Description

Technical Field

[0001] The invention relates to the technical field of mud treatment, and in particular to a mud circulation treatment method for directional drilling in ecologically sensitive areas. Background Art

[0002] During directional drilling construction, mud is used to remove the debris inside the hole. The mud also acts as a lubricant. Due to the huge amount of mud used, and the fact that these waste liquids contain drilling fluid additives, drill cuttings, soluble salts, heavy metal ions and other harmful substances, if they are discharged directly without treatment, they will cause serious pollution and harm to the natural environment such as soil and water sources. In some ecologically sensitive areas, the requirements are even more stringent. Therefore, after the construction is completed, the mud will be treated on site to separate the water and mud. It can only be discharged after the water quality meets the requirements.

[0003] When treating the mud, it is necessary to go through preliminary sedimentation, stirring and adding drugs, adjust the mud concentration and finally filter to separate the mud and water. After preliminary sedimentation inside the mud pool, it will be transported to the mixing barrel for stirring and adding drugs. The traditional mixing barrel is simply a stirring roller that stirs the mud in a circular motion. When the moving speed is reached, the mud will keep moving synchronously with the stirring roller. After adding the agent, the mixing effect of the agent and the mud will become worse. Only the mixing is faster in the middle position. The mud and the agent in the outer position will only gradually dissolve and mix, resulting in uneven agent onset speed. Part of the mud may become flocculated, and part of the mud has not been mixed with the agent. At the same time, after the traditional mixing tank stops the stirring roller, the mud will rotate for a certain period of time under the action of inertia. The time waiting for the mud to stop will delay the progress of the mud treatment project and reduce the project efficiency. Therefore, the present application provides a mud circulation treatment method for directional drilling in ecologically sensitive areas to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a directional drilling mud circulation treatment method for ecologically sensitive areas to solve the problems of poor mixing effect of reagents and mud during stirring in the existing stirring tank and slow stabilization of the mud.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A directional drilling mud circulation treatment method for ecologically sensitive areas. The specific treatment method process is as follows:

[0007] S1. Pour the slurry into the sedimentation tank and let it stand for a period of time to allow the heavier solid particles to sink naturally. Through natural sedimentation or adding flocculants, the solid particles in the slurry are initially settled, the water content of the slurry is reduced, and the burden for subsequent treatment is reduced;

[0008] S2. Preliminary sedimentation of solid particles in the mud is carried out by natural sedimentation or addition of flocculants, so as to reduce the water content of the mud and reduce the burden for subsequent treatment. The solid particles in the mud are evenly dispersed, and an appropriate amount of chemical agents are added and stirred for a period of time to fully mix the agents with the mud. The added agents fully react with the mud to improve the effect of subsequent solid-liquid separation, and then the mud is allowed to settle to separate some of the water in the mud;

[0009] S3. The clean water after separation is pumped out, and then the mud is transported to a filter press or other solid-liquid separation equipment to filter out the water in the mud, so that the mud in the mud forms a mud cake, and then the mud cake is transported away by a transport vehicle for recovery or backfilling.

[0013] Optionally, the locking mechanism comprises a locking buckle body, a flip locking block is rotatably connected inside the locking buckle body, a first limiting block is slidably connected inside the locking buckle body, and a pair of springs are fixedly connected to one end of the first limiting block away from the flip locking block;

[0014] The locking buckle body is fixedly connected to the inner wall of the main tank body, and the opening of the locking buckle body faces the supporting slide bar. The locking buckle body is located between the supporting slide bar and the blocking plate. The flip locking block is in conflict with the supporting slide bar, and the first limit block is in conflict with the flip locking block.

[0015] Optionally, when the blocking plate flips, it will pull the supporting slide bar to move through the supporting plate, and the supporting slide bar will move toward the inside of the locking buckle body. The supporting slide bar will squeeze the flip locking block inside the locking buckle body to flip it, so that the flip locking block squeezes and pushes the first limit block to move, so that the flip locking block flips to fix the supporting slide bar, and at the same time, the first limit block is reset under the push of the spring and conflicts with the flip locking block.

[0016] Optionally, the unlocking mechanism includes a transverse pull rod and a movable stopper, one end of the transverse pull rod is hinged with a tilting rod, the middle of the tilting rod is movably connected with a rotating shaft, and a second limit block is arranged on the side of the movable stopper.

[0017] Optionally, the transverse pull rod passes through the interior of the locking buckle body and extends to the interior of the locking buckle body, the transverse pull rod is located in the middle of the spring and is fixedly connected to the first limit block, the rotating shaft is rotatably connected to the inner wall of the main tank body, the rotating shaft is slidably connected to the tilting rod, the movable block is rotatably connected to the main tank body, the movable block is L-shaped, the second limit block is located on the side of the movable block away from the L-shaped protruding end, and the movable block abuts against the second limit block.

[0018] Optionally, the upper end of the tilting rod is flipped toward the side of the locking buckle body, and the lower end of the tilting rod is flipped synchronously with the rotation axis as the axis. The bottom of the tilting rod pulls the first limit block to move through the transverse pull rod to release the limit on the flip locking block, and then the movable block is pushed to contact the second limit block, so that the movable block contacts the tilting rod, so that the tilting rod remains in a tilted state.

[0019] Optionally, the synchronization mechanism includes a rotating frame, the outer extending ends of the rotating frame are respectively hinged with push rods, the ends of the push rods away from the rotating frame are hinged with horizontal pull rods, and the upper end of the support frame is provided with a first slide groove and a second slide groove in a circular shape.

By opening the baffle plate, the circular motion of the mud will generate a vortex on the back of the baffle plate when passing through the baffle plate, so that the mud is fully mixed with the reagent inside the vortex. At the same time, after stopping the stirring, the baffle plate will block the rotation of the mud under the action of inertia, so that the mud will quickly stop and begin to settle.

[0023] By setting a locking mechanism and an unlocking mechanism, it is convenient to control the locking and unlocking of the blocking plate after it is opened. When the blocking plate is opened, the supporting slide bar will be pulled to move by the supporting plate, so that the supporting slide bar enters the interior of the locking buckle body, and the supporting slide bar is fixed by the flip locking block and the locking buckle body, so that the supporting slide bar and the supporting plate support the blocking plate. When unlocking is required, the upper end of the tilting rod is flipped by toggling the tilting rod, and the first limit block is pulled to move by the bottom of the tilting rod through the horizontal pull rod, so that the first limit block releases the limit on the flip locking block, and the flip locking block limits the support slide bar, so that the blocking plate can move freely.

[0024] By setting up a synchronization mechanism, it is convenient to simultaneously control the opening or closing of the blocking plate. The rotating frame drives multiple push rods to move synchronously, so that the push rods push the horizontal pull rods to pull the blocking plate to move, so that the blocking plate flips to open or reset, thereby controlling the opening or resetting of the blocking plate at one time.

[0043] like Figures 1 to 9 As shown, an embodiment of the present invention provides a directional drilling mud circulation treatment method for ecologically sensitive areas. The specific treatment method process is as follows:

[0044] S1. The slurry is introduced into the sedimentation tank and allowed to stand for a period of time to allow the heavier solid particles to sink naturally. The solid particles in the slurry are initially settled by natural sedimentation or by adding flocculants, thereby reducing the water content of the slurry and reducing the burden for subsequent treatment.

[0045] S2. Preliminary sedimentation of solid particles in the mud is carried out by natural sedimentation or addition of flocculants, so as to reduce the water content of the mud and reduce the burden for subsequent treatment. The solid particles in the mud are evenly dispersed, and an appropriate amount of chemical agents are added and stirred for a period of time to fully mix the agents with the mud. The added agents fully react with the mud to improve the effect of subsequent solid-liquid separation, and then the mud is allowed to settle to separate some of the water in the mud;

[0046] S3. The clean water after separation is pumped out, and then the mud is transported to a filter press or other solid-liquid separation equipment to filter out the water in the mud, so that the mud in the mud forms a mud cake, and then the mud cake is transported away by a transport vehicle for recovery or backfilling.

[0047] like Figures 1 to 9As shown, a directional drilling mud circulation treatment equipment for ecologically sensitive areas includes a main tank body 1, a stirring rod 2 is installed inside the main tank body 1, a support frame 3 is fixedly connected to the top of the main tank body 1, a blocking mechanism 4 and a locking mechanism 5 are distributed in an annular shape inside the main tank body 1, an unlocking mechanism 6 is arranged on the side of the locking mechanism 5, a synchronization mechanism 7 is movably connected to the top of the support frame 3, a synchronization mechanism 7 and a drainage pipe 8 are installed on the top of the main tank body 1, and a slag discharge pipe 10 is opened at the bottom of the main tank body 1;

[0048] Among them, the blocking mechanism 4 includes a blocking plate 41, a pair of transverse slide rails 42 and a bottom slide rail 45, a support slide rod 43 is slidably connected between the pair of transverse slide rails 42, support plates 44 are hinged at both ends of the support slide rod 43, and a water outlet 46 is opened at the bottom of the blocking plate 41.

[0049] The above scheme is adopted: by pushing the rotating frame 71 to rotate, the rotating frame 71 pulls the blocking plate 41 to move through the push rod 72 and the horizontal pull rod 73, so that the blocking plate 41 is flipped and opened. At the same time when the blocking plate 41 is flipped and opened, the blocking plate 41 will pull the supporting slide bar 43 toward the blocking plate 41 through the supporting plate 44, so that the supporting slide bar 43 enters the interior of the locking buckle body 51, and the supporting slide bar 43 is fixed by the flip locking block 52 and the locking buckle body 51, so that the supporting slide bar 43 and the supporting plate 44 support the blocking plate 41, and then the stirring rod 2 is started to stir the mud. The mud will generate a vortex on the back of the baffle plate 41, causing the depression at the axis to disappear and the liquid surface to be flat. At this time, a flocculant is added to the main tank body 1. Due to the vortex generated behind the baffle plate 41, the flocculant and the mud can be mixed faster. By mixing the flocculant and the mud faster, the dosage of the flocculant can be better controlled to better cope with the mud generated by drilling in different areas, so that the solid particles in the mud can be better separated from the water, so that it can be safely discharged into the ecologically sensitive area after treatment.

[0050] like Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the blocking plate 41 is rotatably connected to the main tank body 1, the blocking plate 41 is consistent in shape with the inner wall of the main tank body 1, the transverse slide rail 42 is fixedly connected to the inner wall of the main tank body 1, the transverse slide rail 42 is located at the end of the blocking plate 41 away from the hinge with the main tank body 1, the end of the support plate 44 away from the support slide rod 43 is rotatably connected to the blocking plate 41, and the bottom slide rail 45 is fixedly connected to the bottom of the main tank body 1 and is slidably connected to the blocking plate 41.

[0051] The above scheme is adopted: by setting up the blocking mechanism 4, the blocking plate 41 can partially block the circular motion of the mud inside the tank body for the rotating liquid, and the blocking plate 41 is set to be consistent with the inner wall shape of the main tank body 1, so that the blocking plate 41 can fit with the inner wall of the main tank body 1 when not in use, and by setting up a transverse slide rail 42 and a supporting slide rod 43, the supporting slide rod 43 slides on the transverse slide rail 42, so that the supporting slide rod 43 can flexibly move with the supporting plate 44, and the supporting plate 44 set between the supporting slide rod 43 and the blocking plate 41 can support the blocking plate 41 after the blocking plate 41 is flipped and opened, and by setting up a bottom slide rail 45, the blocking plate 41 can be conveniently flipped and moved, and the water outlet 46 opened at the bottom of the main tank body 1 is used to flush out the solid sediment retained in the gap between the main tank body 1 and the blocking plate 41 when the main tank body 1 is cleaned after use.

[0052] like Figures 5 to 8 As shown, the locking mechanism 5 includes a locking buckle body 51, a flip locking block 52 is rotatably connected inside the locking buckle body 51, a first limit block 53 is slidably connected inside the locking buckle body 51, and a pair of springs 54 are fixedly connected to the end of the first limit block 53 away from the flip locking block 52. The locking buckle body 51 is fixedly connected to the inner wall of the main tank body 1, and the opening of the locking buckle body 51 faces the supporting slide bar 43. The locking buckle body 51 is located between the supporting slide bar 43 and the blocking plate 41, the flip locking block 52 is in conflict with the supporting slide bar 43, and the first limit block 53 is in conflict with the flip locking block 52.

[0053] The above scheme is adopted: the design of the locking mechanism 5 can fix the supporting slide bar 43 when the blocking plate 41 is flipped and opened, so that the supporting slide bar 43 and the supporting plate 44 can stably support the blocking plate 41, and by providing a locking buckle body 51 and a flip locking card block 52, the locking buckle body 51 is supported, and the flip locking card block 52 that can be flipped is used to limit the supporting slide bar 43 entering the locking buckle body 51. When the supporting slide bar 43 enters the locking buckle body 51, it will first squeeze the flip locking card block 52 to flip, and at the same time, the flip locking card block 52 will squeeze the first limiting block 53 to move. After the flip locking card block 52 passes over the first limiting block 53, the first limiting block 53 is reset under the push of the spring 54. The first limiting block 53 conflicts with the flip locking card block 52 after flipping. Figure 8 As shown, the first limiting block 53 limits the flip locking block 52 so that the flip locking block 52 is locked, thereby limiting the support slide bar 43 inside the locking buckle body 51, thereby completing the fixation of the support slide bar 43.

[0054] like Figures 5 to 8As shown, when the blocking plate 41 flips, it will pull the supporting slide bar 43 to move through the supporting plate 44, and the supporting slide bar 43 will move toward the inside of the locking buckle body 51. The supporting slide bar 43 will squeeze the flip locking block 52 inside the locking buckle body 51 to flip it, so that the flip locking block 52 squeezes and pushes the first limit block 53 to move, so that the flip locking block 52 flips to fix the supporting slide bar 43, and at the same time, the first limit block 53 is reset under the push of the spring 54 and conflicts with the flip locking block 52.

[0055] The above solution is adopted: when the blocking plate 41 is flipped and opened, the blocking plate 41 will pull the supporting slide bar 43 to move synchronously through the supporting plate 44, so that the supporting slide bar 43 moves toward the inside of the locking buckle body 51. When the supporting slide bar 43 moves to the inside of the locking buckle body 51, it will first squeeze the flip locking card block 52 to flip, and the synchronous flip locking card block 52 will squeeze and push the first limit block 53 to move. After the supporting slide bar 43 completely enters the inside of the locking buckle body 51, the flip locking card block 52 When the flipping is completed, the support slide bar 43 is fixed, and the flip locking block 52 squeezes one end of the first limit block 53 to pass over the first limit block 53, so that the first limit block 53 is reset and conflicts with the flip locking block 52 under the push of the spring 54, limiting the rotation of the flip locking block 52, so that the support slide bar 43 is fixed inside the locking buckle body 51 and the flip locking block 52, so that the support slide bar 43 and the support plate 44 can stably support the blocking plate 41, so that the blocking plate 41 can block the flow of mud.

[0056] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the unlocking mechanism 6 includes a transverse pull rod 61 and a movable block 64, one end of the transverse pull rod 61 is hinged with a tilting rod 62, the middle part of the tilting rod 62 is movably connected with a rotating shaft 63, and a second limit block 65 is arranged on the side of the movable block 64, the transverse pull rod 61 passes through the interior of the locking buckle body 51 and extends to the interior of the locking buckle body 51, the transverse pull rod 61 is located in the middle of the spring 54 and is fixedly connected to the first limit block 53, the rotating shaft 63 is rotatably connected to the inner wall of the main tank body 1, the rotating shaft 63 is slidably connected to the tilting rod 62, the movable block 64 is rotatably connected to the main tank body 1, the movable block 64 is L-shaped, the second limit block 65 is located on the side of the movable block 64 away from the L-shaped protruding end, and the movable block 64 abuts against the second limit block 65.

[0057] The above scheme is adopted: the design of the unlocking mechanism 6 can facilitate the release of the lock of the flip locking block 52 by the first limit block 53 after the blocking plate 41 is used, so that the supporting slide bar 43 can push the flip locking block 52 to flip and reset, and by setting a transverse pull rod 61, the transverse pull rod 61 is connected to the first limit block 53, so that the first limit block 53 moves under the pull of the transverse pull rod 61, and the limit on the flip locking block 52 is released. The tilting rod 62 hinged at one end of the transverse pull rod 61 away from the first limit block 53 can pull the transverse pull rod 61 to move. The rotating shaft 63 arranged in the middle of the tilting rod 62 hinges the rotating shaft 63 with the main tank body 1, and the rotating shaft 63 is slidably connected with the tilting rod 62, so that the tilting rod 62 can rotate around the rotating shaft 63 as the axis, and the upper end of the tilting rod 62 is moved to pry the lower end of the tilting rod 62 to pull the horizontal pull rod 61 to move. The movable stopper 64 and the movable stopper 64 arranged on the top of the main tank body 1 can temporarily limit the tilting rod 62 after flipping, so that the same staff can flip the tilting rod 62 in turn, and release the lock of each first limit block 53 on the flip locking block 52 in turn.

[0058] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the upper end of the tilting rod 62 is flipped toward the side of the locking buckle body 51, and the lower end of the tilting rod 62 is flipped synchronously with the rotating shaft 63 as the axis. The bottom of the tilting rod 62 pulls the first limit block 53 to move through the transverse pull rod 61, releasing the limit on the flip locking block 52, and then the movable stop block 64 is pushed to contact the second limit block 65, so that the movable stop block 64 is in contact with the tilting rod 62, so that the tilting rod 62 remains in a tilted state.

[0059] The above scheme is adopted: the staff member moves the upper end of the tilting rod 62 toward the side of the locking buckle body 51 to flip it. At this time, the tilting rod 62 flips around the rotating shaft 63, and the first limit block 53 is pulled toward the side of the blocking plate 41 by the bottom of the tilting rod 62 through the horizontal pull rod 61, so that the first limit block 53 releases the limit on the flip locking block 52. At this time, the staff keeps the position of the tilting rod 62 unchanged, and then moves the movable stop block 64 to contact the second limit block 65. When the tilting rod 62 is released, the bottom of the tilting rod 62 will be reset a short distance under the push of the spring 54, and then the movable stop block 64 will contact the top of the tilting rod 62 to block the tilting rod 62, so that the tilting rod 62 remains in a tilted state.

[0060] like Figure 2 , Figure 3 and Fig. 9As shown, the synchronization mechanism 7 includes a rotating frame 71, and the extended ends on the outer side of the rotating frame 71 are respectively hinged with push rods 72, and the end of the push rod 72 away from the rotating frame 71 is hinged with a horizontal pull rod 73, and the upper end of the support frame 3 is provided with a first slide groove 74 and a second slide groove 75 in a ring-shaped distribution. The middle part of the rotating frame 71 is rotatably connected to the support frame 3, and the outer ring of the rotating frame 71 is slidably connected to the inside of the first slide groove 74 at the hinge between the push rod 72, and the one end of the horizontal pull rod 73 and the push rod 72 is slidably connected to the inside of the second slide groove 75, and the end of the horizontal pull rod 73 away from the push rod 72 is hinged to the top of the blocking plate 41.

[0061] The above scheme is adopted: by setting the synchronous mechanism 7, the blocking plate 41 can be pulled and flipped to open or the blocking plate 41 can be pushed to reset, and the rotating frame 71 drives the multiple push rods 72 to move synchronously, and the rotating frame 71 is rotatably connected to the supporting frame 3, so that the rotating frame 71 keeps stable rotation. By setting the push rod 72 and the horizontal pull rod 73, the horizontal pull rod 73 can be pushed by the push rod 72 to move, and the two ends of the push rod 72 are respectively slidably connected to the inside of the second slide slot 75 of the first slide slot 44, so that when one end of the push rod 72 slides along the horizontal pull rod 73, the other end of the push rod 72 slides inward or outward along the second slide slot 75, and the sliding of the push rod 72 inside the second slide slot 75 can drive the horizontal pull rod 73 to move, and then the blocking plate 41 is pulled to move by the horizontal pull rod 73, so that the blocking plate 41 is flipped to open or reset, and the opening or resetting of the blocking plate 41 can be controlled at one time.

[0062] The working principle provided by the present invention is that after the mud to be cleaned is poured into the main tank body 1, the rotating frame 71 is first pushed to rotate toward the side close to the blocking plate 41, so that the rotating frame 71 pushes the push rod 72 to move, and the push rod 72 pushes the horizontal pull rod 73 to pull the blocking plate 41 to move, so that the blocking plate 41 is flipped and opened. When the blocking plate 41 is flipped and opened, the blocking plate 41 will pull the supporting slide bar 43 toward the blocking plate 41 through the supporting plate 44, so that the supporting slide bar 43 enters the locking buckle body 51, and at the same time pushes the flip locking block 52 to flip, and the flip locking block 52 and The locking buckle body 51 fixes the support slide bar 43, so that the support slide bar 43 and the support plate 44 support the blocking plate 41, and then starts the stirring rod 2, so that the stirring rod 2 starts to stir the mud inside the main tank body 1. When the stirring rod 2 stirs the mud, it drives the mud to move in a circular motion. At this time, since the blocking plate 41 blocks the circular motion of the mud, the mud will generate a vortex on the back of the blocking plate 41, so that the concave at the axis disappears and the liquid surface is flat. At this time, flocculant is added to the inside of the main tank body 1. Due to the vortex generated behind the blocking plate 41, the flocculant and the mud can be mixed faster.

[0063] After the flocculation is produced, the stirring rod 2 is closed. After the stirring rod 2 is closed, due to the obstruction of the blocking plate 41, the mud flow inside the main tank body 1 will stop and calm down more quickly. After the mud is calm, the upper end of the tilting rod 62 is flipped, and the first limit block 53 is pulled to move by the bottom of the tilting rod 62 through the horizontal pull rod 61, so that the first limit block 53 releases the limit on the flip locking block 52, and at the same time, the movable stopper 64 is flipped to make the movable stopper 64 abut against the top of the tilting rod 62 to block the tilting rod 62. After all the first limit blocks 53 are unlocked, the rotating frame 71 is pushed to reset, so that the push rod 72 pulls the horizontal pull rod 73 to push the blocking plate 41 to reset, and the blocking plate 41 is closed, and the mud can be waited for sedimentation and stratification. After the mud is stratified and clear water is produced, the clear water is first pumped out through the drain pipe 8, and then the mud is pumped out through the slurry discharge pipe 9 for the next step of filter pressing to separate the mud into clear water and mud cake, and then the clear water is processed to complete the processing of the mud.
