Description

Technical Field

[0001] The invention belongs to the field of technology and equipment for pressure-operated operations, and in particular relates to a pressure-operated operation pipe string wellhead data acquisition device. Background Art

[0002] Pressure-operated operation is an advanced downhole operation technology that can be used to carry out well repair operations without killing the well. Compared with the traditional conventional well killing technology, the pressure-operated operation technology solves the problem of contaminating the downhole production layer caused by the use of killing fluid in traditional well killing operations. Moreover, since the pressure-operated operation can be carried out directly without reducing the pressure in advance, it saves the time cost of the operation and directly reduces the construction cost and the cost of water injection operation.

[0003] However, pressure-operated operations also put forward requirements for the operation status of the pipe string during the operation. At present, whether it is drilling operations or downhole operations such as well repair, manual inspection and size measurement are carried out on the ground before the pipe string, drill pipe, oil casing, etc. enter the well, that is, the physical data such as the outer diameter and length of the pipe string entering the well are recorded. With the digitalization requirements of the oil and gas industry, equipment is constantly developing towards automation and intelligence, especially pressure-operated equipment, and the requirements for operations have been improved.

[0004] Some devices specially developed for pressure-operated machines to identify tubing couplings only display the identification of tubing couplings, resulting in distortion of sensor data, large detection deviation, and low reliability. Since the tubing will vibrate or shake when operating underground, and most of the current data acquisition devices cannot adapt to the shaking of the operating tubing underground, that is, the follow-up performance is poor, causing some data acquisition equipment to be separated from the tubing, resulting in distortion of some of the collected data. In addition, there is a lack of more comprehensive and systematic data acquisition equipment, and basic data such as movement speed and depth are not recorded, which cannot provide sufficient data support for automated and intelligent equipment. Summary of the invention

[0028] In order to better understand the purpose, structure and function of the present invention, the following Figures 1 to 4 , a wellhead data acquisition device for a pressure-operated pipe string of the present invention is further described in detail.

[0029] like Figures 1 to 4As shown, a device for collecting data at the wellhead of a pressure-operated pipe string according to an embodiment of the present invention includes an upper base plate 100, a lower base plate 200 and a device housing 300. One end of the device housing 300 is connected to the upper base plate 100, and the other end of the device housing 300 is connected to the lower base plate 200. A pipe string through hole 700 is also provided between the upper base plate 100 and the lower base plate 200, and the pipe string through hole 700 is used for the pipe string to pass through. A plurality of base plate mounting holes 800 are also provided on the upper base plate 100 and / or the lower base plate 200, and the base plate mounting holes 800 are used to mount the upper base plate 100 and / or the lower base plate 200 on other equipment. The upper base plate 100 and the lower base plate 200 can be connected to the device housing 300 by means of snap fastening, welding, etc.

[0030] The upper substrate 100 is also connected to the device inner shell 400 , and one end of the upper substrate 100 and the device inner shell 400 are movably connected through a plurality of rolling assemblies 500 ; the other end of the device inner shell 400 is movably connected to the lower substrate 200 through a plurality of rolling assemblies 500 .

[0031] Before the pressure operation on the pipe string, the wellhead data acquisition device for the pressure operation pipe string is installed at the inlet, and can form a series relationship with other equipment, such as being installed above the pressure operation machine. Since a plurality of base plate mounting holes 800 are provided on the upper base plate 100 and / or the lower base plate 200, the wellhead data acquisition device for the pressure operation pipe string can be installed and fixed through these base plate mounting holes 800.

[0032] The inner shell 400 of the device is arranged in the inner cavity of the outer shell 300 of the device. During pressure operation, the pipe string enters the inner cavity of the inner shell 400 of the device from the pipe string through hole 700 on the upper base plate 100, and then passes through the pipe string through hole 700 of the lower base plate 200. During the operation of the pipe string, the wellhead data acquisition device of the pipe string under pressure operation is always sleeved on the pipe string. When the pipe string continues to descend to the bottom of the well or rise to the wellhead, the length of a section of the pipe string is limited, generally about 9 meters, so the wellhead data acquisition device of the pipe string under pressure operation will be sleeved on the outer walls of different pipe strings. A connecting device will be used between the two pipe strings for detachable connection. Generally, a joint hoop is used to connect the two pipe strings, so that the outer diameter at the joint hoop will be slightly larger than the outer diameter of the pipe string. Usually the thickness of the joint hoop is about a few millimeters.

[0033] In the present invention, a data acquisition component is also provided on the device inner shell 400, and the data acquisition component is used to collect various data of the pipe string during use. The outer wall of the device inner shell 400 is provided with a plurality of fixed slider sliding outer grooves 410 in the axial direction, and the inner wall of the device inner shell 400 is provided with a plurality of fixed slider sliding inner grooves 420 in the axial direction. The device inner shell 400 is also provided with a plurality of fixed slider channels 430, and the fixed slider channels 430 connect the fixed slider sliding outer grooves 410 and the fixed slider sliding inner grooves 420, and two fixed slider channels 430 are provided on one fixed slider sliding outer groove 410.

[0034] The data acquisition assembly includes an outer fixed slider 411 and an inner fixed slider 421. The outer fixed slider 411 is slidably connected to the outer sliding groove 410 of the fixed slider, and the inner fixed slider 421 is slidably connected to the inner sliding groove 420 of the fixed slider. The outer fixed slider 411 and the inner fixed slider 421 are connected through a slider connecting rod 431, and the slider connecting rod 431 passes through the fixed slider channel 430. The slider connecting rod 431 is provided with an external thread, and the slider connecting rod 431 is threadedly connected to the outer fixed slider 411 and the inner fixed slider 421. The outer fixed slider 411 and the inner fixed slider 421 can be disassembled by a screw for detachable fixed connection, which is convenient for maintenance and replacement, and improves the service life of the wellhead data acquisition device for the pressure-operated pipe string.

[0035] The inner fixed slider 421 is rotatably connected with a data acquisition arm 610, and the two data acquisition arms 610 connected with two inner fixed sliders 421 slidably connected with the same fixed slider sliding inner groove 420 are rotatably connected with a rotating assembly 620, and the rotating assembly 620 and the two data acquisition arms 610 rotatably connected thereto form a V-shaped structure. The data acquisition arm 610 is connected with a sensor 640 at one end close to the rotating assembly 620, and the sensor 640 is used to collect some data during the use of the pipe string.

[0036] It should be noted that the outer fixed slider 411 near one end of the device inner shell 400 is fixedly connected to a synchronization ring 440, and the outer fixed slider 411 near the other end of the device inner shell 400 is fixedly connected to another synchronization ring 440. A plurality of return springs 630 are also provided between the two synchronization rings 440. A displacement sensor assembly 650 is also provided between the two synchronization rings 440.

[0037] After the pipe string passes through the wellhead data acquisition device for the pressure-operated pipe string, the outer wall of the pipe string keeps in contact with the rotating assembly 620 in the data acquisition assembly.

[0038] The shaking of the pipe string in some current data acquisition devices causes the acquisition device to be unable to stably contact the pipe string, resulting in distortion of the collected data. The displacement caused by this part of the shaking is a horizontal displacement. Therefore, several rolling components 500 are set at the place where the upper base plate 100 and the lower base plate 200 are connected to the device inner shell 400. When the pipe string in the well shakes, the pipe string will also drive the data acquisition component at the wellhead and the device inner shell 400 to move in the horizontal plane. The design of the rolling component 500 allows the device inner shell 400 and the data acquisition component to remain relatively still with the pipe string in the horizontal direction, and the rotating component 620 can always keep in contact with the outer wall of the pipe string, that is, the data acquisition component keeps in sync with the shaking of the pipe string, and the data acquisition component can always collect reliable data to ensure that there will be no data distortion caused by the separation of the rotating component 620 from the pipe string. The upper base plate 100, the lower base plate 200 and the device outer shell 300 move relative to the pipe string in the horizontal direction. It is equivalent to offsetting the shaking of the pipe string through the rolling component 500. The rolling assembly 500 used here can use a ball, or a component with a connecting rod and a ball, and the connecting rod part is arranged on the device inner shell 400. This design enables the wellhead data acquisition device for the pressurized operation pipe string to reduce the influence of the change in the direction of the pipe string shaking, and has strong tracking performance.

[0039] In some embodiments, a limiting groove is provided on a side of the upper substrate 100 and / or the lower substrate 200 facing the device inner shell 400, so that the rolling assembly 500 moves in the limiting groove to prevent the device inner shell 400 from moving out of the range of the upper substrate 100 and / or the lower substrate 200.

[0040] The abutment force of the rotating assembly 620 in the data acquisition assembly against the outer wall of the pipe column mainly comes from the reset spring 630. After the pipe column contacts the rotating assembly 620, it will squeeze the rotating assembly 620 toward the inner wall of the device inner shell 400. Since the rotating assembly 620 is rotatably connected to the two data acquisition arms 610, the ends of the two data acquisition arms 610 that are not connected to the rotating assembly 620 will move in a direction away from each other, and the end of the data acquisition arm 610 that is not connected to the rotating assembly 620 is rotatably connected to the inner fixed slider 421. At this time, the inner fixed slider 421 will slide along the fixed slider sliding inner groove 420, and the same fixed slider sliding inner groove 420 will slide in the opposite direction, thereby driving the two outer fixed sliders 411 on the same fixed slider sliding outer groove 410 to slide in the opposite direction, and then driving the synchronization ring 440 to move in the opposite direction, so that the reset spring 630 is opened, and at this time the reset spring 630 maintains a pulling force on the two synchronization rings 440. This pulling force will make the two synchronizer rings 440 tend to move toward each other, and the synchronizer rings 440 are connected to the outer fixed slider 411, and the outer fixed slider 411 is connected to the inner fixed slider 421, so the two inner fixed sliders 421 on the same fixed slider sliding inner groove 420 tend to slide toward each other. In addition, the two data acquisition arms 610 that are not connected to the rotating assembly 620 tend to move toward each other. Since the length of the data acquisition arm 610 is fixed, the rotating assembly 620 tends to move away from the device inner shell 400, that is, the rotating assembly 620 always maintains contact with the outer wall of the pipe column.

[0041] The rotating assembly 620 can always keep contact with the outer wall of the pipe column. In combination with the rolling assembly 500, when the pipe column shakes, the rotating assembly 620 can always keep contact with the outer wall of the pipe column, so that the data collected will never be distorted and is always reliable.

[0042] When the tubing string is rising or falling, its rising or falling speed data and length data are very important. If the speed control of the tubing string is unreasonable, it may cause damage to the tubing string, damage to related sensors, and even cause a blowout accident. In actual work, the drilled wells are often not vertical, but there are bends. When the tubing string speed is too high, the tubing string will hit the bends, causing damage to the supporting tools. In addition to speed, there is also an upward force in pressure operations. There are also control devices connected to the tubing string. Once the tubing string speed is out of a reasonable range, the control force needs to be increased. If the control force is not applied enough or not in time, a blowout accident will occur. At the same time, if the tubing string rises or falls too fast, it will also cause damage to the control equipment. Accurate speed detection can provide an accurate data source for the speed control of the tubing string.

[0043] In the present invention, the data such as the speed and length of the pipe string are obtained by driving the rotating assembly 620 to rotate during the ascent or descent of the pipe string, and the sensor 640 arranged next to the rotating assembly 620 will detect the rotation speed of the rotating assembly 620, and the current ascent or descent speed of the pipe string and the current length of the pipe string are obtained through the rotation speed of the rotating assembly 620. Not only can the data of the speed and length of the pipe string be measured, but more data can be obtained by changing the type of sensor 640 to detect the rotation of the rotating assembly 620 or directly obtaining more data through the sensor 640 instead of the rotation of the rotating assembly 620. For example, one or several of the sensors 640 can be replaced with non-destructive testing sensors to obtain data on the wall thickness or corrosion of the pipe string. Sufficient data support is provided for the control of the pipe string.

[0044] In some embodiments, the rotating assembly 620 can also be directly replaced by a rotatable sensor device, so that the rotating assembly 620 itself can also acquire part of the data of the pipe string, thereby improving the data acquisition efficiency of the wellhead data acquisition device for the entire pressurized operation pipe string.

[0045] When the pipe string is working in the well, it is also very important to identify the joint collar between the two pipe strings, because some operations need to avoid the joint collar to be performed, that is, some operations need to act directly on the pipe string. If the joint collar is acted on, it will cause damage to the joint collar or failure of the operation.

[0046] Some devices now use multiple detectors to detect the pipe string separately. Once the pipe string shakes, some of the detectors will be separated from the pipe string, resulting in deviation in the identification of the joint collar.

[0047] In the present invention, the designed synchronization ring 440 plays another important role. When the rotating assembly 620 encounters the hoop, when a part of the rotating assembly 620 retreats toward the inner wall of the device inner shell 400, due to the driving of the synchronization ring 440, all the data acquisition arms 610 will rotate relative to the inner fixed slider 421, and all the rotating assemblies 620 will retreat toward the inner wall of the device inner shell 400. At this time, the displacement sensor assembly 650 connected between the two synchronization rings 440 will detect the position change between the two synchronization rings 440.

[0048] The advantage of this design is that all the rotating components 620 retreat synchronously, and there will be no measurement deviation due to factors such as shaking, which will cause some parts to retreat and some parts to not retreat. During the operation, the thickness of the joint hoop used is generally millimeter-level or about 1 cm thick, and the position change data detected at the displacement sensor component 650 is larger than that directly detected at the rotating component 620. This makes the detection of the joint hoop more accurate. At the same time, since the size of the joint hoop used in an operation is known, the predicted size of the joint hoop is compared with the detected size to determine which ones are the joint hoop. Of course, before the joint hoop is lowered into the well, it is necessary to select the position of a joint hoop as the base point, and judge the position of the joint hoop based on the length of the downhole tubing and the mutual evidence of the displacement sensor component 650, thereby improving the accuracy of the judgment of the joint hoop position. At the same time, the operation process and device can also detect other tools attached to the tubing.

[0049] It can be understood that a plurality of data holes 660 are provided on the inner shell 400 of the device, and the data holes 660 are used for passing the first data cables 670 connected to the sensors 640 ; so that the data detected by each sensor 640 can be transmitted through the data cables 670 .

[0050] In addition, the displacement sensing assembly 650 is connected to a second data cable 680; the device housing 300 is provided with a data interface 690, to which the first data cable 670 and the second data cable 680 are fixedly connected, and the data interface 690 is used to transmit the data collected by the displacement sensing assembly 650 and / or the sensor 640. During the operation, the operator can read the various data collected by the wellhead data collection device of the pressure operation pipe string through the data interface 690.

[0051] The device housing 300 is also provided with a plurality of base plate mounting holes 800 , and the base plate mounting holes 800 are used to mount the device housing 300 on other equipment, such as a belt pressure working machine.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
