【摘要】：靖邊高橋區(qū)及蘇里格南區(qū)于2011年投入規(guī)模開發(fā),2011年建產(chǎn)能8.26×108m3/a,2012年建產(chǎn)能12.22×108m3/a。試采分析表明蘇南及高橋下古氣井產(chǎn)能差別大,地層系數(shù)涉及范圍廣,表明儲(chǔ)層非均質(zhì)強(qiáng)。靖邊高橋及蘇里格南區(qū)投產(chǎn)時(shí)間短,處于開發(fā)初期,氣井生產(chǎn)規(guī)律還需進(jìn)一步摸索,盡管關(guān)于氣井和氣藏動(dòng)態(tài)分析方面的文獻(xiàn)較多,但針對(duì)該區(qū)復(fù)雜儲(chǔ)層條件和開采條件下的綜合系統(tǒng)評(píng)價(jià)方法的研究卻較少,未形成動(dòng)態(tài)分析技術(shù)系列;該區(qū)下古氣井受儲(chǔ)層非均質(zhì)性影響,氣井產(chǎn)氣能力和產(chǎn)水特征差異大,生產(chǎn)管理難度大。投產(chǎn)氣井生產(chǎn)動(dòng)態(tài)顯示,下古生界氣井單井產(chǎn)量高、產(chǎn)氣能力強(qiáng),但存在產(chǎn)能差異大、水氣比大、壓力下降較快、遞減率大等問題。為了科學(xué)有效地開發(fā)利用下古氣藏,合理評(píng)價(jià)下古生界氣藏開發(fā)潛力,正確認(rèn)識(shí)下古氣井生產(chǎn)特征,需要充分應(yīng)用試氣、試采及投產(chǎn)氣井的生產(chǎn)動(dòng)態(tài)資料,分析下古氣井的生產(chǎn)規(guī)律,建立下古氣井分類標(biāo)準(zhǔn),明確不同類型井生產(chǎn)動(dòng)態(tài)特征及穩(wěn)產(chǎn)能力,進(jìn)而優(yōu)化下古氣井生產(chǎn)工作制度,確定氣井合理配產(chǎn),方可為提高該地區(qū)下古氣藏整體開發(fā)效果提供指導(dǎo)。該項(xiàng)目主要從下古氣井動(dòng)靜態(tài)資料入手,以下古氣井試氣、試采、生產(chǎn)動(dòng)態(tài)資料為主,進(jìn)行生產(chǎn)規(guī)律綜合性研究,開展下古氣井產(chǎn)能評(píng)價(jià)、不同類型氣井生產(chǎn)規(guī)律研究、進(jìn)行下古氣井合理配產(chǎn)研究、開展氣井動(dòng)儲(chǔ)量及可采儲(chǔ)量評(píng)價(jià),進(jìn)行氣井遞減規(guī)律判識(shí)及遞減率評(píng)價(jià),進(jìn)行氣田開發(fā)指標(biāo)評(píng)價(jià),這些成果的取得,將為氣田下步的開發(fā)與管理提供科學(xué)、合理依據(jù)。建立了蘇南及高橋氣井一點(diǎn)法產(chǎn)能計(jì)算經(jīng)驗(yàn)公式,復(fù)算蘇南氣田61口下古井平均無阻流量23.24×104m3/d(靖邊下古平均無阻流量25.62×104m3/d),9口生產(chǎn)層位馬五5、馬五6井平均無阻流量79.10×104m3/d,其余53口井平均無阻流量13.57×104m3/d。高橋氣田35口井平均無阻流量5.64×104m3/d。
[Abstract]:Jingbian Gaoqiao District and Sulige South District went into large-scale development in 2011, with production capacity of 8.26 脳 108 m3 / a in 2011 and 12.22 脳 108 m3 / aa in 2012. The analysis of production test shows that the productivity difference of the ancient gas wells in south Jiangsu and Gaoqiao is great, and the formation coefficient involves a wide range, which indicates that the reservoir is heterogeneity. Since the production time of Jingbian Gaoqiao and Sulige Southern District is short, the production law of gas wells needs to be explored further in the early stage of development, although there are many literatures on gas well and gas reservoir performance analysis. However, there are few researches on the comprehensive system evaluation methods under complex reservoir conditions and exploitation conditions, and no dynamic analysis technique series has been formed. The lower paleogas wells in this area are affected by reservoir heterogeneity, and there are great differences in gas production capacity and water production characteristics of gas wells. Production management is difficult. The production performance of the gas wells in production shows that the lower Paleozoic gas wells have high production rate and strong gas production capacity, but there are some problems such as large productivity difference, large water-gas ratio, rapid pressure decline and large decline rate. In order to develop and utilize the Lower Paleozoic gas reservoir scientifically and effectively, evaluate the development potential of the Lower Paleozoic gas reservoir reasonably, and correctly understand the production characteristics of the lower Paleozoic gas well, it is necessary to make full use of the production performance data of the gas test, production test and production wells. The production law of lower ancient gas well is analyzed, the classification standard of lower ancient gas well is established, the production dynamic characteristics and stable production ability of different types of wells are defined, and the production working system of lower ancient gas well is optimized, and the reasonable distribution of gas well is determined. It can provide guidance for improving the overall development effect of lower paleo-gas reservoir in this area. This project mainly starts with the dynamic and static data of the lower ancient gas well, the following ancient gas well test gas, the test production, the production dynamic data mainly, carries on the production law synthesis research, carries on the lower ancient gas well productivity evaluation, the different type gas well production law research, The reasonable production allocation of lower ancient gas wells, the evaluation of dynamic reserves and recoverable reserves of gas wells, the recognition of the law of gas well decline and the evaluation of decline rate, and the evaluation of gas field development indexes are carried out. It will provide scientific and reasonable basis for the next development and management of gas field. The empirical formula of one-point productivity calculation for South Jiangsu and Gaoqiao gas wells is established. The average unobstructed flow rate of 61 lower ancient wells in Sunan gas field is 23.24 脳 10 ~ 4 m ~ (3 / d) d (average unobstructed flow rate of 25.62 脳 10 ~ (4) m ~ (-3) / d ~ (-1) in Jingbian (9 production zones, Ma Wu ~ (6) well, 79.10 脳 10 ~ (4) m ~ (3) 路d ~ (-1), and 13.57 脳 10 ~ (4) m ~ (-3 / d) of the remaining 53 wells. The average unobstructed flow rate of 35 wells in Gaoqiao gas field is 5.64 脳 104 m3 / d.
