Description
Technical field
The utility model relates to a kind of submarine pipeline electric heating plug removal equipment, belongs to the oilfield machinery field.
Background technique
The oil transport pipeline in seabed because a variety of causes (as amount of infusion not enough etc.), tends to take place the plugging accident, if do not consider method for removing blockage, in case just the accident intractable appears, even scrap, will cause heavy losses to country.The submarine pipeline difficulty of construction is big, the cost height, for guaranteeing the security of operation of pipeline, prevent to run affairs with fixed attention so take place, effective method is to adopt Skin effect companion thermal process, but this companion's thermal process difficulty of construction is big, the cost height, generally be used for viscous crude (or the high oil that coagulates) pipeline tracing, not high for those viscosity, the oil transport pipeline that paraffin content is lower uses this method uneconomical.
The model utility content
The purpose of this utility model is the problem at above-mentioned existence, and a kind of effective, economic submarine pipeline electric heating plug removal equipment is provided.
The technological scheme that its technical problem that solves the utility model adopts is as follows: submarine pipeline electric heating plug removal equipment of the present utility model, comprise gathering and transporting device, power supply, cable and oil transport pipeline, described oil transport pipeline comprises oil pipe and is enclosed within the sleeve pipe of its outside, between oil pipe and sleeve pipe, be provided with the thermal insulating layer, two ends at oil transport pipeline are provided with terminal box respectively successively, gathering and transporting device and power supply, between terminal box and gathering and transporting device, be provided with insulated flange, centre at oil transport pipeline also is provided with insulated flange, insulated flange both sides in the middle of oil transport pipeline are respectively equipped with a short-circuited conducting sleeve, cable is drawn from the power supply at two ends respectively and is connected to terminal box, and oil transport pipeline is that the boundary is respectively at the oil pipe of both sides with the insulated flange of centre, short-circuited conducting sleeve, form electric loop between sleeve pipe and the power supply.
In described oil transport pipeline, also be provided with the insulation water-ring every one section.
Per 500 meters also are provided with the insulation water-ring in described oil transport pipeline.
Working principle: in the time of when high-power three phase transformation single phase industrial frequence power supplys are added between oil transport pipeline and the sleeve pipe by power cable on, just constitute the Skin effect heating unit between oil transport pipeline and the sleeve pipe, oil transport pipeline is heated, (for viscous crude is the above 5-10 of inflection temperature ℃ when temperature reaches predetermined value, coagulating oil for height is the above 5-10 of freezing point temperature ℃) if pipe-line system is pressurizeed, crude oil in the plugging just can flow, and pipeline is just by de-plugging.
The beneficial effects of the utility model: the utility model has been used the Skin effect principle, electric current is flowed at the outer surface of oil pipe and the internal surface of sleeve pipe, and bushing outer surface does not have voltage and current, forms the good insulation performance structure, work safety very; Connect between the terminal box of power end and the gathering and transporting device at pipeline in addition and be provided with insulated flange, guaranteed the insulation of pipeline and system, make that electric heating de-plugging procedures system is unaffected, also be provided with water-ring at pipeline enclosure, anti-sealing enters the slit between sleeve pipe and the oil pipe; In the middle of oil transport pipeline of the present utility model, be provided with insulated flange, make the oil transport pipeline of its both sides form electric loop respectively, when having only the line clogging of a side, only need open the power supply heating de-plugging of stopping up end and get final product, device easy construction of the present utility model, simple and safe operation.
