钻井液流变模型的优选

The Optimization of Rheological Model

选择合适的工程浆液流变模型是现场生产中很重要的技术问题。基于最小二乘法原理利用Visual C＋＋高级语言编制程序对试验数据进行拟合，可求得实测浆液的常用流变参数值，绘制各常用流变模式与实际流型的曲线，从而优选出最合适的流变模式。

It is very important that choosing the appropriate project＇s rheological model on the spot. Based on the principle of least squares and Advanced Visual C＋＋ programming language, the experimental data can be fitted and the standard rheologica parameters of test data can be educed, rendering curves of each rheological model and measured fluid, so the most suitable rheological model can be optimized.
