Abstract
The present invention provides a kind of wax control paraffin removal equipment in Petroleum Production, is provided with wax-proofing agent in the wax control paraffin removal equipment, can reduce wax removal measure and expense, saves hot wash oil, protects oil reservoir；Wax card accident is reduced, guarantees the smooth execution of balanced production and plan, after taking wax control measure, it is seldom that tube inner wall adheres to wax, well-flushing can carry out together with other measures, to reduce pump number and wax removal time and workload, reduce pumping unit and oil well damage；Wax control measure can reduce the load of sucker rod up-down stroke, reduce current of electric, save energy consumption.
Description
Technical field
The present invention relates to field of petroleum machinery more particularly to a kind of wax control paraffin removal equipment in Petroleum Production.
Background technique
Crude oil is from underground mining to ground, and since significant change occurs for the geological conditions such as pressure, temperature, original dissolution is in the oil
Paraffin some can be precipitated and be attached to crude oil gathering pipeline inner wall, oil pipeline internal diameter can be caused to narrow for a long time, it is former
Oil flow rate decline, flow reduce, and oil pipeline can be caused to block when serious.
The common control and remove of well paraffin technology in oil field mainly have mechanical paraffin removal technology, heating power Paraffin Removal technology, surface can technology,
Chemical agent Paraffin Removal technology, magnetic paraffin control technology and microbial wax control etc..The principle of mechanical paraffin removal mechanical treatment process is to use
Pipe cleaner.Wax spatula or paraffin cutting hook wipe the paraffin deposited on tube wall off, and this method has applied decades, in some oil fields
In using effect it is pretty good, but in some oil fields use when also expose the inadequate disadvantage of its wax removal amount.
Other than dewaxing method listed above, there are also some other dewaxing methods such as chemical exothermal method, electrical heating method and
Ultrasonic wave wax removal method and biological wax removal method that newly-developed gets up etc..A kind of wax control in Petroleum Production provided by the invention
Paraffin removal equipment work efficiency is high, easy to operate, wax removal is thorough, environmental-friendly, is suitable for a variety of wax removal scenes, and do not generate two
Secondary pollution.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of wax control paraffin removal equipment in Petroleum Production.
The present invention is realized with following technical solution:
A kind of wax control paraffin removal equipment in Petroleum Production, the equipment includes control room, master control borad, rope socket, power supply
Module, first motor, shaft coupling, swivel head, the second motor, linear guides, slide unit, toolbox, end cap seal centering ring,
The inside of swivel head is arranged in liquid-supplying system, the liquid-supplying system, and the liquid-supplying system includes classification liquid storage
Room, the classification fluid reservoir include novel wax-proofing agent fluid reservoir, are provided with novel wax-proofing agent in the novel anti-wax liquor fluid reservoir,
The novel wax-proofing agent is biological source wax-proofing agent.
Further, the rope socket is located at the top of paraffin cleaner, and lower end is connect with the control room, and control room is hollow
Cylindrical structure, be internally provided with sequentially connected master control borad, power module, first motor and shaft coupling.The master control
Plate includes wireless transport module, and for transmitting with the signal of peripheral control unit, the power module is all electrical of paraffin cleaner
Power elements, the first motor are connect by shaft coupling with the swivel head, and the swivel head is hollow cylindrical structure,
It is internally provided with sequentially connected second motor and linear guides, and the second motor driven slide unit carries out on linear guides
It moves back and forth, the front end of swivel head is arranged in the end cap, for sealing the hollow chamber of swivel head.
Further, equally distributed one group of sealing centering ring is provided on the outer wall of the control room and swivel head,
It is sealed by being formed with pipeline, to establish pressure difference at paraffin cleaner both ends, to push paraffin cleaner in petroleum pipeline internal motion,
Simultaneously it is described sealing centering ring be also used to support paraffin cleaner and guarantee paraffin cleaner during the motion to neutrality.The cutter group
Part includes wax removal knife, connecting rod, spring, and the wax removal knife is connected on the outer wall of swivel head by revolute pair, the blade of wax removal knife
Middle section connects one end of connecting rod by revolute pair, and the other end of the connecting rod is connected on slide unit by revolute pair, in connecting rod
Between be provided with spring.
Further, the inside of swivel head, including classification fluid reservoir, the classification storage is arranged in the liquid-supplying system
Liquid chamber further includes novel except wax liquor fluid reservoir, micropump, the first solenoid valve block, first jet group, pipeline, second solenoid valve group,
