Description

Technical Field

[0001] The invention relates to the technical field of oil drilling equipment, and in particular to a solid control system and a quick-moving and quick-installing device thereof. Background Art

[0002] Drilling costs mainly include two aspects: one is the production cost directly generated during the drilling process; the other is the necessary production cost generated for auxiliary production before and after the drilling process, that is, the shutdown cost caused by relocation and the transportation cost during relocation; therefore, the ability to quickly disassemble, move, reorganize and install can greatly reduce drilling costs.

[0003] There are already integrated fast-moving drilling rigs on the market, but there are still many unresolved pain points for the solids control system. 1. With the increase in drilling depth, the number of purification and treatment equipment and mud tanks in the solids control system increases. The floor space occupied by the well site exceeds that of the main machine, and more transportation vehicles are required; 2. Users require complex purification processes, many pipelines connecting the tanks, and a long time for disassembly and assembly; 3. When the solids control system is transported to a new well site for installation, the pipelines connecting the tanks require that the misalignment of the ends cannot be too large, generally around 50 mm. For tanks with a length of more than 10 meters, if you want to align the pipe mouth for installation, you often need to draw lines and reverse to align multiple times, which is very difficult; 4. The installation of the solids control system often requires the cooperation of cranes and aerial vehicles, which is costly and has great safety hazards.

[0004] The application number is 201220377930.5, which is a trailer device for facilitating the transportation of a mud pump. The invention discloses a front frame mainly composed of a left front frame of a longitudinal beam, a right front frame of a longitudinal beam, and front ear seats respectively connected to the left front frame of the longitudinal beam and the right front frame of the longitudinal beam, a traction device, a positioning device, and a rear frame respectively movably connected to the front frame, a load-bearing axle connected to the bottom of the rear frame, and wheels installed at both ends of the load-bearing axle. The invention discloses a modular structure for convenient transportation, but the invention still cannot effectively solve the problem of rapid disassembly and assembly of pipelines between tanks.

[0039] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0040] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0042] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] like Figure 1 and Figure 2 As shown, the present invention provides a solid control system, including multiple tank bodies, and the spatial layout of the multiple tank bodies in the well site can be multiple rows and columns, that is, tank bodies can be arranged at adjacent front, back, left and right positions of a single tank body, and, in the present disclosure, the tank body can be a mud tank; in addition, at least two tank bodies can form a transport module, when the solid control system needs to be moved, modular transportation between the tank bodies of the solid control system can be realized, and the moving efficiency can be improved. Compared with the transportation of a single tank body, the transportation cost is reduced. The following is an explanation using two tank bodies forming a transport module.

[0044] In this embodiment, two tank bodies 10 are transported at one time during the moving process of the solid control system. Therefore, in the process of disassembling the pipeline interface, the pipeline interface between the two tank bodies 10 that are transported at one time does not need to be disassembled. Only the interface of the tank body 10 between different transport modules needs to be disassembled, which reduces the number of pipelines that need to be disassembled, effectively reduces the workload, and improves the moving efficiency.

[0045] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, usually the pipelines with a diameter greater than or equal to DN150 between the two-stage functional treatment tanks 10 include: a sewage pipeline (diameter of about DN200-DN300), a suction pipeline (diameter of about DN200-DN300), and aqueduct connecting pipeline (diameter of about DN250-DN400). In addition, due to different placement positions, there may also be pipelines such as degassing, mud removal, sand removal, centrifugal suction pipe (diameter of about DN200) and discharge pipe (diameter of about DN150-DN200).

[0046] In addition to the end surface connection positions between the two-stage functional processing tank bodies 10, there are also left and right connection positions. In order to improve the efficiency of disassembly and assembly of pipelines between the tank bodies 10, the interfaces that need to be disassembled and assembled between the upper and lower tank bodies 10 are connected by flexible joints 20.

[0047] Specifically, in this embodiment, the top of the previous treatment tank 201 and the next treatment tank 202 are connected by a trough connecting pipe 210, the previous treatment tank 201 is provided with a sewage connecting pipe 230, and the next treatment tank 202 is provided with a suction connecting pipe 212, wherein the sewage connecting pipe 230 and the suction connecting pipe 212 are connected by a flexible joint 20. In order to facilitate disassembly and assembly and reduce the work of the staff manually swinging a sledgehammer during disassembly and assembly, pneumatic tube unions 220 are provided between both ends of the flexible joint 20 and the pipeline, and the flexible joint 20 is connected to the pipeline through the pneumatic tube union 220.

[0048] In the present disclosure, the flexible joint 20 includes a flexible body 21, and the flexible body 21 includes at least one sphere. Fig. 9 As shown, the flexible body 21 includes a sphere, and the flexible joint 20 is a single-ball flexible joint. Connecting pipes 22 are installed at both ends of the flexible body 21. The connecting pipe 22 is connected to the pipeline on the tank body 10. Specifically, the pipeline includes a push-in pipe 23 and a pull-out pipe 24. In this embodiment, the push-in pipe 23 is connected to the previous treatment tank 201, and the pull-out pipe 24 is connected to the next treatment tank 202. In other embodiments, the push-in pipe 23 can be connected to the next treatment tank 202, and the pull-out pipe 24 can be connected to the previous treatment tank 201. It can be selected according to actual needs. In other embodiments, the flexible body 21 includes two spheres, and the flexible joint 20 is a double-ball flexible joint. Since the aqueduct connecting pipe 210 has a large diameter (generally DN300), a double-ball flexible joint can be used. The deflection angle allowed by the double-ball flexible joint can reach 30°.

[0049] Furthermore, a dragging handle 25 is provided on the connecting tube 22 connected to the pull-out tube 24, which facilitates pulling the connecting tube 22 out of the pull-out tube 24. At the same time, a fixing hook 26 is provided on the connecting tube 22, and a fixing chain 27 cooperating with the fixing hook 26 is provided on the push-in tube 23. The fixing chain 27 is hung on the fixing hook 26 to fix the connecting tube 22 to the pull-in tube 23 to prevent the connecting tube 22 from being pushed out due to excessive pressure in the pipeline.

[0050] like Fig. 9 , Fig.10 and Fig.11As shown, during the use of the flexible joint 20, the connecting tube 22 is respectively inserted into the push-in tube 23 and the pull-out tube 24 to achieve communication between the tank bodies 10. Due to the presence of the flexible body 21, during use, a certain deviation can be made between the axes of the push-in tube 23 and the pull-out tube 24. When disassembly is required, the connecting tube 22 is pulled out of the pull-out tube 24 using the drag handle 25. Correspondingly, the connecting tube 22 docked with the push-in tube 23 is extended into the push-in tube 23. Then the fixing chain 27 is hung on the fixing hook 26. At this time, the pipelines between the two tank bodies 10 are separated. After all the pipelines on different transport modules are separated, the two tank bodies 10 are transported away using the transport module.

[0051] like Fig.12 As shown, in order to ensure sealing and facilitate docking, a pneumatic union 220 is provided between the connecting tube 22 and the pipeline, wherein the pneumatic union 220 includes a union body 30, and an airbag 31 is provided on the inner circle of the union body 30. The inner circle of the airbag 31 contacts the side of the connecting tube 22. When disassembling, the airbag 31 is deflated to release the sealed connection. At this time, the connecting tube 22 can be conveniently moved. During use, the airbag 31 is inflated to form a sealing effect, thereby realizing the material transportation between the tank bodies 10.

[0052] In this embodiment, the pneumatic union 220 allows a deviation of 7° (the radial allowable deviation range of a one-meter-long steel pipe can reach 100mm), and the flexible joint 20 can allow axial displacement and lateral displacement within a certain range. When superimposed with the pneumatic union 220, the axial displacement can be sealed within at least 200mm without leakage, and the lateral displacement can be sealed within 150mm without leakage. This design will greatly reduce the back-and-forth operations of multiple alignment and reversing operations, saving time.

[0053] like Fig.13 and Fig.14 As shown, for straight-connected pipelines without angular deviation, in order to improve installation efficiency, the solid control system also includes a pipeline translation docking device, the pipeline translation device includes a cylinder 40 and a docking tube 42, one end of the cylinder 40 is connected to the pipeline, and the other end of the cylinder 40 is connected to the docking tube 42, one end of the docking tube 42 is connected to the pipeline connected to the cylinder 40, and the other end of the docking tube 42 can be connected to or disconnected from another pipeline under the action of the cylinder 40.

[0054] In this embodiment, the pipe connected to the cylinder 40 and connected to one end of the butt-joint pipe 42 is the push-in pipe 23, and the other pipe connected to or disconnected from the other end of the butt-joint pipe 42 is the pull-out pipe 24. The push-in pipe 23 and the pull-out pipe 24 are connected through the butt-joint pipe 42. In some embodiments, a plurality of cylinders 40 may be installed on the push-in pipe 23, and the plurality of cylinders 40 are distributed along the circumference of the push-in pipe 23. The working end of the cylinder 40 is connected to the butt-joint pipe 42 through the fixing plate 41. When disassembling, the cylinder 40 only needs to be shortened to move the butt-joint pipe 42 out of the pull-out pipe 24 and into the push-in pipe 23. When installing, the cylinder 40 only needs to be extended to insert the butt-joint pipe 42 into the pull-out pipe 24 to achieve the connection between the tank bodies 10. Generally, this method is adopted for straight connection pipelines without angle deviation such as wellhead overflow pipes; at the same time, a positioning guide pipe 43 is also provided on the pipeline to ensure that the cylinder 40 moves linearly.

[0055] A fast moving and fast loading device for a solid control system, such as Figure 1-14 As shown, it includes the solid control system as described above, wherein a rear frame 12 is installed at one end of the tank body 10 in the transport module, and the other end is connected to the trailer 14 through a gooseneck 13, wherein in order to make the trailer more stable during transportation, the two rear frames 12 are connected by a connecting bracket 15.

[0056] Specifically, the transport module also includes a braking system, an electrical system, a suspension system, an axle, tires and rims. The tank body 10 can play a connecting role while being transported. The tank body 10 towed on the transport module is connected to the gooseneck 13 and the rear frame 12 by a pin shaft. After the first installation, there is no need to hammer the installation pin shaft again.

[0057] The rear frame 12 and the gooseneck 13 are both equipped with lifting cylinders 11, and the gooseneck 13 is provided with a hydraulic station 110 for providing power to the lifting cylinders 11. Specifically, in this embodiment, each transport module has only four lifting cylinders 11 distributed in a matrix.

[0058] In this embodiment, by using the lifting cylinder 11, there is no need for a crane to unload and install the vehicle, which reduces costs and improves moving efficiency. Four lifting cylinders 11 are equipped to steadily lift the tank body 10 to a suitable height, and a saddle is used to connect it to the trailer 14. After the lifting cylinder 11 is retracted, the moving and transportation can be carried out.

[0059] It should be understood that the above description of the specific embodiments of the present invention is only for illustrating the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, but the present invention is not limited to the above specific implementation methods.
