Description
Technical field
The invention belongs to the oil well repairing operation apparatus field, relate in particular to a kind of continuous pipe working rig, be applicable to each stage of drilling well, oil recovery, can carry out operations such as sand washing, well workover, cementing, salvaging, well logging, reaming hole, scale removal, completion and drilling well.
Background technology
The oil well repairing operation machine is subjected to foreign technology and price fixing all the time, has limited its application of petroleum well workover industry at home to a certain extent, influences the development of China Petroleum.
Increasing along with special well heads such as China's horizontal well, fishbone well, extended reach wells, a lot of operations adopt conventional workover rig can't finish, and the work pattern that existing working rig mostly adopts individual tubes to connect, labor intensity of operating personnel is big when workover treatment, and operating efficiency is low.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art part and provides a kind of workover treatment labour intensity low, and is easy to operate, the continuous pipe working rig of high efficiency.
For achieving the above object, the present invention is achieved in that
A kind of continuous pipe working rig, it comprises cylinder, injection head, blowout preventer set, guider and manages continuously; The port of described guider and injection head is fixedly connected; Described injection head and blowout preventer set are fixedly connected; Described continuous pipe is wound on the cylinder, and the one end seals in injection head through guider.
As a kind of preferred version, the present invention also is provided with carrier loader, places liftable control room and folding arm lorry-mounted crane on the carrier loader.
Further, guider of the present invention can adopt the gooseneck guider.
Further, the present invention is fixed with the injection head supporting leg in the bottom of described injection head.
The present invention is described as " omnipotent implement ", is applicable to each stage of drilling well, oil recovery, can carry out operations such as sand washing, well workover, cementing, salvaging, well logging, reaming hole, scale removal, completion and drilling well.The present invention is owing to adopt the work pattern of continuous pipe, so need not in the operation process to have alleviated working strength of workers to making up a joint, and improved operating efficiency.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation under the complete machine movement state of the present invention;
Fig. 2 is the vertical view of Fig. 1 of the present invention.
Among the figure: 1 is carrier loader; 2 is the liftable control room; 3 is cylinder; 4 is injection head; 5 are folding arm lorry-mounted crane; 6 is the injection head supporting leg; 7 is the sebific duct cylinder; 8 is blowout preventer set; 9 is the gooseneck guider; 10 is continuously pipe.
The specific embodiment
As shown in the figure, a kind of continuous pipe working rig, it comprises cylinder 3, injection head 4, blowout preventer set 8, guider 9 and manages 10 continuously; Described guider 9 is fixedly connected with the port of injection head 4; Described injection head 4 is fixedly connected with blowout preventer set 8; Described continuous pipe 10 is wound on the cylinder 3, and the one end seals in injection head 4 through guider 9.
The present invention also is provided with carrier loader 1, places liftable control room 2 and folding arm lorry-mounted crane 5 on the carrier loader 1.
For strengthening guide effect, guider 9 of the present invention can be selected the gooseneck guider.
For making the injection head monolithic stability, the present invention can be fixed with the injection head supporting leg in the bottom of described injection head 4.
It shown in the figure movement state of this equipment.Carrier loader 1 is the delivery unit of complete machine and for whole working provides power, and all the other each parts all are fixed on the carrier loader 1.The present invention is in working order the time, can operate folding arm lorry-mounted crane 5, at first folding arm lorry-mounted crane 5 is sling blowout preventer set 8 and is linked to each other with well head from carrier loader 1, again with gooseneck guider 9 with after injection head 4 is connected, slinging links to each other with blowout preventer set 8, and injection head supporting leg 6 is supported on four angles of injection head 4, plays the supplemental support effect, in the course of the work, folding arm lorry-mounted crane 5 hangs injection head 4 all the time.Be raised up to duty by 3 transpositions of hydraulic control cylinder and liftable control room 2, operation in liftable control room 2, cylinder 3 cantilevers are risen rise to duty, index drum 3 will be managed 10 continuously and be passed injection head 4, in addition can be by injection head 4 and cylinder 3 synchro switches, control injection head 4 can be realized the synchronization action of injection head 4 and cylinder 3, finishes continuous pipe and is lowered to and trips out in the well.Realize pumping into of liquid or gas by the pipeline interface on the cylinder 3 at last, realize operation.
The pipe working rig adopts single vehicular structure continuously, a continuous pipe of rigidity that is fit to well depth is wrapped on the working drum, by the centralized Control in the control room, adopt hydraulic system to realize the coordination of cylinder and injection head, well head is sent into or tripped out to continuous pipe, finish well workover and other operations, realize the real-time demonstration and the storage of parameter simultaneously by the signal of telecommunication.
