Description
Technical field
The present invention relates to petroleum drilling and mining workover rig fields, are related specifically to cementing truck pipeline-cleaning process.
Background technique
Casing and cementing is the project of vital and lasting importance in oil field, and it is oil field that the quality of cementing quality, which is related to the exploitation and construction in oil field,
The foundation engineering of long term stable production.By visiting investigation to major oil field equipment user, comprehensive current Domestic Environment protection is required
With clean-in-place regimen condition, existing cleaning process is analyzed, summarizing existing procedure, that there are problems is as follows:
(1) equipment cleaning process is indefinite, and there is some difference for each well cementation team's cleaning process, redundancy, inefficient stream in cleaning process
Journey is generally existing.
(2) the densitometer cleaning process for lacking high efficient and reliable, cement agglomeration, residue retention etc. in densitometer after cleaning
There is presence when problem, influences densitometer service life and performance.
(3) increasingly harsh due to Law on Environmental Protection Laws & Regulations, scene is fewer and fewer for cementing equipment cleaning water consumption,
Equipment cleaning difficulty increases.
Summary of the invention
It is an object of the invention to: a kind of cleaning process of cementing truck pipeline is provided, using pipeline segmentation cleaning, densitometer
The methods of huge discharge flushing, solution cleaning water consumption is big, cleaning efficiency is low, densitometer and mixer clean the problems such as being not thorough.
To achieve the above object, the technical solution of the present invention is as follows:
A kind of cementing truck pipeline-cleaning process, characterized by the following steps: the previous cleaning stage, one cycle wash phase,
Secondary cycle wash phase, three times wash cycles stage, blowdown；
The previous cleaning stage: first wash is carried out using clear water to densitometer, mixer, flowmeter, jet pump and circulating pump etc..Pass through
The high flow rate clear water with pressure that centrifugal pump generates will all bring slurry mixing tank into pipeline and key components and parts for the cement slurry of agglomeration
In；
One cycle wash phase: emphasis tentatively cleans densitometer, mixer.It is opened by suitably switching pipe valve
It closes, and opens circulating pump, so that the previous cleaning stage is poured into the water in slurry mixing tank and iterative cycles flushing is carried out to densitometer and mixer.When
Ejected wash water color keep is stablized, and waste liquid is discharged without valve, opening plunger pump is suitably switched when increased significantly for impurities in water；
Secondary cycle wash phase: closed cycle pipeline is formed using slurry mixing tank-circulating pump-densitometer, to densitometer, slurry mixing tank
It is cleaned again.Firstly, opening circulating pump by suitably switching pipe valve switch and clear water in measuring tank being pressurized by close
Degree meter and mixer are pumped in slurry mixing tank, when there being certain water in slurry mixing tank, by suitably switching pipe valve switch,
Circulating pump is opened, water wash cycles densitometer and the mixer in slurry mixing tank are made, the purpose in this stage is to guarantee without larger dirt
Grain remains in densitometer and mixer；
Wash cycles stage three times: huge discharge cleaning is carried out to densitometer, mixer using original clear water emphasis, it is ensured that
It is remained inside it without cement slurry.Firstly, opening circulating pump by suitably switching pipe valve switch, making the clear water in measuring tank
Wash cycles densitometer, the purpose in this stage are to guarantee to remain in densitometer without the sewage after any cleaning；Secondly, passing through
Pipe valve switch is suitably switched, circulating pump is opened, makes the clear water in measuring tank, mixer is carried out most by circulating pump pressurization
Primary cleaning, waste water are discharged into slurry mixing tank afterwards；The purpose in this stage is to guarantee to remain on mixing without the sewage after any cleaning
In device；
Blowdown: equipment pipe valve is all closed, and is injected sewage in plunger pump by circulating pump, charge pump, finally by column
Plug pump pumps out sewage, completes final cleaning step.
Beneficial effects of the present invention: manifold cleaning process solves ineffective, cleaning in current cleaning process and needs water
Larger problem is measured, has formulated multistage cleaning program for the component of the easily residual cement slurry such as densitometer, mixer, it is ensured that
Densitometer, mixer cleaning effect.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Principles and features of the present invention are illustrated with reference to the accompanying drawing, the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
The previous cleaning stage
It is as shown in Fig. 1: densitometer 5, mixer 6, flowmeter 4, jet pump 9 and circulating pump 10 etc. will to be used in this stage clear
Water carries out first wash.8 bottom water supply valve of measuring tank is opened, and not used clear water passes through jet pump 9 and circulation in measuring tank 8
10 pressurization of pump, meter pipeline is sealed by 7 pipeline of measuring tank 8- circulating pump 10- densitometer 5- slurry mixing tank；Measuring tank 8- circulating pump
7 pipelines of 10- jet pump 9- mixer 6- slurry mixing tank, that is, mixer pipeline；Measuring tank 8- circulating pump 10- flowmeter 4- slurry mixing tank 7 is managed
Road, that is, flowmeter pipeline, is discharged into slurry mixing tank 7, and the valve of 7 bottom of slurry mixing tank is all closed at this time, passes through circulating pump 10 and injection
The high flow rate clear water with pressure that pump 9 generates, all brings the cement slurry not agglomerated in pipeline and key components and parts into slurry mixing tank 7
In, complete previous cleaning operation.
One cycle wash phase
This stage is tentatively cleaned emphasis to densitometer 5, mixer 6, the specific steps are as follows:
Other valves of pipeline are closed, 7 pipeline of slurry mixing tank 7- circulating pump 10- densitometer 5- slurry mixing tank and slurry mixing tank 7- mixing are opened
All valves of 7 pipeline of device 6- slurry mixing tank open circulating pump 10 using the previous cleaning stage and pour into the water in slurry mixing tank 7 to densitometer 5
Iterative cycles flushing is carried out with mixer 6；
The ejected wash water situation in slurry mixing tank 7 is observed, water color keep to be cleaned is stablized, and when impurities in water is without increased significantly, closes
7 pipeline of 7 pipeline of circulating pump 10- densitometer 5- slurry mixing tank and circulating pump 10- mixer 6- slurry mixing tank opens slurry mixing tank 7- circulating pump
