根据烃源岩热解地球化学分析成果,应用所测岩样中有机碳(TOC)、吸附烃(S_1)、干酪根热解烃(S_2)含量及氢指数I_H (S_2/有机碳),对绥滨坳陷滨参1井和绥D_1井下白垩统煤系地层中的煤系泥岩、碳质泥岩和煤岩从有机质丰度、有机质类型和成熟度三个方面进行了烃源岩分析评价.这三种岩石样品中各项生油岩指标绝大多数都达到了中-好烃源岩评价标准.绥滨坳陷下白垩统城子河组和穆棱组为两套具生烃潜力的煤系烃源岩.

According to the thermal decomposition analysis achievements of the mudstone, carbonaceous mudstone and coal samples gathered from the Lower Cretaceous coal measure strata of Well Bincan 1 and Well Sui D_1 in the Suibin depression, this paper analyses the organic matter abundance, type and maturation with TOC, S_1 (the absorption hydrocarbon), S_2 (the hydrocarbon of kerogen decomposition) and IH (Hydrogen Index, S_2/TOC). An absolute majority of samples have the ranges of organic richness from medium level to high level. The result of above analysis indicates that the Lower Cretaceous coal measure strata of Suibin depression, including the Lower Cretaceous Chengzihe Formation and Muleng Formation are the coal measure source rocks with a high hydrocarbon generating potential.
