【摘要】：松遼盆地油頁(yè)巖資源極為豐富,本次研究利用位于松遼盆地北部的全取芯井,對(duì)油頁(yè)巖有機(jī)質(zhì)峰度、有機(jī)質(zhì)類型、有機(jī)質(zhì)成熟度和工業(yè)品質(zhì)進(jìn)行了研究,并分析了研究區(qū)油頁(yè)巖的沉積環(huán)境。研究結(jié)果表明:松遼盆地北部青山口組一段共發(fā)育8層油頁(yè)巖,平均含油率為5.26%,最高含油率可達(dá)12.65%,油頁(yè)巖有機(jī)質(zhì)峰度較高,有機(jī)質(zhì)類型主要為Ⅰ型和Ⅱ型,處于未成熟-低成熟的熱演化階段。工業(yè)品質(zhì)研究表明,油頁(yè)巖主要為中等偏高品質(zhì)、高灰分、較高揮發(fā)分、高發(fā)熱量、低密度和特低硫型。通過(guò)對(duì)沉積環(huán)境的分析,研究區(qū)油頁(yè)巖主要形成于半深湖-深湖,其中品質(zhì)較好的油頁(yè)巖層發(fā)育在高水位體系域中,因?yàn)檩^深的湖泊水體可能有助于油頁(yè)巖中有機(jī)質(zhì)的保存。
[Abstract]:The oil shale resources in Songliao Basin are extremely rich. In this study, the kurtosis, type, maturity and industrial quality of organic matter in oil shale were studied by using the core well located in the northern part of Songliao Basin. The sedimentary environment of oil shale in the study area was analyzed. The results show that there are 8 layers of oil shale in the first member of Qingshankou formation in the northern part of Songliao Basin. The average oil content is 5.26 and the highest oil content can reach 12.65. The kurtosis of organic matter in oil shale is relatively high, and the types of organic matter are mainly type 鈪，
