Abstract

The utility model discloses a separate production and separate output oil pump which is suitable for oil wells needing separate zone production and separate zone metering and testing in mechanical oil production. The oil pump is composed of pump barrels (3), (9), plungers (4), (11), a traveling valve (12), a standing valve (13), etc. The lower part of an upper plunger (4) is provided with a lower plunger (11), and the two plungers are connected directly. The lower part of the pump barrel (3) is provided with the lower pump barrel (9), and the two pump barrels are connected by an extension tube (5) of the upper pump barrel. The outer part of the upper pump barrel (3) is provided with an outer tube (6), and a plurality of oil drainage valves (7) and oil inlet valves (8) are arranged at the connecting positions of the lower pump barrel (9) and the lower parts of the outer tube (6) and the extension tube (5) of the upper pump barrel. Well liquid on a lower oil layer is drained out of the ground surface by a hollow sucker rod (1), and well liquid on an upper oil layer is drained to the ground surface by the annular space of the outer tube (6) and the upper pump barrel (3) through the annular space of the hollow sucker rod (1) and an oil tube (2), so that the purposes of separate zone production, separate zone metering and separate zone testing are realized.

Description

Divide to adopt and tell oil well pump
Technical field:
The utility model relates to a kind of oil field and tells oil well pump with dividing to adopt, and need in the mechanical oil recovery to be specially adapted to the oil well of separate zone production, stratified stoichiometric test.
Background technique:
The oil well pump of the separate zone production of using mainly contains at present: double acting sucker rod pump, three effect oil well pumps, branch are taken out and are mixed out oil well pump etc., though these oil well pumps energy separate zone productions, but well liquid is discharged ground with the state that mixes, can't measure, test, analyze single oil reservoir, can not accurately judge each oil reservoir situation of down-hole, influence oil recovery manufacturing efficiency.
Summary of the invention:
The purpose of this utility model provide a kind of can separate zone production, extract the oil well pump of well liquid, stratified stoichiometric, zonal testing respectively.
The utility model is achieved in that this pump is mainly by pump barrel, plunger, standing valve, traveling valve, draining valve, compositions such as oiling valve, the upper plug lower end of this pump is connected to a lower plunger, a traveling valve is arranged at the lower plunger bottom, be connected to a following pump barrel below the last pump barrel, upper plug is the major diameter plunger, lower plunger is a small plunger diameter, last pump barrel is the major diameter pump barrel, following pump barrel is the minor diameter pump barrel, last lower plunger is a long-plunger, directly link, pump barrel is a short pump barrel up and down, is linked by the pump barrel extension pipe between the pump barrel up and down, and an outer tube is arranged outside last pump barrel, outer tube and last pump barrel extension pipe lower end are provided with a plurality of oiling valves and draining valve with the following pump barrel place of linking, and there is a standing valve following pump barrel extension pipe lower end.During use, last pump barrel and oil pipe join, upper plug and hollow rod join, sucker rod moves up and down and realizes oil well pump suction liquid function up and down, the well liquid of following oil reservoir is discharged ground by hollow stem, the well liquid of top oil reservoir is discharged ground by the annular space of hollow stem and oil pipe, thereby realizes the purpose of separate zone production, zonal testing, stratified stoichiometric.
The utility model since up and down pump formed two relatively independent for drainage system, can realize separate zone production, the function of discharge opeing metering separately, test can grasp the feed flow situation of oil reservoir up and down, at any time so that take measures to improve oilwell produced fluid amount.
Description of drawings:
Fig. 1 is the utility model structure principle chart
Embodiment:
The utility model is mainly by pump barrel (3) (9), plunger (4) (11), standing valve (13), traveling valve (12), draining valve (7), oiling valve compositions such as (8), a lower plunger (11) is arranged under the upper plug of this pump (4), two plungers directly link, there is a traveling valve (12) lower plunger (11) lower end, a following pump barrel (9) is arranged at last pump barrel (3) bottom, two pump barrels are linked by last pump barrel extension pipe (5), upper plug (4) is the major diameter plunger, lower plunger (11) is a small plunger diameter, last pump barrel (3) is the major diameter pump barrel, following pump barrel (9) is the minor diameter pump barrel, its upper plug (4), lower plunger (11) is a long-plunger, last pump barrel (3), following pump barrel (9) is a short pump barrel, a pump barrel extension pipe (5) (10) is respectively arranged at two pump barrel bottoms, an outer tube (6) is arranged outside last pump barrel (2), and outer tube (6) and last pump barrel extension pipe (5) lower end are provided with a plurality of oiling valves (7) and draining valve (8) with following pump barrel (9) connecting part, are provided with a traveling valve (13) in following pump barrel extension pipe (10) lower end.During oil well pump work, outer tube (6) links with oil pipe (2), upper plug (4) links with hollow rod (1), following pump barrel extension pipe (10) links with packet, pumping unit drives hollow rod (1) and moves up and down, last lower plunger (4) (11) is along with hollow rod (1) pumps, when last lower plunger (4) (11) is up, standing valve (13) and oiling valve (8) are opened, traveling valve (12) and expulsion valve (7) are closed, following pump barrel cavity (14), last pump barrel (3) increases with the formed toroidal cavity of lower plunger (11) (15) volume, pressure reduces, well liquid is just entered down in pump barrel cavity (14) and the last pump barrel cavity (16) by standing valve (13) and oiling valve (8), when upper plug (4), when lower prop cold (11) is descending, traveling valve (12) and expulsion valve (7) are opened, standing valve (13) and oiling valve (8) are closed, well liquid in the following pump barrel cavity (14) is discharged in the lower plunger (11), the well liquid of last pump barrel cavity (15) is discharged in pump barrel (3) and outer tube (6) and the toroidal cavity (16), finishes a suction oil process.Along with pumping unit works without cessation, lower plunger (4) (11) ceaselessly moves up and down in hollow rod (1) drive, thereby lower floor's well liquid is drained into ground by plunger (4) (11) endoporus, hollow rod (1), upper strata well liquid drains into ground by last pump barrel (3) and outer tube (6) toroidal cavity (16) annular space by oil pipe (2) and hollow rod (1), thereby realized the purpose of separate zone production, stratified stoichiometric, zonal testing.
