Abstract
The invention belongs to the technical field of cleaning wax oil of oil pipes and discloses a method for cleaning and recovering wax oil of oil pipes, and special thermal washing wax oil removing pipes capable of being disassembled and assembled conveniently. The method is mainly and technically characterized by comprising the following steps of: connecting the ends of the oil pipes to be washed in series by using the thermal washing wax oil removing pipes capable of being disassembled and assembled conveniently, continuously inputting liquid at the temperature of between 90 and 120 DEG C and under the pressure of 3.5 Mpa into the oil pipes by using a hot liquid pump at the front end of the oil pipe for 2.5 to 3.5 hours to ensure that the temperature of liquid in the oil pipes can reach 90 to 95 DEG C, and purifying and recovering the wax oil which is obtained through washing by using a wax oil recovery tank. Therefore, after being recovered by the recovery tank, the wax oil which is obtained through washing can also be reused; compared with the conventional cleaning method, the method has the advantages of avoiding environmental pollution and waste of the wax oil, along with low working intensity and high cleaning efficiency; and the wax oil can be washed completely.
Description
Technical field
The invention belongs to hot-washing wax remover oil tech field, relate to a kind of oil pipe wax oil concretely and clean the method and the special-purpose easy-to-mount hot-washing wax remover oil pipe of this method that reclaims.
Background technology
The oil pipe of oil well in use forms wax oil at the tube inner wall face easily, reduces oil pump capacity, needs regularly or aperiodically oil pipe to be cleaned.Clean oil pipe at present and mainly adopt boiler car that the thermal source steam is provided, utilize thorn bayonet washing oil inside pipe wall to carry out wax removal.There is following drawback in this method: one of which, and the wax oil after the cleaning can not reclaim, and causes the waste of wax oil; Its two, splashing that boiler car thorn rifle wax removal causes can cause the pollution of surrounding area air and soil, makes the peripheral farmland pollution of oil well, causes damage to the peasant, seriously restricted oil field operation production; Its three, working strength is big, cleaning efficiency is low; The conventional boiler wax removal is wasted time and energy; Especially it is lower, uneconomical to clear up the serious well efficient of wax deposition, continuous manual work thorn rifle wax removal more than 20 hours often occurs, and expense is higher; The more important thing is to have prolonged the duration, because of the wax removal overlong time seriously delays production; Its four, if cleaned directly into well, some are because doing over again of causing of the problem oil pipe G.I.Hs that can't find of naked eyes.
Summary of the invention
First technical problem that the present invention solves just provides that wax oil a kind of the cleaning under is recyclable, environmentally safe, working strength is little, cleaning efficiency is high, clean up thoroughly, can in time find that the oil pipe wax oil of oil pipe defective cleans the method for recovery.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
This method comprises the following steps:
The first step is with the oil pipe serial connection of discharging
Oil pipe discharging with needs clean is serially connected through easy-to-mount hot-washing wax remover oil pipe oil pipe end with it;
In second step, be communicated with hot liquid pump and recycling can
The oil pipe front end that is serially connected is connected with the hot liquid pump, and its end is communicated with the wax oil recycling can;
In the 3rd step, the input hot liquid cleans oil pipe
Through hot liquid pump input temp in oil pipe is 90-120 ℃, and pressure is the liquid of 3.5 MPas, makes that the fluid temperature in the oil pipe reaches 90 ℃-95 ℃, imports 2.5-3.5 hours continuously;
In the 4th step, reclaim the wax oil in the recycling can
Through cool-down method the wax oil in the recycling can is solidified, purify then and reclaim;
The 5th step, the oil pipe that obtains cleaning
Easy-to-mount hot-washing wax remover oil pipe is taken off the oil pipe that can obtain cleaning.
Its additional technical feature is:
After said the 3rd step input hot liquid cleaning oil pipe finishes, the hot liquid pump is taken off hydraulic test pump on the oil pipe front end that is serially connected connects; In oil pipe, feed the liquid of 9-10 MPas, oil pipe is carried out pressure testing, damage as finding; The oil pipe that damages is taken off, continue pressure testing;
Cleaning in the oil pipe step at said the 3rd step input hot liquid, is 105-110 ℃ through hot liquid pump input temp in oil pipe, and pressure is the liquid of 3.5 MPas, makes that the fluid temperature in the oil pipe reaches 92 ℃-93 ℃, imports 2.8-3.0 hours continuously.
Oil pipe wax oil provided by the invention cleans the method that reclaims, and comparing with prior art has the following advantages: one of which, because this method comprises the following steps:
The first step is with the oil pipe serial connection of discharging
Oil pipe discharging with needs clean is serially connected through easy-to-mount hot-washing wax remover oil pipe oil pipe end with it;
In second step, be communicated with hot liquid pump and recycling can
The oil pipe front end that is serially connected is connected with the hot liquid pump, and its end is communicated with the wax oil recycling can;
In the 3rd step, the input hot liquid cleans oil pipe
Through hot liquid pump input temp in oil pipe is 90-120 ℃, and pressure is the liquid of 3.5 MPas, makes that the fluid temperature in the oil pipe reaches 90 ℃-95 ℃, imports 2.5-3.5 hours continuously;
In the 4th step, reclaim the wax oil in the recycling can
Through cool-down method the wax oil in the recycling can is solidified, purify then and reclaim;
The 5th step, the oil pipe that obtains cleaning
Easy-to-mount hot-washing wax remover oil pipe is taken off the oil pipe that can obtain cleaning;
Like this, be cleaned the wax oil that gets off and after recycling can reclaims, can also utilizing, not only do not resemble existing cleaning method environment is polluted, also prevented the waste of wax oil, advantage such as have that working strength is little, cleaning efficiency is high, clean up thoroughly;
Its two owing to after said the 3rd step input hot liquid cleans oil pipe and finishes, the hot liquid pump is taken off; Hydraulic test pump on the oil pipe front end that is serially connected connects feeds the liquid of 9-10 MPas in oil pipe, oil pipe is carried out pressure testing; As find to damage, the oil pipe that damages is taken off, continue pressure testing; Through pressure testing, the defective oil pipe that some are invisible to the naked eye is chosen, and does over again again after having avoided going into the well.
Second technical problem that the present invention solves just provides a kind of above-mentioned oil pipe wax oil and cleans the easy-to-mount hot-washing wax remover oil pipe that the serial connection oil pipe is used in the method that reclaims.
For solving the problems of the technologies described above; The technical scheme that the present invention proposes is: comprise body and the joint that is positioned at these body two ends; Said joint comprises the head of accepting that has internal thread, being provided with annular recess near the joint side away from a side of accepting head, is provided with at said body two ends and accepts sleeve pipe; The said headband of accepting has an end of annular recess to insert described accepting in the sleeve pipe; Accept end to end said that portion and said accepting are provided with sealing mat between the sleeve pipe, be provided with this in said side of accepting sleeve pipe and accept the eccentric fixture block that the casing wall pin is connected, this off-centre fixture block is stuck in the described annular recess.
