Abstract

The invention discloses a portable hydraulic top drive device, which is mainly composed of a top drive (1) and a hydraulic pump station (2). The top drive is mainly composed of a hoisting mechanism, ashell, an output torque mechanism, a spindle, a faucet and an anti-torque mechanism, the hydraulic pump station delivers hydraulic oil into the output torque mechanism to drive the output torque mechanism to work, the spindle is driven to rotate and then connected with an external working part to drive the external working part to conduct workover operation, and thus the function of top driving is achieved. The top drive part in the portable hydraulic top drive device adopts a hydraulic motor as a power source, electricity connecting is not needed, convenient conditions are provided for limitation to field work, the number of component parts is small, the structure is simple, the weight is small, carrying is convenient, power of the portable hydraulic top drive device is not reduced compared with power of an existing top drive for electricity connecting, the portable hydraulic top drive device can be suitable for various sensitive areas, in-time overhaul of all oil wells is achieved,and the oil field recovery ratio and the development effect are ensured.

Description

technical field [0001] The disclosure of the present invention relates to the technical field of oil field workover devices, in particular to a portable hydraulic top drive device. Background technique [0002] With the continuous deepening of oilfield development, the downhole technical conditions of oilfields are becoming more and more complex. Conventional workover rigs equipped with drill floors have many problems in workover operations, and the workload of overhaul is gradually increasing. However, for wells near sensitive areas such as roads, factory buildings, and high-voltage lines, when the existing technology is used for overhaul, road closures, factory buildings, and high-voltage lines need to be demolished, which greatly increases the workover cost. In addition, some wells are located in living areas and sensitive areas. Due to the narrow well site and limited equipment conditions, these wells cannot be processed in time, which seriously affects the productivity ...
