摘要： 通过研究BP神经网络算法和混合原油凝点测量数据，用BP神经网络建立一种混合原油的凝点预测模型。引入具有高度非线性预测能力的误差反向传播的人工神经网络方法，以单组分原油凝点及其配比作为神经网络的输入向量，以混合原油凝点为输出向量，研究混合原油凝点与单组分原油凝点及配比之间的相关性。预测结果表明，混合原油凝点预测值的最大绝对偏差为0.128℃，平均绝对偏差为0.022℃，BP神经网络的凝点预测结果准确性明显优于其它混合原油凝点预测模型。

Abstract:

The BP neura1 network and the tested gel points of the blend crude oil were studied. A prediction model based on the BP neura1 network was established to calculate the gel point of the blend crude oil. The back-propagation artificial neural network has the satisfactory nonlinear prediction ability. The gel points of the component crude oil and their proportions were taken as the input vector and the gel points of the blend crude oil as the output one. The relationship between the gel points of the blend crude oil and the component crude oil was researched. The results show that the gel point prediction model based on the BP neura1 network is better than other gel point prediction models. The maximum average deviation of the predicted gel point is only 0.128 °C and the average absolute deviation is 0.022 °C. 
