Abstract
The utility model relates to a multi-frequency vibrator under a pump, which comprises a joint 1, a variable wire 4, a vibrating plate 5, a lower tube 6, a vibrating valve 7, a liquid inlet pipe 8, etc. The multi-frequency vibrator is characterized in that a tubular upper tube 3 is installed between the joint 1 and the variable wire 4, and the outer tube wall is provided with a cylindrical rubber valve 2. The utility model has the advantages of simple structure, easy manufacture and reliable operation. When the multi-frequency vibrator is used for block removal construction of an oil pumping well, the multi-frequency vibrator can convert main vibration waves which are generated by oil pipe columns and the vibration frequencies of which are lower than 20Hz and higher harmonic waves which are generated simultaneously into pulse waves which act on the stratum, and the purposes of efficient block removal and oil increase can be achieved.
Description
The utility model relates to a kind of oil field downhole tool, especially for multifrequency vibrator under the pump of pumpingh well.
Before the utility model, each oil field is for improving pumpingh well output, the oil well pumps that adopt are installed the self-vibration extracting device of oil down more, its principle is to utilize the flexible vibration wave that produces of tubing string in the manufacturing process, convert the vibratory impulse ripple to by the vibrating reed on the self-vibration extracting device of oil and act on the stratum, reach the purpose of plugging removal and stimulation; But owing to be subjected to the restriction of this class device frequency characteristic, in all vibration waves that produce on the tubing string, have only the part higher hamonic wave to convert impulse wave to by vibrating reed and obtain utilizing, the master of vibration frequency below the 20Hz ripple that shakes then can not be fully used, and has influenced the effect that de-plugging increases oil.
The purpose of this utility model is: for oil field pumping well production provides a kind of higher hamonic wave that produces can not only utilize tubing string flexible the time, and the ripple that the master of vibration frequency below 20Hz can also be shaken converts impulse wave, multifrequency vibrator under the high efficiency pump to.
The purpose of this utility model realizes by following measure: multifrequency vibrator under a kind of pump, comprise joint, change silk, vibrating reed, following pipe, vibrating valve, feed tube etc., it is characterized in that at joint and become be equipped with between the silk tubulose on pipe, columned glue valve also is housed on its outer tube wall.
The utility model is simple in structure, be easy to processing, reliable operation, when being used for pumpingh well de-plugging construction, ripple and the produced simultaneously higher hamonic wave of the master of vibration frequency below 20Hz that tubing string produces being shaken all converts impulse wave to, acts on the stratum and reaches the purpose that efficient de-plugging increases oil.
Fig. 1 is the structural representation of multifrequency vibrator under the pump.
Under the pump multifrequency vibrator by joint 1, glue valve 2, on manage 3, become silk 4, vibrating reed 5, manage 6 down, vibrating valve 7, feed tube 8 etc. form.Between joint 1 and the change silk 4 going up of a tubulose is installed and manages 3, columned glue valve 2 is housed on its outer tube wall; Be connected with down pipe 6, vibrating valve 7 and feed tube 8 in turn below the change silk 4, and on the outer wall of following pipe 6 a plurality of discoid vibrating reeds 5 be housed also.
The using method of multifrequency vibrator and operating principle are under the pump: it is loaded on oil well pump lower end and G.I.H by joint 1, changed by its inner head of liquid and flexible when producing vibration when tubing string in the manufacturing process, because the piston effect that cooperates between glue valve 2 and the sleeve pipe, the master of its vibration frequency below the 20Hz ripple that shakes can be converted to low frequency pulse wave by glue valve 2 and discharges, the above higher hamonic wave of its produced simultaneously 20Hz then still is converted to the high-frequency impulse ripple and discharges by managing vibrating reed 5 on 6 down, thereby the vibration wave that tubing string is produced is fully used, and has improved the vibrator de-plugging and has increased oily ability.
