Abstract
The invention relates to an apparatus and method for compensating rigidity pipe offset. The invention also relates to a pipeline apparatus for transporting high-pressure airflow in the sea oil-extracting platform. The invention is characterized in that installing the invented compensating apparatus on the pipeline between the oil extracting platform and the separate piles; the compensating apparatus comprises: an end covering (1), an body (2), an spring (3), an spring plunger (4); between the end covering (1) body (2) and ball (6) installed a sphere supporting body (5); installing compensating sealing body (7) on the ball (6); the end covering (1) and body (2) are sealed with bolt (9) and pad (8).
Description
One, technical field: a kind of rigid pipes bit shift compensation method and device belong to the product of petroleum industry system, relate to the tube equipment that a kind of offshore production platform is used for carrying high-pressure liquid.
Two, technical background: at present, at sea the oil field has many offshore production platforms, is used for the production of oil well around it and water injection well is managed and controls.Production platform and oil well, be to connect with Steel Tube Special between the water injection well, in order to carry oil gas or high pressure water, these high pressure pipe lines are at submarine laying, come from the seabed when arriving the production platform place, and independence by production platform one side is connected to the control section on the platform.Usually, the structure of offshore production platform is firm, and independent stake is then weak; When running into wind and waves, independent stake can produce rocking in various degree, and the high pressure pipe line that drives between independent stake and the production platform is subjected to displacement, and makes high pressure pipe line be subjected to very big active force.High pressure pipe line is the displacement that surpasses its elastic range of rigidity, repeatedly takes place pipeline is damaged and have an accident for a long time.
Three, summary of the invention:, the purpose of this invention is to provide a kind of rigid pipes bit shift compensation method and device according to the problem of above-mentioned existence; Solution provides this device that the pipeline between production platform and the independent stake can be rocked with independent stake, and the contraposition shift-in is capable effectively to be compensated.Compensation method of the present invention is achieved in that by the pipeline place between production platform and independent stake this compensation device being installed forms.Suffered active force on the high pressure pipe line is eliminated in the relative displacement that produces because of stormy waves between compensation production platform and the independent stake.Compensation device of the present invention is like this, and it is mainly by end cap, body, spheroid, spring, and the compensation seal of composition elastic structure constitutes.When the pipeline of an end of end cap for fixedly the time, spheroid rotates the angle faces that 360 degree swing around an end conduit axis and carries out automatic compensating error.
The invention has the beneficial effects as follows that when stormy waves makes when being subjected to displacement between production platform and the independence stake, pipeline can not influenced by stormy waves and cause rupture failure with independent stake motion and compensation automatically, reaches the benefit of long service life.
Four, description of drawings: as figure is compensation device structure principle chart of the present invention.
Among the figure 1, end cap, 2, body, 3, spring, 4, spring stack, 5, the spherical support body, 6, spheroid, 7, compensation seal, 8, pad, 9, bolt.
Five, mode of execution: as seen from the figure, compensation device of the present invention is by end cap 1, body 2, spring 3 spring stacks 4 are formed, mounting spherical support 5 between end cap 1 and body 2, spheroid 6, at spheroid 6 places compensation seal 7 is installed, is connected sealing with body 2 by high-intensity bolt 9 and pad 8 at end cap 1.Spheroid 6 is made as the structure that can rotate the compensation space of 360 swings of spending around its axis.When specifically installing and using at the scene, be according to the distance between production platform and the independent stake, the rigidity of independent stake and factors such as sea water advanced and quantity that compensation device of the present invention is installed.
Claims (3)
1, a kind of rigid pipes bit shift compensation method and device is characterized in that compensation method is that install this compensation device and forms at pipeline place between production platform and independent stake.
2, a kind of rigid pipes bit shift compensation method and device, it is characterized in that compensation device is made up of end cap (1), body (2), spring (3), spring stack (4), mounting spherical support (5) between end cap (1) and body (2), spheroid (6), locate to install compensation seal (7) at spheroid (6), be connected sealing with body (2) by bolt (9) and pad (8) at end cap (1).
3,, it is characterized in that the spheroid (6) of compensation device is made as the structure in the compensation space of the swing of spending around its rotational 360 by described a kind of rigid pipes bit shift compensation method of claim 2 and device.
