Problems solved by technology

[0002] At present, the transmission systems of operating equipment such as workover rigs and well drilling rigs mostly use diesel engines to drive mechanical transmissions through friction clutches or diesel engines directly drive hydraulic mechanical transmissions. The shortcomings or deficiencies are: ① Most of them are single The high-power engine only works at full load for a short period of time during the operation of lifting the pipe string. At other times, the horse-drawn trolley operation is performed, and the power loss is large; ②When the pipe string is lowered, the pipe string falls by its own weight, and the output power is in vain Loss, potential energy can not be used, resulting in waste of power

Description

1. Technical field [0001] The invention relates to oilfield operation equipment such as a workover rig and a well drilling rig, in particular to a hybrid power workover rig. 2. Background technology [0002] At present, the transmission systems of operating equipment such as workover rigs and well drilling rigs mostly use diesel engines to drive mechanical transmissions through friction clutches or diesel engines directly drive hydraulic mechanical transmissions. The shortcomings or deficiencies are: ① Most of them are single The high-power engine only works at full load for a short period of time during the operation of lifting the pipe string. At other times, the horse-drawn trolley operation is performed, and the power loss is large; ②When the pipe string is lowered, the pipe string falls by its own weight, and the output power is in vain Loss, potential energy can not be used, resulting in waste of power. 3. Contents of the invention [0003] The purpose of the presen...
