Abstract
The invention provides a deep-well pump sand plugging eliminating method and device of a pumping well, and belongs to the technical field of oil field exploitation retrieval. A plunger of the pumping well is lifted out of a pump cylinder through a 16-ton crane, so that the plunger moves up and down in an oil tube on the upper portion of the pump cylinder for 15-30 times, and silt on the surface of the plunger, especially the silt accumulated in a sand-prevention groove of the plunger, is washed away and shaken off through friction between the plunger and liquid; then the plunger is placed back into the pump cylinder and moves up and down for 10-15 times, silt attached to the inner surface of the pump cylinder is scraped through upward and backward moving of the plunger and stored in the sand-prevention groove of the plunger, then the plunger is lifted out of the pump cylinder, the preceding steps are repeated, and finally the silt in gaps between the pump cylinder of the pumping pump and the plunger is cleaned away and sand plugging eliminating is achieved.
Description
Technical field
The releasing method and the release device that the present invention relates to a kind of pumping well deep-well pump sand card, belong to oilfield exploitation retrieval technique field.
Background technique
At present, after oilfield exploitation deep-well pump is gone into the well, there is sand card, in the time of can not normally producing, how by terrestrial operation, to realize unfreezing, recover oil well production, for the water-sensitive oil reservoir that shakes out, reservoir rock is met after secondary water immersion, clay swelling, sand production in oil is more violent, conventional water well-flushing is removed pump chucking method, can only be to have washed oil well pump and the formation rock that is spoilt, the fluid sand-carrying amount flowing out from oil reservoir is like this larger, more muddyly can't bear, these fluids fall pump card again after entering pump very soon, can't resolve the object of removing oil well pump sand card at all, further cause on the contrary oil reservoir state deteriorating, sand production in oil situation is more aggravated.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of releasing method and release device of pumping well deep-well pump sand card, be applicable to oil field deep well plunger pump when down-hole generation sand card, the releasing method of practical.
A releasing method for pumping well deep-well pump sand card, contains following steps;
The basic reason of the oil well pump sand card result that to be sand grains assemble in pump barrel and plunger gap, gets rid of the silt particle here and gathers and be only the basic of oil well pump unfreezing.
Utilize 16 tons of cranes that oil pump plunger piston is proposed to pump barrel, plunger is twitched up and down in the oil pipe of pump barrel top, twitch up and down 15-30 remaining time, by the friction of plunger and liquid, wash away, shake off the silt particle of plunger surface (being particularly gathered in the anti-sand launder of plunger).
And then plunger is put back to pump barrel, twitch up and down 10-15 remaining time, by moving up and down of plunger, the silt particle that pump barrel internal surface is adhered to is wiped off, is stored in the anti-sand launder of plunger, then plunger is proposed to pump barrel, repeat above process, finally remove the silt particle in oil pump sleeve and plunger gap, separate desanding card.
A release device for pumping well deep-well pump sand card, sucker rod connects plunger; The bottom of plunger connects traveling valve; The bottom of pump barrel is connected and fixed valve, and sucker rod is put into oil pipe; The bottom of oil pipe connects pump barrel.
Advantage of the present invention is to adopt this method releasing oil well pump sand card cost low, effective, has made up prior art and has existed flushing fluid to damage the deficiency of oil reservoir, and in North China, water-sensitive sand well using effect is better.Unfreezing success rate 100%.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the present invention and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide a further understanding of the present invention, form a part of the present invention, schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention, as schemed wherein:
Fig. 1 is structural representation of the present invention.
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present invention belong to protection scope of the present invention.
Embodiment 1:
A releasing method for pumping well deep-well pump sand card, contains following steps;
The basic reason of oil well pump sand card is the result that sand grains is assembled in pump barrel 5 and plunger 3 gaps, and eliminating the silt particle here gathers and is only the basic of oil well pump unfreezing.
Utilize 16 tons of cranes to drive oil pump plunger piston 3 to propose pump barrel 5 sucker rod in oil pipe 12, plunger 3 is twitched up and down in pump barrel 5 top oil pipes, twitch up and down 15-30 remaining time, friction by plunger 3 with liquid, wash away, shake off the silt particle of plunger 3 surfaces (being particularly gathered in the anti-sand launder of plunger), the bottom of pump barrel 5 is standing valve 6, and the bottom of plunger 3 is traveling valve 4.
And then plunger 3 is put back to pump barrel 5, twitch up and down 10-15 remaining time, by moving up and down of plunger 3, the silt particle that pump barrel 5 internal surfaces are adhered to is wiped off, be stored in the anti-sand launder of plunger, then plunger 3 is proposed to pump barrel 5, repeat above process, the final silt particle of removing oil pump sleeve and plunger gap, separates desanding card.
A release device for pumping well deep-well pump sand card, sucker rod 2 connects plunger 3; The bottom of plunger 3 connects traveling valve 4; The bottom of pump barrel 5 is connected and fixed valve 6, and sucker rod 2 is put into oil pipe 1; The bottom of oil pipe 1 connects pump barrel 5.
As mentioned above, embodiments of the invention are explained, but as long as not departing from fact inventive point of the present invention and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection scope of the present invention.
