Referring to fig. 1 to 5, the present embodiment provides a marine drilling riser 15 soft suspension simulation test apparatus, including: the simulation platform 11 is provided with a first through hole extending along the vertical direction; the extension pipe 13 is arranged in the first through hole in a penetrating mode; and the telescopic pipe 13 can be axially telescopic; a riser 15 connected to a lower end of the extension pipe 13; a tension control mechanism 17 including a force application member 19 and a deformable tension member 21; the force application member 19 is connected with the extension pipe 13 and the riser 15 through the tension member 21 so as to apply top tension to the riser 15; a test sensor 23 located on the riser 15; a calculation control module 22, wherein the calculation control module 22 is configured to collect the detection data of the test sensor 23, so as to control the tension control mechanism 17 according to the data, thereby adjusting the top tension.
During the test, the simulation platform 11 is installed on a vessel 65 filled with fluid at a certain depth to simulate the deep sea; and the riser 15 is inserted into the deep sea of the vessel 65 so that the water flow in the vessel 65 will have an impact on the riser 15. Or the simulation platform 11 is installed or erected on a drilling vessel and the riser 15 is extended into the ocean current to have an impact on the riser 15 by the ocean current in the ocean. Since the force application member 19 of the tension control mechanism 17 is connected to the telescopic tube 13 and the riser 15 by the tension member 21, it is possible to apply a top tension to the riser 15; therefore, when the riser 15 is subjected to the impact force of water flow or sea current, the tension member 21 can buffer the impact force applied to the riser 15; thereby reducing the bending degree of the riser 15; thereby conforming to the practical working condition. Further, the displacement and the received stress of the riser 15 in the water flow or the ocean current can be measured by the test sensor 23, and the calculation control module 22 can control the tension control mechanism 17 according to the detection data of the test sensor 23, so as to adjust the top tension; thus yielding the most reasonable top tension. Therefore, the marine drilling riser 15 soft suspension simulation test device according to the embodiment of the present application is more accurate in the top tension applied to the riser 15. Further, since the riser 15 is connected to the lower end of the telescopic tube 13; the telescopic pipe 13 can be axially stretched and contracted; the telescopic tube 13 is able to extend to a certain extent under the action of axial tension, thereby enabling compensation of the axial relative displacement between the vessel and the riser 15.
According to the scheme, the marine drilling riser 15 soft suspension simulation test device disclosed by the embodiment of the application enables the tension piece 21 to buffer the impact force applied to the riser 15 by arranging the simulation platform 11, the extension pipe 13, the riser 15, the tension control mechanism 17, the test sensor 23 and the calculation control module 22; thereby reducing the bending degree of the riser 15; thereby conforming to the practical working condition. The displacement and the stress of the marine riser 15 in water flow or ocean current are measured by the test sensor 23, and the calculation control module 22 controls the tension control mechanism 17 according to the detection data of the test sensor 23, so as to adjust the top tension; thus yielding the most reasonable top tension.
As shown in fig. 1, in the present embodiment, the simulation platform 11 is used to be mounted on a vessel 65 filled with a liquid at a certain depth to simulate the deep sea. For example, as shown in fig. 1, the liquid in the vessel 65 has a level 67. Or the simulation platform 11 is used to be installed or erected on a drilling vessel to have a percussive effect on the riser 15 by the currents in the sea. Further, the simulation platform 11 is provided with a first through hole extending in the vertical direction. The simulation platform 11 extends in the left-right direction, as shown in fig. 1, for example. The simulation platform 11 extending in the left-right direction is provided with a first through hole extending in the up-down direction.
In the present embodiment, the bellows 13 is inserted into the first through hole. And the telescopic tube 13 can be axially telescopic. For example, as shown in fig. 1, the bellows 13 extends in the up-down direction. The extension tube 13 can be extended and contracted in the vertical direction. Further, the extension tube 13 has a first through passage therein extending therethrough in the extending direction thereof. The first through passage is used for the drilling fluid to pass through.
In one embodiment, as shown in FIG. 2, the telescoping tube 13 includes an outer cylinder 25 and an inner cylinder 27 disposed through the outer cylinder 25. Namely, the outer cylinder 25 and the inner cylinder 27 are in a sleeved structure. The inner cylinder 27 is inserted into the first through hole, and the outer cylinder 25 is axially movable relative to the inner cylinder 27 by the tension control mechanism 17. Specifically, the inner cylinder 27 is not axially movable with respect to the simulation platform 11, but the outer cylinder 25 is axially movable with respect to the simulation platform 11, and further the outer cylinder 25 is axially movable with respect to the inner cylinder 27, so that the telescopic tube 13 can be extended and contracted in the axial direction thereof. For example, as shown in fig. 2, the outer cylinder 25 can move in the up-down direction with respect to the simulation platform 11, so that the outer cylinder 25 can move in the up-down direction with respect to the inner cylinder 27, thereby allowing the extension tube 13 to extend and contract in the up-down direction.
In this embodiment, the riser 15 is connected to the telescopic tube 13. In particular, the riser 15 is connected to the outer cylinder 25 so that when there is a relative displacement in the axial direction between the vessel and the riser 15, the outer cylinder 25 can be moved relative to the inner cylinder 27 to compensate for the relative displacement, thereby simulating the operation of the riser 15 under the impact of water or sea currents.
In the present embodiment, the tension control mechanism 17 includes an urging member 19 and a deformable tension member 21. The forcing member 19 is connected to the telescope pipe 13 and the riser 15 by means of a tensioning member 21 to enable top tension to be applied to the riser 15. Specifically, the tension member 21 is a tension ring fixedly sleeved on the outer cylinder 25. The fixing method may be screw fixing, bolt fixing, welding fixing, etc., and this application is not limited thereto. The tension ring can be fixedly sleeved on the outer wall of the outer cylinder 25. Of course, the tension ring may be fixedly sleeved on the inner wall of the outer cylinder 25. So that the tension ring can be coupled with the outer cylinder 25; i.e. the tension ring is connected to the riser 15. The force application member 19 is a hydraulic rod connected to the tension ring. So that the hydraulic rod is connected to the riser 15 through a tension ring; the hydraulic rod can then apply hydraulic pressure to the tension ring which can transfer the hydraulic pressure to the riser 15, thereby applying top tension to the riser 15.
Further, the tension ring can be deformed. In particular, the tension ring can be deformed, for example, radially or axially. Further, the tension ring may be a ring made of iron having a gap. Or the tension ring is a complete ring made of rubber.
Further, the upper end of the outer cylinder 25 is connected to the urging member 19 through a tension ring. The lower end of the outer cylinder 25 is connected to the riser 15. So that on the one hand the outer cylinder 25 can be connected to the force application element 19 via a tension ring; on the other hand the riser 15 can be connected to the forcing member 19 by means of a tension ring. Thus, when the riser 15 is subjected to the impact force of water flow or ocean current, and the riser 15 swings under the impact force, the tension member 21 can buffer the swing, and the bending degree of the riser 15 is reduced.
Further, the tension ring is arranged in the outer cylinder 25 in a penetrating way; the inner cylinder 27 is inserted into the tension ring. The force application member 19 is connected to the tension ring. For example, as shown in fig. 2, the lower end of the force applying member 19 is connected to the tension ring. The connection mode can be screw connection, bolt connection, welding, integral forming and the like. So that on the one hand the outer cylinder 25 can be moved in the up-down direction relative to the inner cylinder 27 by the force application member 19; on the other hand, the force application element 19 can apply a force to the outer tube 25 via the tension ring. The outer cylinder 25 can then transmit this force to the riser 15 to apply a top tension to the riser 15. And for example, as shown in fig. 1, when the riser 15 swings in the left-right direction under the impact force of the water flow or the ocean current, the riser 15 will drive the outer cylinder 25 to swing in the left-right direction; when the outer cylinder 25 swings in the left-right direction, the upper end thereof is restricted by the tension ring, and further, the swing in the left-right direction is restricted. And the riser 15 is restricted in its swing in the left-right direction.
Further, the riser 15 has a second through passage therein extending therethrough in the direction of extension thereof. The second through passage is for the passage of drilling fluid. And the second through passage communicates with the lower end of the first through passage. So that drilling fluid in the first through passage can flow into the second through passage.
Preferably, an annular space is formed between the outer cylinder 25 and the inner cylinder 27. And a sealing filler is arranged in the annular space. The sealing filler is used for sealing the annular space; thereby avoiding leakage of drilling fluid from the riser 15 through the annular space.
In one embodiment, the simulation platform 11 is further provided with a clamping mechanism for clamping the inner cylinder 27.
Specifically, a chuck module 31 and a gimbal module 32 are further disposed on the simulation platform 11. The gimbal module 32 is located between the chuck module 31 and the simulation platform 11. For example, as shown in FIG. 1, chuck module 31 is positioned above simulation platform 11. The gimbal module 32 is located below the chuck module 31 and above the simulation platform 11. The chuck module 31 is used to hold the inner cylinder 27. The inner cylinder 27 can thus be inserted into the first through-hole in the dummy platform 11 by being clamped by the chuck module 31. The gimbal module 32 is used to support the chuck module 31 and can adjust the tilt angle of the chuck module 31 in various directions. Therefore, when the marine riser 15 is impacted by water flow or ocean current, the inclination angle of the inner cylinder 27 of the telescopic pipe 13 can be adjusted through the universal joint module 32, and the actual working condition can be simulated.
Further, as shown in fig. 4 and 5, the chuck module 31 includes: a base 69, a plurality of gripping teeth 71 and a plurality of hydraulic units 73. The base 69 is provided with a fourth through hole. The plurality of gripping teeth 71 are circumferentially distributed around the fourth through hole. The plurality of hydraulic units 73 are provided on the base 69. And a plurality of hydraulic units 73 correspond to the plurality of gripping teeth 71. This correspondence may be such that the number of hydraulic units 73 is equal to the number of gripping teeth 71. One end of each hydraulic unit 73 is connected with the corresponding clamping tooth 71; the other end of each hydraulic unit 73 is connected to the base 69. The hydraulic unit 73 can stretch and contract along the radial direction of the fourth through hole to drive the clamping teeth 71 to move along the radial direction; and then the inner pipe penetrating in the first through hole is clamped and released.
Further, the gimbal module 32 includes: a base 37, a support plate 41, and a plurality of adjustment mechanisms. The base 37 has a second through hole extending in the vertical direction. The support plate 41 has a third through hole extending in the vertical direction. The second through hole and the third through hole are used for the inner tube of the telescopic tube 13 to penetrate through. The chuck module 31 is fixed to the support plate 41. A plurality of adjustment mechanisms are located between the support plate 41 and the base 37, the adjustment mechanisms being circumferentially distributed about the axis of the third through-going hole. Since the chuck module 31 holds the inner pipe, when the riser 15 is subjected to the impact of water flow or sea current, the riser 15 may tilt, and the adjusting mechanism is used to support the weight of the chuck module 31 and the riser 15 on the one hand, and to match the tilting degree of the riser 15 on the other hand.
Further, as shown in fig. 4, the adjusting mechanism includes: cylinder 43, piston 52, connecting rod 53 and spring 54. The cylinder 43 is fixed to the base 37. The piston 52 is inserted into the cylinder 43. The upper end of the connecting rod 53 is connected to the support plate 41, and the lower end of the connecting rod 53 extends into the cylinder 43 and is connected to the upper end of the piston 52. The spring 54 is sleeved outside the connecting rod 53. The upper end of the spring 54 abuts against the support plate 41, and the lower end of the spring 54 abuts against the upper surface of the cylinder 43. In this manner, the spring 54 can adjust the inclination degree of the support plate 41.
In this embodiment, the test sensor 23 is located on the riser 15. Specifically, the riser 15 is externally fixedly sleeved with a plurality of fixing rings 33 having different heights. A test sensor 23 is provided on each of the fixing rings 33. The test sensors 23 include a stress sensor 34 and a position sensor 35. The stress and displacement of the riser 15 when subjected to the impact of a current or sea current can thus be detected by the test sensors 23.
Further, as shown in fig. 3, the fixing ring 33 is a ring having a notch. The opposite inner walls of the notch are provided with a first locking portion 55 and a second locking portion 61. Through holes are formed in the first locking portion 55 and the second locking portion 61, and bolts are inserted into the through holes. So that the fixing ring 33 can be fixed on the outer wall of the riser 15 by means of bolts.
Further, the stress sensor 34 and the position sensor 35 may be located on opposite sides of the fixing ring 33. The stress sensor 34 and the position sensor 35 may be fixedly attached to the fixing ring 33 by screws or the like. The position sensor 35 is used to measure the offset of the riser 15 in three directions, i.e., the X direction, the Y direction, and the Z direction in space.
In one embodiment, a slide rail 36 is mounted on the simulation platform 11. For example, as shown in fig. 1, the slide rail 36 extends in the left-right direction. The tension control mechanism 17 and the gimbal module 32 are both mounted on a slide rail 36. The tension control mechanism 17 and the gimbal module 32 are both able to slide horizontally on the slide rails 36. And the tension control mechanism 17 is enclosed outside the gimbal module 32. So that when the riser 15 is subjected to the impact of water flow or sea current, the riser 15 applies an acting force in the horizontal direction to the telescopic pipe 13; when the extension pipe 13 transmits the acting force to the tension control mechanism 17 and the universal joint module 32, both the tension control mechanism 17 and the universal joint module 32 can move along the slide rail 36, so as to limit the riser 15 to move greatly along the horizontal direction.
In this embodiment, the calculation control module 22 is connected to the tension control mechanism 17 and the test sensor 23. Specifically, the calculation control module 22 may be connected to the tension control mechanism 17 and the test sensor 23 by wires. Or the calculation control module 22 may be connected to the tension control mechanism 17 and the test sensor 23 by wireless transmission. The calculation control module 22 is configured to control the tension control mechanism 17 according to the detection data of the test sensor 23, so as to adjust the top tension. Further, the calculation control module 22 may be a computer or a mobile phone.
In one embodiment, the marine drilling riser 15 soft suspension simulation test device of the embodiment of the present application further includes: a servo control system 63. The calculation control module 22, the universal joint module 32 and the tension control mechanism 17 are all electrically connected with a servo control system 63, and the calculation control module 22 is used for collecting detection data of the stress sensor 34 and the position sensor 35; the servo control system 63 is used for analyzing the detection data so as to control the universal joint module 32 and the tension control mechanism 17; thereby adjusting the tilt angle and top tension. Therefore, the servo control system 63 can control the gimbal module 32 and the tension control mechanism 17 according to the detection data of the stress sensor 34 and the position sensor 35, so that the inclination angle and the top tension of the marine riser 15 under the impact force of water flow or ocean current can be in a better state, and the accurate inclination angle and the accurate top tension can be obtained.
