摘　　要：在半封闭管临界性质测定装置上实测塔里木原油 2 4个宽、窄馏分油的临界温度和临界压力。在实测数据基础上 ,采用逐步回归法预测临界性质 ,临界温度和临界压力的平均绝对偏差分别为 2 .6 0～ 3 .5 0K和 0 .0 42～0 .0 43MPa ,平均相对偏差分别为 0 .40 %～ 0 .5 0 %和 1.6 1%～ 1.89% 。Critical temperatures and pressures of the 24 wide and narrow fractions from Talimu crude were determined with the semi sealed tube appratus and correlated with gradual regression. The average absolute and relative errors of critical temperature and pressure are 2.6 3.5 K,0.042 0.043 MPa and 0.4% 0.5% and 1.6% 1.9% ,respectively,basically meeting the engineering requirements.
