    摘要:

    针对原油集输管网的流量计测量数值偏差大, 模拟仿真软件人工校正繁琐、自适应差的问题, 提出一种自适应时空图卷积神经网络的产量计算方法, 实现原油集输管网产量的模拟计算. 以潜油电泵井为节点, 输油管道为边构建管网拓扑图. 使用图卷积神经网络提取井分布空间信息, 时间卷积神经网络获取产量数据的时间序列特征, 计算得到准确的产量模拟计算结果. 在某油田原油集输管网系统上进行了实验验证, 结果表明本文方法能够准确对管网系统内各电泵井的产量进行计算, 与其他基准网络模型相比, 各项误差指标均有下降, 平均绝对误差降至0.87, 平均绝对百分比误差降至4.45%, 均方误差降至0.84, 证明了提出方法的有效性和准确性.

    Abstract:

    Flowmeter measurement values have a large deviation in crude oil gathering and transmission pipeline network, and the manual correction of simulation software is cumbersome with poor adaptive. To solve these problems, this study proposes an adaptive spatio-temporal graphic convolutional neural network production calculation method to realize the simulation calculation of crude oil gathering and transmission pipeline network production. The topology of the pipeline network is constructed with the submerged oil electric pump wells as nodes and the oil pipelines as edges. The study utilizes the graph convolutional neural network to extract the spatial information of well distribution and the temporal convolutional neural network to obtain the time series characteristics of the production data, so as to calculate the accurate production simulation results. The experimental validation is carried out on the crude oil gathering and transmission pipeline network system of an oil field. The results show that the proposed method can accurately calculate the production of each electric pump well in the pipeline network system. Compared with other baseline network models, the error indexes are reduced: the average absolute error is reduced to 0.87; the average absolute percentage error is reduced to 4.45%; the mean square error is reduced to 0.84, which proves the validity and accuracy of the proposed method.
