borehole fluid
解釋
井內流體-
In this paper, the sensibility analysis of the factors affecting the temperature in well bore is relatively systematically made by using a large number of the data calculated with the borehole flow and heat transfer 3 ? d numerical model proposed by the author. the study shows that the thermophysical parameters of the drilling fluid and formation, etc. and the entrance temperature and circulating capacity, etc. of drilling fluid have a greater influence on the temperature in well bore. therefore, accurately mastering the thermophysical parameter values of penetrated formation and drilling fluid in well bore, considering the influence of the temperature and pressure on thermophysical parameters and accurately measuring such parameters as entrance temperature and discharge capacity of drilling fluid, etc. are of utmost importance for accurately simulating the temperature in well bore
