Description

Technical Field

[0001] The utility model relates to the technical field of oil exploitation, in particular to a wax deposition monitoring and early warning device for a wellbore of an oil pumping well. Background Art

[0002] The formation of wax deposition is a complex process, which mainly occurs in various links of crude oil extraction, transportation and processing. With the deepening of crude oil extraction, waxy substances in crude oil will precipitate in the form of crystals under certain conditions and deposit on the walls of oil casing, sucker rods, pumps and other equipment. This phenomenon poses a great threat to the production efficiency of oil wells and the safe operation of equipment.

[0003] The main causes of wax deposition in oil wells are as follows: 1. When the wax content in crude oil is higher, wax deposition is more likely to occur on the inner wall of the oil well.

[0004] 2. If the pressure in the oil well is greater than the saturation pressure in the environment, the temperature at which paraffin crystallizes will be greatly reduced. At the same time, when the gas in the crude oil continues to overflow, the temperature at which paraffin crystallizes will increase.

[0005] 3. The presence of a large amount of impurities in the oil is also the main cause of wax deposition. First, when there are a large number of impurities in the crude oil, the specific heat capacity of the water component in the crude oil will increase, so that the heat of the crude oil will flow into the water component, causing the temperature of the crude oil to drop significantly. Secondly, the presence of impurities will cause the water component to form a thin film on the inner wall of the oil well, and the presence of this film provides the prerequisite for paraffin deposition.

[0006] 4. The flow rate of the liquid phase in crude oil may promote or slow down the deposition of paraffin. When the liquid phase flows faster, the heat loss of oil will be reduced. At the same time, the high-speed flowing liquid phase will have a certain scouring effect on the pipe wall, making it difficult for paraffin to deposit on the pipe wall. Even if a small amount of paraffin gets a chance to deposit, it will be carried away by the fast-flowing liquid phase.

[0007] The harm of wax deposition in oil wells is mainly reflected in the following aspects: 1. Reduced oil well production: wax deposition will reduce the diameter of the oil pipe, increase the outer diameter of the pumping rod, increase the oil flow resistance, and reduce the oil well production. In severe cases, it may even block the oil well and make it unable to produce.

[0008] 2. Increase production input costs: Waxing will increase the power loss required by the oil pumping equipment, increase the production input costs of oilfield enterprises, and is not conducive to improving the economic benefits of the enterprise.

[0009] 3. Impact on the operation of oil pumping equipment: Wax deposition in oil wells will occupy part of the underground space, reduce the space occupied by the mechanical equipment for oil pumping, and increase the pressure and resistance of crude oil circulation. At the same time, it will cause the valve ball and valve seat to fail, causing the oil pump to move out of the fixed position, and even cause the oil pump to be stuck, shortening the service life and inspection cycle of the oil pump.

[0010] 4. Increased workload: Wax deposition will increase the workload downhole. If the wax deposition problem occurs at the wellhead of the oil well, the back pressure at the wellhead will increase significantly. At the same time, wax deposition can easily cause eccentric wear on the rod and pipe, further increasing the workload.

[0011] 5. Affect the service life of the sucker rod: wax deposition causes an increase in alternating loads, affecting the service life of the sucker rod.

[0012] Therefore, effective wax removal and prevention measures must be taken, such as adding chemical wax inhibitors or using wax removal equipment, to reduce the hazards of wax deposition in oil wells and ensure the normal, safe and orderly production of oil wells.

[0013] The wax deposition phenomenon is not discovered until the oil output of the oil well is significantly affected. However, at this time, the wax deposition on the pipe wall is already thick, making it more difficult to clean, and the best time to clean the inner wall of the wellbore is missed.

[0014] At the same time, we must strengthen the improvement of pumping equipment and processes to reduce the impact of wax deposition on oil well production. Through these measures, it is expected that the adverse effects of wax deposition on crude oil production will be reduced, and the production efficiency of oil wells and the safe operation level of equipment will be improved. In addition, increasing the research and development of oil extraction technology, optimizing the production process, and reducing the generation of wax deposition from the source are also important ways to improve the efficiency of crude oil production.

[0015] CN201810067582.3 discloses a device and method for monitoring, warning and disposing of solids in a wellbore during mining, which is applicable to wellbores containing solids or generating solids, such as oil wells, gas wells, hydrate wells and fluidized mines, for monitoring, warning and disposing of solids. The device includes: a gas-liquid-solid multiphase flow conveying system, a solids monitoring system, an underground data acquisition and transmission system, a solids situation assessment system, a solids warning device and its auxiliary system and a solids blockage disposal system, that is, using acoustic wave measurement, resistance measurement, dielectric constant measurement, nuclear magnetic resonance imaging, optical transmission imaging, ultrasonic imaging, temperature and pressure and other testing methods to comprehensively monitor the solids in the wellbore, and using the characteristic that the speed of the electrical signal is faster than the speed of the fluid for early warning, and early judgment, warning, intelligent disposal or manual disposal of possible blockages.

[0016] The above patent still has many shortcomings. First of all, the core of the above patent is to combine the gas-liquid-solid multiphase flow conveying system, the solid monitoring system, the downhole data acquisition and transmission system, the solid situation assessment system, the solid early warning equipment and its auxiliary system and the solid blockage disposal system to monitor, warn and dispose of the solids in the wellbore. However, the shortcoming of this patent is that although it has a comprehensive design of the monitoring and early warning equipment for wellbore solids, in actual operation, the stability and reliability of these devices still need to be further verified.

[0017] Secondly, although the above patents mention the use of a variety of monitoring methods, such as acoustic wave measurement, resistance measurement, dielectric constant measurement, nuclear magnetic resonance imaging, optical imaging, ultrasonic imaging, temperature and pressure, etc., the accuracy, precision and stability of these monitoring methods in practical applications also need further research and optimization. Especially in complex wellbore environments, how to ensure the accuracy of these monitoring methods and how to effectively convert these monitoring data into an assessment of the solid situation are problems that the present invention needs to solve.

[0018] Again, although the early warning equipment and its auxiliary system mentioned in the above patent use the characteristic that the speed of electrical signals is faster than the speed of fluids for early warning, in actual operation, how to accurately judge and predict the blockage of solid matter, and how to effectively conduct early judgment, early warning, intelligent disposal or manual disposal, is still a challenge.

[0019] In addition, although the solid blockage disposal system mentioned in the above patent is feasible in theory, in actual application, how to ensure the efficiency and safety of the disposal system and how to avoid damage to the wellbore environment and equipment during the disposal process are also issues that need further consideration.

[0020] Finally, the above patent does not involve real-time adjustment and optimization in the process of wellbore solids monitoring, early warning and disposal, which may affect the effect of solids monitoring, early warning and disposal. How to make dynamic adjustments based on real-time monitoring data to improve the efficiency and accuracy of solids monitoring, early warning and disposal is an area that needs to be further improved in the present invention.

[0021] In summary, although the above patent provides a new solution for the monitoring, early warning and disposal of wellbore solids, in actual application, in-depth research and optimization are still needed on the stability of the equipment, the accuracy of the monitoring means, the efficiency of early warning and disposal, etc.

[0022] Only by deeply understanding the causes, hazards and prevention measures of wax deposition can we effectively solve this problem, improve crude oil production efficiency, ensure the safe operation of oil well equipment, and lay the foundation for the sustainable development of the crude oil industry. On this basis, strengthening scientific and technological innovation, continuously developing and applying new wax removal and prevention technologies will help reduce the impact of oil well wax deposition on crude oil production and further enhance the competitiveness of the crude oil industry. Summary of the invention

[0023] The utility model aims to solve the problems existing in the background technology and proposes a wax deposition monitoring and early warning device for a wellbore of a pumping unit, so as to solve the problem that there is no mechanism for real-time monitoring of wax deposition in the existing wellbore of the pumping unit, whether the inner wall of the wellbore is waxed and the degree of wax deposition cannot be obtained in real time, and the staff can only know it when the oil output is obviously affected in the later stage, and the wax deposition thickness of the pipe wall is large in the later stage, and the cleaning difficulty coefficient is large, which easily makes the staff miss the best time to clean the inner wall of the wellbore. The technical solution is as follows:

[0024] A wax deposition monitoring and early warning device for a wellbore of an oil pumping unit comprises a connecting pipe, a monitoring ring, a movable pipe, a pressure sensor and a control box. The two ends of the connecting pipe are respectively detachably provided with oil pipes, and the inner diameter of the connecting pipe is the same as the inner diameter of the oil pipe. The monitoring ring is arranged in the connecting pipe, and the outer wall of the monitoring ring is sealed with the inner wall of the connecting pipe. A mounting piece for limiting the sliding of the monitoring ring is arranged on the connecting pipe. The movable pipe is arranged in the connecting pipe and is slidably connected thereto, and the outer wall of the movable pipe is sealed with the inner wall of the connecting pipe. An annular groove B is arranged on the movable pipe, and the monitoring ring is located in the annular groove B and is slidably connected thereto, and the inner wall of the monitoring ring is sealed with the outer wall of the annular groove B. The pressure sensor is arranged on the lower surface of the monitoring ring, and the detection end of the pressure sensor abuts against the bottom surface of the annular groove B. The control box is detachably arranged on the outer wall of the connecting pipe, and a signal transceiver module and a controller are arranged in the control box, the controller is communicatively connected to the pressure sensor, and the controller is electrically connected to the signal transceiver module.

[0025] Preferably, bolts are also included. Flanges A are symmetrically arranged on the connecting pipe, flanges B are arranged on the oil pipes on both sides, and the flanges B on both sides are respectively connected to the corresponding side flanges A through a plurality of bolts.

[0026] Preferably, two short grooves are symmetrically arranged in the connecting pipe, and a boss is arranged on the oil pipe, and the boss is inserted into the short groove and sealed therewith.

[0027] Preferably, two annular grooves A are symmetrically arranged in the connecting pipe, and the annular grooves A on both sides correspond to the corresponding side short grooves respectively. A sealing ring is arranged in the annular groove A, and the inner wall of the sealing ring through hole abuts against the outer wall of the boss.

[0028] Preferably, the mounting member includes a screw. The connecting tube is provided with a plurality of through holes connected to the interior thereof around its axis, and the connecting tube is provided with a plurality of circular grooves connected to the through holes, each circular groove is coaxial with the corresponding through hole, and a sealing gasket is provided in the circular groove. The monitoring ring is provided with a plurality of threaded holes corresponding to the through holes, each screw passes through the corresponding side through hole and is spirally inserted into the threaded hole, and the screw passes through the sealing gasket and is slidably connected thereto, and the end cap of the screw abuts against the outer surface of the sealing gasket.

[0029] Preferably, a plurality of support rods slidably connected to the monitoring ring are provided on the monitoring ring, and two ends of the support rods are connected to the upper wall and the lower wall of the annular groove B respectively.

[0030] Preferably, a battery pack is also included. A bracket is arranged on the control box, a photovoltaic panel is arranged on the bracket, the photovoltaic panel is electrically connected to the battery pack, and the battery pack is electrically connected to each electrical device.

[0034] The utility model provides a monitoring ring and a sliding matching structure of the movable tube in the connecting tube, which has the following significant technical advantages compared with the prior art.

[0035] During the oil production process, oil flows upward from the lower oil pipe into the connecting pipe, and then is discharged along the upper oil pipe. Since the output power of the oil production pump remains constant, when there is no wax deposition in the oil pipe, the oil pressure inside the oil pipe remains unchanged. In this case, when the flowing oil passes through the movable pipe with a smaller inner diameter, it pushes the movable pipe upward, causing it to move upward and contact the pressure sensor.

[0036] The pressure sensor is responsible for detecting the pressure data and comparing it with the initial oil production pressure value. If the pressure data is consistent with the initial oil production pressure value, it means that there is no wax inside the oil pipe, or the degree of wax deposition has no effect on the oil production process. However, if the pressure data increases, it means that the pressure inside the oil pipe has increased, and it can be judged that wax deposition on the inner wall of the oil pipe has begun to affect the oil production efficiency.

[0037] Once the pressure data is detected to be abnormal, the pressure value will be sent to the monitoring station through the signal transceiver module, so that the staff can understand the situation in time and take corresponding wax removal measures. This equipment has the advantages of simple structure, convenient operation and low cost, which helps to improve oil recovery efficiency and reduce maintenance costs, and has high practical value.

[0038] In summary, the utility model realizes real-time monitoring of wax deposition inside the oil pipe by setting a monitoring ring in the connecting pipe and a sliding matching structure of the movable pipe, effectively improving oil recovery efficiency and providing strong support for oil field development. In oil field production, it is very important to timely discover and solve the wax deposition problem. The utility model just provides an efficient and convenient solution to this problem.

DETAILED DESCRIPTION

[0044] Example 1

[0045] like Figure 1-4 As shown, the utility model proposes a wax deposition monitoring and early warning device for a wellbore of a pumping unit, comprising a connecting pipe 1, a monitoring ring 6, a movable pipe 8, a pressure sensor 9 and a control box 10. The two ends of the connecting pipe 1 are respectively detachably provided with an oil pipe 3, and the inner diameter of the connecting pipe 1 is the same as the inner diameter of the oil pipe 3. The monitoring ring 6 is arranged in the connecting pipe 1, and the outer wall of the monitoring ring 6 is sealed with the inner wall of the connecting pipe 1, and a mounting part for limiting the sliding of the monitoring ring 6 is arranged on the connecting pipe 1. The movable pipe 8 is arranged in the connecting pipe 1 and is slidably connected thereto, and the outer wall of the movable pipe 8 is sealed with the inner wall of the connecting pipe 1, and an annular groove B801 is arranged on the movable pipe 8, and the monitoring ring 6 is located in the annular groove B801 and is slidably connected thereto, and the inner wall of the monitoring ring 6 is sealed with the outer wall of the annular groove B801. The pressure sensor 9 is arranged on the lower surface of the monitoring ring 6, and the detection end of the pressure sensor 9 abuts against the bottom surface of the annular groove B801.

[0046] The control box 10 is detachably arranged on the outer wall of the connecting pipe 1 , and a signal transceiver module and a controller are arranged in the control box 10 . The controller is communicatively connected with the pressure sensor 9 , and the controller is electrically connected with the signal transceiver module.

[0047] In this embodiment, the connecting pipe 1 is connected between the two sections of the oil pipe 3 and then locked to form a sealed connection. At this time, the connecting pipe 1 and the internal passage of the oil pipe 3 are of the same size. When producing oil, the oil goes up along the lower oil pipe 3 into the connecting pipe 1 and is discharged along the upper oil pipe 3. Since the output power of the oil production pump remains unchanged, if there is no wax deposition in the oil pipe 3, the internal oil pressure remains unchanged. When the flowing oil passes through the movable pipe 8 with a smaller inner diameter, it will push up the movable pipe 8. The movable pipe 8 goes up and hits the pressure sensor 9. The pressure sensor 9 detects the pressure data. If the pressure data is consistent with the initial oil production pressure value, it means that there is no wax deposition inside the oil pipe 3, or the degree of wax deposition has no effect on oil production. If the pressure data becomes larger, it means that the internal pressure of the oil pipe 3 increases, and it can be judged that the wax deposition on the inner wall of the oil pipe 3 has begun to affect the oil production efficiency (in the process of oil production, the speed remains constant when the oil outflow from the oil pipe is not blocked. If the wax deposition on the inner wall of the oil pipe is serious, the cross-sectional area of ​​the internal passage of the oil pipe will be reduced, thereby causing the oil pressure to increase). At this time, the pressure value is sent to the monitoring station through the signal transceiver module.

[0048] Example 2

[0049] like Figure 3 As shown, the utility model proposes a wax deposition monitoring and early warning device for a wellbore of an oil pumping unit. Compared with the first embodiment, two short grooves 101 are symmetrically arranged in the connecting pipe 1, a boss 301 is arranged on the oil pipe 3, and the boss 301 is inserted into the short groove 101 and sealed therewith; two annular grooves A102 are symmetrically arranged in the connecting pipe 1, and the annular grooves A102 on both sides correspond to the corresponding side short grooves 101 respectively, and a sealing ring 5 is arranged in the annular groove A102, and the inner wall of the through hole of the sealing ring 5 abuts against the outer wall of the boss 301.

[0050] In this embodiment, the boss 301 is inserted into the short groove 101 and sealed therewith. As the depth of the entire oil pipe 3 inserted into the connecting pipe 1 increases, the oil pipe 3 squeezes the sealing ring 5 to cause it to deform. The deformed sealing ring 5 is used to improve the sealing performance between the oil pipe 3 and the connecting pipe 1. At the same time, the boss 301 is used to protect the sealing ring 5 to prevent the sealing ring 5 from penetrating into the inner side of the connecting pipe 1 and contacting the oil after deformation, and to prevent the high-temperature oil from accelerating the aging of the sealing ring 5.

[0051] Example 3

[0052] like Figure 1As shown, the wax deposition monitoring and early warning device for a wellbore of an oil pumping unit proposed by the utility model further includes a battery pack compared to the first embodiment. A bracket 12 is provided on the control box 10, a photovoltaic panel 13 is provided on the bracket 12, the photovoltaic panel 13 is electrically connected to the battery pack, the battery pack is electrically connected to various electrical components, a turntable 11 rotatably connected to the control box 10 is provided inside the control box 10, the bracket 12 is connected to the turntable 11, and a locking member 14 threadedly connected to the control box 10 is provided on the control box 10, and one end of the locking member 14 is inserted into the control box 10 and abuts against the outer wall of the turntable 11.

[0053] In this embodiment, the bracket 12 is configured as a rotatable and adjustable structure, and the rotation restriction of the turntable 11 is released by rotating the locking piece 14, so that the bracket 12 can be rotated to an appropriate angle to make the photovoltaic panel 13 reach the best angle for receiving sunlight, and then the locking piece 14 can be reversed to restrict the rotation of the turntable 11.

[0054] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
