Description

Technical Field

[0001] This utility model relates to the field of oil logging equipment technology, and in particular to a self-priming vertical device for oil logging sensors. Background Technology

[0002] Oil logging sensor installation devices are important equipment for logging and drilling to measure drilling fluid volume. They mainly serve to support and fix the sensors and keep them perpendicular to the drilling fluid surface. During oil logging, the installation position and perpendicularity of the sensors are crucial to the accuracy of the measurement data.

[0003] Traditional sensor installation often relies on manual operation to adjust its verticality. This method is not only inefficient, but also makes it difficult to ensure that the installation can achieve a precise vertical state every time. In complex drilling environments, such as offshore drilling platforms or land drilling areas with unstable terrain, the sensors are prone to displacement due to factors such as vibration and shaking, which in turn affects the reliability of logging data. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: it is difficult to guarantee that the sensor can achieve a precise vertical state every time it is installed. In complex drilling environments, such as offshore drilling platforms or land drilling areas with unstable terrain, the sensor is prone to displacement due to factors such as vibration and shaking, which affects the reliability of logging data. Therefore, this invention proposes a self-priming vertical device for oil logging sensors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A self-priming vertical device for an oil well logging sensor includes a base, a mounting seat fixedly installed at the center of the base, a spherical groove opened at the upper end of the mounting seat, a magnetic ball rolled and embedded in the spherical groove, a mounting plate fixedly installed on the top of the magnetic ball, and a sensor body mounted on the mounting plate by a fixing frame assembly.

[0007] The magnetic sphere contains a permanent magnet, and an adjustable magnetic field strength electromagnetic coil is installed on the base corresponding to the position of the permanent magnet. The magnetic sphere is located at the center of the electromagnetic coil. A verticality detection unit is fixedly installed on the mounting bracket, and a control unit is installed on the mounting plate. The control unit is electrically connected to the verticality detection unit and the electromagnetic coil.

[0008] Preferably, the fixing frame includes a threaded rod vertically fixedly mounted on the mounting plate, a threaded sleeve threaded onto the upper end of the threaded rod, and a connecting plate fixedly mounted on the upper end of the threaded sleeve. The sensor body is fixedly mounted on the connecting plate, and the verticality detection unit is fixedly mounted on the side of the threaded sleeve.

[0009] Preferably, the control unit is a programmable logic controller, and the control unit is equipped with a verticality threshold.

[0010] Preferably, there is a gap between the magnetic sphere and the spherical groove, and the gap is filled with grease.

[0011] Preferably, a protective cover is fixedly installed on the base, and the electromagnetic coil is located inside the protective cover.

[0012] Preferably, connecting ears are fixedly installed on both sides of the base, and shock-absorbing rubber pads are fixedly installed on the lower surface of both connecting ears.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The device is installed on the logging equipment or drilling platform via a base. The current magnitude and direction of the electromagnetic coil are controlled by the control unit and the verticality detection signal to adjust the rotation angle of the magnetic ball, thereby realizing the automatic vertical adjustment of the sensor. This eliminates the need for frequent manual intervention, improves installation efficiency and vertical accuracy, and ensures the accuracy of logging data.

[0015] 2. The closed-loop control of the verticality detection unit and control unit can monitor and adjust the verticality of the sensor in real time, effectively deal with various interference factors in the drilling process, and keep the sensor in a vertical state at all times.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 A self-priming vertical device for an oil well logging sensor includes a base 1, a mounting seat 2 fixedly installed at the center of the base 1, a spherical groove at the upper end of the mounting seat 2, a magnetic ball 3 rolled and embedded in the spherical groove, a mounting plate 4 fixedly installed on the top of the magnetic ball 3, a sensor body 6 mounted on the mounting plate 4 via a fixing bracket 5 assembly, connecting ears 13 fixedly installed on both sides of the base 1, and shock-absorbing rubber pads fixedly installed on the lower surface of both connecting ears 13 to reduce the impact of external vibration on the device. The base 1 has a horizontal mounting plane, providing a stable support foundation for the entire device.

[0022] The magnetic sphere 3 contains a permanent magnet. An adjustable magnetic field strength electromagnetic coil 7 is installed on the base 1 corresponding to the permanent magnet. The electromagnetic coil 7 is made of multiple turns of fine wire to improve its magnetic field control accuracy over the magnetic sphere 3. The magnetic sphere 3 is located at the center of the electromagnetic coil 7. A perpendicularity detection unit 8 is fixedly installed on the mounting bracket 5, and a control unit 9 is installed on the mounting plate 4. The control unit 9 is electrically connected to the perpendicularity detection unit 8 and the electromagnetic coil 7. The control unit 9 uses a programmable logic controller and has a set perpendicularity threshold.

[0023] The verticality detection unit 8 is mounted on the sensor mounting bracket 5 and uses a dual-axis tilt sensor, which can accurately measure the tilt angle of the sensor in two mutually perpendicular directions and transmit the detection signal to the control unit 9.

[0024] The control unit 9 is electrically connected to the verticality detection unit 8 and the electromagnetic coil 7. It adopts a programmable logic controller and has a preset verticality threshold. When the received tilt angle exceeds the threshold, the control unit 9 automatically starts the adjustment program of the electromagnetic coil 7, calculates the required electromagnetic force according to the size and direction of the tilt angle, and controls the current magnitude and direction of the electromagnetic coil 7 to adjust the rotation angle of the magnetic ball 3, thereby realizing the automatic vertical adjustment of the sensor.

[0025] The mounting bracket 5 includes a threaded rod 10 vertically fixed on the mounting plate 4, a threaded sleeve 11 threaded onto the upper end of the threaded rod 10, and a connecting plate 12 fixedly installed on the upper end of the threaded sleeve 11. The sensor body 6 is fixedly installed on the connecting plate 12, and the verticality detection unit 8 is fixedly installed on the side of the threaded sleeve 11. By rotating the threaded sleeve 11, the threaded sleeve 11 can move up and down under the action of the threaded rod 10, thereby adjusting the height of the sensor body 6.

[0026] There is a gap between the magnetic ball 3 and the spherical groove, and the gap is filled with grease to reduce the friction when the magnetic ball 3 rotates.

[0027] A protective cover 14 is fixedly installed on the base 1, and the electromagnetic coil 7 is located inside the protective cover 14 to protect the electromagnetic coil 7 from interference from external dust, moisture and other factors.

[0028] In this invention, the base 1 is first fixed in a suitable position on the logging equipment or drilling platform. The oil logging sensor is then installed on the mounting bracket 5. After the device is started, the verticality detection unit 8 monitors the verticality of the sensor in real time and transmits the detection signal to the control unit 9. When the verticality of the sensor exceeds a preset threshold, the control unit 9 controls the electromagnetic coil 7 to generate a corresponding magnetic field change, causing the magnetic ball 3 to rotate and adjust the mounting plate 4 and the sensor to a vertical state. Throughout the drilling process, the device continuously monitors and adjusts the verticality to ensure that the sensor always maintains a precise vertical position, providing reliable data support for oil logging.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
