【摘要】：柴達木盆地具有豐富的油氣資源,柴北緣、柴西、柴東三湖地區(qū)分別以侏羅系、古近系、新近系和第四系為主要勘探目的層。隨著準(zhǔn)噶爾盆地石炭系研究的進展和鉆探的成功,石炭系已經(jīng)成為中國西部地區(qū)重要的勘探層系。柴達木盆地的石炭系廣泛發(fā)育,厚度較大,為一套碎屑巖與碳酸鹽巖混合巖系,地質(zhì)調(diào)查表明,石炭系為柴達木盆地一套潛在烴源巖。德令哈地區(qū)是柴達木盆地石炭系出露最多、地層層序最完整的地區(qū)。通過對德令哈及柴東地區(qū)MT勘探資料的處理解釋和綜合研究,對石炭系分布進行了深入研究,認為石炭系分布范圍廣、厚度大、構(gòu)造穩(wěn)定,其中歐龍布魯克凸起油氣成藏條件有利,是勘探的有利目標(biāo)。
[Abstract]:The Qaidam Basin is rich in oil and gas resources. Jurassic Paleogene Neogene and Quaternary are the main exploration targets in the northern margin of Qaidam Basin western Qaixi and Sanhu area of Qaidong. With the development of Carboniferous research and the success of drilling in Junggar Basin, Carboniferous has become an important exploration strata in western China. The Carboniferous in Qaidam Basin is a series of clastic rocks and carbonate rocks. The geological investigation shows that Carboniferous is a set of potential source rocks in Qaidam Basin. Delingha area is the area with the most outcrop of Carboniferous system and the most complete stratigraphic sequence in Qaidam Basin. The distribution of Carboniferous in Delingha and Chaidong area is studied deeply through the processing interpretation and comprehensive study of MT exploration data. It is considered that Carboniferous distribution has a wide range, a large thickness and a stable structure. The Oulunbrook uplift is favorable for oil and gas accumulation and is a favorable target for exploration.
