Abstract
The utility model relates to an oil field workover rig, e.g. an integrated pressure balanced workover rig, which comprises a vehicle chassis, a headframe and a control cabin, a pressure balanced work well head device is positioned on the back of vehicle chassis, a rise/fall control cabin is arranged in the middle. The pressure balanced operating device is integrated with workover rig, any other mobile equipment is not required. With the advantages of good mobility, low movement cost, more reasonable structure, the utility model reduces labor intensity of workers greatly and workover cost of oil field, improves work environment of oil field, simplifies operation, improves safety and operability of drillers.
Description
Technical field
The utility model relates to a kind of oil field workover rig, promptly integrated pressure balance workover rig.
Background technology
In prior art, the snubbing serving device has replaced traditional notes that stop to put pressure substantially, annotates the kill-job technology of putting well killing fluid.The snubbing serving device and the workover rig of domestic production are what to separate, during to on-the-spot workover treatment, need transport to the well site to the snubbing serving device with other mobile device, with removing a crane, the coordinating operation worker connects together snubbing serving device and workover rig again, again all hydraulic lines are coupled together, just can carry out workover treatment, but it is very inconvenient to operate, and need be operated together by two people, cooperate very difficulty, and efficient is very low.Because the pulpit of well workover is mounted in the tailstock, this position not only sight line is very bad, and very dangerous in addition.
The utility model content
The purpose of this utility model is the integrated pressure balance workover rig that a kind of high efficiency, safety are provided at above-mentioned deficiency.
Technical solution of the present utility model is: integrated pressure balance workover rig comprises automobile chassis, derrick and pulpit.At the automobile chassis rear portion snubbing serving wellhead assembly is installed, pulpit is arranged on automobile chassis middle part or forward portion, and the bottom connects lifting gear.Make workover rig be equipped with the snubbing serving device with car, structure is further optimized.
The utility model has the advantages that: 1, two equipment of snubbing serving device and workover rig integrate, and do not need other any movement equipment, and movement is good, and the movement cost is low.2, owing to the automatic deploying and retracting of integrated and job platform, all actions just can be finished by hydraulic control system, and structure is more reasonable, greatly reduce working strength of workers, reduce the workover cost in oil field, improved the operating environment in oil field, simplified operation.3, because the reach and the liftable of driller's pulpit have improved the visual field, driller's safety of persons and operability have been improved.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the transversal schematic diagram of pulpit lifting structure.
The specific embodiment
Referring to Fig. 1, integrated pressure balance workover rig comprises the liftable pulpit 3 that automobile chassis 1, derrick 2 and middle part are provided with.At automobile chassis 1 rear portion snubbing serving wellhead assembly 4 is installed.During 4 work of snubbing serving wellhead assembly, can under the hydraulic cylinder effect, release lifting, seat envelope.
Referring to Fig. 2, the lifting gear of pulpit 3 bottoms comprises the X frame 5 that pulpit 3 two bottom sides support, and four ends of each X frame 5 have between roller 6, the two X framves 5 and are connected with axostylus axostyle 7, and axostylus axostyle 7 is by hydraulic cylinder 8 supportings (upright support or diagonal brace).During lifting, hydraulic cylinder 8 posts of living stretch out, and move on the axostylus axostyle 7, and the four rolling of X frame 5 ends 6 is drawn close to the centre, reaches the lifting purpose.Lifting gear has compact conformation, stable characteristics.

1, engine model: WD615.64G
2, engine power: 175kW/2200r/min
3, specified hook carries: 400kN
4, max. hook load: 675kN
5, derrick height: 21m (binodal, long fluid cylinder hoists)
6, operation height: 4m
7, max. speed: 50km/h
8, max. climb slope: 20%
9, minimum ground clearance: 450mm,
Snubbing serving device partial parameters:
1, maximum lifting load: 400kN
2, maximum presses down load: 180kN
3, maximum lifting speed: 0.32m/s
4, maximum presses down speed: 0.49m/s
5, well head sealing load: 21MPa
6, be lowered to tool length :≤1.8m
7, lifting fluid cylinder stroke: 2.8m
