摘要

摘要: 在注水泥过程中，钻井液与水泥浆在不同井深位置所受到的作用温度是不同的。在深井情况下，高温对流体流变性能的影响更加明显。通过对高温高压流体流变实验数据的分析处理，建立了通过测定2个温度下流体流变性能数据，从而计算不同温度下流体流变性能变化规律（剪切应力）的计算模型与方法，并提出了针对深井注水泥具体分段考虑温度对流变性影响计算的方法。通过对流变实验测试数据的计算误差分析，说明该计算方法的实际误差是可接受的，计算方法是可行的。

Abstract: In well cementing operations, cement slurriesflowing along the hole and the drilling fluid in place are experiencing different temperatures at different well depths. In deep wells, rheology of borehole fluids is more remarkably affected by temperature. Based on the analyses of HTHP rheological data obtained, a model for calculating the changing pattern of rheological data at different temperatures was developed. Raw data for the model can be acquired by measuring the rheological data of fluids at different temperatures. A method of calculating the effects of temperature on rheology in deep well cementing was developed based on the model. Error analysis of rheological data acquired from rheology measurement indicates that errors associated with the calculation method are acceptable, and the calculation method is hence applicable.
