Description

A kind of day car owner passively combines heave compensation experimental rig
Technical field
Passively combine heave compensation experimental rig the present invention relates to a kind of day car owner, belong to marine drilling field.
Background technology
In recent years, with the development of the fast development of China's economic, particularly petroleum chemical industry and automobile industry, stone The supply of oily, natural gas is increasingly not enough.Along with On shore Oil Development is petered out, to marine petroleum exploitation, particularly deep-sea The exploitation of oil, it has also become inexorable trend.
In deep-sea oil drilling well development process, offshore drilling ship or floating drilling platform under extraneous stormy waves, action of ocean current, Heave, surging, swaying, yawing, rolling, the motion of yawing six-freedom degree will be produced.Wherein heave can cause drill string with floating Drilling platforms carries out heave movement, causes the pressure of the drill between drill bit and shaft bottom to change, and reduces efficiency, increases cost, influence Drillng operation is smoothed out.Under severe sea situation, drill bit even can lift-off shaft bottom, initiation drilling failure.Therefore need to match somebody with somebody Standby heave compensator, to reduce influence of the heave movement to drillng operation.
At present, floating marine drilling platforms heave compensator is broadly divided into dead line heave compensator, fast line heave and mends Repay device, travelling block type heave compensator and crown-block heave compensator.Wherein, dead/fast line heave compensator is to steel The abrasion of cord is too big, and compensation system reaction speed is slow, compensation precision is not high;Tourist bus type heave compensator takes floor space Greatly, fluid cylinder sealing is more, and liquid line is long, and friction loss is big;Although crown-block heave compensator also has, equipment center of gravity is high, repair guarantor The shortcomings of supporting inconvenient, but its occupancy floor space is small, and pipeline is short, and sealing is few, and steel wire rope and the pulley room of compensation device do not have There is relative motion, the life-span of steel wire rope is unaffected, be a kind of current most widely used, technically reliable degree heave compensation higher Device.
According to power supply mode, fluid pressure type heave compensation system can be divided into active, passive type again and semi-active type is (main Passive hybrid compensation).The compensation precision of active heave compensation system is high, has good compensation effect and adaptability, but need Consume substantial amounts of energy;Passive type heave compensation system hardly consumes power, it is not necessary to provide energy, but compensation precision It is low, exist compared with large time delay;Semi-active type heave compensation system combines the above two advantage, however it is necessary that increase intermediate energy turning Exchange device, system architecture is complex.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of day car owner passively combines heave compensation examination Experiment device, the need for meeting to marine floating type drilling well correlative study.
To meet above-mentioned purpose, the technical solution adopted in the present invention is:
