Description

Technical Field

[0001] This invention relates to the field of drilling mud resource recovery and treatment equipment, specifically a mobile drilling mud resource recovery and treatment device and method. Background Technology

[0002] As the world's primary fossil fuel, petroleum still occupies a crucial position in the global energy structure. Drilling technology, as the technical method for drilling oil and gas wells during oil and gas exploration and extraction, is widely used. In drilling operations, drilling fluid is an indispensable substance for ensuring the normal operation of the well, playing roles such as balancing formation pressure, protecting the wellbore, cleaning the well bottom, and transmitting power. Water-based drilling fluids account for more than 60% of the drilling fluid system, and with the promotion of environmental regulations, the proportion of water-based drilling fluids used will continue to increase. Water-based drilling mud is the main waste generated in oil drilling operations, and its components include water-based drilling fluid, drill cuttings generated during the drilling process, and waste liquids generated during on-site operations. Waste drilling mud is generated during oil and gas field exploration and development operations. It includes cleaning fluids from various operating equipment, fluids used to flush oil and gas wells, and mud- and oil-containing fluids generated by rainwater runoff from the well site. Compared to traditional engineering drilling mud, it contains various high-molecular polymer treatment agents such as filtration loss reducers and inhibitors, and also contains drill cuttings, heavy metal ions, and oil phases, characterized by high suspended solids concentration, high color, and extremely complex composition. In recent years, the environmental issues of waste water-based drilling mud have gradually attracted widespread attention. Reducing the discharge of waste drilling mud, harmlessly treating waste drilling mud, and recovering and recycling useful drilling fluid components from waste drilling mud for resource utilization have become increasingly important.

[0003] However, traditional drilling mud resource recovery and treatment equipment has the following obvious drawbacks when in use: First, traditional treatment methods are decentralized and unintegrated, requiring multiple fixed stations and equipment to work in succession, resulting in low efficiency and large land area requirements; second, traditional treatment methods are not effective in dewatering and drying mud with high water content, and conventional methods are unable to effectively destroy its colloidal stable structure and remove internal bound water; finally, traditional methods are also unable to efficiently and simultaneously remove suspended solids and light pollutants such as oil from the mud, affecting subsequent water reuse and mud resource utilization. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile drilling mud resource recovery and treatment device and method to solve the problems mentioned in the background art.

The anode blocks are arranged around the side wall of the stirring chamber. The filter screen is sleeved on the outside of the main shaft, and one end of the filter screen is inserted into the water collection tank.

[0017] Preferably, the post-treatment tank is provided with a purification tank and an adjustment tank. A transfer pump is provided in the water collection tank. The transfer pump is used to pump the supernatant in the water collection tank into the purification tank.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-15 The present invention provides a technical solution:

[0046] A mobile drilling mud resource recovery and treatment device, as shown in the instruction manual. Figure 1 As shown, it includes:

[0047] Mobile platform 1 is equipped with a towing hook and can be towed by a tractor. Mobile platform 1 is equipped with a mud dewatering tank 2. The mud dewatering tank 2 has a crushing chamber 201 and a mixing chamber 202. The mixing chamber 202 is connected to a post-processing box.

[0048] The pretreatment unit is located in the crushing chamber 201. The pretreatment unit includes a primary screening mechanism and a multi-stage crushing mechanism. The primary screening mechanism is used to screen the high water content water-based drilling mud, and the multi-stage crushing mechanism is used to crush the high water content water-based drilling mud in multiple stages. The crushed high water content water-based drilling mud will enter the mixing chamber 202.

[0049] The dewatering unit includes a spraying mechanism and an electroosmosis mechanism. The spraying mechanism is used to spray the desiccant and flocculant into the mixing chamber 202 in sequence, and the electroosmosis mechanism is used to further dewater the mud through electroosmosis.

[0050] The suspended solids removal unit includes a vortex air flotation mechanism, a scraping mechanism, and a collection box 4. The vortex air flotation mechanism is used to separate suspended solids and oil in water-based drilling mud, and the scraping mechanism is used to scrape off the suspended solids and oil and input them into the collection box 4.

[0051] The post-processing unit includes a stirring mechanism 2 and a pumping mechanism. The stirring mechanism 2 is used to stir the mixture in the post-processing tank, and the pumping mechanism is used to input the low water content mud in the stirring chamber 202 into the fluidized solidified soil preparation tank 17. The fluidized solidified soil preparation tank 17 is used for fluidized solidified soil preparation.

[0052] The primary screening mechanism includes screen 5, screen 6, and screen 7. The multi-stage crushing mechanism includes a primary crushing disc 8 and a secondary crushing disc 9. Screen 5, primary crushing disc 8, screen 6, secondary crushing disc 9, and screen 7 are arranged sequentially along the flow direction of high water content water-based drilling mud. The aperture of screen 5, screen 6, and screen 7 decreases sequentially, thereby achieving step-by-step screening of the mud particles. The design of the multi-stage crushing mechanism reduces the volume of mud particles and increases their surface area, which is more conducive to the full reaction with flocculants. It is also conducive to the full reaction with the solidifying agent added after dewatering, thus improving the solidification efficiency. Furthermore, the large particle size in the crushed mud can meet the requirements for the preparation of fluidized solidified soil.

[0053] The spraying mechanism includes a spray head 10, which is arranged around the inner wall of the mixing chamber 202. The spray head 10 is used to spray the de-gelling agent or flocculant into the mixing chamber 202. In this embodiment, a bio-enzyme de-gelling agent is selected when de-gelling the drilling mud. If there is a further need for delayed de-gelling, a capsule oxidation de-gelling agent can be considered. However, special treatment should be given to the core oxidant type and capsule material to reduce the secondary pollution problem of the oxidant and capsule. In this embodiment, non-ionic polyacrylamide (NPAM) or anionic polyacrylamide (APAM) is selected as the flocculant when flocculating the drilling mud because they are organic macromolecules. The impact of the residue on the drilling fluid performance and the strength of the solidified soil is much smaller than that of the cationic monomers or metal ions introduced when using other flocculants.

[0054] The vortex-type air flotation mechanism includes a stirring motor 11, a main shaft 12, stirring blades 13, an aerator 14, an aeration main pipe 15, and an aeration sub-pipe 16. The stirring motor 11 drives the main shaft 12 to rotate. The stirring motor 11 is connected to the main shaft 12 via a reducer. Connecting the stirring motor 11 and the main shaft 12 via the reducer increases the output torque and facilitates the installation of the aerator 14. Several stirring blades 13 are arranged around the main shaft 12. In this embodiment, the stirring blades 13... A displacement limiter (not shown in the attached diagram) is connected, allowing the stirring blades 13 to move up and down within the range of the displacement limiter to enhance the mixing effect. An aerator 14 is mounted on the main shaft 12 and is powered by an external power source. The aerator 14 is connected to several aeration tubes 16 via an aeration main pipe 15. The aeration main pipe 15 passes through the inner cavity of the main shaft 12, and the aeration tubes 16 are located inside the stirring blades 13. Each aeration tube 16 has several air outlets.

[0055] The scraping mechanism includes a scraper 18, a conveying pipe 19, a first docking valve 20, a second docking valve 21, a conveying ring 22, and a cleaning pump 23. The scraper 18 is mounted on the main shaft 12, and the conveying pipe 19 is mounted on the scraper 18. One end of the conveying pipe 19 is equipped with a first docking valve 20, and several second docking valves 21 are arranged around the conveying ring 22. One end of the second docking valve 21 is located on the inner wall of the stirring chamber 202. When the first docking valve 20 and the second docking valve 21 are docked together, the conveying pipe 19 and the conveying ring 22 are connected to each other. The cleaning pump 23 is used to generate negative pressure in the conveying ring 22. At this time, suspended solids and oil will be sucked into the conveying ring 22 and discharged from the main unit. The cleaning pump 23 is connected to the collection box 4.

[0056] The post-treatment box is located at the bottom of the sludge dewatering tank 2. The post-treatment box has a water collection tank 301. The electro-osmosis mechanism includes a cathode block 24, an anode block 25, and a filter screen 26. Several cathode blocks 24 are arranged around the main shaft 12. The anode blocks 25 are arranged around the side wall of the mixing chamber 202. The filter screen 26 is sleeved on the outside of the main shaft 12. One end of the filter screen 26 is inserted into the water collection tank 301. When the cathode block 24 and the anode block 25 are energized, an electric field is formed between the cathode block 24 and the anode block 25. The electric field causes the cations (such as hydrogen ions and sodium ions) in the double electric layer of the sludge particles to carry water molecules toward the cathode. The water molecules penetrate the filter screen 26 near the cathode and are discharged into the water collection tank 301.

[0057] The post-treatment tank is equipped with a purification tank 302 and an adjustment tank 303. A transfer pump 27 is installed in the water collection tank 301. The transfer pump 27 is used to pump the supernatant in the water collection tank 301 into the purification tank 302. In this embodiment, the purification tank 302 is equipped with a multi-media filter, a microfilter, and an oxidation adsorption chamber. The multi-media filter, microfilter, and oxidation adsorption chamber are used to further remove impurities not removed by the vortex air flotation mechanism. The adjustment tank 303 is used to adjust and re-mix the treated liquid in the purification tank 302. In this embodiment, the multi-media filter is made of filter media such as quartz sand and walnut shells and is used to filter particulate matter. The microfilter is a core filter (or bag filter). The oxidation adsorption chamber uses ozone as a strong oxidant. The main consideration for choosing ozone as an oxidant is the initial intention of resource utilization of useful components in drilling waste fluid. While purifying, it retains the useful drilling fluid components in the filter fluid to the maximum extent. Ozone has high oxidizing power, but the reaction is selective. It preferentially reacts with small-molecule organic matter, surfactants, biopolymers, and bacteria, while causing relatively little damage to higher molecular weight synthetic polymers (such as partially hydrolyzed polyacrylamide HPAM, PAC, etc.). Furthermore, by controlling the ozone dosage and reaction time, pollutants that cause increased COD can be primarily removed while retaining the main treatment agent. Compared to indiscriminate strong oxidants (such as sodium hypochlorite), ozone causes minimal damage to useful polymers.

[0058] The second stirring mechanism is set in the regulating tank 303, which is used to re-mix the clear liquid to prepare drilling fluid again. The second stirring mechanism includes a second stirring motor 28 and a stirring rod 29. The stirring rod 29 is set in the regulating tank 303, and the second stirring motor 28 is used to drive the stirring rod 29 to rotate.

[0059] The pumping mechanism includes a mud pump 30, which is used to input low-moisture mud from the mixing chamber 202 into the fluidized solidified soil preparation tank 17, which is used to prepare fluidized solidified soil.

[0060] Working principle:

[0061] When in use, high cement slurry is injected into the crushing chamber 201 and large particles of impurities are removed by the primary screening mechanism; the slurry under the screen enters the multi-stage crushing mechanism, and after crushing, it is discharged into the mixing chamber 202 of the slurry dewatering tank 2.

[0062] The crushed sludge enters the mixing chamber 202. Through the spraying mechanism, a desiccant is sprayed first, followed by a flocculant. At the same time, the mixture is stirred to allow it to react fully, forming flocs and releasing water. Then, a large number of air bubbles are introduced into the mixing chamber 202 through the aerator 14, causing the air bubbles to carry impurities and oil in the sludge to float to the surface. Subsequently, the scraper 18 collects the suspended matter and oil on the surface of the sludge and outputs it to the collection box 4. After adding flocculant for a certain period of time, the DC power supply is turned on to energize the electrodes. The cathode block 24 and the anode block 25 are energized, and an electric field is established between the cathode block 24 and the anode block 25. The electric field causes the cations (such as hydrogen ions and sodium ions) in the double electric layer of the sludge particles to carry water molecules toward the cathode. The water molecules penetrate the filter screen 26 near the cathode and are discharged into the water collection tank 301.

[0063] The supernatant in the water collection tank 301 is pumped into the purification tank 302 by the transfer pump 27. After purification, the supernatant is selected to prepare drilling fluid again. At the same time, the low water content mud in the mixing chamber 202 is input into the fluidized solidified soil preparation tank 17 by the mud pump 30 to prepare fluidized solidified soil.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
