Length Of Drill Collar Formula. the following formula is used to determine required drill collar weight to obtain a desired weight on bit for a vertical well. 6.1 drill collar length 205 6.2 bending stress ratio (bsr) 207 6.3 pipe wall thickness 207 6.4 resonant frequency 209 6.5 tensions. to calculate the minimum length of drill collars, you need to consider several factors such as the well depth, the required weight on bit (wob), and. the weight of a drill collar is determined by its length, outer diameter, and wall thickness. a commonly referenced formula for determining the length of drill collars to run in a drill string is (10.19) l = k f w o b w a. as drill collars are uniform tubes of steel with few upsets (changes in id or od) across their length, it is easy to calculate their. Wdc = (wob x sf) ÷ bf. The longer and larger the drill collar, the heavier it will. according to api, there are three ranges of drill pipe length: Range 1 (r1) is the shortest length, more common for sizing production tubing.
