Description
Technical field
The present invention relates to deepwater drilling equipment technical field, a kind of semi-active type sky for deepwater drilling operation
Car heave compensation system.
Background technology
Along with the fast development of national economy in recent years, the demand of petroleum resources is sharply increased by China, imbalance between supply and demand day
Benefit is severe, has become as the bottleneck difficult problem that restriction China future economy develops in a healthy way further.To this end, country's tailor
" China's 21 century sustainable development petroleum resources strategical planning ", the Major Strategic target call of this planning " from global strategy
Eye, it is ensured that the supply steady in a long-term of petroleum resources ", it is necessary to fully " playing the basic guaranteeing role of domestic petroleum resources ", and
Ensure the external dependence degree of the oil gas supply safety line less than 60% in from now on 20 years." national economy and social development simultaneously
12 five-year-plan outlines " the most clearly propose to want " rational exploitation and utilization marine resources, positive Development of Marine oil gas, ocean fortune
The new industries such as defeated, marine engineering equipment manufacture, strengthen that ocean is basic, perspective, the R&D intensity of guardian technique ", carry
High China ocean science level, strengthens ocean exploitation ability.March to deep-sea, carry out oil and gas development utilization and become China
The main development direction of Oil Strategy from now on, promotes degree domestic and the technical merit of marine oil and gas equipment, and this is that China is real
Execute oil and gas development move towards deep-sea and safeguard the technical foundation of maritime rights and interests.(Liao's plan is holy. Chinese Sea petroleum drilling and mining equipment manufacturing industry
Progress with suggestion [C]. Chinese ocean petroleum and gas world summit collection of thesis, 2006. Zhou Shouwei, Jin Xiaojian, Zeng Hengyi, etc. sea
Ocean petroleum equipment and facility support the platform [J] of Offshore Oil Industry. China's engineering science, and 2010,12 (5): 102-
112. Liu Qing friends, Xu Tao. deep sea drilling heave compensator present status in China and thinking of development [J]. Southwest Petrol University's journal
(natural science edition), 2014,36 (3): 1-8.)
In carrying out deep-sea oil gas exploitation drilling operation course, need to utilize floating drilling platform to stop as Active workings and personnel
Integral basis ground, owing to the effect of the natural load such as external wind, wave can make the heave movement of semisubmersible drilling platform generating period, should
The drill string making hook be hung is followed platform and is done reciprocal heave movement together by motion.When drilling platforms rising displacement is excessive, greatly
Hook strip is moved drillstring motion and makes drill bit depart from shaft bottom, affects the drilling efficiency of drill bit；When drilling platforms decline displacement is excessive, drill string
Caused Bottom Hole Bit Weight In A to be more than regulation the pressure of the drill by compression, drill bit may be damaged by pressure or damage drill string, causing drilling safety hidden danger.For avoiding
The generation of drilling safety accident and reduction drillng operation cost, need the heave of DRILL-STRING SYSTEM hung to deep sea drilling platform to transport
Move and take suitable motion compensation measure.
Heave compensator is as the drillng operation key equipment during deep-sea oil gas exploitation, it is possible to because of floating
Drilling platforms heave movement and the drill string heave displacement that causes carries out effective compensation, thus ensure drillng operation efficiency and use peace
Entirely, drillng operation cycle and cost are reduced.Floating drilling platform is broadly divided into two kinds for the compensation way of drill string heave movement:
1. in drill string pipe string, telescopic drill rod is set up；2. on drilling platforms, increase all kinds drill string heave compensator.Flexible brill
Bar is owing to cannot regulate Bottom Hole Bit Weight In A, and operation easier is big, is the most gradually replaced by the latter.Drill string heave compensator according to
Compensation process medium power presentation mode can be divided into passive type, semi-active type and active three classes；According to compensation device structure type
Crown-block heave compensator, hook block heave compensator, dead line heave compensator and winch heave compensation dress can be divided into
Put four classes.
Crown-block heave compensator is as putting into an on-the-spot actually used and correlative compensation technology development class liter the most earlier
Heavy compensation device, because its technology maturation and security reliability are high, obtains at present in deep water floating drilling platform and drill ship
Extensively application.This device mainly by floating overhead traveling crane, drive compensation system, hydraulic support system (by compensation hydraulic cylinder assembly, hydraulic pressure
Pipeline, control valve, accumulator etc. form), guider (being made up of directive wheel, guide support frame etc.), steel wire rope rocker arm body
And the parts composition such as corresponding control system.
Currently used crown-block heave compensator mainly uses hydraulic-driven compensating form, in fluid power system due to
There is a large amount of fluid pressure line and control the hydraulic component such as valve so that the compensation of drilling platforms heave movement is rung by the system that compensates
Certain hysteresis quality should be there is, the compensation speed of crown-block heave compensator can be produced impact with efficiency；
Owing to compensation system existing a large amount of hydraulic component, hydraulic system is made easily to occur revealing under bigger pressure condition, shadow
Ring safety and the dependability of compensation system, owing to the problems such as hydraulic system leakage or hydraulic valve Pipeline Failure are caused
Work accident, compensation system can be caused to need shut-down (breakdown) mainteance, therefore increase system maintenance difficulty and overall operation cost.In sky
In car heave compensation motor process, some drillng operation needs floating overhead traveling crane to be locked in a certain level altitude position, it is simple to make
The carrying out of the operating processes such as upper, the shackle during industry.
Floating overhead traveling crane is in heave compensation motor process, and the power end for Mechanical Driven mode can make to be positioned at Drilling derrick
Floating overhead traveling crane in top produces and waves, and is unfavorable for steadily carrying out of movement compensation process.
Steel wire rope rocker arm body is in the crown-block heave compensator that floating drilling platform carries out heaving movement compensation
Important component part, drilling line is mainly played guide effect and reduces steel wire rope in drilling well strand by steel wire rope rocker arm body
Winding number of times on car, it is achieved reduce the abrasion of steel wire rope and improve the purpose in service life.This mechanism existing does not has energy
Amount storage and release passively compensate function, but the drill string weight that drilling line is hung has ton up to a hundred, uses overhead traveling crane heave
Compensation device is in drillstring motion compensation process, and steel wire rope rocker arm body part has a large amount of available energy, this part energy
Amount all cannot be obtained by motor process.
Existing overhead traveling crane heave compensation system uses hydraulic-driven compensating form, hydraulic support system not to have locking merit
Can, and compensation process can produce wave, additionally, steel wire rope rocker arm body kinergety cannot be used.Conventional overhead traveling crane liter
The compensation efficiency that heavy compensation system generally exists floating overhead traveling crane is the highest, and floating overhead traveling crane is not sufficiently stable during pumping
And the problem such as the reliability of each mechanism is the highest.
