Description

Technical Field

[0001] The utility model relates to the technical field of petroleum engineering, and in particular to a digital display testing device for a spring jar. Background Art

[0002] Spring jar is one of the main supporting tools for wireline operation. It is used to provide upward shock force in heavy-load fishing operations in vertical and inclined wells of oil fields. When pulled upward, the jar rod drives the connecting rod to overcome the spring force of the butterfly spring leaf and move upward through the claw. After a certain stroke, the connecting short section forces the claw to retract, so that the claw and the connecting rod are separated, thereby forming an impact force acting on the cylinder and transmitting it to the tool string. By adjusting the adjusting nut, different shock forces from low to high can be obtained, making the shock convenient and flexible. When casting and fishing downhole instruments and tools in oil production wells, jars are usually used in conjunction with wireline tool strings as a jamming tool. The rapid lifting and lowering of the wire over a limited distance drives the jar to generate an impact force on the tool string under the action of inertia, so that the downhole tools can be placed, fished, or unstuck. With the continuous expansion of the field of offshore oil production, the direction of offshore oil field production has gradually shifted to deep oil and gas reservoirs and high-temperature and high-pressure oil and gas reservoirs. The increasing complexity of well conditions has also brought huge challenges to wireline operations. Spring jars provide a technical basis for the smooth progress of wire rope operations with their superior performance and powerful shock force.

[0003] The force adjustment of existing spring jars is not precise enough. After the tool is lowered into the well, it is difficult to control the lifting speed and distance due to the influence of the speed of the wire winch and the conditions of the well itself. In addition, when the spring jar is adjusted on the ground, the adjustment force is not precise enough, and the wire is often overloaded and broken. Existing spring jar testing tools mainly rely on mechanical stretching and external tension gauge measurement, which will result in large errors, making it more difficult for the spring jar to work normally after being lowered into the well, thus causing quality accidents. The hydraulic detection device has large human errors. During the pressurization process of the hand pump, there are large individual differences, which makes the spring jar test value deviation large. Utility Model Content

[0028] Each workpiece is connected by thread, which is convenient for disassembly and installation.

[0029] like Figure 2 As shown, one end of the sensor 120 is connected to one end of the spring shocker 130, and the other end is connected to the second bed frame baffle 112, and the other side of the second bed frame baffle 112 is fixed to the sensor 120 by the hexagonal bolt 115; a connecting part 122 is arranged above the sensor 120, and the connecting part 122 is connected to the operating all-in-one machine 170 through a connecting line 121, so that the data measured by the sensor 120 is transmitted to the operating all-in-one machine 170 through the connecting line 121.

[0030] The sensor 120 is a device that converts the magnitude of force into a related electrical signal; the sensor 120 can detect mechanical quantities such as tension, pulling force, pressure, weight, torque, internal stress, etc.; specific devices of the sensor 120 include pressure sensors, etc., which are indispensable core components in power equipment, engineering machinery, various machine tools and industrial automation systems.

[0031] like Figure 3 As shown, the inner wall of the end 152b of the screw nut 152 connected to the screw 150 is provided with a thread (not shown in the figure), and the screw nut 152 is connected to the screw 150 by a thread; the outer wall of the end 152a of the screw nut 152 connected to the chain 161 is provided with a protrusion near the middle position, which is used to cooperate with the chain 161, so that when the reduction motor 160 rotates to drive the chain 161 to rotate, the chain 161 drives the screw nut 152 to rotate; the outer wall of the end 152a of the screw nut 152 connected to the chain 161 is provided with a thread (not shown in the figure) near the end, and is connected to the screw nut bolt 153 by a thread. The screw nut bolt 153 is used to limit the activity space of the chain 161 to prevent the chain 161 from deviating during movement, causing the chain 161 to separate from the protrusion, thereby causing the test failure.

[0032] like Figure 4 As shown, a gear 162 is provided at one end of the reduction motor 160, and the gear 162 is connected to the chain 161, so that when the reduction motor 160 rotates, the chain 161 is driven to move by the rotation of the gear 162, thereby driving the screw nut 152 to rotate, and then controlling the movement of the screw 150.

[0033] The reduction motor 160 is an integration of a reducer and a motor, and this integration is also generally referred to as a gear motor or a gear motor; the reduction motor 160 is a fixed-speed reduction motor, and once the speed ratio and the motor are selected, the final output speed is fixed; the reduction motor 160 can achieve the requirement of pulling open the spring jar 130 by setting a speed that meets the requirements, so that when the accelerator 140 is actuated, the spring jar 130 is displaced and vibrates, thereby obtaining more accurate test data.

[0034] like Figure 5 As shown, the operating machine 170 is designed as a touch screen, and a display screen 171 is arranged on the upper part of the operating machine 170. The operating machine 170 is connected to the reduction motor 160 and the sensor 120 respectively; the operating machine 170 controls the speed, pulling force, etc. of pulling the spring jar 130 by controlling the reduction motor 160; the operating machine 170 is connected to the sensor 120 through the connecting line 121. When the spring jar 130 is working, the sensor 120 directly transmits the measured shock force data of the spring jar 130 to the display screen 171 through the connecting line 121, so that the test data is accurate and the operation is simple.

[0035] After the reduction motor 160 is powered on, the gear 162 of the reduction motor 160 is controlled to rotate forward through the operating integrated machine 170, thereby driving the chain 161 to rotate forward. The lead screw nut 152 rotates clockwise driven by the chain 161. At this time, the lead screw nut 152 rotates, and the lead screw 150 moves to the left, driving the accelerator 140 to act, causing the spring jar 130 to displace and vibrate, and transmitting the shock force generated by the vibration to the sensor 120. The sensor 120 transmits the actual shock force data to the operating integrated machine 170 through the connecting line 121, so that the test force value and the displacement value of each workpiece are digitally displayed on the display screen 171 of the operating integrated machine 170. The gear 162 of the reduction motor 160 is controlled to reverse through the operating integrated machine 170, thereby driving the chain 161 to reverse. The lead screw nut 152 rotates counterclockwise under the drive of the chain 161. At this time, the lead screw nut 152 rotates, and the lead screw 150 moves to the right. After the accelerator 140, the spring jar 130 and other workpieces are reset, a round of testing is completed.

[0036] The digital display test device for spring jar provided by the utility model controls the rotation speed of the reduction motor through the operation all-in-one machine by using an electronic system, thereby accurately stretching the spring jar, making the pulling force in the test process more accurate and avoiding test errors caused by human differences; the force measuring end detects the jarring force by using a high-precision pressure sensor, making the reading of the test data more accurate, and the sensor transmits the test data obtained by the test to the operation all-in-one machine through a connecting line, and directly displays the test value on the display screen of the operation all-in-one machine, so that the test value is digitally reflected, and the test value is more intuitively understood, and the operation is simple; the digital display test device for spring jar provided by the utility model has a wide range of applications, can accurately test the jarring force of the spring jar, and provides a safer and more reliable technical guarantee for the debugging of the spring jar, which provides a basis for the normal operation of the spring jar, and also provides a guarantee for underground heavy-load salvage operations.

It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
