1、中文摘要論文題目：榆林南區(qū)山2氣藏氣井產(chǎn)能核實(shí)及開發(fā)指標(biāo)預(yù)測(cè)專業(yè)：油氣井工程碩士生：王刪㈣幽習(xí)縫指導(dǎo)教師：聶翠平(簽名)一李天太(簽名)摘要榆林南區(qū)山2氣藏是低滲透氣藏，從氣田高效開發(fā)思路出發(fā)，強(qiáng)化氣田開發(fā)動(dòng)態(tài)分析是非常有必要的，氣田開發(fā)動(dòng)態(tài)分析的核心是氣井產(chǎn)能核實(shí)和開發(fā)指標(biāo)預(yù)測(cè)。本文應(yīng)用穩(wěn)定“一點(diǎn)法”進(jìn)行氣井產(chǎn)能核實(shí)，該方法可以節(jié)約大量的測(cè)試費(fèi)用。同時(shí)求得了準(zhǔn)確和有效的單井無阻流量。穩(wěn)定“一點(diǎn)法”求氣井產(chǎn)能的關(guān)鍵是計(jì)算壓力參數(shù)，本文優(yōu)選了井底流壓計(jì)算模型，修正了計(jì)算的井底靜壓，并求得氣井無阻流量。本文應(yīng)用數(shù)值模擬技術(shù)來預(yù)測(cè)氣井開發(fā)指標(biāo)
2、，采用了Schlumberger公司的Eclipse2005a油氣藏?cái)?shù)值模擬軟件預(yù)測(cè)了榆林南區(qū)的開發(fā)指標(biāo)。研究結(jié)果表明，適用于低滲透氣田產(chǎn)能方程為二項(xiàng)式產(chǎn)能方程，榆林南區(qū)山2氣藏，處于開發(fā)中期階段，可以通過生產(chǎn)動(dòng)態(tài)來計(jì)算氣井產(chǎn)能，應(yīng)用經(jīng)驗(yàn)法和采氣曲線法進(jìn)行配產(chǎn)；結(jié)合生產(chǎn)動(dòng)態(tài)和靜態(tài)地質(zhì)資料進(jìn)行產(chǎn)能核實(shí)。計(jì)算結(jié)果表明：I類、II類氣井具有較長(zhǎng)的穩(wěn)產(chǎn)期和較高的產(chǎn)量，III類氣井幾乎沒有穩(wěn)產(chǎn)期，日產(chǎn)氣量不足1萬方。本文應(yīng)用數(shù)值模擬技術(shù)對(duì)榆林南區(qū)山2氣藏進(jìn)行儲(chǔ)量擬合和生產(chǎn)動(dòng)態(tài)擬合，在此基礎(chǔ)上，給出榆林南區(qū)山2氣藏開發(fā)指標(biāo)。研究結(jié)果對(duì)榆林南區(qū)山2氣
