Petroleum electrohydraulic workover rig with two operation chamber

The utility model relates to a petroleum electrohydraulic workover rig, in particular to a petroleum electrohydraulic workover rig with two operation chambers. The petroleum electrohydraulic workover rig is characterized in that the workover rig includes two operation chambers; one operation chamber is arranged below a derrick; the additional operation chamber is arranged on the platform of a blowout preventer; and a transfer switch is arranged between the two operation chambers. The additional operation chamber consists of a box body, a cushion plate and support legs, wherein the box body is fixed on the support legs through bolts and the cushion plate; and an operation device is arranged in the box body. Compared with the prior art, the petroleum electrohydraulic workover rig can improve the work vision of operators so as to facilitate operation, and the original operation system in the original operation chamber is kept. Accordingly, the petroleum electrohydraulic workover rig has the advantages of double operation systems, no interferences, convenient disassembly/assembly, and can achieve the control requirements for various operations.
