Description

Technical Field

[0001] This utility model relates to the field of quality inspection, specifically to a perforation quality inspection device for the perforation pattern of a perforator magazine tube. Background Technology

[0002] A perforator clip is a piece of equipment used in oil and gas well drilling. It is mainly used to create channels in the rock mass and establish a communication channel between the formation and the wellbore so that reservoir fluids can enter the wellbore, thereby enabling normal production of oil and gas wells. The side hole diameter of the perforator clip changes with the size of the perforator clip. In order to detect the size of the side hole of the perforator clip, a special perforator clip hole shape quality inspection device is usually used to inspect it.

[0003] The existing perforator cartridge tube hole shape quality inspection device mainly consists of a base, a detachable slide block, a detection component, and a height adjustment component. The appropriate detachable slide block is selected according to the diameter of the perforator cartridge tube. After the detachable slide block is slid into the slide in the base, it is aligned with the center of the side hole of the perforator cartridge tube and the detection component. The height adjustment component is controlled to press down, so that the detection component enters the side hole of the perforator cartridge tube. The hole shape data is measured by the detection component.

[0004] When the height adjustment component is pressed down, in order to prevent the detection component from pressing against the outer wall of the perforator magazine tube, it is necessary to manually calibrate the position of the side hole of the perforator magazine tube and the bottom surface of the detection component. After measurement, the height adjustment component is pressed down to measure the hole shape of the side hole of the perforator magazine tube. This calibration relies entirely on the experience of the testing personnel. If a side hole of a perforator magazine tube is not calibrated in time, or if the deviation is too large after calibration, measurement errors will occur, or even damage to the detection component. Utility Model Content

[0005] The technical problem this invention aims to solve is that in existing perforator clip tube hole type quality inspection devices, the calibration of the side hole of the perforator clip tube and the bottom surface of the detection component can only be performed manually based on experience.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a hole shape quality inspection device for a perforator cartridge tube, including a base, a plurality of detachable sliding blocks passing through the base, a perforator cartridge tube located in the arc groove of the detachable sliding blocks, and a detection component for detecting the hole shape of the perforator cartridge tube, wherein a height adjustment component for controlling the height of the detection component is provided above the detection component.

[0007] The bottom cavity of the detection component is equipped with a laser positioner, and the outer wall of the laser hole of the laser positioner is equipped with a positioning telescopic sleeve. The outer wall of the aperture measuring end of the detection component is equipped with a resistance sensing device.

[0008] As an improvement, a spring telescopic assembly is provided between the height adjustment assembly and the detection assembly, and the spring telescopic assembly includes a telescopic sub-rod welded to the top surface of the detection assembly, a mother rod corresponding to the telescopic sub-rod, and a pressure spring located between the telescopic sub-rod and the mother rod.

[0009] As an improvement, the height adjustment assembly includes a positioning slider located above the main rod, a plurality of positioning slide rods passing through the side of the positioning slider, and a height telescopic device fixed between the base and the positioning slider.

[0010] As an improvement, the top of the positioning slider is equipped with an indicator light to show whether the perforation pattern of the cartridge tube is qualified.

[0011] As an improvement, the bottom surface of the detachable slide block is provided with an I-shaped slider that passes through the base.

[0012] As an improvement, a limiting block is provided above the resistance sensing device of the detection component to restrict the detection component from falling further.

[0013] The advantages of this invention compared to the prior art are as follows: This device installs a laser positioner on the bottom surface of the detection component, and the positioning telescopic sleeve below the laser positioner ensures that the laser positioner will not be damaged by pressure. The outer wall of the detection component uses a resistance sensing device to detect the size of the aperture. When the aperture is too small, part of the resistance sensing element cannot be squeezed by the inner wall of the aperture, resulting in a smaller resistance. Similarly, when the aperture is too large, the resistance of the resistance sensing element will not fluctuate. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As per the instruction manual Figure 1 , 2 As shown in Figure 4, the device includes a base 1, several detachable sliding blocks 2 passing through the base 1, a perforator cartridge tube 3 located in the arc groove of the detachable sliding blocks 2, and a detection component 4 for detecting the hole shape of the perforator cartridge tube 3. A laser locator 41 is provided inside the bottom cavity of the detection component 4, and a positioning telescopic sleeve 42 is provided on the outer wall of the laser hole of the laser locator 41. A resistance sensing device 43 is provided on the outer wall of the hole diameter measuring end of the detection component 4. An indicator light 511 indicating whether the hole shape of the perforator cartridge tube 3 is qualified is provided at the top of the positioning slider 51. A limit block 431 is provided above the resistance sensing device 43 of the detection component 4 to restrict the further descent of the detection component 4. Before the detection component 4 itself falls, the center of the side hole of the perforator cartridge tube 3 is aligned with the laser line of the laser locator 41 to ensure the positioning of the bottom surface of the detection component 4. The telescopic sleeve 42 can be inserted into the side hole of the perforator magazine tube 3 without obstruction. In addition to ensuring that the laser positioner 41 is not damaged, the positioning telescopic sleeve 42 also avoids direct contact between the detection component 4 and the outer wall of the perforator magazine tube 3, thus ensuring that the outer wall of the perforator magazine tube 3 is not damaged. The size of the side hole of the perforator magazine tube 3 is determined by the change of the resistance sensing device 43. When the resistance of the resistance sensing device 43 remains unchanged or the local resistance increases, the failure indicator light 511 will be triggered. Similarly, when the resistance sheet is fully compressed and the resistance changes across the board, the success indicator light 511 will be triggered. At the same time, in order to prevent the positioning telescopic sleeve 42 from being squeezed on the perforator magazine tube 3 due to the excessively large aperture, a limit block 431 is usually installed above the resistance sensing device 43 to limit the falling distance of the detection component 4.

[0021] As per the instruction manual Figure 1 , 2As shown in Figure 3, a spring telescopic assembly 6 is provided between the height adjustment assembly 5 and the detection assembly 4. The spring telescopic assembly 6 includes a telescopic sub-rod 61 welded to the top surface of the detection assembly 4, a mother rod 62 corresponding to the telescopic sub-rod 61, and a pressure spring 63 located between the telescopic sub-rod 61 and the mother rod 62. In order to ensure that when detecting perforator cartridge tubes 3 of different diameters, the large diameter has been measured but the small diameter has not been detected, the spring telescopic assembly 6 is welded above the detection assembly 4. The pressure spring 63 between the telescopic sub-rod 61 and the mother rod 62 ensures that the large diameter detection assembly 4 will not damage the perforator cartridge tube 3 when it is continuously pressed down.

[0022] Above the detection component 4 is a height adjustment component 5 for controlling the height of the detection component 4. The height adjustment component 5 includes a positioning slider 51 located above the mother rod 62, several positioning slide rods 52 passing through the side of the positioning slider 51, and a height telescopic device 53 fixed between the base 1 and the positioning slider 51. The bottom surface of the detachable slide block 2 is provided with an I-shaped slider 21 passing through the base 1. The bottom surface of the mother rod 62 is fixed to the bottom surface of the positioning slider 51 using screws. Then, two positioning slide rods 52 are passed through the internal through holes of each positioning slider 51, and the two height telescopic devices 53 are simultaneously... 3. The bottom surfaces of the two positioning sliders 51 at the outermost end are welded together, and the two height telescopic devices 53 are placed on both sides of the detachable slide block 2 and fixed to the base 1 with screws. By sliding the positioning sliders 51 and the positioning slide rods 52 against each other, the detection component 4 can be aligned with the center point of the side hole of the perforator cartridge tube 3 at all times. At the same time, the detachable slide block 2 is made into a detachable structure and is fixed in direction with I-shaped sliders 21 to ensure that any size perforator cartridge tube 3 can independently select the appropriate detachable slide block 2 and ensure that there is no vibration during the detection process.

[0023] In practical implementation, this invention selects a suitable detachable sliding block 2 according to the size of the perforator cartridge tube 3, and slides the I-shaped slider 21 into the internal through hole of the base 1. Then, the positioning slider 51 is slid to make the top of the side hole of the perforator cartridge tube 3 coincide with the center of the detection component 4 above. Then, the laser positioning device 41 is activated so that it passes through the side hole of the perforator cartridge tube 3, ensuring that the positioning telescopic sleeve 42 does not press against the outer wall of the side of the perforator cartridge tube 3 when pressed down. Then, the height telescopic device 53 is activated to press down and inspect each perforator cartridge tube 3. The indicator light 511 is used to determine whether the side hole of the perforator cartridge tube 3 is qualified. If it is qualified, the perforator cartridge tube 3 is rotated to measure the side hole of the next perforator cartridge tube 3. If it is unqualified, it is directly rejected.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
