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
利用由作者提出的井內流動和傳熱的三維數值模型計算所得的大量數據,文章對影響井內溫度的諸多因素進行了較系統的敏感性分析,研究表明:
鉆井液和
地層等的熱物理參數以及

鉆井液的熱物理參數值,考慮溫度壓力對熱物理參數的影響,準確測量
鉆井液的入口溫度、排量等參數值,對于井內溫度的準確模擬至關重要。
Parameters can be interpreted through the method used in straight wells. after logging curves in horizontal wells are revised to true vertical depth, oil - bearing formation is evaluated through the comparison of wells combined with geological information. logging while drilling have great difference with ordinary cable logging especially in deviated holes and horizontal wells. comparison of cable logging and lwd carried out in different time indicates characters of mud invasion
