This will make errors in the drain pressure controlling and cause accidents. Thus it’s necessary to install oil tube righting fittings near the spatial location of the collar finder, to ensure safety, accuracy and reliability of the collar finder. The main purpose of the design is to solve the problems of increasing the oil tube righting fittings and improving accuracy of the collar finder in the process of operating under pressure, thus ensuring the safety of operating under pressure and further to play its advantage in the process of well workover operation. The device has four contact points to stablize the level position of the pipe string and to keep the righting system balance. Meantime the contact section use the roller structure to ensure the collar smoothly pass through the righting fittings with minimal friction. The rollers are installed on the pistons.
