Abstract
The utility model relates to an oil extraction tubular column, in particular to an offshore oil well oil extraction tubular column device. According to the technical scheme, a safety valve control pipeline, a safety valve, an oil pipe, a sleeve pipe, a circulating sleeve, a packer, a connector and a guider are included, the safety valve control pipeline is connected with the safety valve, the lower portion of the safety valve is connected with the oil pipe, the lower portion of the oil pipe is connected with the circulating sleeve which is connected with the guider through the connector, the sleeve pipe is arranged outside the oil pipe, and the packer is arranged between the oil pipe an the sleeve pipe. The offshore oil well oil extraction tubular column device has the advantages that by matching using of the packer and the circulating sleeve, layered oil extraction in an ocean can be better achieved, damage on an oil layer is reduced, and normal extraction of an oil field is guaranteed.
Description
Technical field
The utility model relates to a kind of flow string, particularly a kind of offshore field flow string device.
Background technology
In offshore oil production, offshore oil completion oil production equipment system is mainly by platform completion oil production equipment, subsea-completed well oil extraction system, offshore oil completion oil production equipment is by the production tree on mechanical lifting system and well head in the flow string in well, well, manifold, bank head machinery, Oil/gas Well workover treatment is lowered to after completion tubular column, often need to carry out the job executions such as well-flushing, kill-job and acidifying, can not discharge in time working fluid if acidizing treatment completes, working fluid can damage reservoir.At present, after the job executions such as well-flushing, kill-job and acidifying, need to change tubing string carries out discharge opeing, incurs loss through delay drain time.Working fluid stop meeting in well damages and has reduced effective rise time of oil gas and oil mining efficiency reservoir.In addition, in oil producing operation process, due to Oil/gas Well layer position understanding deficiency is caused to invalid exploitation, at this moment need to change tubing string and change layer exploitation.At present, the completion tubular column that oilfield adopts, majority can not provide circulation canal for oil jacket annular space; Also there is minority that circulation canal can be provided, repeat to open and close circulation canal but can not realize.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of offshore field flow string device is provided.
Its technical scheme is: comprise safety valve control pipeline, safety valve, oil pipe, sleeve pipe, circulating sleeve, packer, joint, guider, safety valve control pipeline connection safety valve, described safety valve bottom connected pipes, oil pipe bottom connects circulating sleeve, circulating sleeve connects guider by joint, the outside of described oil pipe is provided with sleeve pipe, between oil pipe and sleeve pipe, is provided with packer.
Described circulating sleeve comprises top connection, closes cover, adapter sleeve, lower contact, top connection connects lower contact by adapter sleeve, described top connection and lower contact inside are provided with closes cover, close to be enclosed between top connection and lower contact and move, described close to put to be provided with close cover balance pipe, adapter sleeve is provided with draining hole, and the described outside of closing cover is provided with spring key.
The beneficial effects of the utility model are: by being used in conjunction with of packer and circulating sleeve, can better realize the oil production by layer in ocean, reduce the harm to oil reservoir, guarantee the normal exploitation in oil field.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: safety valve control pipeline 1, safety valve 2, oil pipe 3, sleeve pipe 4, circulating sleeve 5, packer 6, joint 7, guider 8;
Accompanying drawing 2 is structural representations of circulating sleeve;
In upper figure: top connection 5.1, close cover 5.2, adapter sleeve 5.3, lower contact 5.4, close cover balance pipe 5.5, draining hole 5.6, spring key 5.7.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises safety valve control pipeline 1, safety valve 2, oil pipe 3, sleeve pipe 4, circulating sleeve 5, packer 6, joint 7, guider 8, safety valve control pipeline 1 connection safety valve 2, described safety valve 2 bottom connected pipes 3, oil pipe 3 bottoms connect circulating sleeve 5, circulating sleeve 5 connects guider 8 by joint 7, the outside of described oil pipe 3 is provided with sleeve pipe 4, between oil pipe 3 and sleeve pipe 4, is provided with packer 6.By being used in conjunction with of packer and circulating sleeve, can better realize the oil production by layer in ocean, reduce the harm to oil reservoir, guarantee the normal exploitation in oil field.
Described circulating sleeve 5 comprises top connection 5.1, closes cover 5.2, adapter sleeve 5.3, lower contact 5.4, top connection 5.1 connects lower contact 5.4 by adapter sleeve 5.3, described top connection 5.1 is provided with and closes cover 5.2 with lower contact 5.4 inside, close cover 5.2 moves between top connection 5.1 and lower contact 5.4, the described cover 5.2 of closing is provided with and closes cover balance pipe 5.5, adapter sleeve 5.3 is provided with draining hole 5.6, and the described outside of closing cover 5.2 is provided with spring key 5.7.
In the course of work: in the time that oil pipe top Move tool moves to the step surface of closing cover end, due to the effect of spring key, Move tool outwards opens, make Move tool and close cover to lock each other.Can be in the inner slip of upper and lower joint under the effect of impact of Move tool.In the time closing the balance pipe of cover and the hole of adapter sleeve and stagger completely, the fluid in annular space just cannot enter oil pipe; In the time closing the balance pipe of cover and the hole of adapter sleeve and communicate, the fluid in annular space just enters oil pipe under pressure, is finally given rise to ground.
