A Method of Calculating Rheology of Cement Slurry Affected by Circulation Temperature
摘要
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 ofborehole fluids is more remarkably affected by temperature.Based on the analyses ofHTHP rheological data obtained,a model for calculating the changing pattern ofrheological 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.关键词
