At home, steel bend pipe is generally all adopted with being connected of jacket platform technique in the end of submerged pipeline, the rigid riser structure that namely jointly is comprised of vertical bend pipe and horizontal expansion bend pipe and is put into the edge after the submerged pipeline horizontal segment is connected and is located at standpipe card on standpipe stake or the jacket leg.According to designing requirement, submerged pipeline lay finish after, need imbed following 1.5 meters of seabed nature mud face.
Because the structure distribution situations such as the submerged pipeline of jacket root, cable are complicated, if adopt the dredger ditching, easy submerged pipeline, submarine cable injury to this place, simultaneously, because trenching machine can only be along the submerged pipeline straight line moving, can't carry out ditching to the horizontal expansion bend loss of riser bottom and bury underground, the submerged pipeline that these reasons have all caused the jacket root afterwards all can't the ditching pipe laying in completion and is exposed on sea bed, has formed certain potential safety hazard.In recent years, domestic Tan Hai field began this is furtherd investigate, and not only the technology such as bionic aquatic weed was introduced, and had been studied the unsettled improvement technology such as snag, had all obtained preferably effect.But because the economic input that these technology relate to is larger, increased to a certain extent the investment of submerged pipeline, therefore, find the easy jacket root submerged pipeline method for embedding of a kind of relatively economical just to seem particularly important, this also is the needs that improve the standpipe mounting technique, ensure the safe operation of submerged pipeline simultaneously.
Summary of the invention
The purpose of this utility model is to provide high-pressure water jet gaslift immersed tube facility, can eliminate in advance to a certain extent the unsettled potential safety hazard of jacket root submerged pipeline, the depth of burying that guarantees the submerged pipeline standpipe meets design requirement, make the installation of jacket root submerged pipeline more be tending towards safety, rationally, very necessary for the safe operation of the exploitation of beach shallow-water oilfield and submerged pipeline.
In order to reach above-mentioned purpose, the utility model provides following technological scheme, and high-pressure water jet gaslift immersed tube facility comprise high pressure airlift unit, water jetting at high pressure device, and described high pressure airlift unit is connected on the water jetting at high pressure device; Described high-pressure water jet gaslift immersed tube facility also comprise and are connected and fixed device, and by being connected and fixed device submerged pipeline and facility self linked together.
Described water jetting at high pressure device is comprised of two water jetting at high pressure pipes, high pressure water nozzle and inverted U pipe; The high pressure water nozzle tilts 20
0It is inboard to be distributed on the water jetting at high pressure pipe, and the water jetting at high pressure pipe also is listed in the submerged pipeline both sides, and water jetting at high pressure tubular axis line and submerged pipeline axis are in same plane and are parallel to each other; Inverted U pipe lower end connects two water jetting at high pressure pipes, and the upper end is the high pressure water nozzle and connects high-pressure water pump by high pressure hose.
Described the be connected and fixed plate of device for mutually docking that be connected and fixed is fixed on submerged pipeline on the water jetting at high pressure pipe of both sides.
Described high pressure airlift unit is comprised of high pressure hose and high pressure valve, and high pressure hose is connected to the water jetting at high pressure pipe outside side by side, and the high pressure valve is distributed on the high pressure hose downside.
Compared to prior art, the beneficial effects of the utility model are: the utility model utilizes high-pressure water jet gaslift immersed tube technology, be high pressure water liquefaction submerged pipeline bottom earth, pressurized gas eject mud from pipe trench, utilize ocean current that earth is taken away, thereby formation pipe trench, submerged pipeline utilize own wt to sink to pipe trench.These facility utilize pattern and the arrangement of jetting nozzle, rationally determine layout and the bind mode thereof of discharge jet, guarantee the submerged pipeline connection of this device and jacket root after, by high-pressure water jet gaslift immersed tube, the pipeline sinking is put in place.
These facility mainly form by being connected and fixed device, water jetting at high pressure device, high pressure airlift unit three large systems.Being connected and fixed device utilizes submerged pipeline and this facility bearing pin to link together; The water jetting at high pressure device connects high-pressure water pump, utilizes nozzle to penetrate water jets under high pressure, liquefaction earth; The high pressure airlift unit connects air compressor, utilizes valve that mud is ejected from pipe trench.This facility easy construction, short construction period, workable, saved a large amount of ship machine expense, material cost, cost of labour, so that the investment cost of submerged pipeline reduces greatly, have good economic benefit and social benefit.
