Headframe type mechanical and electrical integrated well repairing machine

Abstract

The invention discloses a headframe type mechanical and electrical integrated well repairing machine, which comprises a well repairing frame, a crown block, a big hook, a speed sensor, a speed reducer roller, a brake and a motor or transmission equipment, wherein a hydraulic station, the motor or transmission equipment and the speed reducer roller are sequentially arranged on the upper part of the bottom of the well repairing frame; a rail formed by arranging a steel wire rope is arranged in the middle of the well repairing frame on the upper part of a fixed frame; the motor or transmission equipment is connected with the speed reducer roller through a belt wheel and a belt, or connected with the speed reducer roller through a gear, or a chain wheel and a chain; one end of the steel wire rope on the speed reducer roller is fixed on the speed reducer roller, the other end of the steel wire rope is fixed at the bottom of the well repairing frame through the crown block and a movable pulley on the big hook; and a control circuit of the motor is connected with an intelligent control cabinet, and the intelligent control cabinet is connected with a console. The headframe type mechanical and electrical integrated well repairing machine is simple in integral structure, the mounting space and the transportation cost are reduced, the mounting procedures are simplified, and the preparation period for repairing a well is not required.

Description

technical field [0001] The invention relates to an oilfield workover machine, in particular to a derrick type mechatronics workover machine. Background technique [0002] At present, there are two main types of workover equipment in oilfields, one is the split workover equipment combined with the well drilling rig and the workover frame, and the other is the vehicle-mounted workover equipment with its own derrick. These two types of workover equipment also have the following disadvantages in application: the first type of workover equipment requires a car trailer and a vertical derrick truck to drag the well rig and the workover frame to the well site respectively, and the transportation cost is high and the preparation period is long The second type of workover equipment has a high purchase cost, most of which are only used in oil well overhaul operations, and 85% of oil well workover workload is minor workover operations. In the operation process, no matter what kind of eq...

These two types of workover equipment also have the following disadvantages in application: the first type of workover equipment requires a car trailer and a vertical derrick truck to drag the well rig and the workover frame to the well site respectively, and the transportation cost is high and the preparation period is long The second type of workover equipment has a high purchase cost, most of which are only used in oil well overhaul operations, and 85% of oil well workover workload is minor workover operations. In the operation process, no matter what kind of equipment, the original power system Driven by a fuel oil engine, the operation is labor-intensive, noisy, and the smoke pollution is serious, which greatly affects the health of the workers. In today's urbanization of the mining area, the residents near the oil well are also suffering from it.
