摘要

凝析油在地层条件下多呈气相存在

运移过程中除可能有一定的相态转化外

也可能受热力作用进一步裂解成气;温度、介质都对凝析油裂解有促进作用。

Abstract

Natural gas generated from differentiation of condensate was studied for understanding its change in quantity

constitute and effected factors by experiments of heating and migration. The results demonstrate that the factor causing the cracking of condensate is mainly temperature

and that C

-C

gas can be easily generated from condensate. As a result

the quantity of gas generated from condensate and C

2-4

nonhydrocarbon/alkane of the gas decreases with the increase of temperature. It is also shown by the study that the value of C

2-4

nonhydrocarbon/alkane of natural gas increaese with the increase of migration distance

and that the existance of SiO

media has promoting effect on cracking of the condensate.
