The further technical scheme of the present invention is, described volume increase fall back pressure device by beam hanger with produce that pump links to each other and the two can be with frequently moving up and down, described production pump comprises standing valve and the production pump travelling valve of producing pump.
The further technical scheme of the present invention is, the support leather cup of described interior pump barrel supports leather cup when entering on the supporting seat of outer pump barrel and may be stuck on the supporting seat, forms enclosure space between inside and outside pump barrel.
The further technical scheme of the present invention is, the piston that back pressure device falls in described volume increase is comprised of two different pistons of diameter.
Utilize the step-down of aforesaid equipment to increase oily method, it is characterized in that, comprise following steps:
Make up the enclosure space between the inside and outside pump; The support leather cup of pump barrel enters on the supporting seat of outer pump barrel in when carrying out down pump operation under the down-hole, and supporting leather cup can be stuck on the supporting seat, thereby forms enclosure space between inside and outside pump barrel;
The up process of beam hanger; When the oil pumper upstroke, producing the standing valve of pump opens, feed liquor is produced simultaneously the pump travelling valve and is shut uply, and the standing valve that back pressure device falls in volume increase is opened, feed liquor, the wander up and down valve that back pressure device falls in volume increase shuts up, is larger than production fluid amount in lower pump because the feed liquor amount of back pressure device falls in volume increase, produces the pump travelling valve and bears pressure less than or equal to 9mpa, be not lowered to supercharging device, reduce back pressure 9mpa;
The descending process of beam hanger; When down stroke, the standing valve of producing pump shuts, producing simultaneously the pump travelling valve opens descending, volume increase is fallen the back pressure device standing valve and is shut, volume increase is fallen the pressure that the supernatant liquid of back pressure device produces and can not exerted an influence to lower pump, increase production the wander up and down valve that falls back pressure product device and open, oil enters volume increase by inlet opening and falls back pressure product device, and lower pump bears pressure all the time less than or equal to 9mpa.
Falling the back pressure device practical function is to reduce the production back pressure of producing pump, reach the volume increase purpose, to utilize two-stage pump oil recovery principle, thereby the swabbing action of utilizing the middle part to fall back pressure device makes the back pressure of producing pump reduce half, thereby make to produce to bear and reduce half, the pump leakage amount is produced in reduction, reaches to increase oily purpose.
The piston that step-down increases oily device is comprised of two different large valve pistons of diameter, and the two nested inside, discharge capacity equal the difference of two-piston cross-sectional area and the product of oil well stroke.
Adopt as above the present invention of technical scheme, have following beneficial effect: this equipment adopts two-stage pump oil recovery imagination, and cost only needs about 3000 yuan, can reach the purpose of falling the back pressure volume increase, always under the condition less than or equal to 9mpa, work reduces back pressure greater than 9mpa to lower pump, successful.
