Background technology:
Crude oil is in exploitation is produced, crude oil is by well head earthward in the process of flowing, reduction along with temperature in the pit shaft, viscosity of crude rises, when temperature is reduced to the wax precipitation point of crude oil, on the shaft in wall that adheres to, can form the wax deposition phenomenon, increased the flow resistance of crude oil, reduce production efficiency, increased the load of oil pumper and the hot washing period of oil well.And to viscous crude, high exploitation of coagulating oil, then need steam injection, electrical heating, add chemical agent and mix process matched therewiths such as thin oil, not only wasted the energy, increased the difficulty of measure technology, and underground equipment caused serious corrosion, increased the production operation cost greatly.At above-mentioned situation, Chinese patent ZL97223735.6 discloses a kind of oil well magnetic pour viscosity reduction device that is used for viscous crude, high-solidifiability oil well exploitation, mainly is made up of inner core, many group permanent-magnets and parcel coating etc., and the outer wrapping layer is for soaking the glass wool cloth of epoxy resin.This device is that the glass wool cloth that will soak epoxy resin is wrapped on the magnet, because non-dismountable, can not recycling after magnet fragmentation or glass wool cloth wearing and tearing, and suppressed the development of this technology.Chinese patent ZL 200820187690 discloses a kind of oil well magnetic paraffin control device, comprises connector, electromagnetic transducer and switch board.This device is mainly used in the clear wax control of surface line, owing to need supporting electromagnetic conversion parts, if be applied to the down-hole, cost will improve greatly.
Summary of the invention:
The purpose of this utility model is to provide a kind of dismountable oil well magnetic paraffin control viscosity reduction machine.Oil well magnetic paraffin control viscosity reduction machine easy to maintenance, as can to reuse, be used for the field produces well, the crude oil for inhibiting wax deposition, reduce viscosity of crude, so reduce oil pumper load, reach the prolongation hot washing period, reduce or alternative other technology, realize the purpose that oil well is energy-conservation, produce.
The utility model is mainly by connecting thread; Fixed end; Connecting thread; The magnet sheath; Permanent magnet; Magnet groove; Magnetic paraffin control viscosity reduction machine body; Positioning bolt; Centralizer body; Set upright part and form, connecting thread is connected with magnetic paraffin control viscosity reduction machine body, and fixed end is arranged on it, and the magnetic paraffin control viscosity reduction machine is external the magnet sheath; On magnetic paraffin control viscosity reduction machine body, permanent magnet is arranged; Magnet groove is arranged in the permanent magnet; Positioning bolt is arranged at magnetic paraffin control viscosity reduction machine body bottom, and is connected with centralizer body, sets upright part on the centralizer body.
This externally has a magnet sheath to the utility model owing to adopted the magnetic paraffin control viscosity reduction machine; On magnetic paraffin control viscosity reduction machine body, permanent magnet is arranged; Magnet groove is arranged in the permanent magnet; Positioning bolt is arranged at magnetic paraffin control viscosity reduction machine body bottom, and is connected with centralizer body, sets upright part on the centralizer body.The oil well magnetic paraffin control viscosity reduction machine that can reuse, easy to maintenance, be used for the field produces well, the crude oil for inhibiting wax deposition, reduce viscosity of crude, so reduce oil pumper load, reach the prolongation hot washing period, reduce or substitute other technology, realize the energy-conservation purpose of oil well.Make that simple, on-the-spot dismounting is easy to maintenance, improve application life greatly, reduced the production run cost, obtained remarkable economic efficiency, have broad application prospects.
Description of drawings:
Accompanying drawing 1 is an agent structure schematic diagram of the present utility model.
Specific embodiment
As shown in Figure 1, the utility model is by connecting thread 1; Fixed end 2; Magnet sheath 3; Permanent magnet 4; Magnet groove 5; Magnetic paraffin control viscosity reduction machine body 6; Positioning bolt 7; Centralizer body 8; Set upright part 9 and form, connecting thread 1 is connected with magnetic paraffin control viscosity reduction machine body 6, and fixed end 2 is arranged on it, and magnet sheath 3 is arranged outside the magnetic paraffin control viscosity reduction machine body 6; On magnetic paraffin control viscosity reduction machine body 6, permanent magnet 4 is arranged; Magnet groove 5 is arranged in the permanent magnet 4; Positioning bolt 7 is arranged at magnetic paraffin control viscosity reduction machine body 6 bottoms; and be connected with centralizer body 8; set upright part 9 on the centralizer body 8; permanent magnet 4 magnet materials of magnetic paraffin control viscosity reduction machine are Nd-Fe-Bo permanent magnet material; magnetic Circuit Design, assembling to magnet draw by laboratory experiment; the magnet groove 5 that particular arrangement is arranged on the magnetic paraffin control viscosity reduction machine body 6, semicircular Nd-Fe-B permanent magnet 4 are adsorbed in the magnet groove 5, and permanent magnet is played effectively fixing, protective effect.The protection skin of permanent magnet 4 is columnar poly-tetrafluoro magnet sheath 3.
The design is a kind of dismountable oil well down-hole magnetic paraffin control viscosity reduction machine, is mainly used in viscous crude, height coagulates the device that in the oily producing well crude oil is played wax control, viscosity reduction.
This device at first designs magnetic circuit before installation, adopts the means of laboratory experiment, i.e. crude oil viscosity-temperature curve contrast experiment before and after the magnetic treatment screens, designs, assembles optimum magnetic circuit with this.
