Description of the embodiments
The following describes the utility model in detail by way of specific examples in connection with fig. 1-2.
Examples
A wellbore wax control viscosity reduction pour point depressant comprising a base pipe 1, wherein: a plurality of baffle rings 101 are fixedly sleeved on the base pipe; a protective outer tube 3 is welded between the baffle rings; a plurality of high temperature resistant magnetic blocks 2 which are adhered to the base pipe are arranged between the protective outer pipe and the base pipe, samarium cobalt magnets are selected as the high temperature resistant magnetic blocks, the high temperature resistant magnetic blocks are axially spirally arranged at intervals on the base pipe, and the high temperature resistant magnetic blocks forming an axially spirally distributed structure can relatively increase the flow velocity of crude oil of the base pipe and simultaneously prevent the crude oil from waxing on the inner wall of the base pipe; the protective outer tube has the function of providing the outer layer of protection for the high-temperature-resistant magnetic block and avoiding the damage of the high-temperature-resistant magnetic block; the outer wall of the port close to the base pipe is sleeved with a coupling 4 for connecting the base pipe with the base pipe; a gap is reserved between the coupling and the baffle ring close to the coupling, and because the strength of the base pipe is highest, the base pipe part at the gap is the base pipe clamp section 102 which is used for being matched with a clamp to move the base pipe, so that the damage of the protective outer pipe and the internal high-temperature-resistant magnetic block caused by the furniture clamp on the protective outer pipe with lower strength is avoided. In order to enable the magnetic alloy block to be closely attached to the base pipe, the high-temperature-resistant magnetic block is arched. In order to facilitate the installation of the base pipe, the base pipe is connected with the coupling through threads.
The working principle of the utility model is as follows:
the utility model is arranged below a pump or at the inflection point of wax precipitation, and crude oil in a crude oil layer is precessed to a base pipe through an oil pump.
The high-energy field is obtained through the specially arranged high-temperature-resistant magnetic blocks, when crude oil in a shaft passes through the base pipe, polar molecules generate induced magnetic moment under the action of magnetic force lines of the energy field, and simultaneously the magnetic force lines of the energy field precess. The electron spin magnetic moment and electron circulation during precession generate an additional magnetic field, which is opposite to the external magnetic field. Thus, when crude oil enters a magnetic field, the crude oil overcomes the magnetic field force to do work, the molecular internal energy is increased, and the viscosity reduction effect is achieved.
Because of the similar precession speed of wax molecules, the wax molecules are arranged into a molecule string along the direction of magnetic force lines. Promote the molecular strings to form microcrystals in advance, and the adjacent molecular strings are mutually repelled due to the same arrangement direction and same polarity. The molecular strings are not easy to combine into a large network wax crystal, and the large network wax crystal can not be adsorbed on the pipe wall to form a wax layer, so that the wax-preventing effect is achieved.
When crude oil moves to a magnetic swirl flow guide pipe area in a base pipe under the reciprocating action of an oil pump, the crude oil generates a magnetic swirl effect in the guide pipe under the action of a giant magnetic flow guide pipe, the giant magnetic swirl guide pipe can rapidly improve the crude oil moving speed, the effect of pushing wave to assist billow is achieved, the oil quantity of a pump passing through a valve is increased instantaneously, the passive oil inlet of the valve in the past is changed into the active oil inlet at present, the speed and the oil quantity are improved by 1 time compared with the original speed and the oil quantity, and the pumping efficiency is greatly improved, so that the effects of lifting assistance and single well oil increasing are achieved.
The utility model is arranged under a pump or at a wax deposition inflection point, solves the problem of wax deposition in oil well treatment by adopting an advanced physical method, simultaneously has the specific viscosity reduction and pour point reduction effects, effectively reduces the oil extraction cost, reduces the influence on the environment, improves the oil extraction efficiency and economic benefit, has the remarkable characteristics of simple process, energy conservation, easy installation and the like, and has very wide market application prospect.
