Description

A kind of detection of sea-bottom oil-gas transport pipeline Hydrate Plugging and plug-removing device
Technical field
The invention belongs to oil-gas pipeline streaming flow safeguard technology fields, are related to a kind of submarine oil-transportation gas pipeline The detection of Hydrate Plugging and plug-removing device.
Background technique
It is increasingly mature with offshore oil and gas resource production technique, the flowing safety guarantee of sea-bottom oil-gas transport pipeline also at For the hot issue of petroleum research field.Sea-bottom oil-gas transport pipeline have temperature is low, pressure is high, flow distance is long, maintenance The features such as difficult, under cryogenic high pressure, water of the methane in natural gas easily and in pipeline, which combines, generates hydrate.And hydrate exists The blocking that deposition aggregation in oil and gas pipeline will cause oil and gas pipeline often needs after oil and gas pipeline blocking It to be solved time for a long time, can not only bring huge economic loss, also there is great security risk.
There are mainly two types of the methods for preventing oil and gas pipeline Hydrate Plugging at present, respectively heating and inhibiting Method.Wherein heating is mainly to improve the temperature of fluid in oil and gas pipeline, when fluid temperature (F.T.) is higher than in oil and gas pipeline When the corresponding Phase Equilibrium Temperature of pressure, hydrate will not aggregation formation, the generation of hydrate is prevented with this.But this method is mentioning A large amount of energy can be consumed when high fluid temperature (F.T.), therefore will increase the cost of oil-gas mining.Inhibiting method will mainly inhibit Agent is injected into oil and gas pipeline, and the phase balance condition of hydrate can be improved in inhibitor, so that hydrate is more difficult to generate, but It is that inhibitor is not only expensive, environment can be impacted toward contact.But while using above-mentioned method, transported in oil gas The phenomenon that still will appear Hydrate Plugging in defeated pipeline, therefore there is still a need for simple and easy measures to solve asking for Hydrate Plugging Topic.
Summary of the invention
The present invention provides a kind of detection of sea-bottom oil-gas transport pipeline Hydrate Plugging and plug-removing devices, are sea-bottom oil-gas Transport pipeline Hydrate Plugging provides a kind of device for decomposing hydrate, and may be implemented that device is recycled.
Technical solution of the present invention:
A kind of detection of sea-bottom oil-gas transport pipeline Hydrate Plugging and plug-removing device, including heating system, positioning system, inspection Examining system, Weighting system and shell 7;
The shell 7 is made of high pressure resistant stainless steel, with each to the hollow ball shape structure in symmetrical hole channel 8, The high pressure in oil and gas pipeline can be born, and guarantees that device suspension can follow fluid even running in a fluid;On shell It respectively can guarantee that fluid is accessible to symmetrical hole channel 8 to flow in and out, oil and gas pipeline will not be blocked;
The heating system includes battery 1 and heater 2, and multiple heaters 2 are arranged symmetrically in shell 7, passes through electricity Pond 1 powers, and common realize heats device;
The positioning system includes locating module 3, and 3 linking parsing module 5 of locating module is used for real-time recording and sending Location information is analyzed and determined for analysis module 5;
The detection system includes motion sensor 4 and analysis module 5, and motion sensor 4 passes through electric wire linking parsing Module 5, acceleration or vibration signal for sensing device;The velocity information of 5 combined positioning system of analysis module and movement pass The acceleration information of sensor 4, judges whether oil gas transport pipeline blocks;
The Weighting system is metal block 6, is placed in shell 7, changes the weight of device according to different fluids, makes to fill It sets and follows fluid motion in oil gas transport pipeline;
Battery 1, locating module 3, analysis module 5, motion sensor 4 and multiple heaters 2 is sequentially connected in series one In a circuit, more series circuit CB common batteries 1, locating module 3, analysis module 5 and motion sensor 4 are realized.
Effect and benefit of the invention is that it is stifled to provide hydrate when Hydrate Plugging can occur in oil gas transport pipeline Location information is filled in, and starts heat release in blocking position and destroys balancing each other for hydrate, decompose hydrate and dredge hydrate and is stifled Fill in section.It solves the problems, such as to occur in oil gas transport pipeline not judging blocking position when Hydrate Plugging, while also avoiding The complex ways such as traditional needs decompression solve the problems, such as to block.In addition, the present invention can be recycled for multiple times, and can be according to function The device that multiple and different diameters can actually be made is used cooperatively, be suitable for multiple fluid and pipeline, improve economy and The scope of application.
Detailed description of the invention
Fig. 1 is a kind of detection of sea-bottom oil-gas transport pipeline Hydrate Plugging and the sectional view of plug-removing device.
In figure: 1 battery;2 heaters;3 locating modules;4 motion sensors;5 analysis modules;
6 metal blocks;7 shells;8 hole channels.
Specific embodiment
A specific embodiment of the invention is described in detail below in conjunction with technical solution and attached drawing.
Fig. 1 show detection and the plug-removing device structural schematic diagram of sea-bottom oil-gas transport pipeline Hydrate Plugging.
Weighting system is adjusted according to the density of fluid in pipeline first, then by the present apparatus in oil gas transport pipeline Inlet is put into, as fluid flows in pipeline.Assemble and when blocking pipeline when encountering hydrate and starting deposition, device can be with Fluid there is abnormal speed.According to the location information of positioning system, the current speed of device and position can be calculated, together When motion sensor measure acceleration information.Analysis module can judge that hydrate, which currently whether occurs, to be blocked up according to above-mentioned information Plug, when being judged as Hydrate Plugging, device can be by blocking position delivering, and will start heating system, and device starts Exothermic decomposition hydrate, thus dredge blockage.When starting to occur hydrate aggregation in oil and gas pipeline, minor diameter device warp It is out-of-date to will appear velocity anomaly, it is put into big diameter apparatus in oil gas transport pipeline inlet at this time, when big diameter apparatus reaches phase When should assemble position, start exothermic decomposition hydrate, to achieve the purpose that unclog the pipe, in addition, fluid can pass through device Hole channel flow freely into and bleeder, oil and gas pipeline will not be blocked.
