Abstract
The utility model pertains to a device prevents or limits crystallization of salt, and in particular relates to a pipe type high magnetic field oil well salt preventing device, which comprises a pipe type casing with two ends connected with a pipeline. A permanent magnet is arranged inside the casing. As the permanent magnet is arranged inside the casing, form of double electric layer arranged on surface of colloidal particle is promoted by the oil and water of field oil well under the action of the magnetic field based on the theory of magnetic induced colloidal effect, and the possibility of the forming of the colloidal particle is increased and the stability is enhanced. As the colloidal particles of the metastable are increased, the process of the crystallization of the salt of the oil water is inhibited and the object of the salt preventing is achieved.
Description
Technical field
The utility model belongs to the device that prevents or limit saline crystallization, relates in particular to a kind of tubular type highfield oil well salt preventing device that is used for petroleum well.
Background technology
In petroleum well, because saline crystallization, fuel-displaced being obstructed, oil well pump or sucker rod stuck phenomenon happen occasionally, and treating method is dosing or heating water-soluble salt usually, and the producing well of electric pump is installed, the unavoidable lifting heavy metal rod that adopts carries out drifting, these technical measures, production efficiency is low, the cost for oil production height.
Summary of the invention
The purpose of this utility model is to provide a kind of salt preventing device that can prevent the saline crystallization in the pumpingh well.
The utility model is to realize like this, and it comprises the tubular shell that two ends link to each other with pipeline, and permanent magnet is set in the housing.
The housing two ends are connected with pipeline by joint, permanent magnet ringwise, its inwall is provided with annular protective jacket; Protective jacket two ends outward flanging is clamped by joint, and contacts with inner walls; Annular preserving and sealing bed course is set between protective jacket and permanent magnet; Preserving and sealing bed course two ends outward flanging, and contact with inner walls; Between protective jacket flange and preserving and sealing bed course flange lead ring is set, the preserving and sealing bed course is clamped by lead ring.
Between the inner face of joint and the protective jacket turnover face joint ring is set; The joint inner face is provided with the ring-type convex cone, with it the annular groove that is complementary of Dui Ying joint ring end face setting and this convex cone; Form interference fit between described belt convex cone and the groove; Protective jacket external surface and preserving and sealing bed course inner surface bonding.
The utility model is owing to be provided with permanent magnet in housing, according to " mangneto colloid effect " theory, profit in the producing well is under the effect of magnetic field, promoted the formation of water-borne glue body particle surface electric double layer, the probability that colloidal particle is formed increases, and stability improves, because metastable colloidal solid increases, the saline crystallization process is suppressed in the profit, thereby reaches the purpose of anti-salt; The protective jacket of tubular has completely cut off contacting of permanent magnet and chemical substance, has avoided the permanent magnet to be subjected to chemical attack and magnetic force is weakened; Permanent magnet has further been protected in the setting of preserving and sealing bed course; Because the joint ring end face is provided with the spill annular groove, the joint inner face is provided with convex cone, makes joint ring closely to be squeezed between joint inner face and the protective jacket turnover face, has good sealing effectiveness.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model structure as shown in Figure 1, it comprises barrel-type casing 5, have cavity in the barrel-type casing 5, annular protective jacket 7 is set in the housing cavity, housing 5 forms and is threaded with top connection 1, lower contact 10, and protective jacket 7 internal diameters are identical with joint 1,10 internal diameters, adhesive permanent magnetism body 4 in the toroidal cavity that protective jacket 7 and housing are 5, protective jacket 7 two ends outward flangings, and contact with housing 5 inwalls; 4 of protective jacket 7 and permanent magnets are provided with annular preserving and sealing bed course 6; Preserving and sealing bed course 6 two ends outward flangings, and contact with housing 5 inwalls; Between protective jacket 7 flange and preserving and sealing bed course 6 flange lead ring 3,8 is set; Protective jacket 7, lead ring 3,8 closely contact with housing 5 inwalls, and these parts axially compress mutually.
On the end face of joint sealing device is set, concrete structure is: the joint inner face has a step, at step end face joint ring 2,9 is set; The ring-type convex cone is set on the joint step end face, and Dui Ying joint ring is provided with the spill annular groove therewith; The convex cone angle is about 60 °, and the spill annular groove angle of joint ring is about 50 °.
When joint was inwardly tightened, joint ring tightly was squeezed between joint inner face and the protective jacket turnover face, and like this, annular convex cone and spill annular groove are meshing with each other, and have guaranteed sealing effectiveness.
Being provided with of protective jacket 7 is as follows, at first protective jacket is launched part and carry out clip, require the clip five equilibrium uniform, length is identical, is placed on then in the preserving and sealing bed course, under the effect of special tool expansion force, make protective jacket external surface and preserving and sealing bed course inner surface bonding firmly, behind the some hrs, again with protective jacket two-port place flange (special tool operation), make that it is bonding, compress.As the selection of protective jacket material, not only to consider characteristics such as acidproof, alkaline-resisting, oil resistant, heatproof, but also will consider non magnetic and plasticity.
The utility model is owing to be provided with permanent magnet in housing, according to " mangneto colloid effect " theory, profit in the producing well is under the effect of magnetic field, promoted the formation of water-borne glue body particle surface electric double layer, the probability that colloidal particle is formed increases, and stability improves, because metastable colloidal solid increases, the saline crystallization process is suppressed in the profit, thereby reaches the purpose of anti-salt.
The protective jacket of tubular has completely cut off contacting of permanent magnet and chemical substance, has avoided the permanent magnet to be subjected to chemical attack and magnetic force is weakened; Permanent magnet has further been protected in the setting of preserving and sealing bed course; Because the joint ring end face is provided with the spill annular groove, the joint inner face is provided with convex cone, makes joint ring closely to be squeezed between joint inner face and the protective jacket turnover face, has good sealing effectiveness.
The magnetic field intensity height of the utility model highfield salt preventing device seals and antiseptic property is good, high temperature resistant, anti-salt is effective, long service life.
