Abstract
Description
Technical Field
[0001] This invention relates to the field of continuous tube stacking technology, and in particular to a continuous tube stacking method. Background Technology
[0002] A coiled tubing installer is a widely used oilfield equipment for well workover, drilling, and acid fracturing, often referred to as a "universal installer." A coiled tubing installer typically consists of key components such as an injection head, control chamber, drum, and coiled tubing. The drum, a crucial component, is primarily used for winding and transporting the coiled tubing. Before the coiled tubing installer is deployed to the field, a tubing rewinder is used to wind the coiled tubing from the transport drum onto the coiled tubing installer's drum. This process, known as "tube winding," ensures the tubing is neatly wound layer by layer onto the drum. Current tube winding systems primarily utilize a tube winding system with two methods: automatic and forced winding. Automatic winding relies on the drum's rotation driving a rhombus shaft, which in turn moves a sliding trolley horizontally to complete the winding. Forced winding uses a hydraulic motor at one end of the straight arm of the winding device to drive a pair of sprockets, forcibly rotating the rhombus shaft and manually changing the horizontal position of the sliding trolley to complete the winding. In actual operation, automatic pipe laying is usually the main method, and forced pipe laying is the auxiliary method. Automatic pipe laying is generally used, while forced pipe laying is used when the continuous pipe is being wound and changed layers.
[0003] In actual operation, when the continuous tube is winding and transitioning near the edge of the drum spokes, the winding angle is prone to deviation. When manually identifying, judging, and forcibly winding the tube to correct the winding angle, due to the complexity of the actual working conditions and the lack of a standardized operating procedure, even experienced operators are prone to inaccurate judgment, improper handling, or delays. This cannot guarantee that the continuous tube can be wound neatly and smoothly into the drum every time, resulting in subsequent tube winding disorder. Once the continuous tube is wound disordered, it will lead to external wear of the tube body, reduced drum coil capacity, reduced tube life, and repeated winding of the continuous tube.
[0004] Therefore, it is necessary to develop a continuous tube arrangement method to overcome the above-mentioned technical problems. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a continuous pipe arrangement method, which effectively overcomes the defects of the prior art.
[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:
[0007] A continuous tube arrangement method includes the following steps:
[0008] Step 1: Preparations before pipe laying, as follows:
[0009] Move the transport roller to the vicinity of the continuous pipe machine and make its axis parallel to the axis of the pipe-laying roller on the continuous pipe machine, and ensure that the vertical distance between the axes of the transport roller and the pipe-laying roller meets the set requirements.
[0010] Step 2: Pass the continuous tube from the transport roller through the counter of the pipe-laying roller and insert it into the inlet of one end of the pipe-laying roller, which is close to the end of the flange.
[0011] Step 3: Lay out the first layer of continuous tubing, as follows:
[0012] Begin winding the continuous tube from the transport roller onto the pipe-laying roller. After winding one turn of continuous tube onto the pipe-laying roller, pause the winding and adjust the first three-quarters of the turn to be flush against one end of the pipe-laying roller. The starting point of the last quarter turn should be tilted. When the first turn of the first layer of continuous tube enters the second turn, an angle will be formed between the first turn and the second turn. Continue winding, using an automatic pipe-laying method to continue winding the second turn, the third turn, and so on onto the pipe-laying roller until the last turn. Ensure that the gap between the first three-quarters of the last turn of continuous tube and the other end of the pipe-laying roller does not exceed half the diameter of the continuous tube.
[0013] Step 4: Install the second layer of continuous tubing, as follows:
[0014] After the first coil of the second layer starts to arc, the line connecting the arc starting point of the second layer and the outlet position of the coil is made perpendicular to the web. After the second layer starts to arc, the forced coil winding is activated, and the counter is adjusted to move towards the other web, so that the coil contacts and maintains contact with the other web. As the coil winding drum rotates, the coil located on the transport drum continues to be wound on the coil winding drum. When the first three-quarters of the first coil of the second layer enters the coil winding drum, the counter is moved towards one web to guide the coil into the gap of the last two coils of the first layer. The coil begins to wind the second coil. At the same time, the forced coil winding is turned off, and the automatic coil winding method is used to continue winding the second coil, the third coil, and so on onto the drum.
[0015] Step 5: Arrange the third layer of continuous tubing, as follows:
[0016] After the first continuous tube of the third layer starts to arc, forced tube winding begins. By adjusting the counter to move towards one end of the loop, the continuous tube contacts and maintains contact with the end loop, continuing to wind the roller. When the first continuous tube of the third layer turns into the second loop, forced tube winding guides the continuous tube into the gap of the previous continuous tube along the trajectory of the first continuous tube. The forced tube winding is then adjusted to automatic tube winding, and the continuous tube continues to wind along the gap on the winding roller until the tube winding of the third layer is completed.
[0017] Step 6: Arrange the fourth layer of continuous tubing, as follows:
[0018] After the first coil of the fourth layer begins to arc, forced coil winding begins. By adjusting the counter, the coil is moved to the other end of the coil, so that the coil contacts and maintains contact with the other end of the coil, and continues to wind the coiling roller. When the first coil of the fourth layer turns into the second coil, the coil is guided into the gap of the previous layer of coil along the trajectory of the second layer of coil. The forced coil winding is then adjusted to automatic coil winding, and the coil continues to wind along the gap of the coiling roller until the coiling of the fourth layer is completed.
[0019] Step 7: Arrange the continuous pipes for the subsequent layers. For odd-numbered layers, arrange the pipes according to Step 5, and for even-numbered layers, arrange the pipes according to Step 6.
[0020] Based on the above technical solution, the present invention can be further improved as follows.
[0021] Furthermore, in step one above, the vertical distance between the axes of the continuous pipe transport roller and the pipe laying roller is set to H, and H is not less than 15m.
[0022] Furthermore, H = 15m above.
[0023] Furthermore, the aforementioned ring includes an inner ring and an outer ring. The inner ring is coaxially fixed to the end of the roller body, and the outer ring is coaxially sleeved outside the inner ring. Multiple connecting rods are circumferentially connected between the inner ring and the outer ring, and all of the connecting rods extend radially along the roller body.
[0024] Furthermore, the number of the aforementioned connecting rods is 16.
[0025] Furthermore, in step three above, the method to ensure that the gap between the first three-quarters of the last continuous tube and the other end of the tube roll does not exceed half the diameter of the continuous tube is as follows: if the gap is too large or too small, the continuous tube needs to be put back onto the transport roller and then rewound.
[0026] Furthermore, in step three above, the method to ensure that the gap between the first three-quarters of the last continuous tube and the other end of the tube-laying roller does not exceed half the diameter of the continuous tube is as follows: if the gap is too large or too small, use a pry bar to adjust the gap between the continuous tubes on the tube-laying roller.
[0027] Furthermore, in step three above, ensure that the gap between the first three-quarters of the last continuous tube and the other end of the tube-laying roller is 1 / 3 to 1 / 2 of the continuous tube diameter.
[0028] Furthermore, in step three above, an angle α will be formed between the first ring and the second ring of the first layer, and 3°≤α≤10°.
[0029] Furthermore, the aforementioned pipe-laying roller is mounted on the continuous pipe machine via a square-shaped base connected to its two end rings.
[0030] The beneficial effects of this invention are: it can neatly wind continuous tubes onto the tube-laying drum without changing existing components and equipment such as tube rewinders and drum equipment, thus avoiding the harms of external wear of the tube body, reduced drum coil capacity, and reduced service life of continuous tubes caused by disordered continuous tube laying.

[0041] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0042] Example: The pipe-laying roller 2 designed in the continuous pipe laying method of this example is a product of the prior art. It generally includes a roller body (g1 in the figure), a shaft coaxially passing through the roller body (g2 in the figure), one end of the shaft connected to a transmission device (such as a motor, as shown in g3 in the figure), and two flanges (such as...) coaxially mounted at both ends of the roller body. Figure 1 , 2 (As shown). The aforementioned flanges include an inner ring and an outer ring. The inner ring is coaxially fixed to the end of the roller body, and the outer ring is coaxially sleeved outside the inner ring. Multiple connecting rods 211 are circumferentially spaced between the inner and outer rings, and each connecting rod 211 extends radially along the roller body. There are 16 connecting rods 211 in total. The angle between any two adjacent connecting rods is 22.5°. The uppermost connecting rod 211 is designated as #1, and the remaining connecting rods 211 are designated as #2, #3, #4... #16 in a clockwise direction. The connecting rod 211 at the inlet, closest to the surface of the pipe-laying roller 2, is designated as rod #1. The pipe-laying roller 2 is mounted on the continuous pipe processing machine via a square-frame base connected to its two end flanges.
[0043] The continuous tube routing method specifically includes the following steps:
[0044] Step 1: Preparations before pipe laying, as follows:
[0045] Select a flat site and arrange the transport roller 1 and the pipe reversing device (a in the diagram) as follows: Move the transport roller 1 near the continuous pipe machine, ensuring that the axis of the transport roller 1 is parallel to the axis of the pipe reversing roller 2 on the continuous pipe machine, and ensure that the vertical distance between the axes of the transport roller 1 and the pipe reversing roller 2 meets the set requirements (refer to the appendix for specific layout). Figure 3 The distance between the two is set to H, and H is not less than 15m, preferably 15m. The transport roller 1 is installed on the pipe reversing device, and the pipe laying roller 2 is installed on the continuous pipe operating machine. Both the transport roller 1 and the pipe laying roller 2 are equipped with counters 23 (which are existing technologies and will not be described in detail here). The purpose is to change the vertical position of the continuous pipe by moving the counters 23 up and down when forced pipe laying is used, thereby changing the position of the continuous pipe wound on the pipe laying roller 2 (which are existing technologies and will not be described in detail here).
[0046] Step 2: Pass the continuous tube (represented by b in the figure) coming out of the transport roller 1 through the counter 23 of the pipe laying roller 2, and insert it into the inlet (represented by c in the figure) of the pipe laying roller 2, which is close to the surface of one end of the pipe laying roller 2.
[0047] Step 3: Lay out the first layer of continuous tubing, as follows:
[0048] Begin winding the continuous tube from transport roller 1 onto pipe-laying roller 2. After winding one turn of continuous tube onto pipe-laying roller 2, pause the winding and adjust the first three-quarters of the turn of continuous tube to be flush against one end of the web of pipe-laying roller 2 (the specific adjustment method is: manually tap the first turn of continuous tube before position 13 on the roller to make it flush against one end of the web). The starting point of the last quarter turn begins to tilt. When the first turn of the first layer of continuous tube (represented by z1 in the diagram) enters the second turn (starting from position 1, represented by ② in the diagram), an angle α will be formed between the first turn and the second turn of the first layer, and 3°≤α≤10° (this angle is the angle between the tangent at the tilted position of the first turn of the first layer of continuous tube before and after position 13 and the central axis of the continuous tube flush against one end of the web). Continue winding, using an automatic pipe-laying method to continue winding onto the pipe-laying roller. 2. Wind the continuous tube on the transport roller 1 for the second, third, and so on, until the last turn (zn in the diagram). Pause rotating the pipe roller 2 and observe the continuous tube wound on it. Observe the gap between the last turn of the first layer of the continuous tube before pole position #13 (total number of turns = inner width of pipe roller 2 / continuous tube diameter - 1) and the other end of the continuous tube (d in the diagram). Ensure the gap is between 1 / 3 and 1 / 2 of the tube diameter. If the gap is too large or too small, return the continuous tube to the transport roller 1 and rewind. Alternatively, if the gap is too large or too small, use a copper pry bar to adjust the gap between the continuous tubes on the pipe roller 2. This is to ensure that the first continuous tube of the second layer can stably fall into the gap between the last turn of the first layer and the other end of the continuous tube, without slipping out of the gap (see [link to details on the arrangement of the first layer of continuous tubes]). Figure 4 ,and Figure 5 );
[0049] Step 4: Install the second layer of continuous tubing, as follows:
[0050] After the first layer of continuous tubes is laid, the second layer of continuous tubes is laid, and an arc is initiated, ensuring that the line connecting the arc initiation point of the second layer and the outlet position of the continuous tube is perpendicular to the winding coil. After the arc initiation of the second layer, forced tube laying is activated, and counter 23 is adjusted to move towards the other winding coil, so that the continuous tube contacts and maintains contact with the other winding coil. As the tube laying roller 2 rotates, the continuous tube located on the transport roller 1 continues to be wound on the tube laying roller 2. When the first three-quarters of the first turn of the second layer (represented by q in the diagram) of the continuous tube enters the tube laying roller 2, counter 23 is moved towards one winding coil, guiding the continuous tube into the gap of the last two turns of the first layer (represented by f in the diagram), and the continuous tube begins to wind the second turn (represented by y in the diagram). At the same time, forced tube laying is deactivated, and automatic tube laying continues to wind the second turn, the third turn, and so on onto the roller using an automatic tube laying method. (See Appendix for the second layer of tube laying) Figure 6 (as shown);
[0051] It should be noted that the process of winding the continuous tube from the first turn of the second layer into the second turn of the second layer must be completed before the #1 position. When the first turn of the second layer of continuous tube is wound into the second turn, an angle (angle β) will be formed between the first turn and the second turn. This angle is the angle between the tangent at the inclined position of the first turn of the second layer of continuous tube before and after the #13 position and the central axis of the continuous tube closely attached to the other end. This angle must be close to the angle between the first turn and the second turn of the first layer of continuous tube (i.e., angle α).
[0052] Step 5: Arrange the third layer of continuous tubing, as follows:
[0053] After the first continuous loop of the third layer (represented by m1 in the diagram) begins to arc, forced tube winding begins. Counter 23 is adjusted to move towards one end loop, ensuring the continuous tube contacts and maintains contact with the end loop, continuing to wind the roller. When the third layer of continuous tube transitions from the first loop to the second loop (represented by m2 in the diagram), forced tube winding guides the continuous tube along the trajectory of the first layer into the gap of the previous layer (the continuous tube must completely enter the second loop before the #1 rod position). Forced tube winding is then switched to automatic winding, and the continuous tube continues to wind along the gap on the winding roller 2 until the third layer of tube winding is completed (see section 2 for the winding of the third layer of continuous tube). Figure 7 (as shown);
[0054] Step 6: Arrange the fourth layer of continuous tubing, as follows:
[0055] After the first coil of the fourth layer (p1 in the diagram refers to the first coil of the fourth layer, and p2 in the second coil refers to the second coil) begins to arc, forced coil winding begins. By adjusting counter 23, the coil is moved to the other end of the coil, so that the coil contacts and maintains contact with the other end of the coil, and continues to wind the coil winding roller 2. When the fourth layer of coil turns from the first coil to the second coil, it follows the trajectory of the second layer of coil and is guided into the gap s of the upper layer of coil by forced coil winding (wherein, the coil must completely enter the second coil from the first coil before the #1 pole position). The forced coil winding is adjusted to automatic coil winding, and the coil continues to wind the coil winding roller 2 along the gap until the coil winding of the fourth layer is completed (see the coil winding of the fourth layer of coil). Figure 8 (as shown);
[0056] Step 7: Arrange the continuous pipes for the subsequent layers. For odd-numbered layers, arrange the pipes according to Step 5, and for even-numbered layers, arrange the pipes according to Step 6.
[0057] In this embodiment, the continuous tube winding method can neatly wind the continuous tube onto the winding drum 2 without changing the existing components and equipment such as the tube rewinder and drum equipment. This avoids the damage caused by disordered continuous tube winding, such as external wear of the tube body, reduced drum coil capacity, and reduced service life of the continuous tube.
[0058] It should be further explained that in this embodiment, "the arc starting point of the Xth layer" and "arc starting" (X≥2) are defined as follows: when the continuous tube closest to the radial loop in the Xth layer cannot completely fall into the gap between the continuous tubes of the X-1th layer, or in other words, when the distance L between the continuous tube closest to the radial loop in the Xth layer and the radial loop is exactly equal to the radius D of the continuous tube, the position of the tube cross-section (located on the radial loop) of the continuous tube is called the arc starting point. The following example illustrates the case where X=2. Figure 4 As shown, from time t1 to time t3, as the drum gradually rotates, the continuous tube is wound around the drum. The distance L between the continuous tube closest to the other end of the first layer and the other end of the drum gradually decreases. When L decreases to the radius D of the continuous tube, the continuous tube will arch up at the next moment. At this moment, the position of the tube section of the continuous tube (position A on the drum) is called the arc starting point of the second layer. The action of the continuous tube arching up is called arc starting.
