摘要
在分析了套管可通过的最大井眼曲率影响因素的基础上，参考了国内φ１３９７ｍｍ套管弯曲试验数据和胜利、大港油田的现场经验，提出了一种套管可通过的最大井眼曲率的确定方法，并给出了计算公式和算例。算例表明，该公式比ＡＰＩ和ＩＡＤＣ推荐的公式更接近实际。
Based on analyzing the factors related with the maximum hole curvature that the casing can be run through , and using the data of casing bend testing at home and the site experience of Shengli Oilfield and Dagang Oilfield,this paper raised a determining method that the casing can be run through maximum hole curvature and gave the calculating formula and some examples.The examples said the formula is closer to reality than that given by API and IADC,and said also the casing bend testing need do further.
