| 摘 要： | 本文针对轮南油田油水系统的特点，对碳酸盐垢、硫酸盐垢的结垢趋势分别进行了理论预测，同时对室内仿真模拟实验结垢样品进行了X射线衍射分析。理论预测结果表明，轮南油田注水系统中可能会形成碳酸盐垢但不会形成硫酸盐垢，理论预测和室内仿真实验结果完全相符。本文为轮南油田注水系统选择合适的阻垢剂提供了依据。

PREDICTION OF SCALINGTENDENCY IN WATER INJECTION SYSTEMSAT LUNNAN OIL FIELDS IN TARIM |
| |
| Abstract: | The tendencies of carbonate and sulfatescaling in different sections of the water injection systems of Lunnan Oil Fields, Tarim,are predicted by using Stiff-Davis' saturation indexes and Skillman's solubility parameteras criteria, respectively, and the tolerancies of the injection water to Ba2+and Sr2+ at different temperatures are calculated. Scaling simulationexperiments are performed on a laboratory installation and the scale layer on the methalsamples is analyzed by X-any diffraction. It is shown that CaCO3 scale willdeposit slightly and must be properly inhibited; no CaSO4 scale will be formed;and (Ba,Sr)SO4 scale appears if Ba2+ and Sr2+ exist ininjection water. |
