Description

Technical Field

[0001] The utility model relates to the technical field of oil pumping units, in particular to a coordinate type oil pumping unit. Background Art

[0002] As most of the domestic oil wells have entered the middle and late stages, a large number of old oil fields with high water content are being developed in the late stages, and special oil fields such as heavy oil, high condensate oil, wax deposition, and sand production are being developed, which has led to an increase in the depth and displacement of the wells. The oil production process has put forward requirements for rod pumping equipment such as long stroke, low stroke, large pump, and deep pumping. At present, my country's oil fields mainly use beam pumping units and bailing pumping units.

[0003] However, practice shows that the existing oil pumping units have the following problems: the oil beam type oil pumping unit has a simple structure and is durable, but due to the limitations of its working principle and structure, it has low mechanical efficiency, unstable operation, and difficulty in adjusting the stroke and stroke frequency, which makes it difficult to meet the mining needs, especially the high energy consumption. When the stroke is large, the overall size of the walking beam type oil pumping unit increases, the torque of the reduction box increases, and the weight and cost of the whole machine increase significantly, which does not conform to the concept of energy saving and environmental protection; and although the lifting oil pumping unit can be used for long strokes, the flexible oil pumping rod it uses is a flexible material attached to the surface of the wire rope. When the curvature radius of the drum is small, the flexible oil pumping rod is subjected to greater tension and pressure, causing it to be damaged in a short time, thereby causing crude oil to leak from the damaged area. Therefore, the effect is not good during use.

[0004] Therefore be necessary to invent a kind of coordinate type oil pumping unit to solve above-mentioned problem. Utility Model Content

[0006] The utility model is realized by adopting the following technical solutions:

[0007] A coordinate type oil pumping unit comprises an oil wellhead, a wellhead foundation, a fixed support mechanism, an adjustment and movement mechanism, a driving mechanism, and a steel wire rope, at least one end of the two ends of the steel wire rope is connected to an oil pump rod, and the lower end of the oil pump rod is connected to an oil pump;

[0008] The fixed support mechanism comprises a base installed on the wellhead foundation, and a track is fixed on the upper surface of the base;

[0009] The adjustment and movement mechanism includes a fine-tuning mechanism, a support frame, and a reel. The fine-tuning mechanism is fixed to the top of the track. A pulley assembly is fixed to the bottom of the support frame. The pulley assembly is rollingly assembled on the track. The reel is rotatably mounted on the support frame. A spiral groove is provided on the outer edge of the reel. The steel wire rope is wound in the spiral groove. The top of the fine-tuning mechanism is slidably connected to the spiral groove.

[0010] The driving mechanism includes a driving motor, a reducer, a bearing seat, and a controller. The output shaft of the driving motor is connected to the input shaft of the reducer, and the output shaft of the driving motor is rotatably connected to the top of the support frame through the bearing seat. The output shaft of the reducer is fixedly connected to the reel, and the controller is electrically connected to the driving motor.

[0011] Furthermore, there are two tracks, and the two tracks are symmetrically arranged front and back about the reel, each track includes a first cross rail and a second cross rail in an I-shape, and the first cross rail is located on the side close to the reel, and the first cross rail and the second cross rail are fixed to the base.

[0012] Furthermore, the pulley assembly includes two connecting plates distributed along the front and back, the two connecting plates are respectively located on the front and back sides of the first cross rail, and the top ends of the two connecting plates are fixed to the bottom end of the support frame, and the upper pulley and the lower pulley distributed along the upper and lower sides are installed between the two connecting plates through the wheel axle, and the upper pulley and the lower pulley are respectively assembled at the upper and lower ends of the first cross rail.

[0013] Furthermore, the fine-tuning mechanism includes a vertical rod fixed to the middle of the upper end of the second horizontal rail, a wedge-shaped adjustment rod is fixed to the top of the vertical rod, the inclined width of the adjustment rod matches the groove width of the spiral groove, and the inclined surface of the adjustment rod contacts the inner surface of the spiral groove.

[0014] Furthermore, the reducer is a planetary reducer.

[0015] Furthermore, the driving motor is equipped with a brake.

[0016] Furthermore, the upper surface of the first cross rail is bolted with two limiters distributed along the left and right sides, and the pulley assembly is located between the two limiters, and each limiter is electrically connected to the controller.

[0017] Further, when only one end of the steel wire rope is connected to the oil pump rod, the other end of the steel wire rope is connected to a cement counterweight.

[0018] Furthermore, the diameter of the reel is 4m.

[0019] Compared with the existing oil pumping unit, the utility model has a reasonable and reliable design and has the following beneficial effects:

[0020] 1. The use of planetary reducers not only improves the power transmission efficiency, but also reduces energy consumption, solves the problem of high energy consumption of traditional oil pumping units, and makes the operation more stable. At the same time, with the large-diameter reel design, the reel diameter is 4 meters, which means that the single-turn stroke can reach 12 meters, and the linear speed of the reel is relatively small. Under the same wellhead load, the matching motor power is smaller, which is more energy-saving and environmentally friendly.

[0021] 2. The fixed support mechanism and the adjusting and moving mechanism together constitute a coordinate operation structure. The limiter is used in conjunction with the controller and the drive motor to control the drum to switch between clockwise rotation and counterclockwise rotation. At the same time, through the cooperation of the fine-tuning mechanism and the spiral groove, the drum makes reciprocating motion in the horizontal direction while the pump rod is always located in the center of the oil wellhead to maintain reciprocating motion in the vertical direction, which effectively increases the stroke of the pumping unit, ensures the accuracy and stability of the pumping unit operation, greatly optimizes the pumping efficiency, and also reduces the extra energy consumption and wear of the pump rod caused by deviation from the center of the oil wellhead.

[0022] 3. The support frame is fixed above the fixed support mechanism through a pulley combination, which ensures the stability and safety of the oil pump and reduces the deviation caused by vibration or wind.

[0023] 4. The cooperation between the limiter and the controller can change the reciprocating motion range of the drum driven by the support frame through the pulley combination by adjusting the installation position of the limiter, thereby realizing flexible adjustment of the stroke of the oil pumping unit and improving the adaptability of the oil pumping unit.

[0024] 5. The use of a large-diameter reel can greatly increase the effective stroke and reduce energy loss even in ultra-long-stroke oil wells. It takes a longer time to complete a stroke, which can reduce the wear of the oil pump and increase its service life without significantly increasing the size of the equipment. When the oil pump rod is bent, the compression or tension damage is small, which increases the service life of the oil pump rod and saves costs. At the same time, due to the large curvature radius of the reel, it can match various types of oil pump rods, such as flexible oil pump rods and continuous oil pump rods, which improves the versatility of this oil pumping unit.

[0025] 6. This oil pumping unit is suitable for both single-well and double-well oil production, which improves work flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] A coordinate type oil pumping unit, as shown in the attached Figure 1 ~Attached Figure 3 As shown, it includes an oil wellhead 1, a wellhead foundation 2, a fixed support mechanism, an adjustment and movement mechanism, a driving mechanism, and a wire rope 3. At least one end of the wire rope 3 is connected to a pump rod 4, and the lower end of the pump rod 4 is connected to a pump.

[0031] The fixed support mechanism comprises a base 5 mounted on the wellhead foundation 2, and a track is fixed on the upper surface of the base 5;

[0032] The adjustment and movement mechanism includes a fine-tuning mechanism, a support frame 6, and a reel 7. The fine-tuning mechanism is fixed to the top of the track. A pulley assembly is fixed to the bottom of the support frame 6. The pulley assembly is rollingly assembled on the track. The reel 7 is rotatably mounted on the support frame 6. A spiral groove 8 is opened on the outer edge of the reel 7. The wire rope 3 is wound in the spiral groove 8. The top of the fine-tuning mechanism is slidably connected to the spiral groove 8.

[0033] The driving mechanism includes a driving motor 9, a reducer 10, a bearing seat 11, and a controller. The output shaft of the driving motor 9 is connected to the input shaft of the reducer 10, and the output shaft of the driving motor 9 is rotatably connected to the top of the support frame 6 through the bearing seat 11. The output shaft of the reducer 10 is fixedly connected to the reel 7, and the controller is electrically connected to the driving motor 9.

[0034] The fixed support mechanism composed of the base 5 and the track in the utility model provides the basic support for the entire oil pumping unit, ensuring that the oil pumping unit is firmly installed on the wellhead foundation. At the same time, the track guides the support frame 6 to drive the drum 7 to move along a predetermined path through the pulley combination, ensuring the stability and safety of the oil pumping unit and reducing the deviation caused by vibration or wind. The fixed support mechanism and the adjustment and movement mechanism together form a coordinate operation structure. The structural design of the drum 7 in the adjustment and movement mechanism can carry the wire rope 3 and provide power transmission. The spiral groove 8 can limit the wire rope 3 on the one hand, and on the other hand, cooperate with the fine adjustment mechanism to enable the drum 7 to move horizontally on the track through the support frame 6 and the pulley combination while rotating, so that the pump rod 4 can always be located at the center of the oil well wellhead 1 to maintain vertical movement, thereby effectively increasing the stroke of the oil pumping unit, greatly optimizing the pumping efficiency, and also reducing the extra energy consumption and wear of the pump rod 4 due to deviation from the center of the oil well wellhead 1. The driving mechanism provides power for the oil pumping unit, wherein the reducer 10 converts high-speed rotation into low-speed high torque, effectively improving the power transmission efficiency.

[0035] As attached Figure 1 ~Attached Figure 3 As shown, there are two tracks, and the two tracks are symmetrically arranged front and back about the reel 7, each track includes a first cross rail 12 and a second cross rail 13 in an I-shape, and the first cross rail 12 is located on the side close to the reel 7, and the first cross rail 12 and the second cross rail 13 are fixed to the base 5.

[0036] The structural design of the first transverse rail 12 and the second transverse rail 13 plays a role in supporting and adjusting the moving mechanism.

[0037] As attached Figure 1 ~Attached Figure 2 As shown, the pulley assembly includes two connecting plates 14 distributed along the front and rear, the two connecting plates 14 are respectively located on the front and rear sides of the first cross rail 12, and the top ends of the two connecting plates 14 are fixed to the bottom end of the support frame 6, and an upper pulley 15 and a lower pulley 16 distributed along the upper and lower directions are installed between the two connecting plates 14 through a wheel axle, and the upper pulley 15 and the lower pulley 16 are respectively assembled at the upper and lower ends of the first cross rail 12.

[0038] The structural design of the pulley assembly consisting of the connecting plate 14 , the axle, the upper pulley 15 , and the lower pulley 16 enables the support frame 6 to be stably connected and moved on the first cross rail 12 through the pulley assembly.

[0039] As attached Figure 1 ~Attached Figure 3As shown, the fine-tuning mechanism includes a vertical rod 17 fixed to the middle part of the upper end of the second cross rail 13, and a wedge-shaped adjusting rod 18 is fixed to the top of the vertical rod 17. The inclined width of the adjusting rod 18 matches the groove width of the spiral groove 8, and the inclined surface of the adjusting rod 18 contacts the inner surface of the spiral groove 8.

[0040] The structural design of the fine-tuning mechanism can adjust the position of the oil pump rod 4 so that the oil pump rod 4 is always located at the center of the oil wellhead 1 and maintains reciprocating motion in the vertical direction. Among them, the vertical rod 17 plays the role of supporting and fixing the adjusting rod 18. The wedge-shaped adjusting rod 18 is slidably connected to the drum 7 through the spiral groove 8, which guides the drum 7 to make left and right reciprocating motion along the first cross rail 12 while rotating.

[0041] As attached Figure 2 As shown, the reducer 10 is a planetary reducer.

[0042] The planetary reducer further improves the power transmission efficiency, reduces energy consumption, solves the problem of high energy consumption of traditional oil pumps, and operates stably.

[0043] As attached Figure 2 As shown, the driving motor 9 is equipped with a brake 19 .

[0044] The brake 19 can control the start and stop of the drive motor 9 to ensure safe operation.

[0045] As attached Figure 1 ~Attached Figure 3 As shown, the upper surface of the first cross rail 12 is bolted with two limiters 20 distributed along the left and right sides, and the pulley assembly is located between the two limiters 20, and each limiter 20 is electrically connected to the controller.

[0046] The limiter 20, by cooperating with the controller and the drive motor 9, can not only control the switching between the clockwise rotation and the counterclockwise rotation of the drum 7, but also control the movement range of the pulley combination. By adjusting the installation position of the limiter 20, the reciprocating motion range of the drum 7 driven by the support frame 6 through the pulley combination can be changed, thereby realizing flexible adjustment of the stroke of the oil pumping unit and improving its adaptability.

[0047] As attached Figure 1 ~Attached Figure 2 As shown, when only one end of the steel wire rope 3 is connected to the oil pump rod 4, the other end of the steel wire rope 3 is connected to the cement balance weight 21.

[0048] When the two ends of the wire rope 3 are respectively connected to the oil pump rod 4 and the cement balance weight 21, the cement balance weight 21 can balance the load during the oil pumping process of single well oil production, reduce the power demand of the drive motor 9, reduce energy consumption, and thus improve economic benefits.

[0049] As attached Figure 1 ~Attached Figure 2 As shown, the diameter of the reel 7 is 4 m.

[0050] The large diameter design of the drum 7 can match various types of oil pump rods 4, such as flexible oil pump rods and continuous oil pump rods, which improves the versatility of the present oil pumping unit. Moreover, due to the large curvature radius of the drum 7, the oil pump rod 4 is less damaged by compression or tension when it is bent, thereby increasing the service life of the oil pump rod 4 and saving costs. Moreover, the single-turn stroke of the drum 7 with a diameter of 4m can reach 12 meters. For ultra-long stroke oil wells, a 50m ultra-long oil pump can be matched, which can greatly increase the effective stroke and reduce energy loss. The time to complete a stroke is longer, which can reduce the wear of the oil pump and increase its service life. Furthermore, the linear speed of the large-diameter drum 7 is smaller. Under the same wellhead load, the power of the matching drive motor 9 is smaller, which is more energy-saving and environmentally friendly.

[0051] The present invention is further described in detail below through specific embodiments. It should be noted that the present invention is not limited to the following embodiments. Example 1

[0052] In this embodiment, the two ends of the steel wire rope 3 are respectively connected to the oil pump rod 4 and the cement balance weight 21, that is, single well oil production is carried out.

[0053] During installation, first fix the base 5 of the oil pumping unit on the wellhead foundation 2 of the oil production plant, and weld the first cross rail 12 and the second cross rail 13 to the base 5 to ensure stability. After ensuring stability, adjust the position of the limiter 20 on the first cross rail 12 according to the specific conditions of the oil well and fix it with bolts. The required stroke length is set by the distance between the two limiters 20 on the same first cross rail 12. Then, the adjusting and moving mechanism is installed on the track to ensure that the pulley combination on each first cross rail 12 is located between the two limiters 20 corresponding to the first cross rail 12, and the inclined surface of the adjusting rod 18 is in contact with the inner surface of the spiral groove 8. Then, the driving mechanism is installed on the adjusting and moving mechanism, and the wire rope 3 is wound in the spiral groove 8 of the drum 7, and the two ends are respectively connected to the oil pump rod 4 and the cement balance weight 21 to ensure that the oil pump rod 4 is vertically inserted in the center of the wellhead 1 of the oil well, and the lower end of the oil pump rod 4 is connected to the oil pump.

[0054] When working, the drive motor 9 is started, the brake 19 is released, and the drive motor 9 transmits power to the drum 7 through the reducer 10. When the drum 7 rotates counterclockwise, it drives one end of the wire rope 3 connected to the oil pump rod 4 to move vertically downward, and drives the other end of the wire rope 3 and the cement balance weight 21 connected to it to move vertically upward. At the same time, due to the cooperation of the fine-tuning mechanism through the adjusting rod 18 and the spiral groove 8, the support frame 6 drives the drum 7 to move along the first cross rail 12 through the pulley combination toward the limiter 20 located on the left side of the first cross rail 12. In this process Ensure that the pump rod 4 is always located at the center of the wellhead 1 of the oil well and keeps moving in the vertical direction. When the pulley assembly moves and contacts the sensing element on the inner side of the limiter 20 on the left side of the first cross rail 12, the sensing element is triggered and sends a signal to the controller. After receiving the signal, the controller controls the drive motor 9 to change the rotation direction in real time. At this time, the drum 7 rotates clockwise, driving the pump rod 4 connected to one end of the wire rope 3 to move vertically upward, and driving the other end of the wire rope 3 and the cement balance weight 21 connected to it to move vertically downward. At the same time, due to the fine-tuning mechanism through The adjustment rod 18 cooperates with the spiral groove 8, so that the support frame 6 drives the reel 7 to move along the first transverse rail 12 toward the limiter 20 located on the right side of the first transverse rail 12 through the pulley combination. In this process, it is ensured that the oil pump rod 4 is always located at the center of the wellhead 1 of the oil well and maintains vertical movement. When the pulley combination moves and contacts the sensing element on the inner side of the limiter 20 located on the right side of the first transverse rail 12, the sensing element is triggered and sends a signal to the controller. After receiving the signal, the controller controls the drive motor 9 to change the rotation direction in real time, thereby the vertical up and down movement of the oil pump rod 4 is controlled. Within the preset range, a complete stroke cycle is completed, and then the stroke cycle can be continuously repeated to carry out subsequent oil production work. When the pumping unit needs to be stopped, it is only necessary to engage the brake 19 to stop it, and then turn off the drive motor 9 to ensure safe operation, thereby completing the use of the pumping unit; it overcomes the problems of low mechanical efficiency, poor working stability, inconvenient adjustment of stroke and stroke frequency, excessive energy consumption, sharp increase in equipment size and cost with increase in stroke, and easy damage of flexible sucker rods in lifting pumping units, resulting in crude oil leakage. Example 2

[0055] In this embodiment, the two ends of the steel wire rope 3 are respectively connected to a pump rod 4, that is, double-well oil production is carried out.

[0056] During installation, first fix the base 5 of the oil pumping unit on the wellhead foundation 2 of the oil production plant, and weld the first cross rail 12 and the second cross rail 13 to the base 5 to ensure stability. After ensuring stability, adjust the position of the limiter 20 on the first cross rail 12 according to the specific conditions of the oil well and fix it with bolts. The required stroke length is set by the distance between the two limiters 20 on the same first cross rail 12. Then, the adjusting and moving mechanism is installed on the track to ensure that the pulley assembly on each first cross rail 12 is located between the two limiters 20 of the corresponding first cross rail 12, and the inclined surface of the adjusting rod 18 is in contact with the inner surface of the spiral groove 8. Then, the driving mechanism is installed on the adjusting and moving mechanism, and the wire rope 3 is wound in the spiral groove 8 of the drum 7, and an oil pump rod 4 is connected to each of the two ends to ensure that each oil pump rod 4 is vertically inserted in the center of the corresponding oil wellhead 1, and the lower end of each oil pump rod 4 is connected to an oil pump.

[0057] When working, the drive motor 9 is started, the brake 19 is released, and the drive motor 9 transmits power to the drum 7 through the reducer 10. When the drum 7 rotates counterclockwise, the front end of the wire rope 3 and the oil pump rod 4 connected thereto are driven to move vertically downward, and the rear end of the wire rope 3 and the oil pump rod 4 connected thereto are driven to move vertically upward. At the same time, due to the cooperation between the fine-tuning mechanism through the adjusting rod 18 and the spiral groove 8, the support frame 6 drives the drum 7 to move along the first transverse rail 12 through the pulley combination toward the limiter 20 located on the left side of the first transverse rail 12, and in this process, each oil pump is ensured to move vertically upward. The pump rod 4 is always located at the center of the corresponding oil well head 1 and keeps moving in the vertical direction. When the pulley assembly moves and contacts the sensing element on the inner side of the limiter 20 on the left side of the first horizontal rail 12, the sensing element is triggered and sends a signal to the controller. After receiving the signal, the controller controls the drive motor 9 to change the rotation direction in real time. At this time, the drum 7 rotates clockwise, driving the front end of the wire rope 3 connected to the oil pump rod 4 to move vertically upward, and driving the rear end of the wire rope 3 connected to the oil pump rod 4 to move vertically downward. At the same time, the fine adjustment mechanism adjusts the adjustment rod 18 The support frame 6 cooperates with the spiral groove 8, so that the support frame 6 drives the reel 7 to move along the first transverse rail 12 toward the limiter 20 located on the right side of the first transverse rail 12 through the pulley combination. In this process, it is ensured that each oil pump rod 4 is always located at the center of the corresponding oil wellhead 1 to maintain vertical movement. When the pulley combination moves and contacts the sensing element on the inner side of the limiter 20 located on the right side of the first transverse rail 12, the sensing element is triggered and sends a signal to the controller. After receiving the signal, the controller controls the drive motor 9 to change the rotation direction in real time, thereby the vertical up and down movement of each oil pump rod 4 is All are limited within a preset range, completing a complete stroke cycle, and then the stroke cycle can be continuously repeated to carry out subsequent oil production work. When the pumping unit needs to be stopped, it is only necessary to engage the brake 19 to stop it, and then turn off the drive motor 9 to ensure safe operation, thereby completing the use of the pumping unit; it overcomes the problems of low mechanical efficiency, poor working stability, inconvenient adjustment of stroke and stroke frequency, excessive energy consumption, sharp increase in equipment size and cost as the stroke increases, and the problem of flexible sucker rod in the lifting pumping unit being easy to damage and causing crude oil leakage.
