Description

Technical Field

[0001] This invention relates to the field of oil drilling and production equipment technology. More specifically, this invention relates to a drilling and well workover wire rope tension testing device and its application method. Background Technology

[0002] The tensioning rope of the vehicle-mounted workover rig is a key component for ensuring the stability of the derrick and traveling system. It is tensioned to resist lateral loads, impact vibrations and wind loads generated during operation, ensuring the safety of operations such as tripping up and running down the drill string.

[0003] Under long-term alternating loads, corrosion, and wear, the tension ropes are at risk of instability or breakage. Insufficient tension may cause the derrick to tilt or even collapse, while overload can easily lead to sudden rope breakage, both of which can cause serious accidents. At the same time, uneven tension among multiple tension ropes can cause derrick misalignment, affecting the concentricity of the tubing string during tripping and exacerbating downhole risks such as stuck pipe and wellbore collapse.

[0004] Furthermore, derricks typically have an inclination angle of 3–5°, requiring at least six traction ropes to work together for support. In situations involving soft ground, sudden unblocking, or strong winds, the system must possess dynamic adjustment capabilities. Therefore, the preload of the wire ropes is particularly important, playing a crucial role in preventing structural failure, ensuring operational safety, extending equipment lifespan, and controlling maintenance costs, thereby improving the safety and efficiency of well workover operations.

[0005] Currently, the following application methods are mainly used in oilfields: Commonly used tension sensors need to be connected to both ends of a wire rope, and all are in fixed positions. Drilling rigs have many wire ropes, especially those with rope-operated workover rigs exceeding 25 meters in length, such as those with wind-loaded ropes, ropes from the second-level platform to the ground, internal load ropes, gantry-to-frame ropes, and gantry-to-drill-platform ropes, requiring a total of twelve ropes. This necessitates twelve tension sensors, resulting in extremely high costs. Furthermore, tension sensors are susceptible to many external influencing factors and the inherent characteristics of electronic sensors, leading to issues such as zero-point drift and temperature drift, requiring regular calibration. The harsh environment in the field (vibration, temperature differences, dust) accelerates performance degradation, posing a significant risk of failure and inaccurate measurements. Summary of the Invention

[0006] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0007] Another objective of this invention is to provide a drilling and workover wire rope tension testing device and its application method, in order to solve the technical problem that the existing technology for detecting drilling and workover machine wire ropes relies on tension electronic sensors, which are easily affected by the environment, resulting in inaccurate tension measurement and difficulty in rapid and effective control.

[0008] To achieve these objectives and other advantages according to the present invention, in one aspect, the present invention provides a drilling and workover wire rope tension testing device, comprising: A mechanical transmission assembly includes a positioning component, a sleeve, a handle, a transmission rod, and a spring assembly. The lower end of the positioning component is provided with an installation space for testing the tension of a wire rope. The sleeve is vertically connected to the upper middle part of the positioning component. The transmission rod is coaxially inserted into the sleeve and its upper end is limited by the sleeve. The lower end of the transmission rod freely passes through the positioning component and extends into the installation space. A spring assembly is vertically sleeved on the outside of the transmission rod. The spring assembly is set inside the sleeve and coaxially sleeved on the outside of the transmission rod. One end of the spring assembly is connected to the transmission rod. The handle is used to adjust the height space inside the sleeve along the axial direction and to compress the spring assembly for pre-tightening. The wire rope adapter mechanism includes a double pulley set and an arc-shaped slot set in the installation space. The slot is connected to the bottom of the transmission rod. The double pulley sets are symmetrically arranged on both sides of the slot. The wire rope to be tested passes through the upper end of one pulley set, the lower end of the slot, and the upper end of the other pulley set in the same vertical direction to achieve alignment and fixation. A plane line is set on the upper end of the slot in the horizontal direction. The tension data panel is connected to the positioning component. The surface is preset with tension scales for the type of steel wire rope to be tested under different tensions. The direction of change of the tension scale is the same as the direction of movement of the plane line. The displacement of the plane line corresponds to the tension scale and displays the tension value. When the tension scale is 0, the spring assembly is in a free state.

[0009] Preferably, the spring assembly is a multi-stiffness spring parallel combination, including at least two sets of springs with different elastic coefficients.

[0010] Preferably, the positioning component includes: The top support plate is a flat plate with a through hole in the middle. The transmission rod is freely slidably connected to the through hole, and the sleeve is coaxially connected to the upper side of the top support plate. The corner brace is a right-angled plate structure. One side is fixedly connected to the bottom of the top support plate, and the other side is used to connect and install the pulley assembly. The tension data panel is connected to the other side of the corner brace facing the slot.

[0011] Preferably, the sleeve comprises: The lower cylinder has a connecting ring fixedly connected to its outer bottom, which is fixedly connected to the top support plate. The upper outer part of the lower cylinder is covered with external threads along the axial direction. The upper cylinder has a top cover that extends radially inward at its top. A through hole is provided in the middle of the top cover. The upper end of the transmission rod passes through the through hole. A limiting groove is provided at the bottom of the top cover outside the through hole. The lower end of the upper cylinder has an internal thread. The upper cylinder and the lower cylinder are connected by the mating internal and external threads. The handle is connected to the upper outer side of the upper cylinder. The outer wall of the transmission rod is connected to a limiting ring along the radial direction at the lower end of the inner side of the lower cylinder, and the spring assembly abuts between the limiting ring and the limiting groove.

[0012] Preferably, it also includes a camera module, a power module, a central controller, and a support frame. The support frame is fixed to the drilling equipment or connected to the positioning component. The camera module is electrically connected to the power module and fixed to the support frame. The camera module is positioned facing the tensile data panel and the slot. The camera module is communicatively connected to the central controller to send the captured images to the central controller for analysis and display.

[0013] On the other hand, the present invention also provides an application method for a drilling and well workover wire rope tension testing device, comprising the following steps: S1. Establish a wire rope testing and control system. For each wire rope, calibrate the linear correspondence between the wire rope tension and the spring compression of the wire rope tension testing device under the corresponding specifications. Set the tension data panel and set the tension value control range for each wire rope. S2. After adjusting the preload, set up the wire rope tension testing device of the corresponding specification and align it with the zero mark on the tension data panel. S3. Real-time acquisition of tension data and tilt angle relative to the horizontal ground of all wire ropes under tension during operation, data analysis, comparison with the set tension value control range, setting adjustment strategies, and setting weights according to the tilt angle of the wire rope to form adjustment priorities; S4. For the wire rope whose tension value exceeds the control range in step S3, the adjustment mechanism is controlled to execute the adjustment strategy according to the adjustment priority so that the tension on the facility is balanced.

[0014] Preferably, in step S1, before testing the tension of the tension rope, the preload of the wire rope is first adjusted by adjusting the adjusting screw of the wind load tension rope connecting to the ground anchor. Then, the wire rope tension testing device is installed, and the wire rope to be tested is alternately inserted into the positioning rollers and slots of the pulley groups on both sides. In step S3, the wire rope is affected by the pretension force, and the positioning rollers on both sides are pressed. The combined force on both sides forms an upward force. Under the influence of the upward force, the transmission rod drives the spring assembly to move upward. By adjusting the adjusting screw again, the plane line on the slot is displaced upward relative to the zero scale position. The scale line that coincides with the value on the tension data panel is the pretension force of the rope.

[0015] Preferably, in step S3, the adjustment strategy is set according to the following steps: A1. Setting parameters, the preload force detected by the drilling and workover wire rope tension testing device is: F n Where n is the number of the wire rope, the angle between each wire rope and the horizontal ground is α, and the total height of the facility is...

When the facility is self-balancing in the horizontal direction, T=0. Calculate the adjustment deviation of the tensioned wire ropes. ; A2. Priority indicators are defined based on the balance of facility levels. w1, w2, and w3 are the set weight coefficients, respectively. The objective function is to minimize the horizontal imbalance. ; A3. Prioritize adjusting P based on the priority of the indicator size. i For wire ropes with high tension values, adjust and recalculate the priority index until the tension of each wire rope is reached. .

[0016] The present invention has at least the following beneficial effects: The drilling and workover wire rope tension testing device of the present invention adopts a mechanical structure, abandoning the traditional tension sensor. Through the cooperation of mechanical transmission components, wire rope adapter mechanism and preset tension data panel, it can perform tension testing on various wire ropes in drilling and workover scenarios, such as wind load tension ropes, second-floor platform to ground tension ropes, internal load tension ropes, second-floor platform escape ropes, and safety ropes. The structure is simple and reliable, adaptable to a wide range of scenarios, easy to operate and low cost. It solves the problems of high cost and low reliability of traditional electronic testing devices at drilling and production sites. It is especially suitable for dense wire rope scenarios such as workover rigs without tension ropes. Furthermore, by utilizing the wire rope tension testing data, it integrates the installation angle, length and windward vertical area of ​​the wire rope connection facilities. For wire rope pretensioning at different locations, it calculates the pretensioning force based on the tensioning position, angle, height range and wind load resistance, designs the safe range of pretensioning force and adjustment strategy, realizes scientific control of wire rope tension, and effectively improves the safety and efficiency of workover operations.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0020] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] like Figure 1-3 As shown, firstly, the present invention provides a drilling and well workover wire rope tension testing device, comprising: A mechanical transmission assembly includes a positioning component 1, a sleeve 5, a handle 2, a transmission rod 3, and a spring assembly 4. The lower end of the positioning component 1 is provided with an installation space for testing the tension of a wire rope. The sleeve 5 is vertically connected to the upper middle part of the positioning component 1. The transmission rod 3 is coaxially inserted into the sleeve 5 and its upper end is limited by the sleeve 5. The lower end of the transmission rod 3 freely passes downward through the positioning component 1 and extends into the installation space. The spring assembly 4 is vertically sleeved on the outside of the transmission rod 3. The spring assembly 4 is set inside the sleeve 5 and is sleeved on the outside of the transmission rod 3 in a coaxial direction. One end of the spring assembly 4 is connected to the transmission rod 3. The handle 2 is used to adjust the height space inside the sleeve 5 along the axial direction of the sleeve 5 and to compress the spring assembly 4 for pre-tightening. The wire rope adapter mechanism includes a double pulley block 6 and an arc-shaped slot 7 set in the installation space. The slot 7 is connected to the bottom of the transmission rod 3. The double pulley blocks 6 are symmetrically arranged on both sides of the slot 7. The wire rope 12 to be tested passes through the upper end of one pulley block 6, the lower end of the slot 7 and the upper end of the other pulley block 6 in sequence along the same vertical plane to achieve alignment and fixation. A plane line is set on the upper end of the slot 7 along the horizontal direction. The tension data panel 13 is connected to the positioning component 1. The surface is preset with tension scales for the type of steel wire rope to be tested under different tensions. The direction of change of the tension scale is the same as the direction of movement of the plane line. The displacement of the plane line corresponds to the tension scale and displays the tension value. When the tension scale is 0, the spring assembly 4 is in a free state.

[0022] By setting up a wire rope adapter mechanism on the wire rope, the pulley block 6 and the slot 7 can be made according to the proportions and relative positions shown in the figure. The wire rope adapter mechanism is installed on the lower side of the mechanical transmission component, and the transmission operation is performed on the upper side. Before installation, the tension data panel and the plane line of the slot 7 are calibrated, and the size of the pulley and the slot 7 is set to adapt to wire ropes of various specifications such as 14mm, 16mm, 20mm, and 22mm. The scale of the tension data panel can be modularly designed. The panel can be replaced according to the wire rope specifications of different oil fields or equipment to adapt to the unique tension requirements. Keep the spring in a free state, and then align the plane line on the slot 7 with the "0" scale line on the panel.

[0023] Before measuring the tension of the tension rope, the preload of the wire rope is first adjusted by adjusting the adjusting screw of the wind load tension rope connecting to the ground anchor. Then, using a wire rope tension testing device, the wire rope to be tested is inserted between the upper side of the pulley group 6 on both sides and the lower side of the groove 7. At the same time, the wire rope is affected by the preload, and the pulleys on both sides are compressed. The combined force on both sides forms an upward force. Under the influence of the upward force, the pressure rod drives the spring group 4 to move upward, causing the upper plane of the groove 7 to shift upward relative to the zero point position. The scale line where the position of the upper plane of the groove 7 coincides with the value on the tension data panel is the preload of the tension rope. The tension data panel is equipped with multiple scale data lines and marking lines, and can distinguish the tension values ​​of different areas such as the tension rope from the crane to the derrick and the internal load tension rope.

[0024] The drilling and workover wire rope tension testing device adopts a mechanical structure, abandoning the traditional tension sensor. Through the cooperation of mechanical transmission components, wire rope adapter mechanism and preset tension data panel, it can perform tension testing on various wire ropes in drilling and workover scenarios, such as wind load tension ropes, second-level platform to ground tension ropes, internal load tension ropes, and second-level platform escape ropes. It has a simple and reliable structure, wide applicability, convenient operation and low cost, which solves the problems of high cost and low reliability of traditional electronic testing devices in drilling and production sites. It is especially suitable for dense wire rope scenarios such as workover rigs without tension ropes.

[0025] In another technical solution, such as Figure 1-3 As shown, the spring group 4 is a multi-stiffness spring parallel combination, containing at least two groups of springs with different elastic coefficients to improve the tensile force detection range.

[0026] In another technical solution, such as Figure 1-3 As shown, the positioning component 1 includes: The top support plate 8 is a flat plate structure with a through hole in the middle. The diameter of the through hole is not less than a certain value. The transmission rod 3 is freely slidably connected to the through hole. The sleeve 5 is coaxially connected to the upper side of the top support plate 8. The top support plate 8 has symmetrical holes to facilitate observation of the wire rope installation and tension status.

[0027] The corner brace 9 is a right-angled plate structure. One side is fixedly connected to the bottom of the top support plate 8, and the other side is used to connect and install the pulley block 6. The tension data panel is connected to the other side of the corner brace 9 facing the slot 7. The corner brace 9 leaves space for the installation and movement of the central transmission rod 3 and the slot 7.

[0028] In another technical solution, such as Figure 1-3 As shown, the sleeve 5 includes: The lower cylinder 10 has a connecting ring fixedly connected to its bottom outer side, which is fixedly connected to the top support plate 8. The upper outer side of the lower cylinder 10 is covered with an external thread along the axial direction. The upper cylinder 11 has a top cover that extends radially inward at its top. A through hole is provided in the middle of the top cover. The upper end of the transmission rod 3 passes through the through hole. A limiting groove is provided at the bottom of the top cover outside the through hole. The lower end of the upper cylinder 11 has an internal thread. The upper cylinder 11 and the lower cylinder 10 are connected by mutually mating internal and external threads. The handle 2 is connected to the upper end of the upper cylinder 11. The outer wall of the transmission rod 3 is connected to a limiting ring along the radial direction at the lower end of the inner side of the lower cylinder 10, and the spring assembly 4 abuts between the limiting ring and the limiting groove.

[0029] The external thread on the upper end surface of the lower cylinder 10 engages with the internal thread of the upper cylinder 11 of the connecting handle 2. The spring is limited between the limiting groove and the limiting ring, and only vertical movement occurs. It does not contact the inner wall of the sleeve 5. The compression spring is pre-tightened and installed by rotating the handle 2.

[0030] In another technical solution, such as Figure 1-3 As shown, it also includes a camera module, a power module, a central controller, and a support frame. The support frame is fixed on the drilling equipment or connected to the positioning component 1. The camera module is electrically connected to the power module and fixed on the support frame. The camera module is positioned facing the tensile data panel and the slot 7. The camera module is communicatively connected to the central controller to send the captured images to the central controller for analysis and display.

[0031] This wire rope tension testing device is adaptable to multiple locations and does not require traditional tension testing sensors, saving significant installation and replacement costs. It can also perform individual testing of multiple ropes. Through a central controller, it integrates all camera modules and sets up displays, data analysis modules, etc., enabling high-precision digital display, data recording, over-limit alarms, and remote transmission.

[0032] This invention also provides a method for applying a drilling and well workover wire rope tension testing device, comprising the following steps: S1. Establish a wire rope testing and control system. For each wire rope, calibrate the linear correspondence between the wire rope tension and the spring compression of the wire rope tension testing device under the corresponding specifications. Set the tension data panel and set the tension value control range for each wire rope. S2. After adjusting the preload, set up the wire rope tension testing device of the corresponding specification and align it with the zero mark on the tension data panel. S3. Real-time acquisition of tension data and tilt angle relative to the horizontal ground of all wire ropes under tension during operation, data analysis, comparison with the set tension value control range, setting adjustment strategies, and setting weights according to the tilt angle of the wire rope to form adjustment priorities; S4. For the wire rope whose tension value exceeds the control range in step S3, the adjustment mechanism is controlled to execute the adjustment strategy according to the adjustment priority so that the tension on the facility is balanced.

[0033] When testing the tension of wire rope, the inherent properties of the wire rope are integrated, and the pretension force of the wire rope at different positions is calculated based on the tension position, angle, and height range. The safe range of pretension force and adjustment strategy are designed to achieve scientific control of the wire rope pretension force.

[0034] In another technical solution, such as Figure 1-3 As shown, in step S1, before testing the tension of the tension rope, the preload of the wire rope is first adjusted by adjusting the adjusting screw of the wind load tension rope connecting to the ground anchor. Then, the wire rope tension testing device is installed, and the wire rope to be tested is alternately inserted into the positioning roller and the slot 7 of the pulley group 6 on both sides. In step S3, the wire rope is affected by the pretension force, and the positioning rollers on both sides are pressed. The combined force on both sides forms an upward force. Under the influence of the upward force, the transmission rod 3 drives the spring group 4 to move upward. By adjusting the adjusting screw again, the plane line on the slot 7 is displaced upward relative to the zero scale position. The scale line that coincides with the value on the tension data panel is the pretension force of the rope. This device can be adapted to multiple positions for wire rope tension testing and individual testing of multiple ropes.

[0035] In another technical solution, such as Figure 1-2 As shown, in step S3, the adjustment strategy is set according to the following steps: A1. Setting parameters, the preload force detected by the drilling and workover wire rope tension testing device is: F n Where n is the number of the wire rope, the angle between each wire rope and the horizontal ground is α, and the total height of the facility is... H z Each wire rope occupies a vertical height of h iThe projected area of ​​the facility in the vertical plane perpendicular to the vertical plane containing each steel wire rope is: s i The maximum vertical projected area of ​​the facility is S, and the horizontal balance condition for the facility under tension by steel wire rope is as follows: , F i For each horizontal component of force required for each wire rope, an adjustment threshold G is set for each horizontal component. When the facility is self-balancing in the horizontal direction, T=0. Calculate the adjustment deviation of the tensioned wire ropes. ; A2. Priority indicators are defined based on the balance of facility levels. w1, w2, and w3 are the set weight coefficients, respectively. The objective function is to minimize the horizontal imbalance. ; A3. Prioritize adjusting P based on the priority of the indicator size. i For wire ropes with high tension values, adjust and recalculate the priority index until the tension of each wire rope is reached. .

[0036] The influence of three core parameters affecting the wire rope preload is studied to determine their degree of influence. These parameters include the difference between the measured preload and the design value, the wire rope tension angle, the height of the connection to the facility, and the influence of wind. When the wind load is large, the value of w3 can be increased. Generally, w1=0.6, w2=0.3, and w3=0.1 can be set. For example, for an XJ550 workover rig, two symmetrical tension ropes are installed from the gantry crane to the frame with a preload of 728 kg; two symmetrical tension ropes are installed from the lower body to the frame with a preload of 485 kg; two symmetrical tension ropes are installed from the lower body to the foundation with a preload of 728 kg; two symmetrical tension ropes are installed from the gantry crane to the foundation with a preload of 485 kg; two symmetrical tension ropes are installed from the gantry crane to the drilling rig with a preload of 728 kg; and two symmetrical tension ropes are installed from the second-level platform to the drilling rig with a preload of 243 kg. The tension rope arrangement is based on the American Petroleum Institute (API) 4G guidelines for drilling and workover rig operation, inspection, maintenance, and repair. The wire rope with the highest priority index value is adjusted first. The adjustment value is calculated and adjusted according to ΔF. i The adjusting screw at the drive anchor adjusts the pre-tension of the wire rope, enabling the facility to reach force balance more quickly, eliminating safety risks, and allowing for targeted adjustments based on the site environment. The vertical plane where the inclined pre-tensioned wire rope is located is relatively perpendicular to the vertical plane. The projected area of ​​the facility within this vertical plane can be used as the area affected by the vertical wind load in real time. By using the relatively perpendicular wire rope as the most relevant adjustment object, the adjustment amount and impact of the wire rope can be reduced, improving the adjustment efficiency of the wire rope tension and facility safety.

[0037] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.

By adjusting the adjusting screw again, the plane line on the slot is displaced upward relative to the zero scale position. The scale line that coincides with the value on the tension data panel is the pretension force of the rope.

8. The application method of the drilling and well workover wire rope tension testing device as described in claim 6, characterized in that, In step S3, the adjustment strategy is set according to the following steps: A1. Setting parameters, the preload force detected by the drilling and workover wire rope tension testing device is: F n Where n is the number of the wire rope, the angle between each wire rope and the horizontal ground is α, and the total height of the facility is... H z Each wire rope occupies a vertical height of h i The projected area of ​​the facility in the vertical plane perpendicular to the vertical plane containing each steel wire rope is: s i The maximum vertical projected area of ​​the facility is S, and the horizontal balance condition for the facility under tension by steel wire rope is as follows: , F i For each horizontal component of force required for each wire rope, an adjustment threshold G is set for each horizontal component. When the facility is self-balancing in the horizontal direction, T=0. Calculate the adjustment deviation of the tensioned wire ropes. ; A2. Priority indicators are defined based on the balance of facility levels. w1, w2, and w3 are the set weight coefficients, respectively. The objective function is to minimize the horizontal imbalance. ； A3. Prioritize adjusting P based on the priority of the indicator size. i For wire ropes with high tension values, adjust and recalculate the priority index until the tension of each wire rope is reached. .
