Description

Technical Field

[0001] The invention relates to the technical field of oil and gas field development, and in particular to a mud scraper fixing device. Background Art

[0002] In oil and gas field logging operations, when the cable is lowered with the drill bit, part of the cable lowered into the well will be stained with drilling fluid. When the cable is pulled up with the drill bit, the drilling fluid on the cable will be scattered in the well site, causing pollution. If the drilling fluid on the cable is not handled cleanly, the mission life of the cable will be seriously reduced. Therefore, in order to ensure the service life of the cable and protect the well site environment, the cable must be cleaned during the cable lifting process.

[0003] Because the cable passes through the guide rails and pulleys, it has a certain inclination angle with the vertical direction when it is lifted to the well. The commonly used scraper cannot clean the inclined cable. At present, a rubber hose with steel wire is usually used for scraping mud. The staff wraps the soft hose with steel wire around the inclined cable. During the cable lifting process, the friction between the soft hose and the cable plays a role in scraping mud. However, when cleaning the cable by friction, if the soft hose is wrapped too tightly, it will hinder the cable from being lifted and easily wear the cable. If it is wrapped too loosely, the cleaning effect is poor. Summary of the invention

[0041] In order to solve the problem of poor cleaning effect of inclined cables in the prior art, an embodiment of the present invention provides a scraper fixing device. During use of the scraper fixing device, the scraper clamp is used to connect the scraper; the positioning assembly is connected to the positioning portion on the well, and the adjusting rod can rotate around the connection with the positioning assembly to drive the scraper clamp connected thereto to rotate, thereby driving the scraper connected to the scraper clamp to rotate to adjust the angle of the scraper; the length of the adjusting rod can be adjusted to make the scraper clamp connected thereto move away from or close to the positioning assembly, thereby moving the scraper connected to the scraper clamp to facilitate cooperation with the inclined cable to be cleaned and performing cleaning operations, thereby solving the problem of poor cleaning effect of the inclined cable in the prior art.

[0042] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0043] See also Figure 1 and Figure 4 The scraper fixing device provided in an embodiment of the present invention includes a positioning assembly, an adjusting rod 500 and a scraper clamp 600, wherein the positioning assembly is used to connect with the positioning position on the well; the length of the adjusting rod 500 is adjustable, one end of the adjusting rod 500 is rotatably connected to the positioning assembly, and the other end of the adjusting rod 500 is connected to the scraper clamp 600; the scraper clamp 600 is used to connect with the scraper 700.

[0044] Specifically, in this embodiment, the positioning assembly is used to connect the scraper fixture as a whole to the positioning position set on the well. The selection of the positioning position on the well can be selected according to the position of the cable to be cleaned and the inclination angle and inclination direction of the cable. For example, the positioning assembly can be connected to the seat bucket on the well, the equipment on the well, or the screws or bolts fixed on the well to determine the orientation of the scraper fixture as a whole, and then connected to the scraper 700 to clean the target cable. In this embodiment, the positioning assembly can be configured to cooperate with bolts and nuts to be fixedly connected to the positioning position set on the well, or it can be configured to one or more clamps to clamp the equipment at the positioning position. The setting of the positioning assembly in this embodiment facilitates the fixing of the position of the scraper fixture as a whole before cleaning, and at the same time facilitates the staff to flexibly select the fixed orientation, and also facilitates the cleaning of the cable.

[0045] One end of the adjusting rod 500 is connected to the positioning assembly. Specifically, the adjusting rod 500 can be set as a cylinder or a sleeve rod combination. For example, the adjusting rod 500 is set as a sleeve rod combination, and the adjusting rod 500 includes an inner rod and a rod sleeve sleeved on the inner rod. The inner rod and the rod sleeve can be connected by threads, and the inner rod and the rod sleeve can generate relative motion by rotation, thereby changing the overall length of the adjusting rod 500; the inner rod and the rod sleeve can also be set as a sliding connection. Specifically, a blind hole can be set on the inner rod, and a pin and a spring that cooperates with the pin are set in the blind hole. A plurality of through holes are correspondingly set on the rod sleeve. The overall length of the adjusting rod 500 is changed by the cooperation between the pin and different through holes. In this embodiment, the length of the adjusting rod 500 can be adjusted. When the positioning assembly is connected to the positioning position on the well, the adjusting rod 500 can change the distance from the cable by extending or shortening, thereby facilitating the cleaning of the cable.

[0046] like Figure 1As shown, the adjusting rod 500 is connected to the positioning assembly by rotational connection. When the positioning assembly is connected to the positioning position on the well, the adjusting rod 500 can rotate relative to the positioning assembly to adjust the angle, which is convenient for subsequent cleaning of the cable. There are many ways of rotational connection. For example, a threaded hole is provided on the positioning assembly, and a through hole is provided at one end of the adjusting rod 500. The through hole is aligned with the threaded hole. The adjusting rod 500 is rotationally connected to the positioning assembly by a bolt that passes through the threaded hole and the through hole in sequence. For another example, a pin seat is provided on the positioning assembly, and a pin is provided at one end of the adjusting rod 500 perpendicular to the axial direction of the adjusting rod 500. The pin cooperates with the pin seat, so that the adjusting rod 500 and the positioning assembly can rotate relative to each other.

[0047] The other end of the adjusting rod 500 is connected to the scraper clamp 600, and the connection mode can be a fixed connection or a rotating connection. Figure 2 As shown, in this embodiment, the scraper clamp 600 is used to connect with the scraper 700 to fix the scraper 700. The scraper 700 can be a vertical well logging scraper, and the column part of the scraper 700 cooperates with the scraper clamp 600.

[0048] In this embodiment, the adjusting rod 500 can drive the scraper clamp 600 to move. Specifically, when the adjusting rod 500 rotates relative to the positioning assembly, the scraper clamp 600 fixedly connected to one end of the adjusting rod 500 can rotate relative to the positioning assembly with the adjusting rod 500; when the length of the adjusting rod 500 changes, the distance between the end of the adjusting rod 500 away from the positioning assembly and the positioning assembly changes. Accordingly, the scraper clamp 600 fixedly connected to one end of the adjusting rod 500 can move closer to or farther from the positioning assembly as the length of the adjusting rod 500 changes. In this embodiment, the scraper 700 is installed in the scraper clamp 600, and the scraper clamp 600 can move with the adjusting rod 500, so that the scraper 700 can be sleeved on the cable to be cleaned.

[0049] like Figure 4 As shown, the connection between the scraper clamp 600 and the vertical well logging scraper is described as an example. After the positioning assembly is fixed, the adjusting rod 500 can be rotated relative to the positioning assembly to make the axial direction of the through hole 710 on the vertical well logging scraper parallel to the axial direction of the cable, and then the adjusting rod 500 is stretched to make the vertical well logging scraper reach the position where the cable can pass through the through hole 710, and then the cable is passed through the through hole 710, and then the vertical well logging scraper is started to clean the cable.

[0050] To summarize, during use of the scraper fixing device provided in the present embodiment, the scraper 700 is connected to the scraper clamp 600; the positioning assembly is connected to the positioning portion on the well, and the adjusting rod 500 can rotate around the connection with the positioning assembly to drive the scraper clamp 600 connected thereto to rotate, thereby being able to drive the scraper 700 connected to the scraper clamp 600 to rotate to adjust the orientation of the scraper 700; the length of the adjusting rod 500 can be adjusted so that the scraper clamp connected thereto moves away from or close to the positioning assembly, thereby moving the scraper 700 connected to the scraper clamp 600. Therefore, the scraper fixing device provided in the present embodiment can be fixed on the well, and the orientation of the scraper 700 can be adjusted by the adjusting rod 500, so that the scraper 700 is easy to cooperate with the cable to be cleaned to clean the cable, thereby solving the problem of poor cleaning effect of inclined cables in the prior art.

[0051] Further, in a possible implementation, the positioning assembly includes a clamping ring, the clamping ring includes a first clamping plate 100 and a second clamping plate 200 that are arranged opposite to each other, and the first clamping plate 100 and the second clamping plate 200 are detachably connected. In this embodiment, the clamping ring is used to clamp on a device or equipment at a well positioning position, preferably, it can be clamped on a seat bucket on the well, the clamping ring includes a first clamping plate 100 and a second clamping plate 200, and the first clamping plate 100 and the second clamping plate 200 are arranged opposite to each other. There are many ways to set the shape of the clamping ring, for example, the shape of the clamping ring can be set to a circle or an ellipse, in which case the shapes of the first clamping plate 100 and the second clamping plate 200 are both set to a semicircle or an arc; for another example, the shape of the clamping ring can be set to a semicircle, in which case the first clamping plate 100 is set to an arc, and the second clamping plate 200 is set to a strip; for another example, the shape of the clamping ring can be set to a rectangle, and the first clamping plate 100 and the second clamping plate 200 are both set to a rectangular frame.

[0052] The first clamping plate 100 and the second clamping plate 200 are detachably connected. Specifically, the first clamping plate 100 and the second clamping plate 200 can be configured to be clamped, or can be configured to be connected by bolts, or can be configured to be connected by a pin. In this embodiment, the first clamping plate 100 and the second clamping plate 200 are configured to be detachably connected, which is convenient for the positioning assembly to be connected to the equipment at the well positioning location, and also convenient for the staff to adjust the position of the positioning assembly.

[0053] On the basis of the above-mentioned embodiments, preferably, the first clamping plate 100 and the second clamping plate 200 are arc-shaped clamping plates. In this embodiment, the first clamping plate 100 and the second clamping plate 200 are arranged in a mirror image, and the two ends of the first clamping plate 100 are respectively aligned with the two ends of the second clamping plate 200 and connected. Such an arrangement ensures the stability of the clamping ring clamped on the positioning device. In addition, the side walls opposite to the first clamping plate 100 and the second clamping plate 200 can also be provided with concave-convex stripes or a rubber pad with concave-convex stripes can be pasted, so that when clamping the positioning device, the friction between the device and the positioning device can be increased, and the firmness of the clamping can be further improved.

[0054] Furthermore, in a possible implementation, the positioning assembly also includes two nuts; both ends of the first clamping plate 100 are provided with first connecting blocks 110 extending radially along the clamping ring, wherein the first connecting block 110 at one end is provided with a first threaded rod 120, and the first connecting block 110 at the other end is provided with a first through hole 130; both ends of the second clamping plate 200 are provided with second connecting blocks 210 extending radially along the clamping ring, wherein the second connecting block 210 at one end is provided with a second threaded rod 220, and the second connecting block 210 at the other end is provided with a second through hole 230; the first threaded rod 120 extends into the second through hole 230 and cooperates with the nut; the second threaded rod 220 extends into the first through hole 130 and cooperates with the nut.

[0055] Specifically, Figure 1 and Figure 2 As shown, the first clamping plate 100 and the second clamping plate 200 are both arranged in an arc shape, and the first connecting blocks 110 are respectively arranged at both ends of the first clamping plate 100, and the second connecting blocks 210 are respectively arranged at both ends of the second clamping plate 200. The two first connecting blocks 110 are respectively aligned and connected with the two second connecting blocks 210. In this embodiment, the connection method is to connect the threaded rod with the threaded hole. Specifically, a first through hole 130 is arranged on one of the first connecting blocks 110, and a first threaded rod 120 is arranged on the other first connecting block 110, and the first threaded rod 120 is welded to the first connecting block 110; correspondingly, a second threaded rod 220 is arranged on one of the second connecting blocks 210, and the second threaded rod 220 is welded to the second connecting block 210, and the second through hole 230 is arranged on the other second connecting block 210. In this embodiment, the first connecting block 110 can be set as a metal block, connected to the first clamping plate 100 by welding, or formed on the first clamping plate 100 by integral molding; the second connecting block 210 can be set as a metal block, connected to the second clamping plate 200 by welding, or formed on the second clamping plate 200 by integral molding.

[0056] On the basis of the above embodiment, the first threaded rod 120 passes through the second through hole 230, and a nut is connected to the rod section of the first threaded rod 120 extending from the second through hole 230; the second threaded rod 220 passes through the first through hole 130, and a nut is connected to the rod section of the second threaded rod 220 extending from the first through hole 130. When the clamping ring clamps the equipment at the positioning location, the staff can unscrew the nut to separate the first clamping plate 100 from the second clamping plate 200, and then dock the first clamping plate 100 and the second clamping plate 200 on the equipment at the positioning location, so that the first threaded rod 120 passes through the second through hole 230 and the second threaded rod 220 passes through the first through hole 130, and then screw nuts on the first threaded rod 120 and the second threaded rod 220, respectively, so as to connect the first clamping plate 100 and the second clamping plate 200 together. Such a setting structure is simple and has high connection reliability, which is convenient for clamping the clamping ring on the equipment at the positioning location. In addition, one of the two ends connecting the first clamping plate 100 and the second clamping plate 200 may be configured to be hinged, and the other end may be configured to be connected by a threaded rod in cooperation with a threaded hole.

[0057] The positioning assembly is rotatably connected to one end of the adjusting rod 500. Specifically, the adjusting rod 500 is connected to the clamping ring in the positioning assembly. In a possible implementation, Figure 2 As shown, a third connecting block 300 is provided on the outer wall of the second clamping plate 200, and a first connecting hole 310 is provided on the third connecting block 300. The axis of the first connecting hole 310 is perpendicular to the axis of the first through hole 130, and one end of the adjusting rod 500 is connected to the first connecting hole 310 by a bolt. In this embodiment, one end of the adjusting rod 500 is connected to the second clamping plate 200, specifically, as shown in FIG. Figure 1 and Figure 2 As shown, a third connecting block 300 is arranged on the outer wall of the second clamping plate 200. The third connecting block 300 and the second clamping plate 200 can be connected by welding or by an integrally formed structure. Preferably, the third connecting block 300 is welded to the center of the second clamping plate 200. Such an arrangement avoids interference of the adjusting rod 500 with the opening and closing of the clamping ring, while ensuring the reliability of the connection.

[0058] On the basis of the above embodiment, the third connection block 300 is provided with a first connection hole 310 for connecting with the adjustment rod 500. Figure 2As shown, the axis of the first connecting hole 310 is perpendicular to the axis of the first through hole 130 on the first clamping plate 100. The first connecting hole 310 can be a through hole or a threaded hole. This embodiment is described by taking the first connecting hole 310 as a through hole as an example. One end of the adjusting rod 500 is correspondingly provided with a threaded hole that matches the first connecting hole 310. The axis of the threaded hole on the adjusting rod 500 coincides with the axis of the first connecting hole 310, and the axis of the threaded hole is perpendicular to the axis of the adjusting rod 500. Such a setting enables the adjusting rod 500 to rotate around the connection, and the plane where the rotation direction is located is perpendicular to the plane where the clamping ring is located, which is convenient for subsequent adjustment of the angle between the adjusting rod 500 and the clamping ring.

[0059] Furthermore, in a possible implementation, the scraper clamp 600 is configured to be cylindrical, and the side wall of the scraper clamp 600 is provided with openings 610 that penetrate through both ends in the axial direction. The scraper clamp 600 is used to connect with the scraper 700. The commonly used scraper 700 includes a column part. In this embodiment, the scraper clamp 600 is configured to be cylindrical, and the cylindrical scraper clamp 600 is used to clamp the column of the scraper 700. Specifically, Figure 4 As shown, the column of the scraper 700 extends into the cylindrical scraper clamp 600, and an opening 610 is provided on the side wall of the scraper clamp 600. Such a configuration makes it easy for the column of the scraper 700 to extend therein, and the column of the scraper 700 is clamped after the column is extended therein. In addition, the scraper clamp 600 in this embodiment can also be configured as an openable and closable structure. When the scraper clamp 600 is opened, the column of the scraper 700 extends into the scraper clamp 600, and then the scraper clamp 600 is closed to lock the column of the scraper 700 therein.

[0060] Further, on the basis of the above-mentioned embodiment, the scraper clamp 600 is cylindrical, and the inner diameter of the scraper clamp 600 is smaller than the outer diameter of the column of the scraper 700. The column of the scraper 700 cooperates with the scraper clamp 600, and an opening 610 is axially arranged on the side wall of the scraper clamp 600. When the column of the scraper 700 extends into the scraper clamp 600, the scraper clamp 600 expands from the opening 610 to both sides, so that the column of the scraper 700 can be easily extended. In this embodiment, the inner diameter of the scraper clamp 600 is smaller than the outer diameter of the column of the scraper 700, which ensures that the scraper clamp 600 and the column of the scraper 700 are closely matched.

[0061] Further, in a possible implementation, the end of the adjusting rod 500 away from the positioning assembly is fixedly connected to the scraper clamp 600. The two ends of the adjusting rod 500 are respectively connected to the positioning assembly and the scraper clamp 600. On the basis of the above-mentioned implementation, the adjusting rod 500 is rotatably connected to the positioning assembly. In this embodiment, the end of the adjusting rod 500 away from the positioning assembly is fixedly connected to the scraper clamp 600. The fixed connection method can be set to welding or bolt connection. When the positioning assembly is fixed to the positioning position set on the well, the adjusting rod 500 connected to the positioning assembly can rotate around the connection. At the same time, the scraper clamp 600 fixedly connected to the adjusting rod 500 can rotate with the rotation of the adjusting rod 500, so that the scraper 700 connected to the scraper clamp 600 can rotate, and the cable can be cleaned by adjusting the angle between the vertical direction.

[0062] Furthermore, in another possible implementation, one end of the adjusting rod 500 away from the positioning assembly is rotatably connected to the scraper clamp 600 , and the scraper clamp 600 and the positioning assembly can rotate in the same plane relative to the adjusting rod 500 . The two ends of the adjusting rod 500 are respectively connected to the positioning assembly and the scraper clamp 600. On the basis of the above-mentioned embodiment, the adjusting rod 500 is rotatably connected to the positioning assembly. In this embodiment, the end of the adjusting rod 500 facing away from the positioning assembly is rotatably connected to the scraper clamp 600. When the positioning assembly is fixed at a positioning position set on the well, the adjusting rod 500 connected to the positioning assembly can rotate around the connection. At the same time, the scraper clamp 600 rotatably connected to the adjusting rod 500 can rotate with the rotation of the adjusting rod 500 and can rotate around the connection with the adjusting rod 500. The rotation direction of the scraper clamp 600 relative to the adjusting rod 500 and the rotation direction of the positioning assembly relative to the adjusting rod 500 are located in the same plane. Such an arrangement enables the scraper 700 connected to the scraper clamp 600 to rotate to adjust the angle with the vertical direction, thereby further improving the convenience of angle adjustment and making it easier for the scraper 700 to clean cables with a certain inclination angle.

[0063] There are many ways to rotatably connect the adjusting rod 500 and the scraper clamp 600. Specifically, in one possible implementation, Figure 3As shown, a fourth connecting block 400 is provided on the outer wall of the scraper clamp 600, and a second connecting hole 410 is provided on the fourth connecting block 400. One end of the adjusting rod 500 is connected to the second connecting hole 410 by a bolt. A fourth connecting block 400 is provided on the outer wall of the scraper clamp 600 on the side close to the adjusting rod 500. The fourth connecting block 400 and the scraper clamp 600 can be connected by welding or by an integrally formed structure. Preferably, the fourth connecting block 400 is welded to the scraper clamp 600. Such a configuration ensures the reliability of the connection. A second connecting hole 410 for connecting to the adjusting rod 500 is provided on the fourth connecting block 400. Figure 3 and Figure 4 As shown, the axis of the second connecting hole 410 is perpendicular to the axis of the cylindrical scraper clamp 600. The second connecting hole 410 can be a through hole or a threaded hole. This embodiment is described by taking the second connecting hole 410 as a through hole as an example. One end of the adjusting rod 500 is correspondingly provided with a threaded hole that matches the second connecting hole 410. The axis of the threaded hole on the adjusting rod 500 coincides with the axis of the second connecting hole 410, and the axis of the threaded hole is perpendicular to the axis of the adjusting rod 500. This arrangement enables the scraper clamp 600 to rotate relative to the adjusting rod 500 around the connection, thereby facilitating the subsequent adjustment of the angle between the adjusting rod 500 and the scraper clamp 600.
