Abstract
The utility model relates to a two-layer separated production synchronous oil pumping device used in oil fields, which solves the difficult problem that pumping and production are separately carried out on two or more oil layers in the same time. The utility model is composed of a casing tube, a sieve tube, a pump body, a packer, and a hollow pump and is characterized in that an oil pumping pump plunger on the pump body is communicated with the lower end of the hollow pump plunger through a hollow rod arranged in an oil pipe. The utility model has the characteristic that pumping and production are separately carried out on two or more oil layers in the same time and guarantees that formation pressure doesn't interfere each other, and the crude oil production can be increased.
Description
The utility model relates to the oilfield machinery oil rig, belongs to double-layer separate and adopts the simultaneous pumping system device.
Oilfield machinery oil pumping at present relies on the horse head traction sucker rod on the pumping unit of ground to drive the oil well pump oil pumping.But meet two-layer above oil reservoir, can only exploit or close and adopt certain one deck oil respectively, can not distinguish extraction to two oil reservoirs or a plurality of oil reservoir simultaneously, influence oil output.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and provides a kind of double-layer separate that can carry out extraction respectively to two-layer or a plurality of oil reservoirs simultaneously to adopt the simultaneous pumping system device.
The purpose of this utility model is achieved through the following technical solutions: the oil pump plunger piston on the pump housing is by placing the lower end of the hollow stem connection hollow pump plunger in the oil pipe.
Above-mentioned hollow stem can have a plurality of to be communicated with a plurality of hollow pump plungers; Hollow pump plunger upper end can connect three-way valve.
The purpose of this utility model has following advantage than prior art: because the oil pump plunger piston on the pump housing makes the upper and lower oil reservoir of packet can distinguish extraction simultaneously by placing the lower end of the hollow stem connection hollow pump plunger in the oil pipe.
Accompanying drawing 1 is a structural drawing of the present utility model;
Accompanying drawing 2 is structural drawing of hollow pump;
Accompanying drawing 3 is structural drawing that original multilayer branch is adopted oil rig;
Accompanying drawing 4 is structural drawing of original commingling production oil rig.
To be further described the utility model below in conjunction with accompanying drawing:
Show by accompanying drawing 1, the oil rig of inserting in the underground bushing 2, oil well pump 4 lower ends are connected with screen casing 3, the plunger 10 that the plunger 5 of upper end is communicated with on the hollow pump 11 by the hollow stem 7 that places in the oil pipe 8, packet 6 is connected on the oil pipe 8 of 4 of hollow pump 11 and oil well pumps, plunger 10 upper ends of hollow pump 11 connect three-way valve 13, and sucker rod 14 connects horse head.
During actual the use, the plunger (5,10) that horse head traction sucker rod 14 drives on the interior pump of well moves up and down, and makes that the oil reservoir 1 interior crude oil under the packet 6 enters in the plunger 5 of oil well pump 4 by screen casing 3, enter along hollow stem 7 in the plunger 10 of hollow pump 11, flow in the oil pipe 8 by three-way valve 13; Crude oil in the oil reservoir 1 on the packet 6 enters in the cavity of hollow pump 11 by the following valve 9 of hollow pump 11, flows in the oil pipe 8 from last valve 12, arrives ground.As seen the crude oil of packet 6 upper and lower oil reservoirs 1 can be distinguished extraction simultaneously, and interlayer pressure does not disturb mutually.If oilfield exploitation needs, the hollow stem 7 of employing can have a plurality ofly distinguish extraction to be communicated with a plurality of hollow pump 11 plungers 10 to a plurality of oil reservoirs 1, the raising oil pumping yield.
