Description
Technical field
The utility model relates to removing paraffin and washing well technical field, the automatic device for removing paraffin and washing well of especially energy-efficient superconductive electric.
Background technology
In oil exploitation process, meeting wax deposition on pit shaft tube wall after oil well production a period of time, the higher then wax deposition of paraffin content in crude oil will be faster and thicker, thus reduce the drift diameter area of oil pipe, add the resistance of oil pipe, make the production declining of oil well, add the consumption of electric energy simultaneously, the wax card of oil well pump or sucker rod when wax deposition is serious, can be caused.Existing processing method has: the techniques such as steam injection wax removal, chemical agent wax removal, boiler car hot water well-flushing; These methods not only also exist formation injury in various degree, and produce many harmful effects to down-hole string, also add the disposal cost in later stage simultaneously, and cost is high, efficiency is low, cause having a strong impact on to the normal production in oil field.
Summary of the invention
The purpose of this utility model is to provide the automatic device for removing paraffin and washing well of a kind of energy-efficient superconductive electric, and when solving existing removing paraffin and washing well, equipment of employing is more, efficiency is low and formation injures in various degree, and the problem that post-processed expense increases.
For achieving the above object, the utility model is by well site power supply with energy-conservation and that heat exchange efficiency is high material, directly heating well head Produced Liquid, when conservative control temperature, Produced Liquid after heating is introduced oil jacket annular space, reaches the object to the heating of down-hole oil tube tubing string; This device is primarily of automatic control cabinet, heating tank, heat exchanger composition.Heating tank inside is carbon brilliant heating panel, conduction oil and vacuum superconductivity tube, and vacuum superconductivity tube extends in heat exchanger, realizes quick, the high-efficiency heating to Produced Liquid by heating, heat exchange; The heating heat exchange steel shell of integration is provided with pressure meter, thermometer, one way valve, breather valve and atmospheric valve, and is connected with liquid inlet and liquid outlet, below automatic control cabinet, power interface is installed.Its implementation procedure is: by the flexible pipe of high temperature high voltage resistant wellhead sampling mouth is connected to the inlet on this device, after the heating of this device, is connected, realizes flushing fluid circulation canal by this device liquid outlet with the sleeve pipe of well head.
The beneficial effects of the utility model:
The utility model can in oil well without stop product situation wash oil wall wax deposition; improve oilwell produced fluid amount; reduce oil well electric quantity consumption; and formation protection to greatest extent; reduce the impact on post-processed simultaneously; thus reduce well-flushing cost, improve operating efficiency and economic benefit, and decrease labour intensity.
The utility model with upper-part be all integrated in movable and skid-mounted on, that can carry out skid drags with vehicle-mounted, the migration easily between well site and well site.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the automatic device for removing paraffin and washing well of energy-efficient superconductive electric, is formed primarily of heat exchanger 1, vacuum superconductivity tube 2, insulation layer 3, the brilliant heating tank 4 of carbon, carbon brilliant heating panel 5, pressure meter 6, thermometer 7, automatic control cabinet 8, feed tube 9, drain pipe 10, one way valve 11, breather valve 12, atmospheric valve 13, power interface 14 and skid 15; Brilliant heating tank 4 inside of carbon is provided with the brilliant heating panel 5 of carbon and vacuum superconductivity tube 2, vacuum superconductivity tube 2 extends in heat exchanger 1, heating heat exchange steel shell lays insulation layer 3, pressure meter 6, thermometer 7, one way valve 11, breather valve 12 and atmospheric valve 13 are installed, and be connected with feed tube 9 and drain pipe 10, power interface 14 is installed below automatic control cabinet 8.
Embodiment 1: oil well sampling mouth is connected to feed tube 9 by high temperature high voltage resistant pipe, open sleeve gate emptying sleeve pipe, by high temperature high voltage resistant Guan Yitou splicing sleeve, one is connected to drain pipe 10, is connected by power interface 14 with well site electrical power control cabinet, open sample cock, observe the situation of pressure meter 6, after stable, close wellhead production valve, according to this well Liquid output situation, give the brilliant heating panel 5 of carbon for electrical heating by automatic temperature control cabinet 8, start to carry out well-flushing; Automatic control cabinet 8, according to the temperature parameter of setting monitor temperature meter 7, then heats stopping when the temperature of thermometer 7 reaches design temperature, completes clean-out service.Open wellhead production valve, close sample cock, disconnect the connection with well site electrical power control cabinet; The high temperature high voltage resistant pipe be connected on drain pipe 10 is connected to atmospheric valve 13, carries out the emptying of liquid in heat exchanger, close sleeve valve afterwards, dismantle the high temperature high voltage resistant pipe connecting sample tap and sleeve pipe, so far complete the removing paraffin and washing well work of this well.
There will be two kinds of situations in concrete operations: complete alternation well-flushing method carried out by the well that 1, Liquid output is low, namely the liquid of output all enters heating tank, temperature can be heated to more than 70 DEG C, such injection annular space, reach more than 65 DEG C (determining depending on wax deposition temperature) until well head goes out liquid temp, and measure pumping-unit motor electric current to no longer declining, well-flushing completes.2, component loops well-flushing method carried out by Liquid output height well, because the liquid measure of output is too many, whole circulation then temperature can not improve, only heat a part and then temperature can be brought up to more than 70 DEG C, produce gate by regulating well head to realize, so a part of Produced Liquid is directly outer defeated, a part of Produced Liquid heat cycles, until well head fluid reaches more than 65 DEG C (determining depending on wax deposition temperature), and measure pumping-unit motor electric current no longer decline well-flushing complete.
Embodiment recited above is only be described preferred embodiment of the present utility model; not design of the present utility model and scope are limited; under the prerequisite not departing from the utility model design concept; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement, all should fall into protection domain of the present utility model.
