Centralizing string and restoring string for horizontal well casing pipe dislocation and restoring process of centralizing string and restoring string

The invention discloses a centralizing string and a restoring string for horizontal well casing pipe dislocation and a restoring process of the centralizing string and the restoring string so as to solve the problem that existing dislocation wells with the casing pipe dislocation and inner diameter coincidence degree ranging from 30-50% in an oil field are incapable of being centralized and restored. The centralizing string comprises a booster, a hydraulic anchor and an oil pipe, and an eccentricity centralizing hanger, the booster and the hydraulic anchor are sequentially connected through the oil pipe. The restoring string matched with the centralizing string in use comprises an oil pipe and a casing pipe restoring tool which are connected, an insertion pipe is connected at the bottom of a cylinder of the casing pipe restoring tool, and a casing pipe is inserted into an outer positioning cylinder of the eccentricity centralizing hanger. The restoring process is particularly applicable to thermal recovery horizontal well casing pipe dislocation restoring works and similarly applicable to other casing pipe dislocation horizontal wells. The centralizing string and the restoring string and the restoring process can be used for effectively restoring the dislocation casing pipe at a horizontal segment of the horizontal well, have no chemical pollution to an oil layer and are wide in application range, simple in construction steps and capable of effectively reducing production cost.
