在对碳酸盐岩烃源岩成烃条件分析的基础上,研究了沉积环境及岩性对有机质富集程度的影响,并综合烃类包裹体、高压热模拟和盆地模拟分析技术成果,探讨了碳酸盐岩二次生烃潜力。研究认为: TG5 井碳酸盐岩烃源岩具有成熟度高、有机质类型好、有机质丰度偏低的特性;下古生界虽存在二次生烃过程,但生烃潜力较差。

According to hydrocarbon generating conditions analysis of carbonate source rock , the effect of sedimentary environment and rock properties to organic abundance was studied , and it synthesizes achievement s in analysis of hydrocarbon inclusion enclave , heat simulation under high pressure and basin simulation , second hydrocarbon generating Potential of carbonate were also discussed The results revealed that properties of organic matters in Well TG5 are high maturity , good organic type and lower content of organic material
