Для количественного анализа использованы метод частичных наименьших квадратов (PLS) и сверточные нейронные сети (CNN), основанные на наборе данных спектров УФ-пропускания. Коэффициент корреляции между содержанием нефти и мутностью сточных вод нефтепромысла 0.924 свидетельствует о линейной зависимости между содержанием нефти и мутностью. Мутность добавляется в набор данных для исследования ее влияния на точность прогноза. Показано, что точность моделей, построенных по коэффициенту пропускания и мутности, выше, чем у моделей, построенных только по коэффициенту пропускания, что подтверждается как для PLS, так и для CNN. При одинаковом составе набора данных модели PLS и CNN почти точны, но в целом CNN работает немного лучше. Положено начало прогнозированию нефтесодержания в сточных водах нефтепромыслов на основе УФспектрофотометрии и дальнейшему внедрению оперативного детектирования.</p></abstract><trans-abstract xml:lang="en"><p>Oil content plays an important role in oilfield wastewater treatment. To investigate the forecast of oil content by UV spectrophotometry, samples of oilfield wastewater are collected, and their UV transmittance and turbidity are measured. Partial least squares (PLS) and convolutional neural networks (CNN) based on a dataset of UV transmittance spectra are used for quantitative analysis in this work. The correlation coefficient between the oil content and turbidity of oilfield wastewater is 0.924, which shows a high positive linear correlation between the oil content and turbidity. Turbidity is added to the dataset to investigate its influence on the accuracy of prediction. The results show that the accuracy of models built by transmittance and turbidity is higher than that of models built by transmittance only, which is confirmed for both PLS and CNN. With the same dataset composition, the PLS and CNN models are nearly accurate, but the CNN performs slightly better overall. This work laid the foundation for the prediction of oil content in oilfield wastewater based on UV spectrophotometry and the further implementation of online detection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спектр пропускания УФ-излучения</kwd><kwd>сверточные нейронные сети</kwd><kwd>сточные воды нефтепромыслов</kwd><kwd>нефтесодержание</kwd><kwd>мутность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>UV transmittance spectrum</kwd><kwd>convolutional neural networks</kwd><kwd>oilfield wastewater</kwd><kwd>oil content</kwd><kwd>turbidity</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Youth Innovative Talents Training Plan of General Undergraduate University in Heilongjiang Province (UNPYSCT-2020148), the Open project of MOE Key Laboratory for Enhanced Oil and Gas Recovery (No. NEPU-EOR-2022-06), and the Postdoctoral support project of Heilongjiang Province (LBH-Q21084).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">F.
