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。
According to organic matter abundance, kerogen type and evolution characteristics of organic matter and combined with the past two, the Chaganuoer fault depression shows the potential of hydrocarbon accumulation in the exploration process. Based on the analysis of all single- Dimensional seismic interpretation of source rock evaluation and resource potential analysis. The results show that the source rocks are concentrated in the Damoguaihe and Nantun formations, and the type of organic matter is mainly Type II and Type III kerogen. The current source rock thickness of the Nantun-Damoguaihe Formation is generally 350 ~ 730m, of which high-quality source rocks are mainly concentrated in the Nantun group.
