí)作用和戰(zhàn)略意義。中國(guó)低滲透油氣資源豐富，具有很大的勘探開(kāi)發(fā)潛力。近二十年來(lái)，在低滲透砂巖、海相碳酸鹽巖、火山巖勘探方面取得了很大的發(fā)現(xiàn)，形成了國(guó)際一流的開(kāi)發(fā)配套技術(shù)。低滲

2、透油氣田開(kāi)發(fā)成熟技術(shù)有注水、壓裂、注氣等。多分支井技術(shù)、地震裂縫成像和裂縫診斷技術(shù)、注氣提高采收率等新技術(shù)快速發(fā)展，發(fā)達(dá)國(guó)家低滲透油氣田開(kāi)發(fā)技術(shù)日趨成熟。本文主要介紹了當(dāng)前低滲透油藏的開(kāi)發(fā)技術(shù)。關(guān)鍵詞：低滲透油藏；油藏表征；油氣藏保護(hù)；欠平衡鉆井；井網(wǎng)部署.AbstacctReferstothelowpermeabilityoilfieldreservoirreservoir,lowpermeability,lowabundanceandlowsinglewellproductioncapacityoftheoilfield.Astheextensionofconstruction
