Background
The sucker rod, the oil pipe and the downhole tool are three basic components in an oil production well of an oil field, and in practical use, the sucker rod, the oil pipe and the downhole tool need to be checked and recorded before each downhole so as to master the abrasion and the use condition of each sucker rod, each oil pipe and each set of downhole tool. At present, the checking and recording work of the equipment is completed by manual operation of workers, the field checking and recording process is time-consuming and labor-consuming in the mode, a large amount of recorded data needs to be manually recorded into a computer for storage in the later period, and the workload is large. For this reason, technicians have developed a system for tracking devices such as sucker rods, oil pipes, and downhole tools by radio frequency identification technology, and it is necessary to implant chips in the devices such as sucker rods, oil pipes, and downhole tools. In the prior art, all chips are implanted into equipment in a resin packaging mode, but the safety of the chips is not easy to guarantee in a high-pressure underground environment. In addition, the chip is easily damaged in a high-temperature environment in the pit, and the chip is difficult to replace in a resin packaging mode.
SUMMERY OF THE UTILITY MODEL
The utility model provides a chip mounting structure for on sucker rod, oil pipe coupling and the downhole tool to solve the problem of proposing among the above-mentioned background art.
The utility model provides a technical problem adopt following technical scheme to realize: the utility model provides a chip mounting structure for on sucker rod, oil pipe coupling and downhole tool, including step hole, sealing plug, sealing ring, plug and screw, the sealing plug passes through the transition fit cartridge in the shoulder hole, the sealing ring press from both sides between the outer wall of sealing plug and the inner wall of shoulder hole, the outside of sealing plug and the inboard of shoulder hole correspond with the both sides of sealing ring and are provided with a step, and the root of step respectively is provided with a recess, the sealing plug inserts the in-process of shoulder hole, the sealing ring quilt of being made by soft metal two steps extrusion deformation after fill up the recess of step root to the sealing plug firmly installs in the shoulder hole.
The center of the sealing plug is provided with a balance hole, the outer end of the balance hole is provided with a threaded hole section, the screwed plug is connected in the threaded hole section through threads and completely does not exist in the threaded hole section, and the screw is screwed in the threaded hole section; the minimum diameter of the balance hole is not more than 2 mm; the balance hole is internally provided with a sealing gasket, the front end of the screwed plug is provided with a conical surface matched with the sealing gasket, and the conical surface is tightly pressed on the sealing gasket so as to seal the balance hole.
The sealing ring is made of pure copper.
The utility model has the advantages that:
1. the utility model changes the existing chip packaging mode, on one hand, the sealing ring made of soft metal is used for sealing, thereby ensuring the reliable sealing of the chip; on the other hand, through setting up the balancing hole, can be at the inside and outside pressure of the sealed ring by extrusion in-process balanced chip place cavity, prevent that the chip from bearing the pressure that compressed air brought, avoid the chip to damage.
2. The utility model discloses set up the screw hole on the sealing plug, under the user state, do not install the screw, when changing the chip, twist the screw into the screw hole section, then use tool draws the screw alright extract the sealing plug to swiftly change the chip.
Drawings
FIG. 1 is a schematic view of the sucker rod coupling of the present invention;
fig. 2 is a schematic structural diagram of the present invention.
In the figure, 1-a tubing coupling, 2-a sealing ring, 3-a plug, 4-a sealing plug, 5-a screw, 6-a sealing gasket, 7-a balance hole, 8-a chip, 9-a step and 10-a groove.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
the embodiment comprises a step hole, a sealing plug 4, a sealing ring 2, a plug 3 and a screw 5, wherein the step hole is processed on the end face of a sucker rod, a tubing coupling or an underground tool, and the collision or abrasion in the underground operation process is prevented.
The sealing plug 4 is inserted into the stepped hole through transition fit, certain connection strength can be guaranteed under the condition of no connection structure through the transition fit, and meanwhile, the sealing plug 4 can be guaranteed to be detachable.
The sealing ring 2 is clamped between the outer wall of the sealing plug 4 and the inner wall of the stepped hole, the outer side of the sealing plug 4, the inner side of the stepped hole and two sides of the sealing ring 2 are respectively and correspondingly provided with a step 9, the root parts of the steps 9 are respectively provided with a groove 10, in the process that the sealing plug 4 is inserted into the stepped hole, the sealing ring 2 made of soft metal is extruded and deformed by the two steps 9 and then fills the groove 10 at the root part of the step 9, so that the sealing plug 4 is firmly installed in the stepped hole, and the material of the sealing ring 2 can be pure copper. In the structure, the extruded sealing ring 2 can be tightly attached to the outer wall of the sealing plug 4 and the inner wall of the stepped hole, so that the gap between the sealing plug 4 and the inner wall of the stepped hole is sealed, and the sealing reliability is extremely high.
The center of the sealing plug 4 is provided with a balance hole 7, and the balance hole 7 can balance the internal pressure and the external pressure of a cavity where the chip 8 is located in the process that the sealing ring 2 is extruded, so that the chip 8 is prevented from bearing the pressure caused by compressed air, and the chip 8 is prevented from being damaged.
After the sealing plug 4 is installed, the balance hole needs to be plugged specifically in the following way:
the outer end of the balance hole 7 is provided with a threaded hole section, the screwed plug 3 is connected in the threaded hole section through threads and completely does not exist in the threaded hole section, a sealing gasket 6 is arranged in the balance hole 7, the front end of the screwed plug 3 is provided with a conical surface matched with the sealing gasket 6, and the conical surface is tightly pressed on the sealing gasket 6, so that the balance hole 7 is sealed. In the implementation process, in order to prevent the screw plug 3 from being unscrewed, thread glue can be coated on the threaded connection part.
The screw 5 is screwed in the threaded hole section, the screw 5 is not installed in the use state, when the chip 8 is replaced, the screw 5 is screwed in the threaded hole section, and then the sealing plug 4 can be pulled out by pulling the screw 5 by using a tool, so that the chip 8 is replaced quickly.
The minimum diameter of the balance hole 7 is not more than 2mm, and the smaller the diameter is, the smaller the sealing difficulty is. In practice, the diameter of the balance hole 7 is too small to be processed by drilling, and laser drilling can be adopted for processing.
