Description
Technical field
The utility model relates to a kind of wax-proofing device, relates in particular to a kind of oil field intelligent electromagnetic wax-proofing device.
Background technology
Wax is the n-alkane of carbon number 16-64, and at normal temperatures, pure wax is the slightly transparent crystalline solid of white, and density is 880-905kg/m3, fusing point 49-60 ℃.Under the oil reservoir high-temperature and high-pressure conditions, wax contained in the oil is dissolved in the crude oil.When oil extraction, crude oil flows into the oil field pit shaft, rises to the flow process of well head from the shaft bottom from oilbearing stratum, pressure and temperature reduces gradually, when temperature and pressure dropped to wax precipitation point, the wax that is dissolved in the crude oil was separated out with crystal form, and the molecules of wax is to surface of solids diffusion and begin to form tridimensional network, its crystal is grown up, be laminar or block, assemble and be deposited on the tube wall, formed the wax deposition phenomenon.Wax deposition causes the crude stream latus rectum of threading a pipe to dwindle, and oily flowing pressure increases, and can make the oil field produce the wax resistance when serious, causes the oil field underproduction even stopping production.
A lot of methods are being adopted in the oil field aspect wax removal and the wax control both at home and abroad, as mechanical paraffin removal, heating power wax removal, the clear wax control of chemical agent, surface energy wax control (liner coating tubing), the clear wax control of ultrasonic wave, the clear wax control of microorganism and electromagnetism wax control.Wherein, the effect of electromagnetism wax control is better, is one of at present comparatively popular anti-wax technique.As shown in Figure 1; the basic structure of existing electromagnetism wax-proofing device is to be wound with an amount of coil 2 (also being referred to as electromagnetic generator) on one section non magnetic pipeline 1; coil 2 is wrapped with non magnetic insulating layer 3; and be installed in rectification circuit plate 4 on the non magnetic pipeline 1 of non magnetic insulating layer 3 left ends; the rectification circuit plate 4 outer protection outer covers 5 that are provided with, the two ends of non magnetic pipeline 1 are provided with first flange 6.During use, second flange 8 that cooperates on the flowline 7 at first flange 6 at two ends and oil well oil-out place is fixing by securing member 9, for antitheft, nut and bolt with securing member 9 after fixing weld, external alternating current is powered by 4 pairs of coils 2 of rectification circuit plate, energising back coil 2 produces magnetic field, this magnetic field produces strong incentive action to paraffin molecule, the resonance of intramolecular resonance and wax crystalline substance produces and destroys dispersion, the interaction of paraffin and colloid strengthens, the probability that makes paraffin molecule separate out crystallization on non magnetic pipeline 1 reduces, and in addition, magnetic field will cause paraffin molecule to be tending towards orderly arrangement, change the rheological characteristic of paraffin molecule, suppress the accumulation of wax crystalline substance, formed non crystallized free state monocrystal, thereby reached the wax control purpose.
Yet, because first flange 6 and second flange 8 are convex flange, when first flange 6 with after second flange 8 is connected, a gap that is enough to hold saw blade will appear in their junction, like this, the lawless person cuts securing member 9 by the gap easily, steal the electromagnetism wax-proofing device then,, not only can cause device losses in case equipment is stolen, also can interrupt the ordinary production of oil well, cause enormous economic loss.
