Description

Technical Field

[0001] This utility model relates to the field of oil drilling and production equipment testing technology, specifically a multi-functional composite oil drilling and production equipment testing platform. Background Technology

[0002] Testing of oil drilling and production equipment is a crucial step in ensuring the safety, efficiency, and environmental friendliness of oil and gas exploration and development. It plays a vital role by simulating extreme downhole environments to rigorously verify the functional integrity, structural strength, sealing performance, material durability, and long-term reliability of the equipment. This allows for the early identification and elimination of design flaws, manufacturing defects, and potential failure points, significantly reducing the risk of catastrophic accidents such as equipment failure, well control failure, production interruption, or environmental pollution during demanding actual operations.

[0003] Authorization announcement number CN212508255U1 discloses a multifunctional composite oil drilling and production equipment test bench, including a test bench main unit, an adjustable support device below the test bench main unit, a wellhead device above the adjustable support device, a movable slide rail mechanism above the test bench main unit, an adjusting motor on the movable slide rail mechanism, a test connection tool below the movable slide rail mechanism, a screw on the test connection tool, a screw sleeve outside the screw, a rotating sleeve outside the screw sleeve, a positioning block on the upper part of the rotating sleeve, and a positioning hole below the screw sleeve. The screw is connected to the adjusting motor. By replacing different sizes of screw sleeves and rotating sleeves, various types of wellhead devices can be tested, and all installation actions of the wellhead can be realized. The performance is stable and reliable. However, this device uses a screw rotation to drive the test connection tool to rise and fall, generating tension and downward force on the wellhead device. It does not mention how to determine and detect the values ​​of tension and downward force, resulting in poor accuracy of test results. It is also incompatible with conventional pressure tests. Therefore, we propose a multi-functional composite oil drilling and production equipment test bench. Utility Model Content

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.

[0015] Please see Figure 1-2 This embodiment provides a technical solution: a multi-functional composite oil drilling and production equipment test bench, including a frame 1 and a test mechanism 3; Frame 1: Heat insulation plates 5 are fixedly connected to the inner walls on both sides of the frame 1. Heating wires 6 are evenly distributed inside the heat insulation plates 5. Motors 7 are symmetrically distributed on both sides of the frame 1. Fan blades 8 are fixedly sleeved on the upper end of the output shaft of each motor 7. The input end of the motor 7 is electrically connected to the output end of the controller 2. After the cabinet door of the frame 1 is closed, the controller 2 controls the heating wires 6 to be powered on (the high temperature test is generally 70 degrees Celsius, so the heating wires 6 can be set as needed. The heat insulation plate 5 can be FR-4 type glass fiber reinforced epoxy resin board, which can withstand high temperature of 140 degrees Celsius and is inexpensive). The internal part of the frame 1 is heated. The output shaft of the motor 7 drives the fan blades 8 to rotate. The rotation of the fan blades 8 drives the air circulation inside the frame 1, making the internal temperature distribution of the frame 1 more uniform. Test mechanism 3 includes a base 31, a fixing plate 32, a pressure sensor 33, a water inlet pipe 37, a connecting pipe 38, and a water outlet pipe 39. The base 31 is fixedly connected to the upper surface of the workbench of the frame 1. The fixing plate 32 is located inside the upper part of the frame 1. Pressure sensors 33 are symmetrically distributed front and back on both sides of the fixing plate 32.

The testing mechanism 3 also includes a mounting plate 34, a sliding column 35, and a hydraulic cylinder 36. The hydraulic cylinder 36 is fixedly connected to the left and right sides of the upper surface of the frame 1, respectively.

The upper surface of the fixed plate 32 is fixedly connected with evenly distributed sliding columns 35. The upper ends of the sliding columns 35 are slidably connected to the inside of adjacent through holes on the top wall of the frame 1. The oil inlets of the oil cylinders 36 are all connected to the external oil pump. The external oil pump is controlled by the controller 2. When the extension end of the oil cylinder 36 extends, the fixed plate 32 moves down, and the sliding columns 35 move down synchronously, making the descent of the fixed plate 32 more stable. The tester manually adjusts the position of the components of the wellhead device so that the bolt holes of the flanges of the components of the wellhead device are aligned with the bolt holes of the connecting flanges of the upper and lower molds 4, and inserts the bolts. Then, the bracket 91 and the plate 93 are removed as a whole. Then, the nut is screwed on the lower end of the stud, so that the components of the wellhead device and the upper and lower molds 4 are integrated into a whole. The extension and retraction end of the hydraulic cylinder 36 extends or retracts, so that the components of the wellhead device are subjected to pressure or tension to simulate various installation actions of the wellhead. The pressure sensor 33 feeds back the changes in pressure or tension to the controller 2 in real time (the force-bearing end of the pressure sensor 33 is connected to the mounting plate 34), which facilitates precise control of the test pressure or tension, and subsequent non-destructive testing of the wellhead, making the test structure more accurate. Temperature sensors 10 are uniformly distributed and fixedly connected to the upper surface of the workbench of the frame 1 and the lower surface of the fixing plate 32. The temperature sensors 10 are bidirectionally electrically connected to the controller 2. The temperature sensors 10 detect the temperature at corresponding points and feed it back to the controller 2. The average temperature recorded by the temperature sensors 10 is the temperature inside the frame 1, which facilitates the control of the temperature inside the frame 1.

[0016] The system also includes a controller 2, which is located on the right side of the frame 1. The input of the controller 2 is electrically connected to an external power source, and the input of the heating wire 6 is electrically connected to the output of the controller 2.

The upper end of the bracket 91 is connected to the plate 93 by bolts. The middle of the plate 93 is provided with a semi-circular groove. The upper surface of the plate 93 coincides with the upper surface of the mold 4 at the lower end. The support mechanism 9 also includes pins 92. The lower end of the bracket 91 and the edge of the fixed plate 32 are provided with evenly distributed positioning holes. Pins 92 are inserted between two vertically adjacent positioning holes. The mold 4 is installed on the upper surface of the base 31 and the lower surface of the fixed plate 32 respectively (the mold 4 is replaced according to the components being tested). The whole assembly consisting of the bracket 91 and the plate 93 is placed on the front and rear sides of the upper surface of the fixed plate 32 (the diameter of the circle formed by the semi-circular groove of the plate 93 is 1-3mm larger than the diameter of the connecting flange of the mold 4 at the lower end, and the plate 93 can be replaced according to the mold 4) and fixed by the pins 92.

[0018] The working principle of the multifunctional composite oil drilling and production equipment test bench provided by this utility model is as follows: In front of the components of the test wellhead device, the mold 4 is installed on the upper surface of the base 31 and the lower surface of the fixing plate 32 respectively (the mold 4 is replaced according to the components being tested). The whole assembly consisting of the bracket 91 and the plate 93 is placed on the front and rear sides of the upper surface of the fixing plate 32 respectively (the diameter of the circle formed by the semi-circular groove of the plate 93 is 1-3mm larger than the diameter of the connecting flange of the mold 4 at the lower end, and the plate 93 can be replaced according to the mold 4), and fixed by the pin 92. The external oil pump is controlled by controller 2, the telescopic end of the oil cylinder 36 extends, the fixed plate 32 moves down, and the sliding column 35 moves down synchronously, making the descent of the fixed plate 32 more stable. The tester manually adjusts the position of the components of the wellhead device so that the bolt holes of the flanges of the components of the wellhead device are aligned with the bolt holes of the connecting flanges of the upper and lower molds 4. After inserting the stud, the whole assembly consisting of the bracket 91 and the plate 93 is taken out. Then, the nut is screwed on the lower end of the stud so that the components of the wellhead device and the upper and lower molds 4 are integrated into a whole. The extension or retraction of the cylinder 36 causes the components of the wellhead device to be subjected to pressure or tension, simulating various installation actions at the wellhead. The pressure sensor 33 feeds back the changes in pressure or tension to the controller 2 in real time (the force-bearing end of the pressure sensor 33 is connected to the mounting plate 34), which facilitates precise control of the test pressure or tension, and subsequent non-destructive testing of the wellhead, making the test structure more accurate. The flange at the rear end of the connecting pipe 38 can be bolted to the flange at the front end of the outlet pipe 39, and water can be supplied to the inlet pipe 37 by an external water pump to conduct pressure tests on the components of the wellhead device. After closing the cabinet door of rack 1, the heating wire 6 is powered on by the controller 2 (the high temperature test is generally 70 degrees Celsius, so the heating wire 6 can be set as needed; the heat insulation board 5 can be FR-4 type glass fiber reinforced epoxy resin board, which can withstand high temperature of 140 degrees Celsius and is inexpensive), to heat the inside of rack 1. The output shaft of motor 7 drives the fan blade 8 to rotate, and the rotation of fan blade 8 drives the air circulation inside rack 1, making the temperature distribution inside rack 1 more uniform. Temperature sensor 10 detects the temperature at corresponding locations and feeds it back to controller 2. The average temperature recorded by temperature sensor 10 is the temperature inside rack 1, which facilitates the control of the temperature inside rack 1.
