摘要：2001年，塔里木油田分公司鉆探的英南2井在侏羅系獲得高產(chǎn)工業(yè)氣流，是塔東地區(qū)油氣勘探首次獲得重要發(fā)現(xiàn)，改變了以往人們對塔東地區(qū)的傳統(tǒng)地質(zhì)認(rèn)識，展示了塔東地區(qū)油氣勘探的巨大潛力。塔東地區(qū)勘探的突破取決于人們對該區(qū)石油地質(zhì)認(rèn)識的深化，而勘探的突破進(jìn)一步檢驗了新的認(rèn)識。 通過單井相分析，及對沉積展布特征及其演化的研究。對塔東地區(qū)寒武—奧陶系層序地層特征分析，將層序地層進(jìn)行對比分析，研究了上寒武統(tǒng)-下奧陶統(tǒng)層序地層?xùn)|西部在巖性和厚度上的巨大差異。發(fā)現(xiàn)了生、儲、蓋層縱向上的分布及體系域和層序界面間存在密切關(guān)系，尤其是界面類型和級別是控制寒武-奧陶系碳酸鹽巖儲集層（體）發(fā)育的關(guān)鍵因素之一。塔東地區(qū)寒武紀(jì)—早奧陶世的沉積相演化特征。 關(guān)鍵詞：層序地層；沉積相演化；沉積展布特征
Abstract: In 2011 , Yingnan NO.2 oil well which is drilled by the branch company of Tarim oilfield got high yield industrial airflow in Jurassic . It is the first important discovery of oil and gas exploration in the eastern Tarim Basin which changes people's traditional knowledge of the eastern Tarim Basin and shows the huge potential of the area . The breakthrough of the exploration of eastern Tarim Basin depends on the deeper understanding of the area by people . In addition , the huge breakthrough tests the new knowledge to go a step further . Experts analyzed the special oilfield and researched the distribution characteristics and the evolution .Besides , they analyzed the formation characteristics of Cambrian - Ordovician and compared the big difference in rock property and the thickness of sequence stratigraphy of upper Cambrian series with lower Ordovician series. Then , these experts found that there is a closed relation between the distribution and the sequence boundary . Especially,the type and level of Interface is one of the key factors,that controls the development of carbonate rock reservoir ( body ) in Cambrian - Ordovician .Furthermore , they found the evolution features of the de deposition of the Cambrian period and the Early Ordovician period in the eastern Tarim Basin . Key words：The Sequence stratigraphy；Evolution of sedimentary facies；Distribution of deposition characteristics |
