Description

Technical Field

[0001] This invention belongs to the field of intelligent treatment technology for ferromagnetic substances in drilling mud, specifically relating to an intelligent device for removing ferromagnetic substances from drilling mud and its usage method. Background Technology

[0002] Drilling mud plays an irreplaceable role in the drilling process, including cleaning the wellbore, suspending and carrying rock cuttings, keeping the wellbore clean, balancing formation pressure, stabilizing the wellbore, preventing well collapse, blowouts, and lost circulation, transmitting water power to help the drill bit break rocks, transmitting power to downhole power tools, and cooling the drill bit and tools. However, due to the presence of metals such as iron, nickel, and cobalt in the formation, as well as drill bit wear, a large amount of fine ferromagnetic substances are generated in the drilling mud. These fine ferromagnetic substances continuously dissolve into the mud, contaminating it, increasing friction, consuming energy, accelerating drill bit wear, and reducing drill bit life. At the same time, these ferromagnetic substances can also affect the measurement accuracy of downhole magnetic monitoring instruments, causing them to malfunction and resulting in serious losses to the drilling process.

[0003] Currently, through continuous research and development, China has made a series of attempts in drilling mud demagnetization technology and equipment. These attempts involve strong magnetic circulation adsorption, centrifugal removal, replacement of drilling fluid materials, and even multiple replacements of drilling fluid. This not only wastes a lot of time but also consumes a large amount of drilling fluid and materials, which seriously restricts the progress of drilling and development.

[0004] Therefore, it is urgent to study the sources of ferromagnetic substances and efficient automated reduction equipment. On the one hand, we need to identify the sources of ferromagnetic substances and take measures to limit them at the source; on the other hand, we need to use automated equipment to efficiently reduce ferromagnetic substances in drilling fluid, so as to reduce losses and achieve faster drilling.

[0073] Example 5

[0074] like Figures 1 to 4 As shown in the figure, this embodiment provides an intelligent ferromagnetic material removal device for drilling mud, including an intelligent control panel 1, a drive motor 2, a right magnetic rod assembly mounting plate 3, a right guide column 4, a right magnetic rod assembly 5, a right scraper 6, a frame 7, a left scraper 8, a left magnetic rod assembly mounting plate 9, a left guide column 10, a left magnetic rod assembly 11, a nut screw 12, a movable slag hopper roller frame 13, a movable slag hopper 14, a movable slag hopper drive chain 15, a movable slag hopper drive motor 16, a movable slag hopper chain 17, a movable slag hopper gear 18, a movable slag hopper pulley 19, a movable slag hopper drive gear 20, and a movable slag hopper transmission guide column 21, wherein:

[0075] The left and right magnetic rod groups, the magnetic rod group mounting plate, the guide posts, the mud scraper, and the moving slag receiving hopper guide posts are symmetrical structures. They are divided into left and right structures with the intelligent control panel as the center of symmetry. The two magnetic rod groups, the guide posts, the mud scraper, and the moving slag receiving hopper guide posts have the same structure.

[0076] Both the left magnetic rod group 11 and the right magnetic rod group 5 are composed of 14 cylindrical magnetic rods, which are respectively installed on the left magnetic rod mounting plate 9 and the right magnetic rod mounting plate 2. The length of the magnetic rod group is customized according to the depth of the drilling mud ditch. The magnetic rod group uses, but is not limited to, strong magnetic materials such as neodymium iron boron, and the surface of the magnetic rod is treated with, but is not limited to, stainless steel of SUS304 material.

[0077] They are arranged in a "pin" shape, that is, 14 magnetic rods are arranged in three rows, and the magnetic rods in adjacent rows are staggered. The spacing ensures the range that the adsorption force can reach while forcing the mud to flow through the magnetic rods in an "S" shape.

[0078] The openings on the mud scraper can be changed according to the number of magnetic rods. The openings are made of O-shaped lip rubber to ensure the mud scraping effect.

[0079] The number of magnetic rods on the magnetic rod mounting plate can be adjusted by the magnetic rod group through a combined disassembly method to adapt to the on-site working conditions.

[0080] The left magnetic rod group 11 and the right magnetic rod group 5 adopt independent structures and can be controlled by the intelligent control panel 1 to work independently according to the on-site requirements.

[0081] The intelligent device for removing ferromagnetic substances from drilling mud is arranged above the mud ditch and consists of 2 sets of magnetic rod groups on the left and right. The 2 sets of magnetic rod groups do not interfere with each other and cooperate. When working normally, the left magnetic rod group 11 and the right magnetic rod group 5 are both on the nut screw rod 12 and move downward along the left guide post 10 and the right guide post 4 into the mud respectively.

[0082] The cleaning of the magnetic rod group can be carried out in groups. When the left magnetic rod group 11 is working normally, the right magnetic rod group 5 can start the cleaning operation. After the right magnetic rod group 5 is cleaned, the right magnetic rod group 5 can be lowered to start removing ferromagnetic substances, and the left magnetic rod group 11 can be lifted for cleaning work. Or the left and right magnetic rod groups can be put into the drilling mud simultaneously for removing ferromagnetic substances, so as to realize the continuity of the ferromagnetic substance removal operation.

[0083] Embodiment 6

[0084] A method for removing magnetic substances from mud by the mud iron chip removing device provided in this embodiment includes the following steps:

[0085] Step 1. During normal operation, the drilling mud will be discharged through the mud channel after passing through the solids control system from the wellbore. At this time, the left magnetic rod group 11 and the right magnetic rod group 5 are lowered along the guide column so that the drilling mud flows evenly through the magnetic rod group in the working state, and the ferromagnetic substances in the mud are adsorbed on the surface of the magnetic rod group.

[0086] Step 2. When the working time is up, one set of magnetic rods 5 (11) is lifted, and the second set of magnetic rods 11 (5) continues to adsorb. At this time, the rollers on the roller frame 13 of the moving slag hopper are used to initially scrape off the mud on the set of magnetic rods 5 (11). Then the moving slag hopper drive motor 16 is started, which drives the moving slag hopper drive chain 15 to move the moving slag hopper gear 20. The moving slag hopper gear 20 drives another moving slag hopper gear 20, which in turn drives the moving slag hopper chain 17 to move. The moving slag hopper chain 17 drives the moving slag hopper 14 to move below the first set of magnetic rods 5 (11) and enter the waiting state.

[0087] Step 3. Once the mobile slag receiving hopper 14 is ready, the scraper 6 (8) will scrape the magnetic rod assembly 5 (11) downwards to scrape the mud on the magnetic rod assembly into the mobile slag receiving hopper 14.

[0088] Step 4. After completing the sludge scraping operation of a set of magnetic rods 5 (11), move the slag receiving hopper 14 away, return it to the middle position, and put the first set of magnetic rods 5 (11) into the mud ditch to continue the adsorption work.

[0089] Step 5. After the timer for the second set of magnetic rods 11(5) expires, lift the second set of magnetic rods 11(5) and the first set of magnetic rods 5(11) continues to adsorb. At this time, the slag receiving hopper 14 will move to the bottom of the second set of magnetic rods 11(5) and enter the waiting state.

[0090] Step 6. When the mobile slag receiving hopper 14 is ready, the scraper 8 (6) will scrape the magnetic rod assembly 11 (5) downwards, scraping the mud on the magnetic rod assembly 11 (5) into the mobile slag receiving hopper. After the scraping is completed, the mobile slag receiving hopper drive motor 16 will drive the mobile slag receiving hopper back to the middle position.

[0091] Step 7. The two sets of magnetic rods work alternately, repeating processes 1 to 6, to achieve fully automatic operation of the entire device;

[0092] Step 8. When it is necessary to clean a particular set of magnetic rods, the set of magnetic rods can be lifted separately and cleaned.

[0093] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
