【摘要】：作為我國(guó)“川氣東輸”的主要供氣源,P氣田位于我國(guó)川東北地區(qū),氣田的開(kāi)發(fā)建設(shè)對(duì)我國(guó)經(jīng)濟(jì)發(fā)展、能源的安全、能源的結(jié)構(gòu)調(diào)整、自然環(huán)境的保護(hù)、居民生活保障等具有十分顯著的意義。P氣田具有高壓、高產(chǎn)、埋藏深等特點(diǎn),其生產(chǎn)動(dòng)態(tài)規(guī)律極其復(fù)雜,而產(chǎn)能評(píng)價(jià)又是整個(gè)氣藏生產(chǎn)動(dòng)態(tài)描述的重要內(nèi)容。氣井產(chǎn)量的過(guò)大或者過(guò)小都會(huì)降低開(kāi)發(fā)效益,因此為保證氣田穩(wěn)定長(zhǎng)期生產(chǎn),正確合理地對(duì)其進(jìn)行產(chǎn)能評(píng)價(jià)顯得尤為重要。本文主要以P氣田生產(chǎn)動(dòng)態(tài)資料為基礎(chǔ),從產(chǎn)能評(píng)價(jià)和合理配產(chǎn)兩個(gè)方面進(jìn)行研究,主要研究?jī)?nèi)容如下：(1)對(duì)試氣和開(kāi)發(fā)過(guò)程中的氣井回壓試井、修正等時(shí)試井等資料進(jìn)行二項(xiàng)式和指數(shù)式分析,對(duì)異常測(cè)試資料進(jìn)行校正處理,并以此為基礎(chǔ)建立適合P氣田的氣井產(chǎn)能預(yù)測(cè)一點(diǎn)法經(jīng)驗(yàn)公式。(2)以當(dāng)前生產(chǎn)動(dòng)態(tài)資料為基礎(chǔ),運(yùn)用穩(wěn)定滲流理論、穩(wěn)定點(diǎn)產(chǎn)能分析方法、動(dòng)態(tài)產(chǎn)能評(píng)價(jià)方法、新建一點(diǎn)法和地層產(chǎn)水影響的產(chǎn)能預(yù)測(cè)法等方法對(duì)氣井產(chǎn)能進(jìn)行預(yù)測(cè)。(3)利用無(wú)阻流量經(jīng)驗(yàn)法、攜液臨界流量法、采氣指示曲線法、節(jié)點(diǎn)分析法、最優(yōu)化配產(chǎn)法、數(shù)值模擬法等配產(chǎn)方法,依據(jù)當(dāng)前產(chǎn)能預(yù)測(cè)結(jié)果對(duì)氣井進(jìn)行配產(chǎn)研究,在合理高產(chǎn)的需求下,確定氣井的合理配產(chǎn)結(jié)果。本文以生產(chǎn)動(dòng)態(tài)資料和產(chǎn)能測(cè)試資料分析為基礎(chǔ),采用多種方法較準(zhǔn)確的預(yù)測(cè)了氣井當(dāng)前產(chǎn)能大小和氣井合理配產(chǎn)產(chǎn)量,研究成果為氣田持續(xù)穩(wěn)產(chǎn)、高產(chǎn)具有一定的參考意義。
[Abstract]:As the main source of gas supply in China, the gas supply gas field is located in northeast Sichuan. The development and construction of gas field is beneficial to our country's economic development, energy security, energy structure adjustment and natural environment protection.P gas field has the characteristics of high pressure, high yield and deep burial, its production dynamic law is extremely complex, and productivity evaluation is the important content of the whole gas reservoir production performance description.Too large or too small production of gas wells will reduce the development benefit, so it is very important to evaluate the production capacity correctly and reasonably in order to ensure the stable long-term production of gas fields.Based on the production performance data of P gas field, this paper mainly studies on productivity evaluation and rational production allocation. The main research contents are as follows: 1) back pressure test of gas well during gas test and development.The modified isochronous well test data are analyzed by binomial and exponential formulas, and the abnormal test data are corrected and processed. Based on this, the empirical formula of one-point method for predicting gas well productivity in P gas field is established, which is based on the current production performance data.Using the theory of steady seepage, the method of productivity analysis of stable point, the method of dynamic productivity evaluation, the method of establishing a new point and the method of predicting the productivity of gas wells affected by formation water production, etc.) using the experience method of unobstructed flow, the method of critical flow rate of carrying liquid, etc.According to the current productivity prediction results, the production distribution of gas wells is studied, and the reasonable production distribution results of gas wells are determined under the reasonable demand of high production under the condition of reasonable and high production demand, such as gas recovery indicator curve method, node analysis method, optimal production allocation method, numerical simulation method, and so on.Based on the analysis of production performance data and productivity test data, this paper uses various methods to accurately predict the current production capacity of gas wells and the reasonable production ratio of gas wells. The research results are of certain reference significance for the sustained and stable production of gas fields.
