[0002] In the field of oilfield logging, most of the Martindales used for measuring the running depth of logging cables and the tension meters used for measuring the tension of logging cables are separate measuring instruments. The logging tension meters can generally be divided into two categories according to their models: pulley tension meters and Martindale tension meters. Among them, the installation of the pulley tension meter has nothing to do with the type of cable, while due to the particularity of its working principle, the Martindale tension meter needs to consider the diameter of the cable. However, the existing Martindale tension meters are not universal and cannot adapt to the tension measurement of different types of logging cables. Therefore, for different types of cables, different types of Martindale tension meters need to be configured, which increases the operating cost and reduces the work efficiency.

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.
[0026] Please refer to Figures 1 - 5, an embodiment of the present application provides a logging tension meter with adjustable measurement angle applicable to multiple models of cables, including a measurement mechanism 1 for installing a logging cable to measure the cable tension, an adjustment component 2 for adjusting the measurement angle, and a driving mechanism 3 for controlling the adjustment component 2. The adjustment component 2 is installed on the measurement mechanism 1, and the driving mechanism 3 is arranged on the adjustment component 2 and can drive the adjustment component 2 to adjust the middle bending angle of the logging cable installed by the measurement mechanism 1 during cable tension measurement.
[0027] Among them, the measurement mechanism 1 includes a first mounting bracket 101, a second mounting bracket 102, a tension meter 103, a first fixing screw 104, a first fixing shaft 105, a second fixing shaft 106, and a measurement wheel group composed of a tension wheel 107 whose vertical height position can be adjusted and two fixed wheels 108 symmetrically distributed on both sides and below the tension wheel 107.
[0028] Specifically, as Figure 2 shown, the second mounting bracket 102 is located in front of the first mounting bracket 101 and is fixedly connected to the first mounting bracket 101 through the first fixing screw 104, so that the second mounting bracket 102 and the first mounting bracket 101 are fixedly connected as a whole, leaving a space for placing the measurement wheel group and the adjustment component 2 therebetween. The adjustment component 2 is detachably installed between the first mounting bracket 101 and the second mounting bracket 102, which is convenient for disassembling the adjustment component 2 and maintaining the device. The tension wheel 107 is connected below the adjustment component 2, and the tension wheel 107 can move up and down under the control of the adjustment component 2. The tension meter 103 is installed on the tension wheel 107 to measure the cable tension. A first fixing shaft 105 extending forward is installed on the first mounting bracket 101, and a second fixing shaft 106 extending backward is installed on the second mounting bracket 102. A fixed wheel 108 is respectively installed on the first fixing shaft 105 and the second fixing shaft 106 through bearings, which can rotate flexibly. The tension wheel 107 can move vertically up and down under the control of the adjustment component 2 to change the included angle with the two fixed wheels 108, so that the logging cable between the two fixed wheels 108 and on the fixed wheels 108 presents a certain included angle, that is, the measurement angle. During actual measurement, in order to ensure the measurement accuracy, the measurement angle is usually controlled at 177°. For the use of different specifications and models of cables by conventional logging tension meter devices, the adaptability is poor, and the measurement angle will change due to the installation of different specifications and models of cables. Since the present application can quickly adjust the measurement angle by moving the tension wheel 107, it has strong application value. When in use, the data measured by the tension meter 103 installed on the tension wheel 107 and the measurement angle are used to obtain the tension of the installed cable. Optionally, lubricating oil channels are provided on the first fixing shaft 105 and the second fixing shaft 106 to facilitate lubricating the bearings.
[0029] The logging tension meter provided by the embodiment of the present application with adjustable measurement angle is applicable to logging cables of multiple models, has a compact structure and reasonable design. By installing an adjustment component 2 on the measurement mechanism 1 and using a drive mechanism 3 to drive the adjustment component 2, the height position of the tension wheel 107 in the vertical direction can be changed, so as to adapt to the installation of logging cables of different models without replacing the logging tension meter, improve the replacement and installation efficiency of logging cables of different models, and is convenient to use; moreover, while realizing the installation of logging cables of different models, by further adjusting the adjustment component 2 to change the relative height position of the tension wheel 107 relative to the two fixed wheels 108, the bending condition of the middle part of the logging cable installed on the tension wheel 107 and the two fixed wheels 108 can be changed during cable tension measurement, so as to adjust the included angle between the tension wheel 107 and the two fixed wheels 108 to a suitable state for convenient measurement of cable tension.
[0030] During use, when the logging cable is installed on the logging tension meter provided by the present application with adjustable measurement angle applicable to multiple models of cables, the logging cable forms an angle under the combined action of the two fixed wheels 108 and the tension wheel 107. By adjusting the adjustment component 2, the tension wheel 107 moves to the corresponding position during the downward movement, so that the angle formed by the cable reaches a suitable state, such as adjusting the measurement angle to 177°. At this time, the two ends of the cable are stressed, and the cable gives an upward force to the tension wheel 107. The tension meter 103 is installed on the tension wheel 107, and the force is detected through the tension meter 103, and then the force on the cable is measured.
[0031] As an optional mode of the embodiment of the present application, such as Figure 3As shown in the figure, the adjusting assembly 2 includes a slider 201, a lead screw 202, a fixed block 203 and a mounting bracket 204. Mounting brackets 204 are arranged on the front and rear sides below the fixed block 203 for connecting to the first mounting bracket 101 and the second mounting bracket 102. In this embodiment, the mounting bracket 204 is simultaneously connected to the bottom ends of the first mounting bracket 101 and the second mounting bracket 102 through second fixing screws 2041, facilitating the disassembly and installation of the adjusting assembly 2. The fixed block 203 has a chute 2031 with an opening facing downward and in a U shape, and a vertically movable slider 201 is slidably connected in the chute 2031. A tension wheel 107 is rotatably installed in the slider 201, such that when the slider 201 moves up and down, the tension wheel 107 also moves up and down accordingly. In the embodiment of the present application, openings extending to the bottom end of the fixed block 203 and communicating with the chute 2031 are respectively formed on the left and right sides of the fixed block 203, so that the tension wheel 107 is not obstructed when it is lifted within a certain range. The top end of the slider 201 is rotatably connected to a lead screw 202. The top end of the lead screw 202 extends outside the top end of the fixed block 203. The lead screw 202 can rotate bidirectionally under the drive of the drive mechanism 3 to drive the slider 201 to move up and down in the chute 2031.
[0032] During use, after the drive mechanism 3 is started, the lead screw 202 rotates and lifts under the drive of the drive mechanism 3, thereby driving the connected slider 201 to move up and down, and further causing the tension wheel 107 on the slider 201 to move up and down as well, thus changing the angle of tension measurement.
[0033] As an optional mode of the embodiment of the present application, a drive mechanism 3 is arranged on the top side of the fixed block 203, such as Figure 3As shown in the figure, the driving mechanism 3 includes a motor 301, a speed reduction mechanism 302, a motor bracket 303, and a control panel 304. The motor bracket 303 is installed on the top side of the fixed block 203. The motor 301 is fixedly installed on the motor bracket 303. The control panel 304 is installed on the motor 301. The motor 301 is electrically connected to the control panel 304 and is controlled by the control panel 304 to rotate clockwise or counterclockwise. A lead screw nut 2021 with teeth on the outside is sleeved on the lead screw 202 above the fixed block 203. The lead screw nut 2021 meshes with the speed reduction mechanism 302. The output shaft of the motor 301 is connected to the speed reduction mechanism 302 and drives the lead screw nut 2021 to rotate by driving the speed reduction mechanism 302. In the embodiment of the present application, the speed reduction mechanism 302 is a multi-stage reduction gear set. After the motor 301 is started, the multi-stage reduction gear set of the speed reduction mechanism 302 operates. The gears are reduced by the speed reduction mechanism 302, and then drive the lead screw nut 2021 meshing with the reduction gear set to rotate, thereby realizing the lifting movement of the lead screw 202, and thus moving the tension wheel 107 to the corresponding position. During use, the control panel 304 is externally powered, and the forward and reverse rotation and the rotation position of the motor 301 can be controlled through the control panel 304. In practical applications, according to different models of the logging cables to be installed, a controller for conveniently and accurately controlling the motor 301 can be added to the control panel 304 to meet the requirement that the tension wheel 107 is moved to a suitable position after different models of logging cables are installed, so that different models of logging cables can accurately realize the automatic control of the measurement angle.
[0034] In some embodiments of the present application, the second mounting bracket 102 and the first mounting bracket 101 are arranged staggered front and back. A fixed wheel 108 is provided on each of the left side of the first mounting bracket 101 and the right side of the second mounting bracket 102. The fixed wheel 108 mounted on the first mounting bracket 101 is not blocked by the second mounting bracket 102 after installation, and the fixed wheel 108 mounted on the second mounting bracket 102 is not blocked by the first mounting bracket 101 after installation. The embodiment of the present application adopts the method of arranging the second mounting bracket 102 and the first mounting bracket 101 staggered front and back for connection, so that the left part of the second mounting bracket 102 and the right part of the first mounting bracket 101 overlap, enabling one side of the front and back sides of the two fixed wheels 108 not to be blocked after installation, facilitating the disassembly, assembly and maintenance of the fixed wheels 108, and also providing convenience for the installation of the cable.
[0035] In some embodiments of the present application, the installed logging cable is wound around the measurement wheel set in a directional manner in the order of the fixed wheel 108 on one side, the tension wheel 107, and the fixed wheel 108 on the other side. The lower wheel groove of the tension wheel 107 abuts against the logging cable, and the upper wheel grooves of the two fixed wheels 108 abut against the logging cable; the height positions of the two fixed wheels 108 are the same and the distances from the tension wheel 107 are equal. During use, in order to make the cable easier to install, the tension wheel 107 can be lifted a certain distance by adjusting the adjustment assembly 2 first. In the embodiment of the present application, the extreme position after the tension wheel 107 is lifted is the position where it is located when the top end of the slider 201 contacts the top end of the chute 2031. This position can be used as the initial position of the tension wheel 107. Taking this position as a reference, it is convenient to control the distance when the tension wheel 107 moves downward through the control panel 304. Under the condition of ensuring that the cable is completely placed into the measurement wheel set, the tension wheel 107 should be gradually moved downward by adjusting the adjustment assembly 2 at the same time, so that the cable is tightly placed into the lower wheel groove of the tension wheel 107. After adjustment, the cable parts on both sides of the lower wheel groove of the tension wheel 107 are slightly lifted upward to form a measurement angle.
[0036] As an optional method in the embodiment of the present application, the adjustable measurement angle provided by an embodiment of the present application is applicable to logging tension meters for multi-type cables, such as Figure 4 shown, and further includes a wheel groove rolling assembly 5 located below the tension wheel 107 and connected to the first mounting bracket 101 and the second mounting bracket 102. The wheel groove rolling assembly 5 can be located in the lower wheel groove of the tension wheel 107 during the measurement of the cable tension of the logging cable and rollingly contact the lower wheel groove of the tension wheel 107 and the logging cable in the lower wheel groove of the tension wheel 107. In the embodiment of the present application, by setting the wheel groove rolling assembly 5, the wheel groove rolling assembly 5 can be used to rollingly contact both the lower wheel groove of the tension wheel 107 and the cable at the same time. In this way, the cable can be prevented from wearing the tension wheel 107, and the decrease in measurement accuracy caused by long-term use can be avoided.
[0037] Refer to Figure 4 and Figure 5, wherein, the wheel groove rolling assembly 5 includes two fixed rods 501, two elastic rubber cords 502 and a plurality of rolling elements 503. Two parallel elastic rubber cords 502 are fixedly connected between the two fixed rods 501, and a plurality of rolling elements 503 are threaded through the two elastic rubber cords 502. Each rolling element 503 is composed of a rotating shaft 5031 and a roller 5032 rotatably connected to the rotating shaft 5031. The two ends of the rotating shaft 5031 are respectively threaded through the two elastic rubber cords 502. The two fixed rods 501 are symmetrically distributed on the left and right sides of the tension wheel 107. The two ends of the two fixed rods 501 are respectively fixedly connected to the first mounting bracket 101 and the second mounting bracket 102 and can suspend the rolling elements 503 below the tension wheel 107. In this way, when installing the logging cable, the cable at the tension wheel 107 can first contact the roller 5032 of the wheel groove rolling assembly 5, and then contact the lower wheel groove of the tension wheel 107 through the roller 5032. Adopting the form of the wheel groove rolling assembly 5 in the embodiment of the present application will not only not affect the normal operation of the tension wheel 107, but also will not hinder the installation of the cable. Moreover, by threading the rolling elements 503 through the two elastic rubber cords 502, it can better adapt to the wheel groove structure of the tension wheel 107 and fit with the wheel groove during use.
[0038] Optionally, the roller 5032 is of an ellipsoidal structure. By adopting the ellipsoidal roller 5032, it can not only greatly reduce the space occupied by the roller 5032 in the depth direction of the lower wheel groove of the tension wheel 107 to ensure the normal installation of the cable while ensuring the normal rolling of the roller 5032, but also better adapt to the wheel groove through the ellipsoidal structure of the roller 5032 to ensure that it will not get stuck in the wheel groove under the condition of good rolling.
[0039] In some embodiments of the present application, third fixing screws 4 are respectively provided on the first mounting bracket 101 and the second mounting bracket 102. During use, the logging tension meter provided by the present application can be fixed in front of or behind the Martin-Decker logging mechanism by using the third fixing screws 4 to measure the tension.
[0040] In some embodiments of the present application, an anti-skid plate 6 is rotatably arranged on the first mounting bracket 101. When installing the cable, the anti-skid plate 6 can be rotated first to open the anti-skid plate 6, and then the cable to be installed is laterally placed in the upper groove of the fixed wheel 108 on the second mounting bracket 102. Then, the cable is wound around the lower groove of the tension wheel 107, and finally, it is placed in the upper groove of the fixed wheel 108 on the first mounting bracket 101. The gaps between the first mounting bracket 101, the second mounting bracket 102 and the measuring wheel set can meet the passing of logging cables of different specifications and models during installation. After the cable is initially installed, the control panel 304 is controlled according to the installed cable model, and the motor 301 drives the tension wheel 8 to automatically adjust to the corresponding position to complete the rapid installation of the cable.
[0041] In some embodiments of the present application, the tensiometer 103 is an axial tensiometer, and the tensiometer 103 is coaxially installed on the tension wheel 107 through a bearing. The tensiometer 103 in the embodiments of the present application adopts an axial tensiometer, which is convenient for replacing tensiometers of different models.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
