【摘要】 查干诺尔断陷在勘探过程中显示出较好的油气成藏潜力,通过对断陷内所有单井有机地化指标进行分析,根据有机质丰度、干酪根类型、有机质演化特征并结合以往二维地震解释成果进行烃源岩评价和资源潜力分析。分析结果表明:烃源岩集中分布于大磨拐河组与南屯组,有机质类型以Ⅱ型、Ⅲ型干酪根为主,南屯组-大磨拐河组现今的烃源岩厚度一般为350~730m,其中优质烃源岩主要集中在南屯组。更多还原

【Abstract】 The rift Chagannuoer in the exploration process showed good potential for hydrocarbon accumulation. Based on the analysis of single well organic geochemical indicators,according to the abundance of organic matter,the type of kerogen,organic matter evolution combined with the previous two-dimensional seismic interpretation evaluation of source rocks and potentiality of resources are analyzed. The analysis results show that: source rocks are concentrated in the Damoguaihe Formation and Nantun Formation,the type of organic matter are main of type II and type III kerogen,the thickness of the source rocks in Nantun and Damoguaihe Formation is 350m in to 730m,The best source rocks are in the Nantun Formation.更多还原
