Description
Technical field
The present invention relates to a kind of oil pipe jacking device and the method for carrying out operation using it, the technology suitable for petroleum works is led
Domain.
Background technique
Oil pipe is for being inserted into oil well to extract crude oil out from storage oil reservoir.The length of every Oil-saving pipe is usually arrived at more than ten meters
Tens meters are differed, therefore need to connect oil pipe into use when field operation.The both ends of every Oil-saving pipe are respectively set to public access
The form of head and female connector, pin end refer to that the screw thread that is screwed on is located at the outer wall of oil pipe, and female connector refers to that the screw thread that is screwed on is located at oil pipe
Inner wall.When two Oil-saving pipes connect, the pin end of an oil pipe is inserted into the female connector of another oil pipe and is screwed.Due to oil
Need to connect use between pipe, therefore the length of single-unit oil pipe can not be too short, otherwise will increase connection number.The connector of oil pipe
Be be easiest to occur leakage and corrosion place, this is because joint location connection when can occur inevitably collide and by
To damage, and the content of carbon dioxide and hydrogen sulfide is larger in oil well.It, will once damage location is exposed in corrosive media
Accelerate its corrosion, gently then reduces the service life of oil pipe, it is heavy then scrap whole oil pipe, it results in significant economic losses.
Fig. 6 shows the method for connected pipes in the prior art.As shown, generally being risen in the prior art using arm extending type
Loop wheel machine 4 slings upper oil pipe 51, by its be already inserted into oil well and be aligned by the lower oil pipe 52 that chucking device 53 maintains,
Then the two is screwed on.There are two significant deficiencies for this kind of form of construction work:
Firstly, since the limitation of working space, lifting machine is generally required to be maintained a certain distance with oil well.When oil pipe is up to
At more than ten meters, the Hydraulic jip of lifting machine can be made up to tens meters.Not only make the big discounting of the safety of construction site in this way
Button, but also can operating cost be substantially increased.
Secondly, by upper oil pipe and lower oil pipe alignment when there is no any ancillary measure, can thus make oil pipe and
It frequently collides between lower oil pipe, will certainly cause to damage on the pin end and female connector of oil pipe, make its intensity and sealing
Property is by serious influence, it is most likely that so that whole oil pipe is scrapped, to result in significant economic losses.
Therefore, need one kind that can reduce the limitation of working space, avoid using arm extending type lifting machine simultaneously in the prior art
The oil pipe construction technology damaged at oil connection can be minimized.
Summary of the invention
