Description

Technical Field

[0001] This utility model relates to the field of parameter measuring device technology, and in particular to a multi-parameter measuring instrument for borehole drilling. Background Technology

[0002] The oil, gas, and water mixture produced at the wellhead is transported via the oil pipeline to a two-phase metering separator. The separated gas is measured by a flow meter, while the liquid (oil and water) is measured by an instrument or a glass tube, tipping bucket, or dual-volume separator. Water content is sampled and tested, or measured by an online water content analyzer. After the gas and liquid are combined, the mixture is transported to a transfer station or a centralized oil and gas processing station. The multi-parameter single-well metering instrument is a comprehensive monitoring instrument used on crude oil outlet pipelines to measure static pressure, differential pressure, temperature, flow rate, and crude oil water content.

[0003] With the advancement of the Internet of Things era, various measurement needs in existing crude oil export pipelines have evolved. Previously, pressure, differential pressure, flow rate, and temperature at the crude oil outlet were measured separately, and water content required separation using specialized instruments. This resulted in a large number of pipeline inspection instruments, occupying significant installation space and hindering management. To address these issues, application number 201920077547.X discloses a multi-parameter single-well metering device. This device includes a cylinder with flanges threaded to both ends. A vertical pole assembly is mounted on the top of the cylinder, and an explosion-proof housing is fixed to the top of the assembly using hexagonal screws. An electrical module is installed inside the explosion-proof housing, connected to a sensor module and a temperature sensor. The sensor module and temperature sensor are respectively mounted on the upper end of the vertical pole assembly and on the cylinder. A nozzle is installed inside the cylinder. A cable outlet and a wireless connector are mounted on the explosion-proof housing, with an antenna mounted on the wireless connector.

[0004] The above-mentioned patent has the following problems when used: In actual use, the flange on the multi-parameter meter needs to be fixed on the test pipeline by the staff using multiple fixing bolts. Since the multi-parameter meter needs to be maintained regularly, the disassembly and assembly process of the multi-parameter meter is complicated. Moreover, additional tools are required to operate it, which greatly reduces the convenience of the staff in maintaining the multi-parameter meter. There is room for improvement.

[0005] Therefore, this application proposes a multi-parameter measuring instrument for borehole drilling to solve the above problems.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a multi-parameter measuring instrument for borehole drilling, with reference to... Figures 1-6 A multi-parameter measuring instrument for drilling includes a tube body 1, a multi-parameter measuring instrument body 2, and a fixing mechanism 4.

[0031] The pipe body 1 is equipped with a multi-parameter measuring instrument body 2. Well pipes 3 are inserted into both ends of the pipe body 1. Each well pipe 3 is equipped with a fixing mechanism 4. Both fixing mechanisms 4 are connected to the pipe body 1. A sealing ring 1 is fixedly installed at one end of each well pipe 3. Two sealing rings 2 are fixedly installed inside the pipe body 1 and are in contact with the two sealing rings 1 respectively.

[0032] The fixing mechanism 4 includes a limiting rod 41, a rotating shaft 42, a first slider 43, a first locking block 44, a second slider 45, a second locking block 46, and a rotating plate 47. The same limiting rod 41 is inserted into the well pipe 3 and the pipe body 1. The first locking block 44 is movably connected to one side of the limiting rod 41 and engages with the pipe body 1. The second locking block 46 is movably connected to the other side of the limiting rod 41 and engages with the well pipe 3. Through the cooperative design between the pipe body 1, the well pipe 3, and the fixing mechanism 4, not only can the multi-parameter measuring instrument body 2 be quickly disassembled and assembled, improving convenience, but it can also prevent the limiting rod 41 from developing gaps between the well pipe 3 and the pipe body 1 due to wear and tear after long-term use, thus greatly improving convenience and practicality.

[0033] In this embodiment, the pipe body 1 and the well pipe 3 are respectively provided with a first groove 5 and a second groove 6. Both the first groove 5 and the second groove 6 are adapted to the limiting rod 41, which facilitates the insertion of the limiting rod 41 into the first groove 5 and the second groove 6. Through the interaction between the limiting rod 41 and the first groove 5 and the second groove 6, the pipe body 1 and the well pipe 3 can be limited and fixed (see attached figure). Figure 4 ).

[0034] In this embodiment, the locking block 44 is engaged with the locking slot 5, and a slider 43 is fixedly connected to the locking block 44. The slider 43 is slidably connected to the limiting rod 41. The interaction between the slider 43 and the limiting rod 41 can achieve the effect of the locking block 44 extending outward.

[0035] In this embodiment, the second locking block 46 is engaged with the second locking slot 6, and the second locking block 46 is fixedly connected with the second sliding block 45. The second sliding block 45 is slidably connected with the limiting rod 41. Through the interaction between the second sliding block 45 and the limiting rod 41, the second locking block 46 can achieve the effect of extending outward.

[0036] In this embodiment, a rotating shaft 42 is rotatably connected to the limiting rod 41. One end of the rotating shaft 42 is threadedly connected to the tube body 1. Through the threaded transmission between the rotating shaft 42 and the tube body 1, the limiting rod 41 can be limited and fixed.

[0037] In this embodiment, a bearing is fixedly sleeved on the rotating shaft 42, and the outer wall of the bearing is fixedly connected to the limiting rod 41. A rotating plate 47 is fixedly connected to one end of the rotating shaft 42, which facilitates the operator to rotate the rotating shaft 42.

[0038] In this embodiment, the first locking block 44 and the second locking block 46 are symmetrical to each other. One end of the first locking block 44 and the second locking block 46 is longer than one end of the limiting rod 41, so that the first locking block 44 and the second locking block 46 can abut against the pipe body 1 and the well pipe 3 respectively. One end of the first locking block 44 and the second locking block 46 abut against the pipe body 1 and the well pipe 3 respectively.

[0039] In this embodiment, the multi-parameter meter body includes an explosion-proof housing, an electrical module, a sensor module, a temperature sensor, a cable outlet, a wireless connector, and an antenna. Through the function of the multi-parameter meter body 2, it can monitor drilling parameters in coal mines (able to display real-time values ​​such as flow rate, pressure, temperature, and flow velocity on-site). The top of the pole assembly is fixedly connected to the explosion-proof housing with hexagonal screws. The electrical module is installed inside the explosion-proof housing, and the sensor module and temperature sensor (PT100 model) are connected to the electrical module. The sensor module and temperature sensor are respectively installed on the upper end of the pole assembly and the cylinder. A nozzle is installed inside the cylinder, and a cable outlet is installed on the explosion-proof housing. The wireless connector, with its main function of the outgoing gland, secures and seals the connecting cable. Securement means locking the cable in place to prevent axial displacement and radial rotation, ensuring a proper connection. Sealing refers to IP protection, i.e., dust and water resistance. An antenna is installed on the wireless connector, allowing for wireless signal output (GPRS, ZGIBEE, NB) in addition to RS485, enabling connection to a terminal for monitoring crude oil. The specific structure and working principle of the multi-parameter meter body 2 can be found in the document with application number 201920077547.X, which is prior art and will not be elaborated further.

[0040] Working principle: In use, firstly, insert both ends of the pipe body 1 into the well pipes 3 on both sides, aligning the first slot 5 with the second slot 6. Then, insert the limiting rod 41, the first locking block 44, and the second locking block 46 into the first slot 5 and the second slot 6, aligning the external thread of one end of the rotating shaft 42 with the threaded hole on the pipe body 1. Next, by rotating the rotating plate 47, the rotating shaft 42 rotates on the limiting rod 41 and engages with the pipe body 1 through threaded transmission. This causes the limiting rod 41, the first locking block 44, and the second locking block 46 to continue moving inward, with one end of the first locking block 44 and the second locking block 46 abutting against the pipe body 1 and the well pipe 3, respectively. At this time, through the interaction between the limiting rod 41, the first locking block 44, and the second locking block 46 and the first slot 5 and the second slot 6, the pipe body 1 and the well pipe 3 are fixed and limited, thus achieving rapid assembly. Conversely, rapid disassembly can be achieved.

[0041] When one end of the locking block 44 and the locking block 46 abuts against the pipe body 1 and the well pipe 3 respectively, the interaction between the slider 1 43, the slider 2 45 and the limiting rod 41 causes the locking blocks 44 and 46 to extend outward, and the outer walls of the locking blocks 44 and 46 to abut against the pipe body 1 and the well pipe 3 respectively, and the pipe body 1 and the well pipe 3 to make closer contact. This achieves the effect of preventing the limiting rod 41 from making movement due to wear after long-term use.

[0042] The technological advancements of this invention compared to existing technologies are as follows: through the cooperation of various components, not only can the multi-parameter measuring instrument body 2 be quickly disassembled and assembled, improving convenience, but it can also prevent the limit rod 41 from moving due to wear caused by prolonged use. Moreover, the structure is simple and more practical.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
