摘要
Abstract
The calculation of equivalent circulation density(ECD)of drilling fluids is very cumbersome and time-consuming,and the pattern of sensitivity of the ECD has not been quite understood yet.To solve this problem,1928 data from the Block Keshen were acquired and analyzed using the ProHydraulic software to calculate the theoretical ECD.Based on the calculation some characteristic parameters were determined.Key factors affecting the sensitivity of the ECDs of a drilling fluid,such as mud properties,drilling parameters and sizes of the annular spaces are analyzed using interpretable machine learning technology.Using linear regression,an empirical equation for calculating the ECDs of drilling fluids in the Block Keshen,which covers 12 main characteristic parameters,is constructed.ECD calculation with the model shows that the model gives results that fit the practical values with excellence.The coefficient of determination of the testing set is 0.963,and the average absolute error is only 0.04,indicating that this empirical equation is simple and efficient in ECD calculation in practical engineering application.关键词
