Two, background technology
When traditional offshore oil exploitation submarine cable and the construction of oil pipeline maintenance activity, generally all utilization structure is split typely promptly to inhale mud and separate towards mud, the gas-lifting type ooze sucker that general two people operate, the ooze sucker of this structure, bury the maintenance of the darker submarine cable of mud and pipeline under the ocean for oil exploitation and brought into play effect, but it exists following shortcoming or deficiency simultaneously: 1. only inhale and do not dash or only dash and do not inhale, dash and inhale the mud inefficiency; 2. the negative pressure that traditional gas-lifting type ooze sucker relies on air pressure to produce merely, absorption mud amount is not enough, and the mud degree of depth of dashing that does not reach job requirements reaches towards the mud amount; 3. only adopt water under high pressure to wash the mud face open, do not reach the effect that effective prevention is back-silted, the mud degree of depth of dashing of requirement has reached, but on a flood current becomes silted up again, causes the repetition construction operation.
Three, summary of the invention
The purpose of this utility model provides a kind of marine gaslift formula towards mud-sucking device, adopts feed pipe, air supply pipe, suction mud pipe, towards the co-ordinative construction of soil-suction head and nozzle, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Marine gaslift formula described in the utility model comprises that towards mud-sucking device feed pipe, air supply pipe, suction mud pipe reach towards soil-suction head.Described feed pipe, air supply pipe, suction mud pipe reach and are installed on one jointly towards soil-suction head, are installed on towards soil-suction head and inhale mud pipe one end, and feed pipe one end is installed on soil-suction head, and air supply pipe one end passes towards soil-suction head and is connected with the suction mud pipe.
Wherein, described is a ring cavity structure towards soil-suction head, and nozzle is installed on it.Described nozzle is four, and hoop is distributed on the ring cavity of soil-suction head.Described suction mud tube end towards the soil-suction head front end is equipped with the protective cover that the U-shaped round steel by right-angled intersection constitutes.Described air supply pipe one end is after passing towards the soil-suction head end, and crooked the insertion inhaled in the mud pipe.Described air supply pipe one end is after passing towards the soil-suction head end, and crooked the insertion inhaled 30-50cm in the mud pipe.The other end of described feed pipe is equipped with adpting flange.
The utility model has following advantage compared with prior art:
1, uses water under high pressure to dash the operating type of inhaling, improved greatly and dashed the operating efficiency of inhaling mud, for the quality time is won in construction.
2, can increase and dash the degree of depth of inhaling according to the real work needs.
3, the silt with the operating area removes at a distance, slows down the speed of back-silting, and reduces influence that construction operation is caused, avoids the repetition operation.
4, compact conformation, floor space is little, and it is dexterous convenient to use;
5, to the sudden accident of production safety under water, can clear up suspicious region under water timely, investigate thoroughly location of accident and state, win the quality time, reduce the loss, save a large amount of construction costs for construction;
6, processing, manufacturing, easy to maintenance, cost is low;
7, obvious towards the suction effect, be convenient to construction operation, improve the safety factor of diver's underwater operation greatly.
8, spray bath flow velocity degree of the present utility model, sludge volume estimation and actual test effect are as follows: calculate according to jade-like stone Nova Lip river husband's formula, hydrodynamics formula and drilling well handbook formula, the spray bath flow velocity degree that leaves nozzle 100cm place is greater than 5m/s; Actual test is left the water velocity at nozzle 100cm place for greater than 5m/s, can guarantee to quick start seabed earth.
Sludge volume estimation:, adopt 9m according to laboratory test and site operation experience
3The gas bubble pump of/min, the plasma discharge pressure head can reach more than the 3m.Calculate gaslift plasma discharge amount Q=7.7 * (0.25 * 3.14 * 0.2 * 0.2) * 3600 ÷ 2=450 (m by formula V=7.7 (m/s)
3/ h); Slurries mud content (volume ratio) is calculated by 3%, and the total amount that can get rid of earth in 4 hours is: 450 * 4 * 3%=54 (m
3).
