Description

A kind of oil recovery low-frequency pulse magnetic paraffin control device
Technical field
The utility model relates to a kind of low-frequency pulse magnetic paraffin control device, is used for preventing that paraffin and dirt from separating out in fluid crystallizations such as crude oil, extraction liquid, reduces viscosity of crude, reduces the crude oil flow resistance, belongs to the oilfield exploitation technical field.
Background technology
Main at present employing the in oil field mixed the temperature that the hot-water process improves fluid, with the deposition of control paraffin in flowline.The fluid water content of from the stratum, extracting out is very high; Especially in weather cold in winter; Therefore fed distance is very long again, must water mixing be heated to higher temperature, and this causes the oil field to expend a large amount of energy every year heating with the water mixing that fund is used for the Crude Oil Transportation process.
Oil pipe and the very easily wax deposition fouling of petroleum pipeline inwall; Take certain measure to carry out the wax control de-plugging; As compression shock, heat wash, method such as mechanical paraffin removal, paraffin control with inhibitor, compression shock, heat are washed, mechanical paraffin cutting; Be in pipeline, to have formed the dewaxing method that adopts under the situation of deposition, can only wax removal can not wax control, only as the complementary measure of mixing hot-water process's oil transportation.And paraffin control with inhibitor method complex process, oil field and environment produced pollute.
Summary of the invention
The purpose of the utility model provides a kind of low-frequency pulse magnetic paraffin control device for the problems and shortcomings that solve above-mentioned prior art just; Thereby can effectively prevent paraffin and the dirt in fluids such as crude oil, extraction liquid crystallization separate out; Reduce viscosity of crude; Reduce the crude oil flow resistance, and oil exploitation has reduced cost.
The purpose of the utility model realizes through following technical proposal: a kind of oil recovery low-frequency pulse magnetic paraffin control device, to form by shell 1, soft iron pipe 2, steel pipe 3, extension tube attached 7 and low-frequency pulse magnetic controller 8, and described shell is the oval cartridge type that stainless steel is processed; Steel pipe is the oval tubular isometric with shell that nickel steel is processed; Install in the enclosure, curl electromagnetic coil 5 on the steel pipe tube wall, the soft iron pipe is installed in the enclosure; Be fixed on the soft iron pipe with base plate 6; Shell, steel pipe and soft iron pipe are connected with the low-frequency pulse electromagnetic processor around 4, two coils of volume electromagnetic coil on the soft iron tube wall on same center line; Extension tube attached one end is connected with the down-hole oil pick-up tube, and the other end is connected with the oil field oil storing tube.
The utility model is the basis with the electromagnetic theory; Freq-variable electronic circuit and electromagnetic technique with the advanced person combine, and can make original oil pumper no longer need any wax control measure, as adding the chemicals wax control; Can also reduce watering quantity; Even stop water mixing and water mixing temperature, and prolong hot washing period, reduce cost for oil production.In addition, device can also reduce viscosity of crude, improves the flowability of crude oil in petroleum pipeline, reduces transporting resistance.
Because differences such as the temperature of paraffin, viscosity, pH value under the various producing well different conditions, also ten minutes is complicated for contain colloid, the asphalitine etc. of wax dirt composition, and the natural frequency of all kinds of molecular weight is different.Utilize the variable-frequency pulse technology, the magnetic field intensity that control crude oil low-frequency pulse magnetic paraffin control viscosity reduction machine produces is carried out cyclically-varying by a certain rule.The frequency that changes can cover all waxs, the natural frequency of dirty matter, thereby reaches the effect of paraffin removal, wax control, antiscale.
The electromagnetism wax-proofing apparatus produces the electromagnetic field that a low-frequency pulse changes; Oil well paraffin prevention antiscale assembling produces the electromagnetic field of a conversion; By the magnetic conduction character of medium in oil pipe, polished rod and the pipe, in the magnetic field that can shroud any fluid composition of the inner formation of oil pipe.Extend time between well-flushings, promote the useful fate that recovers the oil, and make oil pumper hang down the carrying row, reduce power consumption, function definition is widely all arranged in all kinds of oil fields.
Owing to take technique scheme, make the utility model compared with present technology have following advantage and effect:
(a) this device not only can make original oil pumper no longer need any wax control measure, reduces cost for oil production, can also reduce viscosity of crude, improves the flowability of crude oil in petroleum pipeline, reduces transporting resistance.
(b) simple in structure, safe and reliable, easy for installation, only carry out the flange connection and get final product on ground.
(c) adapt to field work, Applicable temperature scope-50 ℃~+ 65 ℃.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the technology of inventing is further specified:
A kind of oil recovery low-frequency pulse magnetic paraffin control device by shown in Figure 1, is made up of shell 1, soft iron pipe 2, steel pipe 3, extension tube attached 7 and low-frequency pulse magnetic controller 8; Described shell is the oval cartridge type that stainless steel is processed, and steel pipe is the oval tubular isometric with shell that nickel steel is processed, and installs in the enclosure; Curl electromagnetic coil 5 on the steel pipe tube wall, the soft iron pipe is installed in the enclosure, is fixed on the soft iron pipe with base plate 6; Shell, steel pipe and soft iron pipe are connected with the low-frequency pulse electromagnetic processor around 4, two coils of volume electromagnetic coil on the soft iron tube wall on same center line; Extension tube attached one end is connected with the down-hole oil pick-up tube, and the other end is connected with the oil field oil storing tube.Two magnetic fields produce different frequency, possibly improve the paraffin removal effect.
