Well is more and more deeper, and sucker rod is more and more long, and its efficiency is lower, as current oil recovery urgent need to solve the problem.
The content of the invention
It is an object of the invention to provide one kind without the reciprocating flexible drawing oil pumping mechanism of bar, it can be avoided due to oil well too
It is deep, sucker rod is oversize and cause oil pumping system inefficiency.
It is of the present invention without bar reciprocating flexible drawing oil pumping mechanism, including oil well casing and the oil in oil well casing
Pipe and plunger displacement pump, the plunger displacement pump include pump barrel and plunger, are connected by connection sleeve pipe between oil pipe and pump barrel, also including first
Pull rope, the second pull rope and fixed pulley.The upper end of first pull rope is connected with the first drive mechanism, the first pull rope
Lower end is connected with the upper end of the first slip optical axis, and the first slip optical axis is slided with the first slip optical axis sealing shroud being arranged on oil pipe
It is dynamic to coordinate.The first check valve is provided with the connection sleeve pipe, the second slip optical axis is provided with the valve seat of the first check valve
Sealing shroud, is provided with the second slip optical axis being slidably matched therewith in the second slip optical axis sealing shroud, second slides optical axis upper end
It is connected with the first slip optical axis lower end by flexible strand or light weight beam；Second slip optical axis lower end is connected with its upper end.
The upper end of second pull rope is connected with the second drive mechanism, the bottom of the second pull rope and be located at plunger below determining
Pulley coordinates, and is connected with the bottom of plunger.
Further, first drive mechanism and the second drive mechanism are same mechanism, and it includes reel and drives reel
The actuating unit of reciprocating rotation, first pull rope is fixedly connected with reel, and is wrapped in one end of reel, the second pull rope
It is fixedly connected with reel, and is wrapped in the other end of reel, the winding direction of the first pull rope and the second pull rope is identical（It is i.e. equal
Wound according to clockwise or counterclockwise）, when moving spool turns, the first pull rope and the second pull rope synchronous backward
Motion.
Further, first check valve is non-return valve.
It is of the present invention without bar reciprocating flexible drawing oil pumping mechanism, due to said structure, increasing in connecting pipe box
One-way valve structures are added, pump oil have been carried out by the drive plunger displacement pump of first, second pull rope, instead of in the prior art by firm
Property sucker rod transmission energy, it is to avoid cause very much sucker rod oversize deeply due to oil well and cause oil pumping system inefficiency.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is connection sleeve pipe transverse cross in the present invention.
Specific embodiment
In order to technical scheme is explained further, come that the present invention will be described in detail below in conjunction with the accompanying drawings.
Participate in shown in Fig. 1, this without bar reciprocating flexible drawing oil pumping mechanism, including the first pull rope 3, the second pull rope 2,
Fixed pulley, oil well casing 7 and the oil pipe in oil well casing 78 and plunger displacement pump, the plunger displacement pump include pump barrel 14 and plunger
15, connected by connection sleeve pipe 9 between oil pipe 8 and pump barrel 14.
The upper end of first pull rope 3 is connected with the first drive mechanism, and light is slided in the lower end of the first pull rope 3 with first
The upper end connection of axle 4, the first slip optical axis 4 is slidably matched with the first slip optical axis sealing shroud 5 being arranged on oil pipe 8.It is described
The first check valve 11 is provided with connection sleeve pipe, the check valve uses non-return valve structure, on the valve seat of the first check valve 11
The second slip optical axis sealing shroud 13 is provided with, the second slip being slidably matched therewith is provided with the second slip optical axis sealing shroud 13
Optical axis 12, the second slip optical axis 12 upper end is connected by flexible strand 6 or light weight beam with the first slip optical axis 4 lower end；Second slides
The lower end of optical axis 12 is connected with the upper end of the plunger 15.The upper end of second pull rope 2 is connected with the second drive mechanism, and second leads
The bottom of messenger 2 coordinates with the fixed pulley 18 positioned at the lower section of plunger 15, and is connected with the bottom of plunger 15.The plunger is existing
There is technology, its structure is just not described in detail here.
First drive mechanism described in the present embodiment and the second drive mechanism are same mechanism, and it includes reel 1 and drives
The actuating unit of reel reciprocating rotation, first pull rope 3 is fixedly connected with reel, and is wrapped in one end of reel 1, second
Pull rope 2 is fixedly connected with reel, and is wrapped in the other end of reel, the winding direction phase of the first pull rope and the second pull rope
Together（Wound according to clockwise or counterclockwise）, when moving spool turns, the first pull rope and the second pull rope
Synchronous backward is moved, i.e., when spool turns, a rising, and another then declines.
Operation principle is as follows：
A, the first pull rope 3 rises, and pulling force slides optical axis 4, flexible strand 6, second and slides through first successively by the first pull rope 3 of restricting
Optical axis 12, plunger 15, realize lifting for plunger 15 so that be about to the second check valve 17 in plunger under the valve ball of the second check valve 17
Close, be about to the first check valve 11 on the valve ball of the first check valve 11 in connection sleeve pipe 9 and open, in pump barrel 14 and in oil pipe 8
Oil is pressed upward out, meanwhile, the oil of the lower section of pump barrel 14 enters pump barrel, and the second pull rope 2 is synchronous to be declined and moved with plunger 15.
B, the second pull rope 2 rises, and pulling force pulls downward on plunger 15 by the second pull rope 2 through fixed pulley 18, and second is unidirectional
Up second check valve 17 of valve ball of valve 17 is opened, and pump barrel lower end oil enters pump barrel upper end, meanwhile, first is single in connection sleeve pipe
It is about to the first check valve 11 under valve ball to valve 11 to close, oil is enclosed in oil pipe.
C, so far, completes a working cycles.
