1、摘要河西務(wù)油田H斷塊油藏水驅(qū)開發(fā)兩年以來，暴露出了地層壓力水平低、油井見水后含水上升速度快的問題。為了解決該斷塊開發(fā)所暴露出的矛盾和問題，本文通過對(duì)H斷塊的地質(zhì)特征進(jìn)行深入研究；對(duì)開發(fā)效果進(jìn)行綜合評(píng)價(jià)；對(duì)H斷塊剩余油分布規(guī)律進(jìn)行分析；最后，在地質(zhì)特征、開發(fā)效果評(píng)價(jià)的基礎(chǔ)上，制定出合理的調(diào)整部署方案，能夠更好地指導(dǎo)油田生產(chǎn)和保持穩(wěn)產(chǎn)。本論文對(duì)H斷塊進(jìn)行了油藏地質(zhì)特征分析，對(duì)主要含油層段的儲(chǔ)層特征、非均質(zhì)性等特征進(jìn)行了研究。研究認(rèn)為儲(chǔ)層屬中孔中低滲透儲(chǔ)層，層間非均質(zhì)比平面的非均質(zhì)性強(qiáng)，儲(chǔ)層存在高滲透條帶，是造成油井快速水淹的主要原因。同時(shí)，本文對(duì)H斷
2、塊的生產(chǎn)特征及開發(fā)效果進(jìn)行了綜合評(píng)價(jià)，明確指出了該斷塊開發(fā)過程中存在著注采關(guān)系不對(duì)應(yīng)、油藏壓力水平低等問題。針對(duì)存在的問題提出了相應(yīng)的技術(shù)政策，包括合理井距、合理注采比、注采井?dāng)?shù)比的確定。最后制定了調(diào)整方案，提出了油井轉(zhuǎn)注、水井轉(zhuǎn)采、補(bǔ)孔、壓裂等調(diào)整措施。關(guān)鍵詞：油藏地質(zhì)特征；水驅(qū)效果評(píng)價(jià)；技術(shù)政策評(píng)價(jià)；調(diào)整方案iStudyontheEvaluationofDevelopmentEffectandtheAdjustingCountermeasureoftheHFault-blockReservoirinHexiwuOilfieldWangJuny
