【摘要】：本論文以白音查干凹陷達爾其地區(qū)騰格爾組為研究對象,綜合運用測井、錄井、巖心、薄片、分析化驗等資料,系統(tǒng)的開展了儲層特征方面的研究,主要取得以下幾點認識:騰格爾組巖石類型以巖屑石英砂巖與巖屑砂巖為主。西南部D34井區(qū)與東南部D14井區(qū)具有明顯的相似性,都是以高石英、高巖屑含量為特征;而北部D1井區(qū)總體上以高石英含量為特征。騰格爾組儲層砂巖巖屑類型按含量依次為變質(zhì)巖巖屑、沉積巖巖屑、巖漿巖巖屑;西南部D34井區(qū)巖屑類型為沉積巖巖屑;東南部D14井區(qū)巖屑類型為變質(zhì)巖巖屑;北部D1井區(qū)巖屑類型為變質(zhì)巖與沉積巖巖屑。騰格爾組儲層成巖作用階段為中成巖A期。成巖作用類型多樣,發(fā)育壓實、膠結(jié)、交代和溶解作用。整體壓實強度為中-較強壓實;壓實強度與深度、巖石粒度有關(guān),深度越大,粒度越細,壓實程度越強;膠結(jié)程度為弱膠結(jié)。研究區(qū)儲層孔隙類型主要原生粒間孔隙、粒間溶蝕孔隙以及裂縫三種類型。毛管壓力曲線分為三種類型,整體以Ⅱ類居多。反映整個凹陷儲層以中孔喉類型為主,儲集性能中等。依據(jù)巖性、成巖特征、孔隙類型、物性、孔喉結(jié)構(gòu)參數(shù)以及孔喉分布特征等建立儲層分類評價標準,將研究區(qū)儲層劃分為3種類型。對重點井與重點區(qū)域展開了儲層評價,得出騰上段主要為Ⅱ類儲層;騰下段以Ⅲ類儲層為主。
[Abstract]:In this paper, the Tengger formation in Darqi area of Baiyinchagan depression is taken as the research object, and the reservoir characteristics are systematically studied by using logging, logging, core, thin slice, analysis and laboratory data, etc.The main rock types of Tengger formation are lithic quartz sandstone and lithic sandstone.The southwest D34 well area is similar to the southeast D14 well area, which is characterized by high quartz and high cuttings content, while the north D1 well area is characterized by high quartz content.The types of sandstone lithology in Tengger formation are metamorphic, sedimentary and magmatic according to their content, depositional lithology in D34 well in southwest, metamorphic lithology in southeastern D14 well, metamorphic lithology and metamorphic lithology in southeastern D14 well area.The diagenesis stage of Tengger formation is middle diagenesis A.Various diagenesis types, development compaction, cementation, metasomatism and dissolution.The overall compaction strength is medium-strong compaction; the compaction strength is related to depth and rock granularity. The greater the depth, the finer the granularity, the stronger the compaction degree, and the stronger the cementation degree is.The reservoir pore types in the study area are mainly primary intergranular pore, intergranular dissolution pore and fracture.Capillary pressure curve can be divided into three types.It reflects that the reservoir in the whole sag is dominated by the type of mesoporous throat, and the reservoir performance is medium.According to lithology, diagenetic characteristics, pore types, physical properties, pore throat structure parameters and pore throat distribution characteristics, the reservoir classification and evaluation criteria are established, and the reservoirs in the study area are divided into three types.The reservoir evaluation of key wells and regions shows that the Teng upper member is mainly of class 鈪，
