Description

Technical Field

[0001] The invention relates to the technical field of oil drilling equipment, in particular to an oil drilling mud cooling device. Background Art

[0002] Mud is a semi-colloidal suspension formed by tiny particles of clay dispersed in water and mixed with water. In colloid chemistry, solid clay is called dispersed phase or solid phase, and water is called medium or liquid phase. If the solid phase is dispersed into molecules or ions, and there is no interface between the solid phase and the liquid phase, it is called a true solution, such as a solution of salt dissolved in water. If the particles dispersed in the liquid phase are composed of many molecules, although the particles are very small, there is an interface. Such a mixture is called a colloidal solution, and various commonly used glues belong to this category. If it is similar to a colloidal solution, but more than 40% of the solid particles are larger than 0.2μm (1μm=0.001mm), it is called a semi-colloid or suspension, and mud belongs to this semi-colloidal suspension. Mud is made by mixing clay with water. The use of mud can prevent hole collapse, suspend rock cuttings, and safely pass through the quicksand layer. Correct use of mud can ensure safe drilling. However, excessive use of mud will bring many difficulties to well washing and affect water output. Therefore, when using mud, it is necessary to thicken or dilute it at any time according to the different properties of the strata. The properties of mud usually refer to the mud's moisture, fineness (or residue), specific gravity (or density), fluidity and thixotropy, slurry absorption speed and other indicators. In ceramic production, the mud properties must be tested and controlled.

[0003] The existing device is a petroleum drilling mud cooling system (publication number CN115874964A), which includes a mud pool and an inner casing installed above the mud pool, the upper end of the inner casing is open, the outer casing is sleeved outside the inner casing, the lower end of the outer casing is open, and a material drop channel is formed between the outer casing and the inner casing; a feed barrel penetrating the outer casing is installed at the upper end of the outer casing, and a material drop mechanism for dropping the mud falling out of the feed barrel into the material drop channel and an air cooling mechanism for air cooling the mud dropped into the material channel are arranged in the inner casing directly below the feed barrel. The material throwing mechanism in the present application can throw the mud falling out of the barrel into the material dropping channel. Specifically, the gathered mud is scattered outward due to the centrifugal force and will naturally cool down during the scattering process. After the mud is scattered to the material dropping channel, the air cooling mechanism will blow the scattered mud again to further cool the mud, thereby quickly cooling the mud. The above device can improve the cooling efficiency of the mud scattered to the outside. However, due to its relatively closed structure, it is not convenient for heat dissipation, which will limit the cooling speed of the mud, and the injection port area is small, and the addition of raw materials is not flexible enough.

DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] like Figures 1 to 8 As shown, the present invention provides a petroleum drilling mud cooling device (hereinafter referred to as cooling device) including a hopper 5, an exhaust fan 2 and a base 1 which are sequentially installed from top to bottom. The base 1 is used to support the exhaust fan 2 and the hopper 5, the exhaust fan 2 is rotatably installed on the base 1, and the hopper 5 is installed on the top of the base 1 above the exhaust fan 2. The hopper 5 includes a support frame and a support layer 502 fixed on the support frame, and the support frame is used to support the support layer 502 to form a funnel-shaped cavity with a large top and a small bottom. When in use, the bottom opening of the hopper 5 is connected to the wellhead, and the mud thrown out of the well enters the hopper 5 through the opening at the bottom of the hopper 5. Since the top opening of the hopper 5 is relatively large, it is convenient for heat dissipation; the support layer 502 is made of waterproof and breathable material, for example, the support layer 502 can be made of waterproof and breathable fabrics made of polymer waterproof and breathable material (PTFE membrane) and cloth, or a waterproof and breathable membrane can be plated on the breathable fabric, so that the hopper 5 can carry mud and ensure that the mud does not leak out, so that the wind delivered by the exhaust fan 2 can be blown into the hopper 5 from the bottom, so as to facilitate air cooling from the lower surface of the mud. The exhaust fan 2 is set at the bottom of the hopper 5, so that the top of the hopper 5 is unobstructed, which is conducive to rapid heat dissipation; and the exhaust fan 2 is set at the bottom of the hopper and will not interfere with the feeding operation from the top of the hopper. In order to quickly and flexibly adjust the area of ​​the cooling device to collect the mud thrown out of the wellhead to the outside, the hopper 5 can be designed as a retractable and expandable structure, such as setting the support frame of the hopper 5 as a retractable and expandable structure, and adding an adjustment mechanism 7.

[0034] Specifically, the support frame includes a mounting plate 3, and an opening is provided on the mounting plate 3 that passes through the mounting plate 3 from top to bottom. A plurality of support rods 303 are hingedly connected around the mounting plate 3, and a support connection groove is fixedly installed on the upper end of the support rod 303. The support layer 502 is installed on the mounting plate 3 and the support rod 303 to enclose a bucket-shaped cavity.

[0035] The adjusting mechanism 7 includes an adjusting disk 601 and a lifting mechanism. A plurality of positioning adjusting rods 604 are hinged around the adjusting disk 601. The positioning adjusting rods 604 are rotatably connected to the supporting connection grooves on the supporting rods 303, so that the positioning adjusting rods 604 are hinged to the supporting rods 303. The lifting mechanism is used to drive the adjusting disk 601 to rise or fall. When the adjusting disk 601 rises, the positioning adjusting rods 604 pull the supporting rods 303 to rotate toward the inside of the hopper 5, and the hopper 5 gradually shrinks; when the adjusting disk 601 falls, the positioning adjusting rods 604 pull the supporting rods 303 to rotate toward the outside of the hopper 5, and the hopper 5 gradually expands until the internal space of the hopper 5 reaches an appropriate range.

[0036] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 The lifting mechanism includes an adjusting threaded tube 6 and an elevating threaded tube 602. The adjusting threaded tube 6 is vertically arranged, and the bottom of the adjusting threaded tube 6 is mounted on the top of the mounting plate 3; input holes are evenly opened around the elevating threaded tube 602, and these input holes are connected to the inner cavity of the elevating threaded tube 602, thereby forming a channel for the mud in the funnel-shaped cavity to enter the opening. An adjusting mounting hole is opened inside the adjusting disk 601, and the elevating threaded tube 602 is rotatably installed inside the adjusting mounting hole. The elevating threaded tube 602 can rotate relative to the adjusting disk 601 but cannot move up and down; the top of the adjusting threaded tube 6 passes through the adjusting mounting hole and the elevating threaded tube 602, and the elevating threaded tube 602 is sleeved on the outside of the adjusting threaded tube 6 and connected to the adjusting threaded tube 6 by threads. The upper end of the elevating threaded tube 602 is fixedly installed with an adjusting gear ring 605, and a motor mounting groove is opened at one corner of the adjusting disk 601, and an adjusting motor is embedded and installed inside the motor mounting groove, and a driving gear 606 is fixedly installed at the output end of the adjusting motor, and the driving gear 606 and the adjusting gear ring 605 are meshed with each other. When the adjusting motor starts, its output shaft drives the driving gear 606 to rotate, and the driving gear 606 drives the adjusting gear ring 605 to rotate. When the adjusting gear ring 605 rotates, it drives the lifting threaded tube 602 to rotate up or down along the adjusting threaded tube 6. When the adjusting threaded tube 6 rotates up or down, it drives the adjusting disk 601 to rise or fall along the adjusting threaded tube 6.

[0037] In other embodiments, the lifting mechanism includes a cylinder and a column, the column is vertically installed on the top of the mounting plate 3, the cylinder is fixed on the column, the piston rod of the cylinder is connected to the adjusting disk 601, and the adjusting disk 601 is driven to rise or fall by the extension and retraction of the piston rod.

[0038] In some embodiments, a plurality of expansion plates 4 may be hingedly connected around the mounting plate 3. The expansion plates 4 and the support rods 303 are alternately arranged, and there is only one expansion plate 4 between two adjacent support rods 303. An adapter plate 302 is fixedly installed at the center position of the upper end of each expansion plate 4, and each expansion plate 4 is provided with a mounting groove that runs through the left and right sides of the expansion plate 4. The supporting layer 502 includes a plurality of sub-support layers 503, and two sub-support layers 503 are arranged between two adjacent support rods 303. One side of one sub-support layer 503 of the two sub-support layers 503 is fixed to one of the two support rods 303, and the other side is fixed to a connecting rod 501; one side of the other sub-support layer 503 of the two sub-support layers 503 is fixed to the other support rod 303 of the two support rods 303, and the other side is fixed to the other connecting rod 501; the two connecting rods 501 are connected by one or more springs 304, see Fig. 9 , the two connecting rods 501 are connected by two springs 304, wherein the two ends of one spring 304 are respectively connected to the upper ends of the two connecting rods 501, and the two ends of the other spring 304 are respectively connected to the lower ends of the two connecting rods 501. The two connecting rods 501 are slidably installed in the installation groove of the expansion plate 4 located between the two support rods 303, and all the sub-support layers 503, the expansion plates 4 and the support rods 303 are together enclosed to form a hopper 5, and the expansion plate 4 is used to block the gap between two adjacent sub-support layers 503 to prevent the mud in the hopper 5 from flowing out of the gap. The number of the expansion plates 4, the support rods 303, the support layers 502 and the connecting rods 501 are related, the number of the expansion plates 4 is equal to the number of the support rods 303, the number of the sub-support layers 503 is twice the number of the support rods 303, and the number of the connecting rods 501 is equal to the number of the sub-support layers 503. As Figures 1 to 5 In the cooling device shown, four support rods 303 are hinged around the mounting plate 3, and an extension plate 4, two sub-support layers 503 and two support rods 303 are arranged between every two support rods 303, that is, a total of four extension plates 4, eight sub-support layers 503 and eight support rods 303.

[0039] When the hopper 5 is loaded with mud or when the hopper 5 is expanded, the distance between the two connecting rods 501 connected by the spring will increase under the pulling of the supporting layer 502, and the spring 304 can apply tension to the two connecting rods 501, which can effectively prevent the connection rods 501 from being separated from the expansion plate 4, thereby preventing the mud in the hopper 5 from flowing out to the outside. When the mud in the hopper 5 is reduced or the hopper 5 is contracted, the spring 304 applies tension to the two connecting rods 501, and the two connecting rods 501 are close to each other and the distance between them becomes smaller, so that the supporting layer 502 is in a tight state, preventing the supporting layer 502 from being relaxed, thereby achieving the effect of improving the restraint of the breathable waterproof cloth on the mud.

[0040] There are also multiple expansion adjustment rods 603 hinged around the adjustment disk 601. The expansion adjustment rods 603 and the positioning adjustment rods 604 are arranged alternately. The expansion adjustment rods 603 and the adapter grooves on the expansion plate 4 form a rotational connection, so that the expansion adjustment rods 603 and the expansion plate 4 are hinged to facilitate pushing the expansion plate 4 to expand and position.

[0041] In some embodiments, the plurality of support rods 303 and the plurality of expansion boards 4 are not directly hinged to the mounting plate 3, but connection grooves are provided around the mounting plate 3, and the connection frame 301 is clamped in the connection grooves, and then the plurality of support rods 303 and the plurality of expansion boards 4 are hinged to the connection frame 301, thereby indirectly forming a hinge connection with the mounting plate 3. The plurality of expansion boards 4 and the plurality of support rods 303 are radially distributed around the connection frame 301. In this way, after the support rods 303, the expansion boards 4 or the connection frame 301 are worn due to rotation, they can be easily disassembled and replaced without disassembling the mounting plate 3.

[0042] In order to facilitate the transportation of the mud in the hopper 5 to the outside, it is preferred to set the hopper 5 as a structure that can be unfolded in reverse, so that when the adjusting disk 601 descends, it can drive the hinge point of the positioning adjustment rod 604 and the support rod 303 to descend to below the hinge point of the corresponding support rod 303 and the mounting plate 3, thereby allowing the hopper 5 to unfold in reverse. For example, in a specific embodiment, one end of the positioning adjustment rod 604 is hinged to the adjustment disk 601 at a first hinge point, the other end of the positioning adjustment rod 604 is hinged to the support rod 303 at a second hinge point, and the support rod 303 is hinged to the connecting frame 301 at a third hinge point; the distance between the first hinge point and the second hinge point is greater than the distance between the second hinge point and the third hinge point; as the adjustment disk 601 continues to descend, the positioning adjustment rod 604 continues to push the support rod 303 to rotate downward around its hinge point with the connecting frame 301 (i.e., the third hinge point) until the hinge point between the positioning adjustment rod 604 and the support rod 303 (i.e., the second hinge point) drops below the hinge point between the support rod 303 and the connecting frame 301, and the hopper 5 unfolds in the reverse direction. One end of the extension adjustment rod 603 is hinged to the adjustment disk 601 at the fourth hinge point, the other end of the extension adjustment rod 603 is hinged to the extension plate 4 at the fifth hinge point, and the extension plate 4 is hinged to the connecting frame 301 at the sixth hinge point; the distance between the fourth hinge point and the fifth hinge point is greater than the distance between the fifth hinge point and the sixth hinge point; as the adjustment disk 601 continues to descend, the extension adjustment rod 603 continues to push the extension plate 4 to rotate downward around the hinge point between it and the connecting frame 301 (i.e., the sixth hinge point) until the hinge point between the extension adjustment rod 603 and the extension plate 4 (i.e., the fifth hinge point) drops below the hinge point between the extension plate 4 and the connecting frame 301; the hopper 5 unfolds in the reverse direction.

[0043] When the mud needs to be transported to the outside, the user turns on the adjustment motor to push the adjustment disk 601 downward until the support rod 303 and the expansion plate 4 are pushed to drive the support layer 502 to expand in the opposite direction. The mud inside the hopper 5 will flow out to the outside along the upper surface of the support layer 502 and the expansion plate 4, making it convenient for the user to collect the mud.

[0044] See also Figure 7The base 1 includes a support tube 101, and the hopper 5 is fixedly installed on the top of the support tube 101 through the mounting plate 3. The funnel-shaped cavity of the hopper 5 is connected to the support tube 101 through the opening on the mounting plate 3, and the support tube 101 is used to connect the wellhead. A plurality of stabilizing rods 102 are evenly fixedly installed on the outside of the support tube 101 to support the support tube 101 on all sides and improve the stability of the support tube 101. A support ring 103 is fixedly installed on the outside of the stabilizing rod 102, and a plurality of supporting threaded tubes 104 are fixedly installed on the lower surface of the supporting ring 103. The supporting threaded tube 104 is used to increase the distance between the exhaust fan 2 and the ground, so as to facilitate the operation of the exhaust fan 2. Preferably, the plurality of supporting threaded tubes 104 are evenly distributed along the circumference of the uniform supporting ring 103. An adjusting bolt 105 is installed inside the supporting threaded tube 104, and the adjusting bolt 105 is connected to the supporting threaded tube 104 by a thread. The upper part of the adjusting bolt 105 is provided with a positioning nut 106, and the positioning nut 106 and the adjusting bolt 105 are connected by threads. The lower end of the adjusting bolt 105 is provided with a positioning cone 107, so as to stably install and fix the device in an appropriate position. The adjusting bolt 105 in the supporting threaded tube 104 is rotated to rotate and descend, and the adjusting bolt 105 drives the positioning cone 107 to move downward until the positioning cone 107 and the ground are closely fitted to each other; then the positioning nut 106 is rotated to rotate and rise around the adjusting bolt 105 until the upper surface of the positioning nut 106 and the lower surface of the supporting threaded tube 104 are closely fitted to each other, and the positioning nut 106 can prevent the adjusting bolt 105 from rotating and shifting due to vibration.

[0045] See also Figure 8 The exhaust fan 2 includes a driving ring 201, a driving groove is provided on the outer side of the upper end of the support tube 101, and the driving ring 201 is rotatably connected in the driving groove; a plurality of blades 202 are fixedly installed on the outer side of the driving ring 201, and a protective ring 203 is fixedly installed on the outer side of the blades 202. The provision of the protective ring 203 can effectively prevent the three blades from scratching the operator. Preferably, the plurality of blades 202 are evenly distributed along the circumference of the driving ring 201. A driving gear ring 204 is fixedly installed on the outer side of the lower end of the driving ring 201, a driving motor 205 is embedded and installed on one side of the driving groove, and a power gear 206 is fixedly installed on the output end of the driving motor 205, and the power gear 206 and the driving gear ring 204 are meshed with each other. The airflow below the hopper 5 is blown from the outside to the lower surface of the supporting layer 502 through the blades 202, and the lower end of the mud falling into the hopper 5 is blown to accelerate the loss of its heat.

[0046] In some embodiments, see Figure 1 , Figure 6A feeding mechanism is also provided above the hopper 5, and the feeding mechanism includes an output pipe 701, and a plurality of output holes are evenly provided on the lower surface of the output pipe 701, and a pressure nozzle 8 is embedded and installed inside each output hole. An input hole is provided on one side of the output pipe 701, and an input connector 702 is fixedly installed inside the input hole, and an input pipe 703 is installed inside the input connector 702. In order to make the feeding uniform, preferably, the output pipe 701 is an annular pipe and is fixedly installed on the lower surface of the regulating disk 601. The user can selectively blow or spray the external coolant, cooling gas, mud raw material, and liquid auxiliary raw material on the upper end of the mud through the feeding mechanism as needed to increase the heat dissipation area and heat dissipation effect of the mud raw material.

[0047] When using the cooling device of the present invention to cool the mud thrown out of the oil well, first move the cooling device to an appropriate position, adjust the position of the base 1, make the positions of the support pipe 101 and the oil well head correspond to each other, and the oil well head is connected to the support pipe 101. The mud thrown out of the oil well head overflows into the hopper 5 through the support pipe 101, and the exhaust fan 2 is turned on to blow the airflow under the hopper 5 to the lower surface of the support layer 502, and blow the lower end of the mud falling into the hopper 5 to accelerate the loss of heat of the mud. The input pipe 703 is connected to the external coolant or other liquid auxiliary materials as needed, and the mud is sprayed from the upper end of the mud through the pressure nozzle 8 to cool the mud. When the amount of mud gradually increases or the range of mud thrown out of the oil well mouth expands, the regulating motor can be turned on to push the regulating disk 601 downward, and the regulating disk 601 pushes the support rod 303 and the expansion plate 4 to rotate outward, thereby driving the support layer 502 to gradually expand outward, so that the hopper 5 is expanded, and the area of ​​the cooling device for collecting the mud thrown out to the outside and the collection and processing space of the mud are rapidly expanded. When the mud needs to be transported to the outside, the regulating motor is turned on to push the regulating disk 601 to continue to move downward until the support rod 303 and the expansion plate 4 are pushed to drive the support layer 502 to expand in the opposite direction, and the mud inside the hopper 5 will flow out to the outside along the upper surface of the support layer 502 and the expansion plate 4, which is convenient for users to collect the mud.
