Description

Technical Field

[0001] The utility model relates to the technical field of drill rod management, in particular to a wellhead collection device. Background Art

[0002] Currently, accurate management of drill pipe usage and remaining lifespan presents significant challenges in drilling operations. Due to a lack of effective monitoring methods, drill pipe is often scrapped prematurely due to an inability to accurately assess its actual condition, or continues to be used even after reaching the end of its lifespan. This not only increases operating costs but can also negatively impact the safety and efficiency of drilling operations.

[0003] Furthermore, after completing downhole operations, the drill pipes, when returned to the warehouse, require manual cleaning of surface stains and paper records. This traditional method is not only inefficient but also prone to errors, making it difficult to track and manage the status of the drill pipes. More seriously, after a long period of downhole operation, the steel grade information on the surface of the drill pipes becomes difficult to identify due to wear, making it impossible to accurately record the usage information of the drill pipes, which in turn affects the effective management of the drill pipes throughout their life cycle. At the same time, due to the lack of precise understanding of the damage to the drill pipes, it is often difficult to develop a reasonable repair and replacement plan, which can lead to unnecessary losses and waste. Finally, due to the current lack of precise management of each drill pipe, drill pipes from different pipelines may be incorrectly combined during operations, which not only increases the actual number of drill pipes required for drilling but also may lead to safety hazards during operations.

[0004] Therefore, a device for identifying the drill pipe needs to be developed during the process of the drill pipe going up and down the well. Utility Model Content

[0029] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] This embodiment provides a wellhead data collection device, such as Figure 1-Figure 7 As shown, it includes a protective housing 1, a ring bracket 2, and multiple antenna units 3. The ring bracket 2 is ring-shaped, and the shape of the protective housing 1 is adapted to the ring bracket 2 and is a ring structure with upper and lower openings. The ring bracket 2 can be a steel structure with strong support capacity.

[0031] The annular support 2 has multiple mounting windows 23, evenly spaced around its circumference. Each antenna unit 3 is mounted in a corresponding mounting window 23. The shape of the mounting windows 23 matches the shape of the antenna units 3, such as being circular or rectangular. Multiple antenna units 3 can identify drill rods passing through the center of the annular support 2 from multiple angles, achieving higher recognition accuracy. The recognition technology for the antenna units 3 is conventional.

[0032] The protective housing 1 is connected to the outer side of the annular support 2 and is used to protect the multiple antenna units 3 installed on the annular support 2. The protective housing 1 can be a corrosion-resistant steel structure.

[0033] When the wellhead data collection device of this embodiment is used, it is placed around the wellhead of an oil field, so that the drill pipe embedded with the electronic tag passes through the middle of the ring structure during the up and down movement. The antenna unit will identify the drill pipe with the electronic tag, accurately record the time when the drill pipe is lowered into the well and the time when it comes up from the well, and connect the data to the background software, bind it with other relevant information, and display it.

[0034] As a preferred embodiment, the ring bracket 2 is in the shape of a regular polygon. Specifically, the cross section of the ring bracket 2 can be a regular quadrilateral, pentagon, hexagon or other polygonal structure. The shape of the protective shell 1 corresponds to the shape of the ring bracket 2. An antenna unit 3 is installed on each side of the ring bracket 2 through the installation window 23. In this embodiment, the ring bracket 2 is a regular hexagonal structure as an example. Figure 1 and Figure 2 As shown, an antenna unit 3 is installed on each face, for a total of six antenna units 3. The protective housing 1 also has a regular hexagonal structure. The antenna units 3 are flat-plate structures, installed on the six faces of the annular frame. They can identify drill rods passing through the center of the annular support 2 from multiple angles, ensuring accurate identification.

[0035] In a preferred embodiment, the annular bracket 2 includes a first top plate 22 and an inner plate 21. The first top plate 22 is perpendicularly connected to the inner plate 21 and extends outward. The antenna unit 3 is mounted on the inner plate 21 through a mounting window 23. The first top plate 22 and the inner plate 21 can be a one-piece structure, formed by bending the plate. The inward side of the antenna unit 3 can be positioned toward the center of the annular bracket through the mounting window 23, allowing for closer proximity to the drill rod passing through the center of the annular bracket 2, ensuring more accurate identification.

[0036] As a preferred embodiment, the protective housing 1 includes an outer shell 11 and a base 12. The outer shell 11 is connected to the outside of the annular bracket 2 and forms an inner cavity 6 between the outer shell 11 and the annular bracket 2. The antenna unit 3 protrudes into the inner cavity 6, so that the outer shell 11 protects the antenna unit in the inner cavity 6.

[0037] The base 12 is connected to the bottom ends of the outer shell 11 and the annular bracket 2. The base 12 has a U-shaped longitudinal cross-section, with its two sides connected to the inner plate 21 and the outer plate 111, respectively, to enhance the stability of the connection. Specifically, the base 12, outer shell 11, and annular bracket 2 can be connected by bolts.

[0038] As a preferred embodiment, Figure 6 As shown, the outer shell 11 includes a second top plate 112 and an outer plate 111. The second top plate 112 is perpendicularly connected to the outer plate 111 and extends inward. The second top plate 112 and the outer plate 111 can be an integrated structure, providing good support strength. The second top plate 112 is connected to the first top plate 22 of the annular bracket 2, further strengthening the connection strength between the outer shell 11 and the annular bracket 2. The outer plate 111 is arranged on the outside of the annular bracket 2. On each side of the annular bracket 2, the outer plate is arranged parallel to the inner plate 21.

[0039] As a preferred embodiment, Figure 4 As shown, a support edge 24 is provided around the mounting window 23, extending outward from the inner panel 21 and perpendicular to the inner panel 21. When the antenna unit 3 is installed in the mounting window 23, the support edge 24 surrounds the antenna unit 3, limiting its position and providing support, thereby ensuring a more secure installation. In this embodiment, both the mounting window and the antenna unit are rectangular.

[0040] As a preferred embodiment, Figure 6 As shown, the antenna unit 3 has a connecting edge 31 arranged along its periphery. When the antenna unit 3 is installed in the installation window 23, the connecting edge 31 is perpendicular to the supporting edge 24 and is clamped on the outside of the supporting edge 24 to further limit the antenna unit in the installation window.

[0041] As a preferred embodiment, Figure 4 and Figure 7 As shown, a mounting edge 25 is connected to the support edge 24, parallel to the connecting edge 31. The mounting edge 25 extends away from the center of the mounting window 23 and is arranged along the vertical support edge 24. The mounting edge 25, support edge 24, and inner panel 21 form an integrated structure. The connecting edge 31 of the antenna unit 3 is connected to the mounting edge 25 via a connector 5. The connector 5 is attached to the outside of the mounting edge 25 and serves to limit the connection edge 31.

[0042] As a preferred embodiment, Figure 4 As shown, the connecting member 5 includes a first side plate 51 and a second side plate 52. The first side plate 51 and the second side plate 52 are arranged in parallel and are connected by a transition portion 53. Figure 3 As shown, the first side plate 51 is connected to the inner side plate 21 by bolts passing through the mounting edge 25, and the connection is firm.

[0043] The connecting edge 31 of the antenna unit in this embodiment is located between the second side plate 52 of the connector 5 and the mounting edge 25 , so that the antenna unit can be firmly fixed on the annular bracket 2 .

[0044] As a preferred embodiment, the wellhead data collection device of this embodiment further includes multiple lifting rings 4 mounted on the top of the protective housing 1. The bottom ends of the lifting rings 4 extend through the second top plate 112 of the outer shell 11 and connect to the first top plate 22 of the annular bracket 2, ensuring a more secure connection. Specifically, four lifting rings 4 are provided, symmetrically connected to the top of the protective housing 1. The provision of the lifting rings 4 facilitates the lifting of the wellhead data collection device to the wellhead using a lifting device.

[0045] When the wellhead collection device of this embodiment is applied to the management system of drill pipes, an RFID drill pipe electronic tag is installed on each drill pipe. When the drill pipes leave the manufacturer's factory and arrive at the purchaser's warehouse, a handheld reader can be used to read and count them for storage. When each well team needs drill pipes, the handheld reader can be used to manage the outbound delivery. Subsequent operations including on-site management, inventory, repair and maintenance are all managed using the handheld reader in conjunction with the app software, and the data is synchronized with the background system management software.

[0046] The drill rod up and down management utilizes the wellhead acquisition device of this embodiment installed at the wellhead to read the RFID drill rod electronic tag embedded on each drill rod, and record the time of going up and down the well in detail, eliminating the previous chaotic and rough record management mode. The data collected by the wellhead acquisition device is synchronized with the app and the background management software. The drill rod management system is based on the application of RFID technology on drilling tools. It is an application product for effectively managing the entire life cycle of drilling tools. It can track and monitor the performance and detailed usage of individual drilling tools throughout the entire life cycle of drilling tools. During the well operation, the up and down time of a single drill tool can be recorded in real time, and it can also be combined with RFID based on the relevant data provided on site to record the torsional force, position, temperature, etc. of a single drill tool in the downhole environment, reducing repair and maintenance costs and improving operational efficiency to ensure maximum asset utilization and allocation throughout the drilling tool cycle.

[0047] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the scope of protection of the present invention.
