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。
Natural gas generated from differentiation of condensate was studied for understand-ing its change in quantity, constitute and effected factors by experiments of heating andmigration. The results demonstrate that the factor causing the cracking of condensate ismainly temperature, and that C_1-C_4 gas can be easily generated from condensate. As a re-sult, the quantity of gas generated from condensate and C_1/C_(2-4), nonhydrocarbon/alkaneof the gas decreases with the increase of temperature. It is also shown by the study that thevalue of C_1/C_(2-4), nonhydrocarbon/alkane of natural gas increaese with the increase of mi-gration distance, and that the existance of SiO_2 media has promoting effect on cracking ofthe condensate.
