Description
Technical field
The present invention relates to field of ocean engineering, more specifically to a kind of suitable for there is brill, well function is adopted
The main tension compensator load test method of ocean engineering product.
Background technology
With drilling well, adopt the ocean engineering product of well function, such as self-elevating drilling platform, semisubmersible drilling platform, brill
Well ship etc., is provided with auxiliary drill, adopts the main tension compensator of well operations thereon.Derrick system and tension compensator under regular situation
Installed on built product after terminating, shipowner may require that actual job of the simulation actual job operating mode to main tension compensator
It can be tested, to verify that can main tension compensator meet design requirement after installation.
Conventional test method is：By taking self-elevating drilling platform as an example, main tension compensator is generally arranged near well head,
After utilizing cantilever beam sliding overhanging during experiment, special connecting tooling is set on main tension compensator, with being loaded on surface barge
Frock is connected, and then will load frock jack-up by the hydraulic cylinder jacking on tension compensator departs from barge, so as to verify master
The use validity of tension compensator.This test method applies more in self-elevating drilling platform, because jack-up rigs are flat
The cantilever beam and rig floor of platform it is protractile go out main hull, the test tool weight of loading can be placed directly within below main tension compensator
Barge on, test it is more convenient.
But for drill ship, because derrick thereon is fixed structure, the centre in hull or platform, under well head
Side is the maritime mouth of all round closure, so required during the experiment of main tension compensator can not be placed in below derrick with loading load, this
Sample can not just use the method for directly lifting frock weight to carry out the load test of main tension compensator.Semi-submerged platform is with respect to drilling well
The external condition that ship completes main tension compensator load test is slightly good, and the stage under water that may be selected completes, and loading frock can be placed
Lighter and completed to derrick from side in the middle of floating body on barge, due to being operation under water, therefore to experiment timing, peace
The tools such as full strick precaution, performance accuracy have high requirements.Experiment opportunity can only select the increase of stage completion under water to debug work under water first
Measure, the extraneous restriction condition of the meteorological sea situation such as influence safety factor wind, wave, stream is relatively more under water, and underwater operation in addition exists
Not as accurate in land or depressed place on performance accuracy.
The content of the invention
The present invention, which solves drill ship, can not use the method and the main tension compensator water of semi-submerged platform of directly lifting frock
Lower load test by restraining factors it is excessive the problem of.
In order to achieve the above object, the present invention provides one kind and loaded on land using fixed frock is closed, and leads to
Cross the test method that sensor reading determines loading load value.Specifically, it is a kind of to be used for the main tension compensator floor loading of drilling well
The method of experiment, comprises the following steps：
S1, the bottom setting base portion positioned at main tension compensator；
S2, each You Ding top setting force cell positioned at main tension compensator；
S3, the upper surface of each force cell placed a upper cover plate part by adjust pad laminating；
Top fix bar is designed with the middle part of S4, the upper cover plate part；Bottom is provided with the middle part of the base portion
Fix bar；Connected up between the top fix bar and the bottom fix bar by flange in same erect；
S5, by hydraulic oil inlet give tension compensator oily teeming oil so that the oil top of the main tension compensator is equal
Even jacking；
S6, force cell, which reach, keeps a period of time after measured value, until completing load test.
Advantages of the present invention：Conventional carry weight test method is changed into by being passed after jacking by dynamometry by the present invention
Sensor reading reaches a kind of new test method of test objective, can save lot of experiments material and required test space.Can
To implement on land, external condition such as tide when reducing underwater test, restrict with safety factors such as rope, load of platform, test
Opportunity is flexibly safe and reliable.Self-elevating drilling platform, semisubmersible drilling platform, the main tension compensator of drill ship can be met to bear
Lotus is tested, and has a wide range of application.Load value is determined using force cell reading, it is ensured that experiment precision.

Embodiment
As shown in Fig. 1~5, drilling well is divided into base portion 1 with main tension compensator floor loading experimental provision in the present invention
With upper cover plate part 3.
The installation of the present invention and experimental method：
Drilling well need to be negative according to the main appearance and size of tension compensator 7 and experiment with main tension compensator floor loading experimental provision
The condition particular production such as lotus test bit, base portion of the invention and the position of spacer flanger 5 of upper cover plate part are using fastening
Bolt 2 is connected.As shown in Fig. 3, Fig. 5, the base portion of the present invention is first fixed before experiment on special place, it is ensured that during experiment
The factor of the influence safety such as displacement is not produced.Main tension compensator is positioned in the base portion fixed, power benefit is being advocated
Setting force cell 8 on each hydraulic cylinder of device is repaid, then, upper cover plate part 3 is covered and appropriate in force cell and upper lid
The contact surface addition adjust pad 4 of plate part is to keep being horizontally mounted, the connection in the middle of fastening upper cover plate part and base portion
Bolt, as shown in Figure 4.
Hydraulic oil is gradually filled by the hydraulic oil inlet 6 reserved in base portion during experiment, makes the slow jack-up in oil top
Until top is to capping frock top, the data of active force can be shown by force cell, after display data sum is added
Reach after design requirement, kept for a period of time judge whether to meet design requirement by regulation, as shown in Figure 2.
The main tension compensator floor loading experimental rig of the present invention be it is a kind of be connected by screw bolts can closed frock knot
Structure.Main tension compensator is placed in inside frock during experiment, frock forms closing space after being bolted fastening, advocated
Sensor is set between at the top of the oily top ends and frock of force compensating device, surveying number by sensor after oil top hydraulic cylinder jacking reaches
The charge number of test requirements document is met, so as to realize the purpose for completing experiment.The present invention is to the ocean work for boring, adopting well function
The main tension compensator experiment of journey product provides a kind of new test method, compared with similar technique, has the following advantages that：Examination
Test and have a wide range of application, test that safely controllable, experiment opportunity is flexible, test procedure is simple, test accuracy is high.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
