Problems solved by technology

[0005] ①The power system of small workover rigs with rotary hoist is driven by diesel engine, which has high installed power, high energy consumption and high noise
[0006] ②The hoisting system of small workover rigs with rotary hoisting adopts a rotary hoisting and lowering mechanism, which has complex kinematic pairs and low mechanical efficiency
[0007] ③The hoisting system of linear hoisting small workover rigs has a complex structure and a low degree of automation
[0008] ④ Rotary hoisting and linear hoisting small workover rigs can only lift and release a single oil pipe, which takes a long time to lift and release the oil pipe, with high labor intensity and low efficiency
[0009] ⑤ The small workover rigs of the rotary lifting type and the linear lifting type all discharge a single oil pipe horizontally on the ground, and the working time for placing the oil pipe is long, the labor intensity is high, and the efficiency is low
[0010] ⑥ Rotary hoisting and linear hoisting small workover rigs cannot implement automatic control and long-distance offline operation

Abstract

A tubing string vertical vehicular full-automatic smart hydraulic workover rig comprises a vehicular chassis, a hydraulic power source, a smart power drive system, a hydraulic automatic energy accumulation system, an offline operating plate, a variable-amplitude oil cylinder, a fixed support, a movable support, a rope sheave distance increasing system, a single cylinder lifting system, a balance head sheave system, an automatic suspension tube lifting system, a tubing string arranging rack, an automatic tube gripping system, an automatic tube moving system, a lifting support frame, a wellhead automatic centering mechanism, an oil pipe length automatic measuring mechanism, an oil pipe automatic fastening and unfastening device, an oil pipe automatic wellhead plate and a multifunctional wellhead oil pipe seat. The tubing string vertical vehicular full-automatic smart hydraulic workover rig is characterized by comprising a vehicular variable-amplitude support system, a tubing string automatic lifting system, a oil pipe automatic fastening and unfastening system and an electric-hydraulic supplying, driving and operating system. By the tubing string vertical vehicular full-automatic smart hydraulic workover rig, oil pipe lifting time is shortened greatly, and work efficiency is increased.

Description

technical field [0001] The invention relates to a vehicle-mounted fully automatic intelligent hydraulic workover rig for vertically placing oil pipe strings, in particular to a workover rig for oil and water well construction operations in oil fields, and belongs to the technical field of advanced manufacturing of oil drilling and workover equipment. Background technique [0002] The most common oilfield workover techniques at home and abroad are roughly divided into two categories: major workover and minor workover according to the complexity of oil and water well operations. The corresponding workover rigs are also roughly divided into There are two categories of large workover rigs and small workover rigs: the overhaul operation mainly solves the complex salvage of oil and water wells in oil fields, the repair of oil well casings, and drilling inside the casing. Most of them are large-scale heavy-duty workover equipment with complete functions; minor repair operations are...
