Description
Technical field
It is isolated the present invention relates to a kind of submarine pipeline and blocks pigging material and preparation method thereof.
Background technique
Currently, if there is the barriers such as double-edged fine-toothed comb in pipeline, conventional pipe cleaner can not in the draining inerting operation of submerged pipeline
Positive normal open ball, while needing to carry out each component in pigging train isolation closure, thus need to select there is deformation after Yi Huifu, whole
The good product of body, to play plugging action in pigging train.
The draining that fresh water, gel and ethylene glycol are injected to solve 18 cun of tap lines by LD22-1 to Tee Joint Point direction is done
The problem of not allowing blowby between two component of fresh water during dry and ethylene glycol.It was found that guar polymer solution and gel are handed over
The gel that connection agent etc. configures has good stabilization, pressure resistance, sealing characteristics, can assist composition pigging train, and can be with
The ratio of fresh water and ethylene glycol in pigging train is reduced, when extra large pipe branch line leads to ball pigging to keep good closure isolation effect
Fruit.
However the configuration of this kind of gel can only determine that configuration gel is different by the research in terms of experiment progress concentration proportioning
Dosage under concentration, and the gel effect (viscosity, intensity, conservation rate etc.) configured.Therefore it is preferred to need to carry out gel formula,
It will be in the pigging process of prepared gel application Yu Haiguan with customized solution.
Summary of the invention
It is a primary object of the present invention to overcome disadvantages mentioned above existing for existing product, and provide a kind of submarine pipeline isolation
Pigging material and preparation method thereof is blocked, the material prescription is reasonable, and have and the performance that pigging train respectively forms directly is isolated,

It six, is 5 to 15%, parts by weight by the guar polymer being sufficiently swollen and configured weight percent concentration
For 1 to 5 Guar rubber cross linker, another container is injected by 10:1 rate, and is sufficiently stirred, keeps the guar gum being sufficiently swollen poly-
Object and the configured full cross-linked 30min of Guar rubber cross linker are closed, the product of reliable in quality is obtained.
Embodiment one:
Closure pigging is isolated in submarine pipeline of the present invention and is pumped into SX type static mixer with material, is injected after mixing
The submarine pipeline of DF13-2 project, which, which blocks pigging material, can make the Blend proportion of ethylene glycol and fresh water in pigging train
Example from 73% to 65% is reduced to 15% to 13%, guarantees that the ethylene glycol in pigging train is not influenced to destroy by a large amount of fresh water,
The absorbent drying effect for guaranteeing ethylene glycol, to realize the effect of good cleaning-drying inerting of the pigging material to submarine pipeline
Fruit.
Embodiment two:
Submarine pipeline of the present invention is isolated using pump and compressor and blocks pigging with 30 side of material, 10 side of fresh water, ethylene glycol
(MEG) 20 sides inject in LD22-1 to 18 cun of tap lines in Tee Joint Point direction, and each medium, which is in, after standing 1 hour stablizes shape
State constitutes pigging train, does not blend so as to play the role of each constituent in isolation closure pigging train.It is arranged in pigging
It is found when vehicle discharge line end, section medium does not blend before and after pigging train in pipeline, dry cleansing in pipeline, in pigging train
Pipeline is smoothly discharged in each medium, and using effect is good.Each medium transports terminal platform, the discharge pipe being equipped with by platform
Each medium is discharged into dirt-discharging purifying facility and is handled.
Submarine pipeline isolation of the present invention blocks the working principle and advantage of pigging material:
1, submarine pipeline isolation, which blocks pigging, has good viscoplasticity, easy deformation with material, can lead in the duct
Barrier, reducer pipe are crossed, and keeps sealing over long distances.
2, submarine pipeline isolation, which blocks pigging material itself, can carry impurity, can remove from pipeline a large amount of broken
Bits, there is no the risk of traditional pipe cleaner card in the duct.
3, the pigging train that closure pigging material and traditional pipe cleaner form being isolated by the submarine pipeline can reduce clearly
The abrasion of pipe device, enables pigging train to execute pigging operation in longer pipeline, reinforces pigging effect.
4, submarine pipeline isolation, which blocks pigging, has good isolation and sealing effect with material, can solve and pipeline
Isolation blocks the problem of different fluid (oil-water, oil-oil, water-vapour, oil-gas) correlation.
5, submarine pipeline isolation closure pigging material outer layer is water base, and local resistance is small in the process of running, will not
Excessive wear inner wall of the pipe, energy consumption several times smaller than conventional pigging train energy consumption in pigging process.
The pre- operation construction purpose of pipeline is to reach the dry inerting of draining, so that pipeline is transported under the operating condition of clean dried
Row, it is therefore desirable to carry out the construction of pigging train.Contain fresh water and ethylene glycol in pigging train, fresh water is used to clean pipeline miscellaneous
Matter, ethylene glycol are used to the residual moisture in extraction duct, and the two needs to be isolated to play a role, to avoid blending general use
Pipe cleaner carries out closure isolation, but traditional pipe cleaner plugging effect is limited, and often having fresh water to be mixed into ethylene glycol leads to ethylene glycol
Failure blocks pigging using submarine pipeline isolation of the invention and carries out closure isolation with material.Gel is studied by a large number of experiments
Good isolation plugging effect is played in pigging train, and submarine pipeline isolation is obtained from project acceptance inspection examining report
Blocking pigging material makes the blending rate from 73% to 65% of ethylene glycol and fresh water be reduced to 15% to 13%, and plugging action is isolated
Well, it has ensured that the ethylene glycol in pigging train is not influenced to destroy by a large amount of fresh water, has effectively improved the water-absorbing dry of pigging train
Dry effect.
The present invention can preferably complete the configuration and injection operation of submarine pipeline pigging gel, and the advantage of its economical and efficient
Preferable verifying has been obtained in the circular track test of land.The present invention successfully realizes DF13-2 project sea and manages the seabed gone into operation in advance
The high-efficient disposition of pipeline cleaning gel and pipeline inject, and the present invention is suitable for playing isolation closure pigging operation in pigging train.
The present invention blocks the 18 cun of branch solved in cleaning process by LD22-1 to Tee Joint Point direction in submarine pipeline gel
Road pipeline injects the dry problem of draining of fresh water, gel and MEG, and using effect is good, has reached expected purpose.
Submarine pipeline isolation of the present invention blocks pigging material and is applied to pipeline cleaning, isolation closure etc., Ke Yiqi
To the unrivaled functions and effects of traditional pigging technology.Due to the inexpensive, easy to manufacture, safe and environment-friendly, efficient of gel, energy
Low advantage is consumed to play a significant role in pipeline cleaning technical field.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all
It is any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, still falls within
In the range of technical solution of the present invention.
