Abstract
The invention discloses a multi-drive mutually-balanced oil extractor. A bearing third wheel (1) is arranged above an oil wellhead, a driver (5) is arranged at the middle position of the distribution area of each oil wellhead, the main shaft of the driver (5) is provided with a driving wheel group (4), and a soft sucker rod (3) is used for connecting a downhole sucker rod with the driving wheel group (4); the main shaft of the driver (5) performs forward and reverse alternate rotation to drive the driving wheel group (4) arranged on the main shaft of the driver (5) to synchronously make forward and reverse rotation; and the balance between the forward and reverse torques of the main shaft of the drive (5) is achieved by adjusting the size of driving wheels on the driving wheel group (4) on the main shaft of the drive (5), and therefore the multi-drive self-balancing purpose is achieved. The multi-drive mutually-balanced oil extractor is elaborated by combining figures and embodiments. In the figures, the number 1 represents the bearing third wheel; the number 2 represents the connector of the downhole sucker rod group; the number 3 represents the soft sucker rod; the number 4 represents the driving wheel group; and the number 5 represents the drive.
Description
Affiliated technical field
The present invention relates to a kind of oil field machinery oil oil pumper, the mutual balanced oil extractor of especially many drivings.
Background technology
The oil field is centralized management in oil recovery process, be placed in ground through commonly used many oil pumpers are concentrated, and is called the platform well.
At present, known conventional pumping unit is an oil pumper and only carries out oil producing operation for a bite oil well, is the gravity such as balance oil well oil column, roofbolt in oil recovery process, and oil pumper need to have heavy balance weight to carry out balance, and complete machine weight is large; Simultaneously in order to obtain enough large consumption steel of stable complete machine overall dimensions; Simultaneously because oil pumper adopts steel polished rod suspention underground sucker rod group, so under the principle that guarantees its length of stroke, the complete machine height is higher, needs work high above the ground when workover treatment and oil pumper maintenance and repair, has potential safety hazard; Every oil pumper has independently motor, and power consumption is large.
Summary of the invention
For overcome oil pumper of existing oil pumper can only control a bite oil well, weight large, consume the deficiencies such as steel, power consumption are large, the invention provides a kind of soft lifting oil pumper of mutual balances that drives more.This oil pumper can drive simultaneously many mouthfuls of oil wells that are positioned at identical platform and carry out simultaneously oil producing operation; Utilize each oil well oil column and the mutual balance of roofbolt weight; Many mouthfuls of oil wells share a cover power, and power consumption is little, and the little consumption steel of floor space are few, adopt the software sucker rod to promote, and the complete machine height is low, the effect safe ready.
The technical solution adopted for the present invention to solve the technical problems is: the underground sucker rod group connection of each oil well is joined by underground sucker rod group connector of the present invention and software sucker rod, the driving wheels that the software sucker rod is walked around on supporting third wheel and the driver join, driver is positioned at each well head centre position, the supporting third wheel is positioned at each well head top, and makes the central lines of software sucker rod and well head center vertical direction; By adjusting each software sucker rod and the size that drives the driving wheel that wheels join, the moment of torsion that each oil well of two ends, the left and right sides is acted on the driver balances each other, and reaches the purposes that drive mutual balance more.The main shaft of driver can Double-directional rotary, so that the other end is transferred when carrying on the sucker rod of driver one end, the oil well condition of carrying end on this moment is in upstroke, transfers end and is in down stroke at oil well condition.The drive spindle direction of rotation changes when arriving maximum stroke length, realizes commutation, and the oil well at driver two ends operating mode of living in also occurs alternately so repeatedly, crude oil to be extracted into ground.
The invention has the beneficial effects as follows, only just can drive all oil well work that are positioned at a working platform on the ground with a driver, save a large amount of electric energy and steel.
Description of drawings
Accompanying drawing is one of embodiment of the present invention.
The present invention is further described below in conjunction with drawings and Examples.
1. supporting third wheels among the figure, 2. underground sucker rod group connector, 3. software sucker rod, 4. driving wheels, 5. driver.
The specific embodiment
In the drawings, supporting third wheel (1) is installed in the well mouth of oil well top, driver (5) is installed in the centre position of each well mouth of oil well distributed areas, a supporting of every mouthful of oil well third wheel (1), bogie wheel quantity is identical with oil well quantity during practical application, supporting third wheel (1) sum can be 2 to 15, when supporting third wheel (1) number is even number, divide equally in driver (5) both sides, when supporting third wheel (1) number was odd number, making driver (5) two ends distributed quantity difference was 1.Be equipped with on driver (5) main shaft and drive wheels (4), software sucker rod (3) is used for connecting downhole sucker rod group and drives wheels (4), and software sucker rod (3) is connected by underground sucker rod group connector (2) with the underground sucker rod group.Software sucker rod (3) is realized the direction location by driving wheels (4) when work, make software sucker rod (3) and the central lines of well head center at vertical direction; The forward and reverse alternate rotation of driver (5) main shaft, thus drive the synchronous forward and reverse rotation of driving wheels (4) that it is installed above; Make the forward and reverse torque phase balance of driver (5) main shaft by the size of adjusting the upper driving wheel of driving wheels (4) on driver (5) main shaft.Thereby reach the purposes that drive self-balancing more.
Claims (2)
1. drive mutual balanced oil extractor one kind more, supporting third wheel (1) is installed in the well mouth of oil well top, driver (5) is installed in the centre position of each well mouth of oil well distributed areas, be equipped with on driver (5) main shaft and drive wheels (4), software sucker rod (3) is used for connecting downhole sucker rod group and drives wheels (4), the forward and reverse alternate rotation of driver (5) main shaft, thus drive the synchronous forward and reverse rotation of driving wheels (4) that it is installed above; Make the forward and reverse torque phase balance of driver (5) main shaft by the size of adjusting the upper driving wheel of driving wheels (4) on driver (5) main shaft.
2. supporting third wheel according to claim 1 (1), bogie wheel quantity is identical with oil well quantity during practical application, supporting third wheel (1) sum can be 2 to 15, when supporting third wheel (1) number is even number, divide equally in driver (5) both sides, when supporting third wheel (1) number is odd number, make driver (5) two ends distributed quantity difference be no more than 2.
