【摘要】：非常規(guī)油氣資源在世界能源結(jié)構(gòu)中扮演著日益重要的角色,被視為一種由常規(guī)能源向綠色能源轉(zhuǎn)變過程中的過渡能源。目前致密氣和致密油已成為勘探開發(fā)重點(diǎn)。在大慶外圍發(fā)育的諸多中、新生代含油氣盆地中,延吉盆地由于其所處的特殊的構(gòu)造位置和具有較大油氣資源遠(yuǎn)景,本文以致密油氣為重點(diǎn),對(duì)吉林省延吉盆地致密油氣的資源潛力做較深入探析。延吉盆地的油氣地質(zhì)研究對(duì)當(dāng)?shù)鼐哂薪?jīng)濟(jì)意義。針對(duì)延吉盆地致密油氣資源的評(píng)價(jià),可以落實(shí)該區(qū)致密油氣前景,指導(dǎo)下一步油氣勘探方向。低勘探程度盆地致密油氣資源評(píng)價(jià)是一個(gè)難題,國(guó)內(nèi)外尚無明確方法規(guī)范。通過本次工作預(yù)期設(shè)計(jì)出合理有效的方法手段,對(duì)其它地區(qū)具參考價(jià)值,能夠?yàn)檠蛹璧氐母钊胙芯?提供一定的幫助。以大地構(gòu)造學(xué)、油氣地球化學(xué)、儲(chǔ)層地質(zhì)學(xué)、沉積學(xué)、石油地質(zhì)學(xué)等基礎(chǔ)理論為指導(dǎo),綜合利用野外露頭、測(cè)井、錄井、巖心、地震等資料,對(duì)延吉盆地的生儲(chǔ)蓋特征進(jìn)行詳細(xì)研究,確定油氣成藏的主控因素,綜合利用生烴法、資源豐度和體積法三種方法計(jì)算得到目標(biāo)有利區(qū)致密油氣資源量。結(jié)果表明,延吉盆地主要烴源巖層位為大砬子組大一段、銅佛寺組銅三段、銅二段,有機(jī)質(zhì)類型以ⅡA~ⅡB型為主,含少量Ⅲ型,大部分地區(qū)已進(jìn)入生油門限,已基本處于成熟階段;主要儲(chǔ)層是龍井組、大砬子組和銅佛寺組內(nèi)砂巖,以粉砂巖、細(xì)砂巖和中砂巖為主,儲(chǔ)層物性總體以中孔低滲的砂巖孔隙型儲(chǔ)層為主;致密油的保存受到蓋層、構(gòu)造活動(dòng)、地層傾角以及水動(dòng)條件影響;綜合分析致密油氣成藏規(guī)律,針對(duì)“有生有儲(chǔ)無運(yùn)有�！彼脑瓌t條件篩選出有利區(qū),最終計(jì)算延吉盆地4號(hào)、5號(hào)有利區(qū)油資源量為30×104t,氣資源量為2.3×108m3。
[Abstract]:Unconventional oil and gas resources play an increasingly important role in the world's energy structure. It is regarded as a transition energy from conventional energy to green energy. At present, dense gas and tight oil have become the focus of exploration and development. In many Mesozoic and Cenozoic petroliferous basins developed in the periphery of Daqing, Due to its special structural position and great oil and gas potential, the Yanji basin is focused on dense oil and gas. The resource potential of dense oil and gas in Yanji Basin of Jilin Province is deeply analyzed. The study of oil and gas geology in Yanji Basin is of economic significance to the local area. The evaluation of dense oil and gas resources in Yanji Basin can realize the prospect of dense oil and gas in this area. The evaluation of dense oil and gas resources in low exploration degree basins is a difficult problem, and there is no clear method and standard at home and abroad. Through this work, a reasonable and effective method is designed, which has reference value to other regions. It can provide some help for the further study of Yanji basin. Guided by the basic theories of geotectonics, oil and gas geochemistry, reservoir geology, sedimentology, petroleum geology and so on, the comprehensive use of outcrop, logging, logging, etc. Based on the core and seismic data, the characteristics of reservoir, reservoir and cap in Yanji Basin are studied in detail to determine the main controlling factors of oil and gas accumulation, and to make comprehensive use of hydrocarbon generation method. The results show that the main source rocks in Yanji Basin are the first member of Dali formation, the third member of Tongfosi formation, the second member of copper formation, the other is the third member of Tongfosi formation, the third member of Tongfosi formation, the third member of Tongfosi formation, and the third member of Tongfosi formation. The main types of organic matter are type 鈪，
