Abstract
The invention relates to a well head crude oil cleaning device for well workover, which comprises a flared pipe made of metal, and is characterized in that a hydraulic cleaning module and an overflow opening are arranged on the flared pipe; at least one level of jet type water courses is formed on the hydraulic cleaning module; each level of jet type water courses is annularly distributed on the internal side of the hydraulic cleaning module; an angle-adjustable included angle is formed between the jet type water courses and the flared pipe body; and the hydraulic cleaning module is connected with a booster pump through a connection pipe. The device has the advantages that about 1/2 well cleaning and killing time can be shortened, well cleaning operation efficiency can be improved, external wall of a production pipe can be completely cleaned, and leakage amount of well workover liquid and damage to reservoir can be reduced, oil drops can be prevented from blowing into the sea, and environment-friendly effect is good. In addition, with the adoption of the device, no diesel oil or well flushing fluid is required to dip and clean a well, therefore, operation cost can be effectively saved, operation drainage period can be shortened, and productivity can be returned to a level before operation faster.
Description
Technical field
The invention belongs to oil well well workover cleaning equipment, particularly relate to a kind of well workover well head crude oil washing/COW device.
Background technology
Very high during the marine oil field well workover to environmental protection requirement, the flow string that trips out fully must be cleaned up before pulling out of hole.At present, the preceding cleaning to flow string of marine conventional well workover lift pipe string instead circulates in the down-hole by well-repairing work liquid and finishes.Conventional well workover was washed about needs of kill-job time two days, that have even reach tens days, wherein a part is washed the kill-job time and is absolutely necessary, and comprises kill-job time and the time that inner tubal wall is enough cleaned, this part operation generally can be finished in one day, and all the other times are pure duration of well flushing.Wash kill-job at present for a long time, can produce following drawback: 1, wash kill-job for a long time, miss greatlyyer, bigger pollution is caused on the stratum,, pollute even more seriously, reduced the ultimate recovery in oil field especially to water-sensitive formation.Though 2 have experienced the kill-job of washing of long period, a lot of heavy oil wells still can not clean up oil pipe, have increased the difficulty that makes a trip, and pollute the work-yard simultaneously.Greasy dirt can be walked about by personnel and be taken other place to, not only is difficult to reach the platform hygienic requirements, and has potential safety hazard.If make a trip when wind is arranged, the part oil droplet can descend slowly and lightly into the sea, causes the pollution to marine environment.3, a large amount of diesel oil of clean-out service consumption remove to soak oil pipe, even the well that has also need use flushing fluid, and expense is higher; In addition, the growth activity duration can cause expenses such as personnel, instrument, equipment leasing also many, and then has increased the clean-out service expense.4, all need to experience one section drainage period after the operation, can return to the production capacity level before the operation after longer a period of time of oil well production, have in addition can't return to production capacity before the operation again.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, can effectively save washing and cleaning operation time and expense and can improve the well workover well head crude oil washing/COW device of environment protecting.
Mentality of designing of the present invention is: for general stratum energy is not very high oil well, generally speaking through realizing kill-job about two circulating cycles, because the oil pipe internal volume is little, rate of flow of fluid is fast, and the tube inner wall clean-up performance can satisfy and pounds gate gurgle valve or drag for the stifled requirement of Y after two circulating cycles.In this case, save the pure duration of well flushing of part in traditional duration of well flushing, change oil-pipe external wall into,, be implemented in the function that well head cleans the tubing string outer tube wall when pulling out of hole promptly by instrument provided by the present invention in the operation of well head wash cycles.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
Well workover well head crude oil washing/COW device, the oviduct that comprises metal material, it is characterized in that: described oviduct is provided with waterpower cleaning module and overfall, at least be shaped on one-level on the described waterpower cleaning module and spray hydrophthalmia, described injection water eye thimble shape is distributed in waterpower cleaning module medial surface, spray the angle that is provided with adjustable angle between hydrophthalmia and the oviduct body, the waterpower cleaning module connects booster pump by tube connector.
The present invention can also adopt following technical scheme:
Be shaped on two-stage on the described waterpower cleaning module and spray hydrophthalmia.
Described waterpower cleaning module is arranged on the joint of the horn mouth and the cylinder straight tube outer wall of oviduct, and described waterpower cleaning module and oviduct are made as an overall structure.
Be fixed with removable waterpower cleaning module on the horn mouth inwall of described oviduct.
The angle that described two-stage is sprayed between hydrophthalmia and the oviduct body is between 20 ~ 80 °.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, spray at a high speed through the oblique below of injection hydrophthalmia on the waterpower cleaning module after utilizing this device to make well-repairing work liquid by the booster pump pressurization, the crude oil that the flow string that will trip out from the down-hole adheres to is rinsed well, soiling solution enters into slurry tank via the oviduct overfall subsequently, thereby reach former well flow string is cleaned on trip-out limit, limit at well head effect, must anti-circulation goes to the cleaning of part tubing string aboveground the present situation that down-hole string cleans up from the down-hole in the down-hole by flushing fluid when changing traditional marine oil field well workover.Like this, not only can improve clean-out service efficient with washing kill-job time shortening about 1/2nd, will produce pipe pipe outer wall and thoroughly clean up, but also can reduce the workover fluid wastage, alleviate reservoir damage, it is marine to avoid oil droplet to be blown into, and environment protecting is good.In addition, use this device to need not to soak well-flushing with diesel oil or flushing fluid, effectively save operating cost, shorten the operation drainage period, production capacity comparatively fast returns to the level before the operation.
