发明名称 DETERMINING THE LIFE SPAN OF AN ELASTOMER IN A MOTOR
摘要 A method for determining a remaining life span of an elastomer in a motor. The method includes running a downhole tool into a wellbore. The downhole tool includes a mud motor having a rotor and a stator. At least one of the rotor or the stator includes, or is at least partially made from, an elastomer. A number of cycles before the elastomer fails may be predicted. A number of cycles during a time period may be determined. A change in a remaining life span of the elastomer over the time period may be determined, based upon the number of cycles before the elastomer fails and the number of cycles during the time period.

主权项 1. A method for determining a remaining life span of an elastomer in a motor, comprising: running a downhole tool into a wellbore, the downhole tool including a mud motor, the mud motor having a rotor and a stator, wherein at least one of the rotor or the stator has an elastomer; predicting a number of cycles before the elastomer fails; determining a number of cycles during a time period; and determining a change in a remaining life span of the elastomer over the time period, based upon the number of cycles before the elastomer fails and the number of cycles during the time period.
