Rheological Parameter Calibration of Online Drilling Fluid Property Monitoring System
摘要
Abstract
In drilling operations,accurate and fast measurement of drilling fluid rheology is essential for safe and efficient drilling.Pipe flow method can monitor the rheological properties of drilling fluids in a real time manner,wall slip phenomenon can seriously affect the accuracy of the measurement though.To deal with this problem,the relationship between pipe flow and the effects of wall slip is discussed in depth,and a rheology calibration method based on pipe flow method is presented.In this method,the measurement is conducted using pipe flow method,the slip velocity is obtained using Mooney and regularization method on the data acquired,time is windowed to form ordered data,and a modal named WOA-SVR for predicting slip velocity is constructed.The shear rate on the wall and the generalized flow index are then corrected using the slip velocity obtained.Using this method,the rheological properties of a drilling fluid are calibrated and the accuracy of the output rheological properties is increased by 75.01%.The results of this study have been used in Tarim,Xinjiang and Huabei oilfields,the instrument measurement results are highly consistent with the results obtained by analyzing the manual samples,indicating that this method is both effective and practical.This method can provide reliable data support for the comprehensive evaluation of the rheological parameters for the online monitoring system of drilling fluid properties,and is of great significance to the improvement of drilling efficiency and safety.关键词
