摘要
本文从碳酸盐-水-二氧化碳平衡关系出发,建立了应用罗兹纳稳定指数(RYZ-NAR(Stability index)计算油田水pH_?的方法、以及用它预测和判别油田水碳酸盐结垢趋势。该法和其它方法相比,所得结果较好。
The paper presents a method for calculating pH of waters from oil reser-voirs. It is deduced from RYZNAR stability index with carbonate-H_2O-CO_2equilibrium relation. This method may be used to fore cast and distinguish the ten-dency of carbonate precipitation in oil reservoir waters and get a better effectin comparison with other methods.
