Abstract
An autooscillation oil extraction device for an oil field pumping well is characterized in that an upper check valve (1) and a lower check valve (5) are respectively installed at the upper part and the lower part of the inner side of a central tube in which a plurality of vibrating reeds (6) are arranged, and a hydraulic cylinder (2), a rubber barrel (3) and a shear pin (4) are sequentially installed at the upper part of the outer wall of the central tube. The autooscillation oil extraction device has a simple structure, is convenient to use, and can utilize the vibrating reeds (6) on the central tube to generate high frequency short amplitude vibration waves for acting on the stratum during negative pressure oil extraction of an oil-water well or pumping production, so the production increasing effect can be improved.
Description
Technical field: the utility model relates to a kind of oil field downhole tool, especially for a kind of oil field pumping well self-vibration extracting device of oil that recovers the oil.
Background technology: before the utility model; Mostly the used negative pressure extracting device of oil of each oilfield is pumping packer type structure; Can produce stronger suction function and certain long amplitude vibration ripple of low frequency to the stratum in the construction, but can not produce the short amplitude vibration ripple of high frequency, thereby influence construction effect.
Summary of the invention: the purpose of the utility model is: for negative pressure production provides a kind of oil field pumping well self-vibration extracting device of oil; Because this device central tube bottom is equipped with the vibrating reed of a plurality of ring-types; When negative pressure production is constructed or open and take out in the production; The short amplitude vibration ripple of high frequency can be produced, thereby effect of increasing production can be improved.
The purpose of the utility model realizes through following measure: a kind of oil field pumping well self-vibration extracting device of oil; Comprise ball-and-seat, fluid cylinder, packing element, shear pin, following ball-and-seat; It is characterized in that the outer wall bottom is equipped with in the central tube of vibrating reed of a plurality of ring-types; Ball-and-seat is installed on top, ball-and-seat is down installed in the bottom, and its outer wall top is equipped with fluid cylinder, packing element and shear pin successively.
The utility model is simple in structure, easy to use, is used for the oil-water well negative pressure production or opens and take out when producing, and can produce the short amplitude vibration ripple of high frequency through the vibrating reed of central tube outer wall bottom ring-type, thereby can improve effect of increasing production.
Description of drawings: Fig. 1 is the structural representation of oil field pumping well self-vibration extracting device of oil.
The specific embodiment: oil field pumping well self-vibration extracting device of oil; Its structure is equipped with for the outer wall bottom in the central tube of vibrating reed 6 of 2-8 ring-type; Ball-and-seat 1 is installed on top, ball-and-seat 5 is down installed in the bottom, and its outer wall top is equipped with fluid cylinder 2, packing element 3 and shear pin 4 successively.The operating principle of oil field pumping well self-vibration extracting device of oil with method for using is: earlier through on the central tube this device being connected with pumping pipe string and down to the precalculated position, down-hole; Again through pressurization in the pumping pipe string; Fluid cylinder 2 descending compression packing elements 3 are expanded and locking; This moment, just but the put-on and delegated pumping pipe string carried out negative pressure production construction, or was lowered to deep well pump and opens and take out production.When pumping pipe string is up in the negative pressure production; Under the effect of last ball-and-seat 1 and following ball-and-seat 5; Can make the pumping pipe string stretching and produce the short amplitude vibration of a certain amount of high frequency; Then can convert the short amplitude vibration ripple of high frequency into and act on the stratum, thereby improve effect of increasing production through the vibrating reed on the central tube 6; When opening when taking out that pumping pipe string is wriggled up and down in the production; And when being locked in packing element 3 on the pit shaft, fluid cylinder 2 collisions; Also all can produce the short amplitude vibration of a certain amount of high frequency, can convert the short amplitude vibration ripple of high frequency into through the vibrating reed on the central tube 6 equally and act on the stratum.Construction is accomplished in the time of maybe need tripping out pumping pipe string, can make fluid cylinder 2 continue the descending shear pin 4 of cutting off again through the pumping pipe string pressurization, and packing element 3 decompressions are shunk.
