【摘要】：世界能源消費(fèi)量的不斷激增與日益突出的供需矛盾明顯,上世紀(jì)九十年代后,人們逐漸重視起非常規(guī)天然資源,很多國(guó)家重要的議事中都提到了非常規(guī)油氣資源的勘探開發(fā),21世紀(jì)重要補(bǔ)充能源中,非常規(guī)油氣資源被列入其中。美國(guó)是最早開發(fā)頁巖氣的國(guó)家,目前在美國(guó)已經(jīng)取得成功,從世界范圍上來說,我國(guó)是頁巖氣資源量最豐富的國(guó)家,但是因?yàn)槲覈?guó)頁巖氣藏的勘探開發(fā)起步較晚,許多頁巖氣勘探和開采關(guān)鍵技術(shù)還不成熟。在非常規(guī)能源中頁巖氣的潛力巨大,很多國(guó)家相關(guān)機(jī)構(gòu)和石油公司開始越來越重視頁巖氣。然而,目前對(duì)某地區(qū)頁巖氣地質(zhì)儲(chǔ)量的計(jì)算和頁巖儲(chǔ)層的評(píng)價(jià)仍然是需要解決的問題。頁巖氣的儲(chǔ)集層孔隙結(jié)構(gòu)對(duì)頁巖氣的儲(chǔ)集能力有影響,同時(shí)頁巖氣儲(chǔ)層孔隙結(jié)構(gòu)對(duì)頁巖氣井的產(chǎn)量和最終采收率也有影響。經(jīng)大量的研究發(fā)現(xiàn),有大半的頁巖氣存儲(chǔ)在孔隙中,巖石孔隙是頁巖氣主要賦存的空間。對(duì)頁巖氣儲(chǔ)層的評(píng)價(jià)就是對(duì)頁巖氣的孔隙結(jié)構(gòu)研究,頁巖孔隙結(jié)構(gòu)研究對(duì)頁巖氣勘探開發(fā)具有重要的指導(dǎo)性意義。論文將通過頁巖氣儲(chǔ)層孔隙結(jié)構(gòu)分析,利用頁巖氣測(cè)井評(píng)價(jià)方法,以評(píng)價(jià)儲(chǔ)層、計(jì)算頁巖地質(zhì)儲(chǔ)量作為主要研究?jī)?nèi)容,最終達(dá)到對(duì)頁巖氣的合理分布預(yù)測(cè)目的。本論文對(duì)頁巖有效儲(chǔ)層識(shí)別和某區(qū)青一段泥頁巖有利區(qū)地質(zhì)資源量的計(jì)算進(jìn)行了具體應(yīng)用。并且利用了頁巖氣資源量計(jì)算里最普遍、最準(zhǔn)確的體積法計(jì)算。最終結(jié)果表明,獲得頁巖有效儲(chǔ)層可以應(yīng)用測(cè)井定量評(píng)價(jià)法。同時(shí),可以通過頁巖氣有利區(qū)各參數(shù)優(yōu)選,并結(jié)合頁巖氣資源體積法基本原理,確定相關(guān)參數(shù),最終計(jì)算得到該地區(qū)青一段泥頁巖頁巖氣的含氣量。
[Abstract]:The increasing increase in world energy consumption and the increasingly prominent contradiction between supply and demand are obvious. Since the 1990s, people have gradually attached importance to unconventional natural resources. The exploration and development of unconventional oil and gas resources have been mentioned in the important deliberations of many countries. Among the important supplementary energy sources in the 21st century, unconventional oil and gas resources have been included in the list. The United States was the first country to develop shale gas, and has now achieved success in the United States. China is the country with the most abundant shale gas resources in the world, but the exploration and development of shale gas reservoirs in China started relatively late. Many key technologies for shale gas exploration and exploitation are not yet mature. The potential of shale gas in unconventional energy sources is so great that many national institutions and oil companies are beginning to pay more and more attention to shale gas. However, At present, the calculation of shale gas geological reserves and the evaluation of shale reservoirs are still problems to be solved. The pore structure of shale gas reservoir has an effect on the reservoir capacity of shale gas. At the same time, the pore structure of shale gas reservoir also has influence on the production and final recovery of shale gas wells. After a lot of research, it is found that most of the shale gas is stored in the pores. Rock pore is the main space of shale gas. The evaluation of shale gas reservoir is to study the pore structure of shale gas. The study of shale pore structure has important guiding significance for shale gas exploration and development. This paper will analyze the pore structure of shale gas reservoir and use shale gas logging evaluation method to evaluate the reservoir. The calculation of shale geological reserves as the main research content, Finally, the reasonable distribution of shale gas is predicted. In this paper, the effective reservoir identification of shale and the calculation of geological resources in the favorable area of the first member of shale in a certain area have been applied concretely, and the calculation of shale gas resources is the most common in the calculation. The most accurate volume method is calculated. The final result shows that the logging quantitative evaluation method can be used to obtain the effective shale reservoir. At the same time, the parameters of shale gas favorable zone can be optimized, and the basic principle of shale gas volume method can be combined with the basic principle of shale gas resource volume method. The relevant parameters are determined and the gas content of shale gas in the first member of Qinghai is calculated.
