【摘要】：在稠油的開采、管輸?shù)冗^程中,動力黏度是一個重要的參數(shù),目前對稠油黏度的估計常采用稠油黏度預(yù)測公式進(jìn)行。然而,由于現(xiàn)有的黏度預(yù)測關(guān)系式大多基于區(qū)域性稠油數(shù)據(jù),因此,這些關(guān)系式只對特定區(qū)域特定組分的稠油才有很高的預(yù)測精度。該文采用Hakke RS6000旋轉(zhuǎn)流變儀對中海油采油技術(shù)服務(wù)公司和渤海油田綏中陸地處理終端的共計3種稠油的動力黏度進(jìn)行了測量。稠油30oC的黏度范圍為:241 mPa·s 5 239 mPa·s,測量溫度范圍為:20oC 70oC。將Beal、Hossain等和張春明等共計11個黏度預(yù)測關(guān)系式與該文實驗數(shù)據(jù)進(jìn)行了對比分析。研究表明,在所研究的關(guān)系式中,張春明和Hossain關(guān)系式具有最高的預(yù)測精度,而Alomair關(guān)系式的預(yù)測精度最差。同時,結(jié)合國內(nèi)多個學(xué)者以及該文的實驗數(shù)據(jù),推出了一個新的黏度預(yù)測關(guān)系式。該關(guān)系式是溫度T和50oC的黏度50μ的函數(shù)。它由國內(nèi)多個區(qū)塊的稠油黏度數(shù)據(jù)得來,因此能更好地預(yù)測國內(nèi)稠油的黏度。
[Abstract]:Dynamic viscosity is an important parameter in the process of heavy oil recovery and pipeline transportation. At present heavy oil viscosity prediction formula is often used to estimate the viscosity of heavy oil. However, since most of the existing viscosity prediction formulas are based on regional heavy oil data, these equations only have high prediction accuracy for heavy oil with specific components in a specific area. Hakke RS6000 rotary rheometer is used to measure the dynamic viscosity of three kinds of heavy oil from CNOOC Technical Service Company and Suizhong Terrestrial treatment Terminal of Bohai Oilfield. The viscosity range of heavy oil 30oC is 241 mPa 路s ~ (- 1) 5 239 mPa 路s, and the measured temperature range is: 20oC ~ (70) oC. Beal,Hossain et al. And Zhang Chunming et al were compared with the experimental data in this paper. The results show that the relationship between Zhang Chunming and Hossain has the highest prediction accuracy, while the Alomair equation has the worst prediction accuracy. At the same time, combined with the experimental data of many domestic scholars and this paper, a new viscosity prediction formula is proposed. This equation is a function of viscosity 50 渭 of temperature T and 50oC. It is obtained from viscosity data of heavy oil in many domestic blocks, so it can better predict viscosity of domestic heavy oil.
