Description
Technical Field
The utility model relates to a RFID label technical field especially relates to a RFID label of oil drill pipe.
Background
The UHF RFID petroleum drill pipe management tag is a tag special for the petroleum field and is composed of high-strength steel and polymers. Are specifically designed to be embedded in the bore of a drill pipe joint to track each individual pipe. RFID technology is critical to the task of accomplishing data tracking and capture on individual pipes that was previously impossible. Before using RFID technology, oil drilling companies often face several problems. They do not know exactly where the drill bit is, how it is used, and how long it is used. During drilling, the drill rods used to structure the rig units are stored on the stands of the rig or on the stands of the pipe field. In order to find the correct component of the drill string in the rig, the worker often needs to climb onto the drill string rack and measure the drill pipe with a tape measure. Then, the worker writes the specification on a piece of paper, and then manually inputs the data into the computer. In some cases, they may also paint identification numbers on the drill pipe, but because the use environment of the drill pipe is harsh, the paint may wear out in a short time, resulting in failure of the identification.
The ability to track individual joints of drill pipe using RFID technology opens up new possibilities for improved documentation and process efficiency, thereby saving costs and reducing risks. During tripping operations, the drill pipe is exposed to high temperatures, extreme pressure and vibration, as well as chemical corrosion. Therefore, the designed RFID petroleum drill rod tag needs to be capable of reliably bearing the underground high pressure environment and is used for recording important information such as the ID number, the steel number, the size and the weight of the drill rod, production information, final use condition, asset maintenance record and the like. The stored information is transmitted to the RFID tracking system. By using a handheld RFID reader, personnel can obtain critical information before and after scanning all drill pipes and can gain real-time visibility when assets need to be inventoried and maintained, and when they need to be scrapped. This greatly reduces the risk of leakage and rupture accidents that may lead to detection failure. By collecting raw data in time, the management layer can make rapid and accurate decisions using field data.
Some labels exist in the market, the labels are formed by encapsulating epoxy resin glue in an engineering plastic shell and curing, and ceramic labels are encapsulated in the plastic shell and then installed in hole sites in a metal drill rod in an embedded mode. However, the tag has short reading distance and is not impact-resistant, and the ceramic material is easy to damage by impact in the practical application process. The packaging material of the packaging process is easy to age in the using process, the service life of the packaging material is quickly attenuated in a high-temperature and high-pressure application environment, and the using failure rate of the label after the label is put into a well is too high.
After the improvement, a class of RFID tags appear in succession, adopt the embedded installation of stainless steel to FR4 circuit board is as antenna Patch face, and the stainless steel is as GND face, makes the label form microstrip antenna structure through the riveting, and the stainless steel inslot intussuseption is filled with engineering plastics PEEK that has higher environmental suitability, makes the label incorruptibility promote. The chip adopts a packaging piece, and the chip and the PATCH surface chip are welded at the position by a wave soldering SMT process, so that the QFN packaging piece, the antenna PATCH surface and the stainless steel shell integrally form a micro-strip structure anti-metal label, and the label can be suitable for the use environment of the drill rod. However, the reliability of the riveting process in the application process of the drill rod is reduced, and when the riveting is loosened, the phenomenon of poor contact between the Patch surface and the Gnd surface occurs, so that the performance of the label is attenuated and even the label is failed. Meanwhile, the stability of the FR4 board can be affected when the FR4 board works for a long time under the environment of high temperature, high pressure and high humidity, so that the performance of the label is affected, and the situation of poor consistency occurs. The microstrip structure tag is formed by a tag antenna structure seriously, and when the antenna structure fluctuates, the performance of the tag also fluctuates correspondingly.
