采用黄金管限定体系,对塔里木盆地牙哈、哈得原油样品进行了热模拟实验,研究了原油样品热裂解生成气态烃的产率特征及其动力学参数。结果表明,牙哈、哈得原油样品裂解具有高的C_(1-5)产率(738.87 ml/g、598.98 ml/ g)和C_(2-5)产率(256.85 ml/g、188.63 ml/g)。牙哈、哈得原油样品裂解成气动力学参数存在差异:牙哈原油样品裂解气甲烷、乙烷、丙烷生成的活化能范围分别为(66~83) x4. 186 kJ/mol、(59~72) x4. 186 kJ/mol、(59~65) x4. 186 kJ/mol,频率因子各为2.07×10~(16)_s~(-1)、1.0x10~(14)_s~(-1)、1.0x10~(14)_s~(-1);哈得原油样品裂解气甲烷、乙烷、丙烷生成的活化能范围分别为(63~84) x4.186 kJ/mol、(57-63) x4.186 kJ/mol、(58 -70) x4. 186 kJ/mol,频率因子各为1.42×10~(16)。以塔东地区满东1气藏为例进行了动力学模拟应用研究,认为原油的大量裂解为满东1气藏提供了主要气源。 |

The thermal simulation experiment of Yaha and Hade crude oil samples in Tarim Basin was carried out, by using the gold tube confined system. The yield characteristics and kinetic parameters of cracking gases from Yaha and Hade oil samples were studied. The results demonstrate that the Yaha and Hade oil samples have high total gas yields (738.87 ml/g, 598.98 ml/g) and C_(2-5) yields (256.85 ml/g, 188.63 ml/g). Differences are existed in the kinetic parameters of cracking gases in the Yaha and Hade oils. The activation energy distributions of methane, ethane and propane generated from the Yaha oil sample are in the range of (66~83) x 4. 186kJ/mol, (59~72)x4.186kJ/ mol, and (59~65) x4. 186kJ/mol. Their frequency factors from the Yaha oil sample are 2.07x10~(16) s~(-1), 1.0 x 10~(14) s~(-1), and 1.0 x 10~(14)s~(-1), respectively. The activation energy distributions of methane, ethane and propane from the Hade oil sample are in the range of (63~84) x4. 186 kJ/mol, (57~63) x4. 186 kJ/mol, and (58 -70) x 4. 186 kJ/mol. Their frequency factors from the Hade oil sample are 1.42 x 10~(16) s~(-1), 1.0 x 10~(14) s~(-1),and 1. 0 x 10~(14) s~(-1), respectively. The Mandong 1 gas pool in the eastern Tarim Basin was taken as an example and its kinetic modeling of gas generation was studied. It is suggested that gas source of the Mandong 1 gas pool was resulted from a large number of crude oil cracking. |
