查询词典 spontaneous cracking

Large condensate gas pools are developed in the Ordovician and Carboniferous in the Lunnan low salient. Geochemical study shows that the Ro of gas condensate in these gas pools is in the range of 0.8% 1.0%(far below the threshold of R o＝1.3％ for thermal cracking), and the condensate gas is overmature dry gas (with R o＞2.0%). Moreover, the crude oil and dry gas in the study area were charged in different stages, indicating that the genesis of the condensate gas was not thermal cracking.

轮南低凸起奥陶系及石炭系发育大规模的凝析气藏，地球化学的研究结果表明，这些凝析气藏中凝析油 Rc 在0.8%~1.0％（远低于热裂解成因 R o＝1.3％的门限），凝析气为过成熟干气（回归 R o＞2.0％）；同时，区内原油与干气的充注期相异，表明轮南地区的凝析气藏并非热裂解成因的产物。
