下古生界碳酸盐岩生烃条件及二次生烃潜力评价——以临清地区TG5井为例

Evaluation for Hydrocarbon Generating Conditions and Second Potential of Lower Paleozoic Era Carbonats Source Rock

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 achievements 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
