Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of rock debris collection and processing, and in particular relates to a rock debris cleaning and processing device and an automatic rock debris collection and cleaning system. BACKGROUND

[0002] Logging is an important link in oil and gas drilling engineering, and through recording and analyzing various information and rock debris samples in the drilling process, scientific basis is provided for geological research, oil and gas exploration and drilling engineering; therefore, it is very important to obtain representative rock debris samples in a timely manner during drilling, and traditional manual sampling is prone to insufficient sample weight and delayed sampling, resulting in inaccurate rock debris analysis results; usually, it can only be performed intermittently during drilling; and with the rapid development of drilling technology today, drilling speed has been greatly improved, and it is required to sample and analyze rock debris once every 1-2 meters of drilling, and the rock debris is returned at a high speed, and manual sampling often cannot keep up in time, and the large interval of rock debris sampling time cannot accurately reflect the continuous change of the formation; secondly, during the cleaning process of the rock debris, improper manual operation can easily cause the loss of small particles, resulting in distorted samples and failing to accurately reflect the geological information; at the same time, incomplete manual cleaning can also cause mud, oil stains or other impurities remaining on the surface of the rock debris to cover the color, luster and other properties of the minerals, causing the geologists to misjudge the lithology; especially in directional wells, horizontal wells or complex formations, the migration and return of the rock debris are more complex, and manual sampling is difficult to accurately capture the changes of the rock debris, and important geological information is easily missed; currently, there are many automatic rock debris collecting and washing devices on the market, but they generally have the following problems:

[0003] Automatic collecting and washing can only ensure timeliness, but cannot achieve sample continuity, and the cleaning of the rock debris is not thorough; therefore, there is an urgent need for a rock debris collecting and washing device that can not only ensure the representativeness of the sample, but also ensure the continuity and timeliness of the rock debris collection.

[0004] The existing Chinese invention patent CN201710062598.0 discloses a screening device and an intelligent rock debris washing machine, which comprises a cross beam, a support, a vibrating device arranged on the cross beam, a water receiving groove connected to the bottom of the cross beam, an upper layer vibrating screen, a middle layer vibrating screen and a bottom layer vibrating screen arranged on the support in sequence and at intervals along the falling direction of the rock debris, a sand receiving funnel, a rotating disc arranged at the bottom outlet of the sand receiving funnel, a plurality of filter cartridges arranged on the rotating disc and used for receiving the rock debris leaked from the outlet, and a pressure spraying device arranged at the opening direction of the filter cartridges and used for washing the rock debris in the filter cartridges. The screening device can filter out the rock debris with large block diameter and collect the rock debris with small block diameter for research, and the process is simple and convenient. The pressure spraying device can flush the rock debris in the filter cartridges, and the automation of rock debris collection and flushing can be realized through the device. However, the filter cartridges containing the rock debris samples still need to be manually put into and taken out, which affects the overall processing efficiency. Meanwhile, a large amount of moisture is left in the rock debris in the filter cartridges after being flushed by the pressure spraying device, which prolongs the processing time of the subsequent rock debris drying link, and the continuity and timeliness of the collection requirement cannot be guaranteed. The length of the rock debris sample collection and processing time directly affects the collection quality of the rock debris samples and the completeness and accuracy of the logging data in the whole logging process.

[0048] In use, the cuttings are filtered through the filter screen 3011 to remove large particles and impurities in the cuttings; then enter the float washing hopper 301 for secondary float washing, in which the buoyancy difference of the drilling fluid is generated by the density difference of the substances in the drilling fluid, and the lighter lubricant (usually graphite powder) and the plugging agent (usually walnut shell) in the drilling fluid are removed; in the float washing hopper 301, the heavy cuttings particles are deposited layer by layer along with the drilling process, slide along the bottom of the hopper to the outlet of the hopper, and are lifted by the bucket of the bucket elevator 302 from bottom to top layer by layer, and then are lifted to the discharge port 3021 and fall into the cuttings tank 6 in the receiving station; the cuttings tank 6 rotates with the station turntable 4, and when the cuttings tank 6 moves to the spraying and drying station, the upper spraying and drying assembly 5 and the lower support 12 clamp the cuttings tank 6, at the same time, the spraying rotating head 5014 tightly seals the upper port of the cuttings tank 6, and when the rotating power device 2 5013 starts, the spraying rotating head 5014 rotates the cuttings tank 6 to remove the water in the cuttings and the mud and impurities attached to the surface of the cuttings; then the impurities filled in the gaps of the cuttings are flushed out by the high-pressure flushing of the spraying rotating head 5014, the cover layer formed on the surface of the cuttings is destroyed, and the particle boundary and the bedding structure of the cuttings are clear; then the second "drying" is carried out to remove the impurities and excess water flushed out by the high-pressure water; after the two "drying" links of the spraying and drying mechanism, the impurities inside and outside the cuttings are completely removed; the cuttings after cleaning have low water content, are sandy in appearance, are cleaner, are brighter in color, are loose and clear after drying, are not clumped, and have high identification.

[0049] It should be noted that the cuttings cleaning and processing device integrates the first-stage filtering, the second-stage float washing, the continuous collection of cuttings, and the single-tank independent cleaning and drying of cuttings samples into a small special-purpose device, realizes the continuous, efficient, and rapid collection of cuttings target samples while drilling, uses the single-tank independent cleaning and drying mode, makes the flushing of cuttings samples more uniform and complete, makes the water removal and impurity removal more obvious, and reduces the amount of cleaning water; the cleaning efficiency and effect are ensured.

[0050] The present application ensures that the cuttings samples are sandy in appearance, are cleaner, are brighter in color, are loose and clear after drying, are not clumped, and have high identification, and at the same time, forms a continuous, accurate, and complete series of cuttings samples, reduces the error between data, greatly improves the coincidence rate of the geological profile, realizes the multi-stage filtering of cuttings, independent spraying, and high-frequency continuous comprehensive operation effect.

[0051] The labor intensity of workers is reduced by about 70%, and the collection efficiency is increased by 3 to 5 times; meanwhile, the cleaning water consumption is reduced to about 1 / 6 of the original, thereby greatly reducing the subsequent sewage treatment amount, and the rock debris automatic collection and cleaning system satisfies the continuity and timeliness requirements of rock debris collection in logging operation, and is more suitable for large-scale drilling operation and high-density sampling requirements.

[0052] The outlet of the hopper is inclined to the bucket elevator 302, so as to facilitate the rock debris to fall into the hopper of the bucket elevator 302 and be lifted upward.

[0053] Please refer to the accompanying drawings Figure 5 The upper spraying and drying assembly 5 further comprises an upper pressing seat 501, a support frame two 5011 and a double-acting cylinder 5012; the support frame two 5011 is fixedly connected with the support frame one 9, and the double-acting cylinder 5012 is fixedly installed on the support frame two 5011; the double-acting cylinder 5012 comprises a top telescopic end and a bottom telescopic end; the top telescopic end of the double-acting cylinder 5012 is fixedly connected with the upper pressing seat 501; the top of the upper pressing seat 501 is provided with a rotary power device two 5013, and the rotary power device two 5013 is a pneumatic motor; the end of the upper pressing seat 501 is provided with a spraying rotary head 5014; the power output end of the rotary power device two 5013 is in transmission connection with the spraying rotary head 5014; the bottom of the spraying rotary head 5014 is fixedly provided with a flange 5015 capable of tightly pressing and sealing the tank opening of the rock debris tank 6; the flange 5015 is made of rubber material and is in the shape of an inverted cone; the flange 5015 is provided with a flushing channel in communication with the spraying opening; the bottom telescopic end of the double-acting cylinder 5012 is fixedly provided with a lower bracket 12; the end of the lower bracket 12 is rotatably provided with a positioning table 1201 capable of limiting the bottom of the rock debris tank 6; the positioning table 1201 is coaxial with the flange 5015 and corresponds in position.

[0054] When the rock debris tank 6 loaded with rock debris is rotated to the lower side of the spraying and drying mechanism along with the work station rotating table 4, the double-acting cylinder 5012 drives the upper pressing seat 501 and the lower bracket 12 to move towards each other, and the rock debris tank 6 is quickly positioned and clamped from the top and bottom directions through the flange 5015 and the positioning table 1201; meanwhile, the flange 5015 made of rubber material can tightly press and seal the rock debris tank 6 from the top; the rotary power device two 5013 (pneumatic motor) drives the spraying rotary head 5014 to rotate, and then drives the rock debris tank 6 to rotate at a high speed; under the action of centrifugal force, the impurities attached to the surface of the rock debris and filled in the gaps of the rock debris are flushed out, the moisture in the rock debris is spun off, and the impurities inside and outside the rock debris can be thoroughly cleaned.

[0055] Please refer to the accompanying drawings Figure 6As shown, the work station rotary table 4 includes a rotary table bottom plate 401, a rotary table top plate 402 and an arc-shaped baffle 403; the rotary table bottom plate 401 is spaced from the rotary table top plate 402, and the rotary table bottom plate 401 and the rotary table top plate 402 are respectively provided with corresponding arc-shaped openings 404; the rotary table bottom plate 401 is provided with a tank support 405 at the arc-shaped opening 404; the arc-shaped baffle 403 is fixedly connected between the rotary table bottom plate 401 and the rotary table top plate 402 at the arc-shaped opening 404, and the arc-shaped baffle 403 and the arc-shaped opening 404 form a clamping groove 406; the rotary table bottom plate 401 is provided with a connecting shaft at the center through a shaft seat, and the connecting shaft is fixedly connected with the top of the power output end of the rotary power device one 407.

[0056] It should be noted that when the rock debris tank 6 is spun dry and high-pressure washed at the clamping groove 406, the water spun out of the rock debris tank 6 will be blocked by the arc-shaped baffle 403, so that the spun and washed water is discharged downward along the arc-shaped baffle 403, reducing the wet corrosion effect on the rotary power device one 407 and the mechanical connection between the rotary table bottom plate 401 and the rotary power device one 407.

[0057] Please refer to the accompanying drawings Figure 7 As shown, the rock debris tank 6 is a conical filter screen barrel, and the top of the rock debris tank 6 is provided with a clamping edge 601 matched with the flange 5015; the opening width of the arc-shaped opening 404 of the rotary table top plate 402 is smaller than the diameter width of the clamping edge 601 and greater than the maximum tank diameter width of the rock debris tank 6; it is ensured that the rock debris tank 6 can be clamped into the clamping groove 406 through the clamping edge 601. The bottom center of the rock debris tank 6 is provided with a concave positioning groove 602; the positioning groove 602 is matched with the positioning table 1201.

[0058] It should be noted that the conical filter screen barrel of the rock debris tank 6 makes it more stable and centered when rotating at high speed, ensuring the stability of the rock debris tank 6 during the spin-drying process; at the same time, a gap with a narrow top and a wide bottom is formed between the rock debris tank 6 and the outer shell 408, facilitating the external discharge of the mud, impurities and water spun out of the rock debris tank 6.

[0063] In use, the sludge and sewage produced by the rock debris lifting and filtering mechanism 3 and the spraying and drying mechanism enter the open sewage collection tank 201, impurities and slurry are deposited in the tank bottom and the sewage pipeline 202, and the impurities and slurry can be sent to the inlet of the screw pump 205 through the second auger 203 and then pumped out through the screw pump 205; the filter box 5 can filter out the light lubricant and plugging agent (usually graphite powder, walnut shell) floating on the surface of the liquid to avoid being brought into the filtering system of the floating washing filter hopper 301 again in the circulation process; it should be noted that the sewage pipeline 202, the second auger 203 and the screw pump 205 can balance the water quantity in the sewage collection tank 201 while purifying the water quality; the water in the sewage collection tank 201 can also be circulated into the filtering system of the floating washing filter hopper 301 through the circulating water pump to flush the filter screen 3011, reduce the adhesion and blockage of the slurry, reduce the viscosity of the slurry, improve the floating washing effect, ensure the overall filtering efficiency and the collection effect of the rock debris target sample.

[0064] For the convenience of movement, universal wheels are arranged at the bottom of the base 10; an electric heater is further arranged on the base 10 in the box body 8; it should be noted that when the external temperature is low, the electric heater can be used to maintain the temperature inside the cleaning and filtering treatment box to prevent the water from freezing and affecting the normal work.

[0065] The box body 8 is a stainless steel shell box body 8, and the stainless steel shell has a certain heat preservation effect.

[0066] The four sets of maintenance doors are respectively: the first maintenance door located at the upper part of the support frame one 9 and placed at the front side of the floating washing filter hopper 301; the second maintenance door located at the upper part of the support frame one 9 and placed at the right side of the floating washing filter hopper 301 and flipped to open and close; the third maintenance door and the fourth maintenance door located at the lower part of the support frame one 9 and placed at the front side of the sewage collection tank 201; the multiple maintenance doors facilitate the maintenance of the equipment by the workers; the maintenance doors are all double-layer door bodies filled with polyurethane inside to prevent the internal temperature from being too low.

[0068] Further, the bottom of the sewage collection tank 201 is conical to facilitate the rapid gathering and deposition of solid particles such as slurry and impurities at the bottom; at the same time, in order to prevent impurities such as silt from adhering to the inner wall of the sewage collection tank 201, a high-frequency vibrator can be arranged on the inner wall of the sewage collection tank 201.

[0069] Example 2:

[0070] Please refer to the attachedFigure 9 , attached Figure 10 As shown in the accompanying drawings, the present application provides a kind of rock debris automatic collection cleaning system, still include rock debris collection mechanism 1, rock debris collection mechanism 1 includes sampling pipeline 101, conveying pipe 102, circulating water pipe 103, motor one 104, auger one 105, cover plate 106;At least 2 feed ports are distributed in the top of sampling pipeline 101 transversely, the auger one 105 that rock debris is pushed to conveying pipe inside is arranged in sampling pipeline 101, the import end of auger one 105 is fixedly connected with the power output end of motor one 104, the export end of auger one 105 is communicated with the import of conveying pipe 102, the export of conveying pipe 102 is communicated with the feed port of the top of float washing filter hopper 301.

[0071] When using, rock debris enters sampling pipeline 101, and auger one 105 is driven under the motor one 104 and applies mechanical thrust to the rock debris in sampling pipeline 101, because the viscosity of rock debris is high, the resistance is big when auger one 105 is pushed, and the conveying speed of rock debris is influenced, water in sewage collection tank 201 is continuously injected into sampling pipeline 101 using circulating water pipe 103;Under the washing and carrying effect of water flow, the viscosity of rock debris reduces, and the conveying speed accelerates, and rock debris can be quickly conveyed through conveying pipe 102 to the feed port of the top of float washing filter hopper 301 and enter rock debris cleaning treatment device to carry out subsequent cleaning treatment, meet the continuity and timeliness requirement of rock debris sample collection.

[0072] The automatic cuttings collection and cleaning system continuously transports the cuttings retrieved during drilling to the cuttings cleaning and processing unit using a cuttings collection mechanism. After primary filtration and secondary flotation by the cuttings lifting and filtering mechanism, larger cuttings, impurities, and surface-adhering mud are removed, resulting in a filtered and flotated cuttings target sample. This sample is then continuously fed into a separate cuttings tank on a turntable using a bucket elevator and transported to a spray drying mechanism. The spray drying mechanism performs a first "spinning" process to remove moisture and surface-adhering mud from the cuttings. The process involves removing mud and impurities; then, "high-pressure washing" flushes out the impurities filling the gaps in the rock fragments, breaking down the covering layer formed on the surface of the rock fragments, making the particle boundaries and bedding structure of the rock fragments clear; finally, a second "spray drying" process by a spray drying mechanism removes impurities and excess water washed out by high-pressure water, thoroughly cleaning the impurities inside and outside the rock fragments; through the above steps, the cleaned rock fragments have a low moisture content, an overall sandy texture, are cleaner, have a brighter color, and after drying, the surface is loose and clear, without clumping, making the rock fragments highly identifiable. The sludge and wastewater generated in the cuttings cleaning and treatment device can also be treated in a timely manner through the mud and waste liquid recovery mechanism 2, and the wastewater can be preliminarily filtered and recycled again. The entire cuttings collection and cleaning process is highly automated, with a short cycle time from collection to cleaning and treatment, and high efficiency, meeting the requirements of logging work for the continuity and timeliness of cuttings collection. At the same time, the cleaned cuttings samples have fewer impurities, lower water content, and higher integrity. The loose texture is highly representative, and an accurate data analysis spectrum can be obtained through subsequent cuttings analysis, reducing the error between data and greatly improving the consistency rate of geological profiles, which has important guiding significance for subsequent geological analysis work.

[0073] See appendix Figure 9 As shown, multiple cover plates 106 are hinged at the inlet at the top of the sampling pipe 101.

[0074] It should be noted that each cover plate 106 can be opened or closed. The number of open cover plates 106 controls the size of the opening for cuttings inflow, thereby controlling the amount of cuttings flowing into the sampler per unit time, since the weight of the sampled cuttings is generally required to be around 500g. At the same time, the position of the collected cuttings can be adjusted by opening cover plates 106 at different positions. Since cuttings are required to be sampled and analyzed every 1 to 2 meters during drilling, the sampling time interval is short. By changing the position of the cover plates 106, it is ensured that the collected cuttings are more representative of the situation at different locations in the formation, further improving the representativeness of the cuttings collection and the consistency rate of the cuttings profile, and improving the accuracy of the logging data.

[0075] The following table compares the cleaning time and water consumption of manual and this equipment cleaning methods for cuttings from different geological layers under the same logging scenario:

[0076]

[0077] As can be seen from the table above, for different sand samples, the cleaning time using the cleaning method of the present invention is significantly reduced compared to traditional manual cleaning, reducing the labor intensity of workers by about 70% and increasing the collection efficiency by 3 to 5 times; at the same time, the cleaning water consumption is reduced to about 1 / 6 of the original, greatly reducing the subsequent wastewater treatment volume. Therefore, the automatic rock cuttings collection and cleaning system of the present invention meets the requirements of continuity and timeliness of rock cuttings collection in logging operations, and is more adaptable to large-scale drilling operations and high-density sampling needs.

[0078] See appendix Figure 12 Appendix Figure 13 As shown, rock chips that have undergone machine washing and spin-drying to remove moisture have a loose and clear surface after drying and do not clump together; while rock chips that are manually washed without spin-drying have clumps on the surface after drying, affecting their visibility. Rock chips that have been machine washed have low moisture content, are generally sandy, are cleaner, have a brighter color, and require less subsequent baking time; while rock chips that have been manually washed have high moisture content, are dirty in color, have more impurities, and require more subsequent baking time, affecting overall efficiency.

[0079] The following is in conjunction with the appendix Figures 1-13 The implementation principle of this invention is described as follows:

[0080] In use, after the cuttings enter the sampling pipeline 101, the auger 105 is driven by the motor 104 to apply mechanical thrust to the cuttings entering the sampling pipeline 101, and the circulating water pipe 103 is used to continuously inject water in the sewage collecting tank 201 into the sampling pipeline 101; under the washing and carrying action of the water flow, the viscosity of the cuttings is reduced, and the cuttings can quickly pass through the conveying pipe 102 and be conveyed to the top of the float washing filter hopper 301, and enter the cuttings cleaning and processing device; when the cuttings pass through the filter screen 3011 at the feed inlet of the float washing filter hopper 301, the larger particles of cuttings and impurities are filtered out and then enter the float washing filter hopper 301 for float washing; during the float washing process, the different buoyancy differences of the drilling fluid substances are used to filter out the lighter lubricant (usually graphite powder) and the plugging agent (usually walnut shell) in the cuttings through the float washing sewage outlet 3012 and the filter box 11, and the cuttings after float washing are deposited to the bottom of the float washing filter hopper 301, and are fished out layer by layer from bottom to top by the bucket of the bucket elevator 302 and lifted to the discharge port 3021 to fall into the cuttings tank 6 at the receiving station; the cuttings tank 6 rotates with the work station turntable 4, and when the cuttings tank 6 moves to the spray drying station, the rotary power device one 407 (servo motor) drives the work station turntable 4 to rotate clockwise intermittently; the empty cuttings tank 6 slides into the clamping groove 406 on the work station turntable 4 under the action of gravity every time the work station turntable 4 rotates clockwise once, and the empty cuttings tank 6 can be placed by the operator every time; the work station turntable 4 rotates clockwise once, and the empty cuttings tank 6 on the inlet guide rail 409 enters one, and the automatic tank loading action is completed; the cuttings tank 6 rotates with the work station turntable 4 to the receiving station, and the cuttings after cleaning and drying treatment fall into the cuttings tank 6; when the cuttings tank 6 containing cuttings rotates with the work station turntable 4 to below the spray drying mechanism, the double-acting cylinder 5012 drives the upper pressing seat 501 and the lower supporting seat 12 to move towards each other, and the cuttings tank 6 is quickly positioned and clamped and fixed from the top and bottom directions through the flange 5015 and the positioning table 1201, and at the same time, the flange 5015 can compact and seal the top of the cuttings tank 6; at this time, the rotary power device two 5013 (pneumatic motor) drives the spray rotating head 5014 to rotate through the transmission device, and then drives the cuttings tank 6 to rotate at high speed; under the action of centrifugal force, the mud, impurities and water in the cuttings tank 6 are shaken out through the filter screen on the cuttings tank 6 and discharged from the bottom of the tank supporting 405, and then high-pressure clean water is injected into the cuttings tank 6 through the water inlet pipe 5016 for secondary flushing to flush out the impurities filled in the gaps of the cuttings, and then the cuttings tank 6 is rotated by the rotary power device two 5013 to dry and remove the impurities and excess water washed out by the high-pressure clean water, so that the cuttings are thoroughly cleaned; with the rotation of the work station turntable 4, the cleaned cuttings tank 6 slides out from the clamping groove 406 at the outlet guide rail 410, and the tank unloading is completed.The sewage and sludge generated in the rock debris cleaning treatment device enter the sewage collecting tank 201, and the slurry and impurities will be deposited in the conical bottom of the sewage collecting tank 201 in succession. The motor two 204 drives the auger two 203 to rotate, and the auger two 203 can send the impurities and slurry to the inlet of the screw pump 205, and then pump out through the screw pump 205. The water in the sewage collecting tank 201 can also be circulated into the filtering system of the floating washing filter hopper 301 through the circulating water pump, to flush the filter screen 3011, reduce the adhesion and blockage of the slurry, reduce the viscosity of the slurry, and improve the floating washing effect.
