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 C₁-C₄ gas can be easily generated from condensate. As a result, the quantity of gas generated from condensate and C₁/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 C₁/C_2-4, nonhydrocarbon/alkane of natural gas increaese with the increase of migration distance, and that the existance of SiO₂ media has promoting effect on cracking of the condensate.
