[0001] The invention relates to the field of hydraulic control pipeline pressure testing, and in particular to a well control hydraulic control pipeline pressure testing detection device and a detection method thereof. Background Art

[0002] The existing well control hydraulic control pipeline pressure test is that the operator controls the crane to hoist the pressure test hydraulic control pipeline into the pressure test pit. The operator can only connect one hydraulic control pipeline at a time for installation work. There is no dedicated mature mold for testing, and the labor intensity is very high, the pressure test efficiency is low, and the hydraulic pipeline cannot be fixed during the pressure test, which poses certain safety risks. The length of the hydraulic control pipeline can only be measured manually with a steel tape measure, which has a large error. Summary of the invention

[0003] The present invention provides a well control hydraulic control pipeline pressure test detection device and a detection method thereof, which solves the problems of detection efficiency, detection accuracy and test safety, realizes simultaneous detection of multiple hydraulic control pipelines, and improves detection accuracy and detection efficiency.

[0004] The technical problem solved by the present invention can be achieved by adopting the following technical solutions: A well control hydraulic control pipeline pressure test detection device and detection method thereof, comprising: Bracket; A bearing groove, which is detachably connected to the upper surface of the bracket; A connecting seat, the connecting seat is slidably connected to the bracket; An oil connection valve, which is detachably connected to the connection seat; A card seat, which is detachably connected to the bracket, and the oil connection valve and the card seat are arranged relatively; A fuel tank, which is detachably connected to the bracket; The high-pressure distribution valve group is connected to the oil tank, and the oil outlet end of the high-pressure distribution valve group is connected to the card seat. Preferably, a laser ranging module is detachably connected to the connecting seat, and a ranging baffle is detachably connected to the other end of the bracket, and the active surface of the ranging baffle and the thread root of the socket are located on the same plane.

[0005] Preferably, the bracket is detachably connected with slide rails located on both sides of the bearing slot, and the connecting seat is slidably connected to the slide rails.

[0006] Preferably, at least one pair of bearing grooves are detachably connected to the bracket, at least one pair of the bearing grooves has a slidable connecting seat above each, at least one pair of the ends of the bearing grooves and located on the bracket are detachably connected to an oil connection valve, and the high-pressure distribution valve group is respectively connected to the oil connection valve.

[0007] Preferably, a limiting cover is hinged on the bearing slot, and a buckle 1 is detachably connected to a side surface of the bearing slot, and the buckle 1 is snap-connected to the limiting cover.

[0008] Preferably, pulley blocks are detachably connected in equal intervals in the bearing groove.

[0009] Preferably, a card slot is provided in the card base, a card plate is provided on the card base, and a second buckle is provided between the card plate and the card base for detachable connection.

[0010] Preferably, a wiring harness protective shell is riveted in the bearing groove.

[0011] A method for testing pressure of a well control hydraulic pipeline includes at least the well control hydraulic pipeline testing pressure testing device and the testing method described above, and is characterized in that it also includes the following steps: Several hydraulic control pipelines are hoisted into the pressure test pit, and one end of the multiple pipelines is connected to the oil control connecting valve first, and then each hydraulic control pipeline is connected to the oil control connecting valve respectively, and then the oil control connecting valves are placed in the bearing tank respectively, and the other end of the hydraulic control pipeline is clamped with the clamping seat, and then the connecting seat is pulled to make the hydraulic control pipeline initially straightened. At the same time, the initial value is preliminarily determined by the laser ranging module, and then the limit cover is flipped onto the bearing tank and clamped with a buckle, and then the oil in the oil tank is pumped into the hydraulic control pipeline through the high-pressure distribution valve group. Since the hydraulic control pipeline will be straightened after being pressurized, the pressure will be stabilized for a period of time. At this time, the laser ranging module measures the post-measurement value of the hydraulic control pipeline and whether the pressure change is stable, so as to judge whether this hydraulic control pipeline is qualified.

[0012] The beneficial effect of the present invention is that: due to the use of a high-pressure distribution valve group, the problem of low efficiency of single-line testing is effectively solved, thereby achieving multiple-line testing through distribution oil circuits, and at the same time, each hydraulic control pipeline will not be affected by each other.

[0013] The use of a laser ranging module effectively solves the distance measurement problem of the hydraulic control pipeline, thereby achieving accurate readings after the hydraulic control pipeline is stabilized and slightly deformed.

[0014] The use of the slide rail effectively solves the problem that the hydraulic control pipeline will produce micro-deformation after pressurization, which will drive the connecting seat to move on the slide rail and drive the laser ranging module to measure the distance.

[0015] The use of a pulley block effectively solves the problem of poor sliding effect of the oil pipe after the hydraulic control pipeline is placed in the load-bearing groove at the end with the oil connection valve, thereby enabling the hydraulic control oil pipe to slide in the load-bearing groove and quickly reach the end of the load-bearing groove with the connecting seat.

[0022] In actual use: assemble and debug the detection device in the pressure test pit, then hoist the hydraulic control pipeline into the pressure test pit, insert the self-sealing end of the hydraulic control pipeline into the bearing tank 2 before it is completely lowered, and then continue to lower the hydraulic control pipeline. The hydraulic control pipeline moves in the bearing tank 2 toward the clamping seat 5, and then first connect the oil connection valve 4 with the other end of the hydraulic control pipeline, and then slide the clamping seat 5 through the connecting seat 3 to make the clamping seat 5 and the hydraulic control pipeline clamped. At this time, the hydraulic control pipeline is placed flat in the bearing tank 2 and connected. After completion, personnel stay away from the hydraulic control pipeline and perform pressure test at the same time. The oil in the oil tank 6 is pumped into the hydraulic control pipeline through the high-pressure distribution valve group 7 for pressure test. The test is carried out by maintaining a certain pressure for a certain period of time, and then the hydraulic control pipeline with pressure is manually measured to obtain the data at this time. The obtained length data of the pressure holding thickness is compared with the original data and the fluctuation amplitude of the pressure holding is analyzed, and the hydraulic control pipeline is judged to be qualified according to the data and data range specified in the industry specifications.

[0023] In this embodiment, the high-pressure distribution valve group 7 is equipped with accessories such as a pressure sensor, a high-pressure stop valve and a solenoid valve, which can realize individual oil supply or collective oil supply, as well as oil pressure data detection.

[0025] In actual use: after the hydraulic control pipeline is pressurized, the laser ranging module 8 cooperates with the ranging baffle 9 to obtain the length of the hydraulic control pipeline at this time, and monitor the value change at this time in real time. By testing for a period of time and taking the highest value, it can be determined whether the deformation length of the hydraulic control pipeline meets the requirements.

[0027] In actual use: the connecting seat 3 slides on the slide rail 10 under the influence of the hydraulic control pipeline, which facilitates the laser ranging module 8 to monitor data.

[0028] In this embodiment, the slide rail 10 may be provided with scale lines to facilitate direct observation with the naked eye.

[0029] Embodiment 4: Reference Figure 1The difference of this embodiment is that: at least one pair of bearing grooves 2 are detachably connected to the bracket 1, at least one pair of the bearing grooves 2 are respectively provided with a slidable connecting seat 3 above, at least one pair of ends of the bearing grooves 2 and located on the bracket 1 are detachably connected with an oil connection valve 4, and the high-pressure distribution valve group 7 is respectively connected to the oil connection valve 4.

[0032] In actual use: after the hydraulic control pipeline is placed flatly in the bearing groove 2, the limit cover 11 is buckled on the bearing groove 2 and locked with the side of the bearing groove 2 through the buckle 12, so as to prevent the hydraulic control pipeline from being ejected from the bearing groove 2 due to damage or unstable connection within the rated pressure. Multiple limit covers 11 can be set.

[0033] Embodiment 6: Reference Figure 1 The difference of this embodiment is that: the bearing groove 2 is equidistantly and detachably connected with a pulley block 13 .

[0034] In actual use: the pulley block 13 can facilitate the hydraulic control pipeline to slide in the bearing tank 2, making it easy to place, while reducing the friction with the bearing tank 2, thereby reducing the impact on the monitoring of the numerical value.

[0035] Embodiment 7: Reference Figure 1 and Figure 3 The difference of this embodiment is that: a card slot is provided in the card holder 5, a card plate 14 is provided on the card holder 5, and a buckle 15 is detachably connected between the card plate 14 and the card holder 5.

Embodiment 9: Reference Figure 1-3 A method for testing pressure of a well control hydraulic pipeline includes at least the well control hydraulic pipeline testing pressure testing device and the testing method described above, and also includes the following steps: The first step is to hoist several hydraulic control pipelines into the pressure test pit, and connect one end of the multiple pipelines with the oil control connecting valve 4 first, and then connect each hydraulic control pipeline with the oil control connecting valve 4 respectively, and then put the oil control connecting valve 4 into the bearing tank 2 respectively, and connect the other end of the hydraulic control pipeline with the clamping seat 5, and then pull the connecting seat 3 to make the hydraulic control pipeline initially straighten, and at the same time, preliminarily determine the initial value through the laser ranging module 8, and then flip the limit cover 11 onto the bearing tank 2, and clamp it with the buckle 12, and then pump the oil in the oil tank 6 into the hydraulic control pipeline through the high-pressure distribution valve group 7. Since the hydraulic control pipeline will be straightened after being pressurized, the pressure will be stabilized for a period of time. At this time, the laser ranging module 8 measures the measured value of the hydraulic control pipeline and whether the pressure change is stable, so as to judge whether this hydraulic control pipeline is qualified.

[0039] In actual use: the hydraulic control pipeline has different lengths, and the test data is different, and the pressure test or sealing performance test is performed; For example, a hydraulic control pipeline has the following specifications: 25mm*35MPa*10m, a length of 10m before detection, a detection pressure of 36.60MPa, a pressure stabilization of 10min, a pressure drop of 0.6MPa, a length of 10.02m after detection, and a length difference of 0.02m, thus confirming that the hydraulic control pipeline is well sealed, has no leakage, and has no deformation.
