Abstract
The utility model discloses a linear underground oil pumping device. The linear underground oil pumping device comprises a ground driver, a driving cable, a linear underground oil pump, a linear underground reciprocating motor set, a sand control screen pipe, a sand control device, a driving cable underground contact, a motor protection cover, a cable fixing clamp, a well mouth fastener and the like. After the linear underground oil pumping device is powered on through the driving cable, the power of vertical reciprocation is generated under the action of the electromagnetic force to drive a plunger in the linear underground oil pump to move up and down, and the oil pumping process of the oil pump is finished. The linear underground oil pumping device can solve the technical problems that middle-yield and low-yield oil well oil pumping machines are large in lifting stroke loss, large in energy consumption, complex in structure, unreliable in performance, inconvenient to install and the like.
Description
Technical field
The utility model relates to a kind of oil field straight line downhole pumping installation.
Background technology
The oil pumper Lifting Technique is each field use of China mechanical oil recovery technology the most widely, the groundwork principle is that motor drives the reducer rotation by driving belt, reducer drives crank and connecting rod movement and walking beam is swung up and down, its flexible connecting member drives oil pumping polish rod with the variation of circular arc horse head pivot angle and moves, and reaches the purpose of drawing crude oil.
Traditional oil pumper shortcoming is: the intermediate transmission parts energy losses such as sucker rod are large, and energy consumption accounts for system 20%, and along with the intensification gradually that pump is hung, pipe side attrition of rod string phenomenon is on the rise, and in the exploitation of horizontal well, high angle hole, is overlapped the impact of the rake of tubes.
Summary of the invention
The purpose of this utility model is to provide a kind of straight line downhole pumping installation, with in solving, stripper well oil pumper lifting loss of plunger stroke is large, energy consumption is high, complex structure, performance is unreliable and the technical problems such as inconvenient are installed.
In order to realize the foregoing invention purpose,
A kind of straight line downhole pumping installation, mainly comprise the straight line downhole pump (3), sand control screen (5), sand control device (6), straight line underground reciprocating group of motors (4) and the motor protecting cover (8) that are connected in turn on oil pipe; Ground drives (1) is connected by driving cable down-hole connector 7 with straight line underground reciprocating group of motors (4); Straight line underground reciprocating group of motors (4) drives oil well pump (3) inner plunger reciprocating action.
Driving cable enters well head by well head fastener (11), by cable fixing clamp/clip (9), is fixed on the oil pipe lateral wall.
What the utility model adopted places by linear electric motors and linear axis oil pump the technical scheme that the oil well shaft bottom replaces traditional ground oil pumper, and the positive beneficial effect had is as follows:
1. straight line downhole pumping installation energy consumption is low, and energy-saving effect is obvious.The oil pumper hoisting system is energy-conservation relatively can reach more than 20%;
2. the straight line downhole pumping installation has been cancelled rod string, adopts the cable transferring power, has thoroughly solved the side-abrasion of rod string problem.
3. straight line downhole pumping installation ground adopts Based Intelligent Control, adjusts the simple aspect of ginseng, and ground does not have the big machinery lifting equipment, has significantly reduced oil well line service amount, has reduced staff labor intensity, has improved efficiency.
4, the liquid that sand control screen and sand control device suck for the protection of the straight line downhole pump does not contain the bulky grain sandstone, in order to avoid damage the pump housing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The specific embodiment
As shown in Figure 1; a kind of straight line downhole pumping installation, mainly comprise ground drives 1, driving cable 2, straight line downhole pump 3, straight line underground reciprocating group of motors 4, sand control screen 5, sand control device 6, driving cable down-hole connector 7, motor protecting cover 8, cable fixing clamp/clip 9, import fastener 10 etc.Ground drives 1 is 660V medium voltage converter control device, and ground drives 1 is connected by driving cable down-hole connector 7 with straight line underground reciprocating group of motors 4, for driving 4 work of straight line underground reciprocating group of motors.Straight line underground reciprocating group of motors 4 is connected with oil well pump 3, drives straight line downhole pump 3 after ground drives 1 work oil water mixture is lifted in oil pipe 10, and oil pipe 10 extends to ground always and finally oil water mixture is delivered in production station.
Described sand control screen 5 does not contain the bulky grain sandstone with the liquid that sand control device 6 sucks for the protection of straight line downhole pump 3, in order to avoid damage the pump housing.Described cable fixing clamp/clip 9 is for the protection driving cable designs, and prevents in driving cable and well friction and damages, and described well head fastener 11 is done wellhead sealing design for driving cable 2 from well head is drawn, and prevents the oil water mixture leakage of extracting out.
Operating principle of the present utility model: the straight line oil pumping system has been cancelled ground oil pumper and sucker rod, with linear motor, is used as power, and electromechanics is became one, and directly is placed in oil well.Straight reciprocating motion by motor, drive the reciprocating action of oil well pump inner plunger, fluid is raised to ground from shaft bottom, technique, can thoroughly overcome sucker rod partial wear, maintenance workload that conventional sucker-rod pumping system exists large, expend the problems such as the energy is many.
