Abstract
The utility model relates to a kind of machine-pumped oil well snubbing serving wax removal and blowout hookup.When mainly solving existing producing well operation on R a T easily wax deposition, well liquid can from the problem of well head ejection.It is characterized in that: described tank entrance (7) is connected with inlet heater (6), tank outlet (8) place is connected with outlet heater (1), and tank outlet (8) is connected with positive displacement pump (10), described tank body (2) top is connected with vacuum pump (4).This machine-pumped oil well snubbing serving wax removal and blowout hookup effectively can remove the attachments such as wax on sucker rod, oil pipe and dead oil on the one hand, and can prevent the crude oil when playing lower tubular column from spraying from well.
Description
Technical field
The utility model relates to oilfield, the wax removal specifically during a kind of producing well no killing well environmental protection operation and blowout hookup.
Background technology
Oil field machinery oil well, in oil recovery process, needs often to carry out maintainability and removes flow string operation.When carrying out removing flow string operation, the wax in well and dead oil can attach and on R a T, be brought to ground, to environment.At present to attachments such as the wax on sucker rod, oil pipe and dead oils, be generally clean at ground steam, but certain environment pollution can be caused.Meanwhile, because strata pressure is large, the well liquid in well can spray from pit shaft, causes environment pollution, and brings difficulty to the construction operation of workman, greatly affects job execution progress, quality and safety.At present for preventing crude oil from spraying from pit shaft, generally all adopting mud to carry out kill job, so not only can cause mud contamination oil reservoir, affect crude oil production, and also can cause environment pollution after mud tubing flow displacement.
Summary of the invention
During in order to overcome existing producing well operation on R a T easily wax deposition, well liquid can from the deficiency of well head ejection, the utility model provides a kind of machine-pumped oil well snubbing serving wax removal and blowout hookup, this machine-pumped oil well snubbing serving wax removal and blowout hookup effectively can remove the attachments such as wax on sucker rod, oil pipe and dead oil on the one hand, and can prevent the crude oil when playing lower tubular column from spraying from well.
The technical solution of the utility model is: a kind of machine-pumped oil well snubbing serving wax removal and blowout hookup, comprise tank body, the two ends of described tank body are respectively equipped with tank entrance and tank outlet, the top of tank body has tank mouth, described tank entrance is connected with inlet heater, tank exit is connected with outlet heater, and tank outlet is connected with positive displacement pump, and described tank body top is connected with vacuum pump.
Described vacuum pump is connected with vaccum pump motor, and positive displacement pump is connected with positive displacement pump motor.
The utility model has following beneficial effect: owing to taking such scheme, the tank entrance of tank body and tank outlet connect heater respectively, liquid in tank body can be heated, and by tank entrance and tank outlet being connect respectively the diverse location of well head, this device can realize the object heating well-washing wax-cleaning and prevent crude oil from spraying from flow string respectively.Compared with existing wax removal and blowout hookup, this apparatus structure is simple, easy for installation, wax removal and blowout prevention effective, avoid environment pollution.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1, Fig. 2, a kind of machine-pumped oil well snubbing serving wax removal and blowout hookup, comprise tank body 2, the two ends of described tank body 2 are respectively equipped with tank entrance 7 and tank outlet 8, and the top of tank body 2 has tank mouth 5, and described tank entrance 7 is connected with inlet heater 6, tank exports 8 places and is connected with outlet heater 1, and tank outlet 8 is connected with positive displacement pump 10, positive displacement pump 10 is connected with positive displacement pump motor 11, and positive displacement pump 10 is provided with positive displacement pump outlet 12.Described tank body 2 top is connected with vacuum pump 4, and vacuum pump 4 is connected with vaccum pump motor 3.Above-mentioned inlet heater 6, outlet heater 1, positive displacement pump motor 11, vaccum pump motor 3 are powered by switchbox 9.
This device and sleeve pipe is self-styled supports the use, its operating principle is as follows: when machine-pumped oil well needs to carry out workover treatment, first oil well watering is received on tank entrance 7, again positive displacement pump outlet 12 is connected on the oil jacket annular space of oil well, the oil-out of oil well is connected to tank mouth 5, and is connected by the power supply of switchbox 9 by electrician.After checking that all connection work are intact, safe, open oil well watering valve, add water in tank; Open inlet heater 6 simultaneously, the water entered in tank is heated, after reaching certain water level in tank, open the valve of the oil jacket annular space of oil well, the oil jacket annular space to oil well adds hot water, opens outlet heater 1 simultaneously, and start positive displacement pump 10, carry out well-washing wax-cleaning.When oil well oil-out has liquid to flow out, and when having certain liquid height in tank, close water mixing valve, the water in tank carries out circulating-heating well-washing wax-cleaning through oil jacket annular space after the heating.While well-washing wax-cleaning, note the temperature measuring oil well oil-out liquid, after the temperature of oil well oil-out liquid exceedes the temperature required for molten wax, recycling termination of pumping after 29 minutes.Then oil well oil-out is connected on the oil return pipeline of oil well, again starts positive displacement pump 10, the wax washed is discharged.At this therebetween, when water level is lower in tank, open water mixing valve, make to keep certain water level in tank, after the oil in oil well, wax all replace to clear water, hot-washing wax remover end-of-job.
When having carried out lower tubular column operation, tank entrance 7 is connected on the oil jacket annular space of oil well, then positive displacement pump outlet 12 has been connected on the oil return pipeline of oil well, shut tank mouth 6; The sleeve pipe of oil well is installed self-styled, after checking that all connection work are intact, safe, open the valve of oil jacket annular space and oil return pipeline; According to the height situation of liquid level, start or close positive displacement pump 10 and vacuum pump 4, namely start positive displacement pump 10 when liquid level is very high and close vacuum pump 4, when liquid level is very low, close positive displacement pump 10 and also start vacuum pump 4, when liquid level not high not low time, start positive displacement pump 10 and vacuum pump 4 simultaneously.The liquid level of oil well oil jacket annular space and pressure can be made like this to reduce, thus make to remove and do not have crude oil in the process of flow string and spray from flow string.
So this device can remove the attachment such as wax and dead oil on sucker rod, oil pipe effectively; And prevent crude oil when playing lower tubular column, spray from well, realize the object of machine-pumped oil well no killing well environmental protection operation.
