多点测斜仪自动记录深度的方法

A method of recording depth automatically for the deviation instrument

传统的多点测斜仪测量时,测试人员必须在井口记录起钻井下钻具的深度所对应的时间,最后合成井斜与深度的变化关系。文章介绍了一种新方法,通过与测斜仪一起测得的压力数据特征来实现自动记录深度的目的。

When the deviation instrument runs,it only can get the relation of deviation and time.For getting the relation of deviation and depth,people must record the time and depth when up and down the drilling strings.Now we get a new method to solve this problem by adding the pressure gauge in the deviation instrument.Analyzing the character of pressure plat when up and down the drilling strings,then checking the drilling strings form,we achieve the relation of deviation and depth.So we realize the function to record the depth automatically.
