【摘要】：通化盆地是松遼盆地東部外圍的油氣遠(yuǎn)景區(qū)之一,烴源巖發(fā)育特征和生烴潛力等問(wèn)題未知,制約著盆地基礎(chǔ)油氣資源研究和后續(xù)油氣資源勘探部署工作。為揭示通化盆地下白堊統(tǒng)烴源巖生烴潛力和頁(yè)巖油氣的賦存狀態(tài),在盆地內(nèi)部署通地1井,對(duì)巖芯樣品進(jìn)行系統(tǒng)取樣,完成了暗色泥巖有機(jī)質(zhì)豐度、類型和成熟度的測(cè)試工作。實(shí)驗(yàn)結(jié)果表明,通化盆地下白堊統(tǒng)亨通山組暗色泥巖有機(jī)質(zhì)豐度較高,有機(jī)質(zhì)類型以Ⅰ-Ⅱ1型為主,局部含有Ⅲ型,鏡質(zhì)組反射率分布范圍為0.972%~1.127%,已進(jìn)入大量生烴的成熟階段;下樺皮甸子組暗色泥巖有機(jī)質(zhì)豐度較高,有機(jī)質(zhì)類型以Ⅰ型為主,局部含有Ⅱ和Ⅲ型,鏡質(zhì)組反射率在0.986%~1.399%之間,已進(jìn)入大量生烴的成熟階段。其地球化學(xué)特征和世界上許多頁(yè)巖油氣田的烴源巖有相似之處,綜合研究表明通化盆地下白堊統(tǒng)具有較好的常規(guī)油氣和頁(yè)巖氣生成潛力。
[Abstract]:Tonghua Basin is one of the oil and gas scenic spots in the eastern part of Songliao Basin. The source rock development characteristics and hydrocarbon generation potential are unknown, which restricts the basic oil and gas resources research and the subsequent exploration and deployment of oil and gas resources in the basin. In order to reveal the hydrocarbon generation potential of lower Cretaceous source rocks and the occurrence state of shale oil and gas in Tonghua Basin, Tongdi well 1 was deployed in the basin. The core samples were systematically sampled, and the organic matter abundance, type and maturity of dark mudstone were tested. The experimental results show that the dark mudstone of the Lower Cretaceous in Tonghua Basin has high organic matter abundance, mainly type 鈪，
