Abstract
The utility model relates to a pumping well is vibration protector in pit for stifled and protection is separated to pumping well oil reservoir comprises connector 1, sealer 2, oil pipe 3, trembler 4, vibration valve 5 and screen pipe 6. The device is novel in design, simple in structure, can be used with the cooperation of oil pumping tubular column and oil-well pump, and construction convenience. The device is suitable for large range of stratum conditions, generates oscillation without other external power sources, and can obtain dual effects of plugging removal and yield increase of an oil layer and oil layer protection.
Description
The utility model relates to a kind of downhole hardware that is used for pumpingh well oil layer unblocking and protection.
In the pumpingh well manufacturing process, down-hole fluid column load alternately shifts between tubing string and rod string in upper and lower stroke mutually, makes tubing string periodically increment of load and off-load.The liquid load of tubing string intercycle variation excites tubing string to produce vibration; though vibrating, this kind help oil layer unblocking; but owing to lack at present the protective device that to this kind vibration brings adverse consequences; thereby often cause adverse effect and troubles such as oil well pump loss of plunger stroke, pumpingh well pump efficiency and output are affected.
The purpose of this utility model is to provide a kind of vibration realizing vibration that both can effectively utilize tubing string to remove oil layer blocking, can play again to eliminate or alleviate and vibrate the pumpingh well down-hole vibration protector that causes adverse consequences and oil layer protection effect.
The utility model is to realize like this.This device is made up of connector, oil pipe, sealer, vibrating reed, vibrating valve and screen casing, its structure, assembled relation are as follows: the vibrating valve upper and lower is respectively with oil pipe and the screen casing of being threaded, oil pipe top is set with sealer, the bottom is set with vibrating reed, and the upper end is with the connector that has been threaded.During use, this device is assembled in the pumping pipe string lower end, and thereupon down to the oil reservoir middle part.Under pumpingh well ordinary production situation, this device changes the longitudinal elasticity vibration of tubing string into the lateral pressure fluctuation, vibrating valve wherein produces frequency under the effect of tubing string elastic telescopic be the high strong shock wave of 0.1-0.15Hz, vibrating reed produces multiple frequency vibration ripple under tubing string elastic vibration excitation, removing oil reservoir duct, near wellbore zone stops up, improve the rerum natura and the fluidised form of formation fluid, quicken crude stream, thereby realize oil well production increasing to the shaft bottom.Simultaneously, sealer then can make the oil reservoir top seal, prevents that the liquid of oil casing annular space from entering oil reservoir, prevents that the oil reservoir secondary pollution from promptly protecting the effect of oil reservoir thereby play.
The utility model modern design, simple in structure, can be used with pumping pipe string and oil well pump, easy construction, and reusable.It is bigger that this device is suitable for the formation condition scope, and producing vibration does not need other external power source.Utilize this device can obtain the double effects of oil layer unblocking volume increase and oil layer protection, be suitable for extensive employing.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
As shown in the figure, the utility model is made up of connector 1, sealer 2, oil pipe 3, vibrating reed 4, vibrating valve 5 and screen casing 6.Wherein, vibrating reed 4 is the glass stria tube that a usefulness spring steel is made.Vibrating valve 5 can adopt the standing valve of oil well pump.Oil pipe 3 upper and lower ends are respectively equipped with pin thread, and the top tube wall is provided with 4 circular holes that are uniformly distributed along the circumference.Sealer 2 is the cylinder that a usefulness rubber is made.
Claims (2)
1, a kind of pumpingh well down-hole vibration protector; form by connector (1), sealer (2), oil pipe (3), vibrating reed (4), vibrating valve (5) and screen casing (6); it is characterized in that; vibrating valve (5) upper and lower is respectively with oil pipe that has been threaded (3) and screen casing (6); oil pipe (3) top is set with sealer (2); the bottom is set with vibrating reed (4), and the upper end is with the connector that has been threaded (1).
