Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas drilling, in particular to a cuttings separation device for oil and gas resource exploration. Background Art

[0002] Oil and gas exploration refers to geological surveys, geophysical exploration, drilling, and related activities conducted to identify prospective areas and determine oil and gas reserves. It is the first critical step in oil and gas extraction. Principles employed include seismic stratigraphy and numerical simulation technology, and methods employed include seismic exploration and gravity exploration. Oil and gas exploration consists of three phases: regional survey, trap exploration, and reservoir analysis and evaluation. Trap exploration involves drilling in areas where oil and gas resources may be present. During drilling, rock cuttings and cores must be promptly obtained to facilitate subsequent evaluation of the hydrocarbon potential of the strata within the trap.

[0003] When core drilling is needed, operators use specialized coring drill bits. To obtain cuttings, operators use a drilling pump to pump drilling fluid (typically a mixture of water, clay, and chemical additives) along the drill pipe to the drill bit. After exiting the drill bit, the drilling fluid, carrying cuttings from the encountered formation, returns to the surface along the annular space between the drill pipe and the wellbore wall. Pipes connected to the annular space and the drilling fluid pump attached to the pipe then discharge the cuttings-laden drilling fluid.

[0004] Drilling fluid containing cuttings needs to be separated from the drilling fluid before the cuttings can be analyzed. Currently, the common method for separating cuttings is to install a vibrating screen at the wellhead. Pipelines drain the drilling fluid containing cuttings onto a vibrating screen with coarse meshes to filter out large pieces of cuttings. The drilling fluid containing fine cuttings is then poured into a container equipped with a sieve plate with fine meshes for secondary filtration. However, due to the smaller pore size of the fine meshes, the drilling fluid is filtered out of the fine meshes more slowly, resulting in low efficiency in screening out fine cuttings.

[0033] See also Figure 1-5 The utility model provides a technical solution: a rock cuttings separation device for oil and gas resource exploration, comprising a frame, a collecting bucket 1, a sieve plate 2, a rotating barrel 3 and a driving part 4, wherein the collecting bucket 1 is arranged on the frame, the upper end of the collecting bucket 1 is provided with a water inlet, and the lower end is provided with a water outlet, the sieve plate 2 is provided at the upper end of the collecting bucket 1 and covers the water inlet, the upper end of the rotating barrel 3 is open, and the opening is located just below the water outlet, a plurality of sieve holes are distributed on the rotating barrel 3, the rotating barrel 3 is detachably connected to the driving part 4, the driving part 4 is provided on the frame, and the driving part 4 is used to drive the rotating barrel 3 to rotate.

[0034] When using the cuttings separation device for oil and gas resource exploration described in the present invention to separate drilling fluid containing cuttings, a drilling fluid pump (which may be a mud pump model F800) is used to discharge the drilling fluid containing cuttings through a pipeline onto a sieve plate 2. The sieve plate 2 has multiple sieve holes distributed thereon, which retain large cuttings on the sieve plate 2 while allowing fine cuttings to flow downward with the drilling fluid through the sieve holes on the sieve plate 2 and into the collection hopper 1 through the water inlet on the collection hopper 1. Because the opening of the rotating barrel 3 is located directly below the water outlet, the drilling fluid mixed with fine cuttings can flow into the rotating barrel 3 from the water outlet at the bottom of the collection hopper 1. After drilling fluid mixed with fine rock cuttings flows into the rotating barrel 3, it is rotated by the drive unit 4. Due to the multiple sieve holes distributed throughout the rotating barrel 3, the drilling fluid is ejected through the sieve holes under the action of centrifugal force, while the fine rock cuttings are retained within the rotating barrel 3 by the barrier of the rotating barrel 3. After the rotating barrel 3 has drained a certain amount of drilling fluid, the drive unit 4 stops driving the rotating barrel 3. Furthermore, since the rotating barrel 3 is detachably connected to the drive unit 4, the rotating barrel 3 can be removed from the drive unit 4 to facilitate the removal of the fine rock cuttings for analysis. With this structure, the rotating barrel 3 rotates under the drive unit 4, allowing the drilling fluid to be rapidly discharged through the sieve holes under the action of centrifugal force, while the rock cuttings are retained within the rotating barrel 3 by the barrier of the rotating barrel 3, thereby improving the efficiency of screening out fine rock cuttings.

[0035] In this embodiment, the driving unit 4 includes a first rotating shaft 42 and a first motor 41. The first rotating shaft 42 is rotatably connected to the frame. The first rotating shaft 42 is arranged vertically. The first motor 41 is fixedly connected to the frame. The output shaft of the first motor 41 is fixedly connected to the first rotating shaft 42. The rotating barrel 3 is detachably connected to the first rotating shaft 42. The rotating shaft is used to drive the rotating barrel 3 to rotate when rotating. In this embodiment, the first motor 41 can be a motor with model Y160M1-2.

[0036] When the first motor 41 is started, it drives the first rotating shaft 42 to rotate. When the rotating shaft rotates, the rotating shaft drives the rotating barrel 3 to rotate. With this structure, the driving unit 4 can drive the rotating barrel 3 to rotate. Because the rotating barrel 3 is detachably connected to the first rotating shaft 42, the rotating barrel 3 can also be detachably connected to the driving unit 4.

[0037] In this embodiment, the first rotating shaft 42 is arranged vertically, and the frame is provided with a first shaft hole at a position corresponding to the first rotating shaft 42. The first rotating shaft 42 is rotatably engaged in the corresponding first shaft hole. With this structure, the first rotating shaft 42 can be rotatably connected to the frame.

[0038] In this embodiment, the bottom surface of the rotating barrel 3 is recessed upward to form a first slot 31 with a non-circular cross-section. For example, the cross-section of the first slot 31 can be square, triangular or elliptical; the upper end of the rotating shaft protrudes upward to form an insert block 43 that cooperates with the first slot 31.

[0039] By aligning the first slot 31 on the bottom surface of the rotating barrel 3 with the insert block 43 of the rotating shaft, and since the insert block 43 cooperates with the first slot 31, the rotating barrel 3 is moved so that the upper end insert block 43 of the rotating shaft is inserted into the first slot 31 on the bottom surface of the rotating barrel 3, and the rotating barrel 3 can be installed on the rotating shaft; the rotating barrel 3 is moved upward on the rotating shaft so that the slot is disengaged from the insert block 43 upward, and the rotating barrel 3 can be removed from the rotating shaft. With this structure, the rotating barrel 3 can be detachably connected to the first rotating shaft 42; after the rotating barrel 3 is installed on the rotating shaft, when the rotating shaft rotates, the rotating shaft can drive the rotating barrel 3 to rotate under the cooperation of the slot and the insert block 43. With this structure, the rotating shaft can drive the rotating barrel 3 to rotate when it rotates.

[0040] In this embodiment, the edge of the upper end surface of the collecting hopper 1 protrudes upward to form a baffle 21, and the baffle 21 encloses a cavity that cooperates with the sieve plate 2, and the sieve plate 2 is located in the cavity.

[0041] When separating the rock cuttings, since the edge of the upper end surface of the collecting bucket 1 protrudes upward to form a baffle 21, the baffle 21 forms a cavity that cooperates with the screen plate 2, so the drilling fluid pump can discharge the drilling fluid with rock cuttings through the pipeline into the cavity that cooperates with the screen plate 2, so that when the screen plate 2 performs the initial filtration of the drilling fluid, the baffle 21 can block large pieces of rock cuttings in the cavity, thereby reducing the possibility of large pieces of rock cuttings rolling off the edge of the screen plate 2.

[0042] In this embodiment, the sieve plate 2 is movably arranged in the cavity, and a lifting drive component is provided on the collecting bucket 1, and the lifting drive component is used to drive the sieve plate 2 to move up and down.

[0043] When using the cuttings separation device for oil and gas resource exploration described in the present invention to initially separate drilling fluid containing cuttings, the drilling fluid pump discharges the drilling fluid containing cuttings into the cavity via a pipeline, while the lifting drive assembly drives the sieve plate 2 to move up and down. As the sieve plate 2 moves up and down, large pieces of cuttings on the sieve surface are continuously thrown upward, making it easier for fine cuttings to pass through the sieve holes and fall. The up and down movement of the sieve plate 2 continuously changes the relative positional relationship between the cuttings and the sieve holes, allowing cuttings that are easily stuck in the sieve holes to be continuously lifted up, thereby reducing the possibility that some irregularly shaped cuttings will become stuck in the sieve holes and accumulate in large quantities over time, thereby clogging the sieve holes. When the lifting drive assembly drives the sieve plate 2 to move upward, the sieve plate 2 drives the rock chips located on its upper side to move upward. When the lifting drive assembly drives the sieve plate 2 to move downward, the sieve plate 2 moves downward under the action of its own gravity and the downward driving force provided by the lifting drive assembly, so that the downward acceleration of the sieve plate 2 is greater than the acceleration of gravity, and the downward acceleration of the sieve plate 2 is greater than the downward acceleration of the rock chips located on the upper side of the sieve plate 2, so that the rock chips will break away from the sieve plate 2, which can reduce the possibility of the sieve holes of the sieve plate 2 being blocked by rock chips.

[0044] In this embodiment, the lifting drive assembly includes a second rotating shaft 12, a second motor 11, a fixed plate 22, and a spring 23. The second rotating shaft 12 is rotatably connected to the side wall of the collection hopper 1. A ridge is provided on one side of the second rotating shaft 12. The second motor 11 is disposed outside the collection hopper 1 and is fixed to the frame. The output shaft of the second motor 11 is fixedly connected to the second rotating shaft 12. The fixed plate 22 is disposed above the sieve plate 2 and is fixedly connected to the inner side wall of the baffle 21. One end of the spring 23 is connected to the fixed plate 22, and the other end of the spring 23 is connected to the sieve plate 2. In this embodiment, the second motor 11 can be a motor model Y160M1-2.

[0045] When using the rock cuttings separation device for oil and gas resource exploration of the present invention to perform initial separation of drilling fluid containing rock cuttings, the second motor 11 can be used to drive the second rotating shaft 12 to rotate. When the convex strips can rotate along with the second rotating shaft 12, the convex strips can continuously and cyclically press the sieve plate 2 upward and downwardly detach from the sieve plate 2 during the process of the convex strips pressing the sieve plate 2 upward, and the sieve plate 2 can be raised during the process of the sieve plate 2 rising. During the process of the convex strips detaching downward from the sieve plate 2, the sieve plate 2 can move downward under the action of its own weight and the elastic force of the spring 23. With this structure, the lifting drive assembly can drive the sieve plate 2 to move up and down.

[0046] During the downward movement of the sieve plate 2, in addition to being affected by its own gravity, the sieve plate 2 will also receive the downward elastic force provided by the spring 23. The elastic force of the spring 23 is the downward driving force provided by the lifting drive assembly of the sieve plate 2. Under the action of its own gravity and the elastic force provided by the spring 23, the acceleration of the downward movement of the sieve plate 2 can be greater than the acceleration of gravity.

[0047] In this embodiment, the second motor 11 is arranged outside the collecting bucket 1, and the second motor 11 is fixed on the frame. The second motor 11 is arranged outside the collecting bucket 1, which can reduce the possibility of the second motor 11 being wetted by water during the separation process and can reduce the possibility of the second motor 11 being damaged.

[0048] In this embodiment, a second shaft hole is provided on the side wall of the collecting hopper at a position corresponding to the second rotating shaft 12. The second rotating shaft 12 is rotatably engaged with the corresponding second shaft hole. With this structure, the second rotating shaft 12 can be rotatably connected to the frame.

[0049] In this embodiment, the frame includes a frame body, a mounting portion and a supporting portion. The mounting portion can be movably arranged on the frame body up and down. The driving portion 4 is arranged on the mounting portion. The collecting bucket 1 is rotatably connected to a rotating ring 7. The rotating ring 7 is arranged along the edge of the water outlet. The lower end surface of the rotating ring 7 protrudes downward to form a first insertion rod 14; a second slot 32 that cooperates with the first insertion rod 14 is provided on the top wall of the rotating barrel 3, and the supporting portion is used to support the mounting portion after the first insertion rod 14 is inserted into the second slot 32.

[0050] Before using the rock cuttings separation device for oil and gas resource exploration described in the present invention to separate drilling fluid containing rock cuttings, the mounting portion can be moved downward, and the mounting portion drives the driving portion 4 downward, and the rotating barrel 3 is installed on the driving portion 4. The mounting portion is pushed upward, and the first insertion rod 14 on the rotating ring 7 is aligned with the second slot 32 provided on the top wall of the rotating barrel 3. After the first insertion rod 14 is inserted into the second slot 32, the mounting portion is supported by the support portion. The rotating barrel 3 is connected to the rotating ring 7 by inserting the first insertion rod 14 into the second slot 32. During the rotation of the rotating barrel 3, the first insertion rod 14 limits the shaking of the upper end of the rotating barrel 3 to a certain extent. With this structure, during the rotation of the rotating barrel 3, the rotating ring 7 can limit the amplitude of the shaking generated by the rotating barrel 3 during rotation, thereby increasing the stability of the rotating barrel 3.

[0051] After using the rock cuttings separation device for oil and gas resource exploration described in the present invention to separate drilling fluid containing rock cuttings, the support of the supporting portion on the mounting portion is released, and the mounting portion is moved downward to disengage the second slot 32 from the first insertion rod 14, so that the rotating barrel 3 is disengaged from the first insertion rod 14. After the mounting portion and the driving portion 4 move downward a certain distance, the rotating barrel 3 can be removed from the driving portion 4.

[0052] In this embodiment, the rotating ring 7 includes a circular ring 72 and two retaining rings 71. The circular ring 72 is located within the water outlet and engages with the water outlet. The two retaining rings 71 are respectively fixed to the upper and lower ends of the circular ring 72. The two retaining rings 71 are arranged coaxially with the circular ring 72. The two retaining rings 71 respectively abut the upper and lower side surfaces of the bottom plate of the collection hopper 1. The first insertion rod 14 is formed by protruding downward from the lower side surface of the retaining ring 71 located at the lower end of the circular ring 72. With this structure, the rotating ring 7 can be rotatably connected to the collection hopper 1.

[0053] In this embodiment, the frame includes two support plates 5, and the two support plates 5 are each provided with a first strip hole 51. The two first strip holes 51 are opposite to each other, and the first strip holes 51 are arranged vertically.

[0054] The mounting portion includes a connecting plate 6 and a slider 61. The connecting plate 6 is provided between the two support plates 5. The sliders 61 are two pieces, and the two sliders 61 are provided at both ends of the connecting plate 6. The two sliders 61 are located in the two first strip-shaped holes 51 in a one-to-one correspondence.

[0055] The driving portion 4 is provided on the connecting plate 6 ; the collecting hopper 1 is fixedly connected to the two supporting plates 5 ; the supporting portion is used to support the two sliding blocks 61 after the first insertion rod 14 is inserted into the second slot 32 .

[0056] The two first strip holes 51 on the frame are opposite to each other and arranged vertically. The two sliders 61 are matched in the two first strip holes 51 one by one. The two sliders 61 can slide up and down in the two first strip holes 51. With this structure, the mounting part can move up and down on the frame.

[0057] Since the two sliding blocks 61 are located in the two first strip holes 51 in a one-to-one correspondence, the connecting plate 6 can move up and down on the two supporting plates 5, and the mounting portion can be movably arranged on the frame.

[0058] After the first insertion rod 14 is aligned with the second slot 32, when the two sliders 61 slide to the top of the first strip hole 51, the first insertion rod 14 can be inserted into the second slot 32, and then the two sliders 61 are supported and limited by the support part. With this structure, the support part can be used to support the mounting part after the first insertion rod 14 is inserted into the second slot 32.

[0059] In this embodiment, the first axial hole is arranged on the connecting plate 6, the first shaft of the driving part 4 is rotatably engaged in the corresponding first axial hole, the first motor 41 is fixed on the connecting plate 6, and the output shaft of the first motor 41 is fixedly connected to the first shaft. With this structure, the driving part 4 can be arranged on the mounting part.

[0060] In this embodiment, the support portion includes two support components, which are arranged on the two support plates 5 in a one-to-one correspondence. The two support components are used to support the two sliders 61 in a one-to-one correspondence after the first insertion rod 14 is inserted into the second slot 32.

[0061] The support assembly includes a fixed block 511 and a second insertion rod 512. There are two fixed blocks 511. Both fixed blocks 511 are fixed on the support plate 5. The two fixed blocks 511 are respectively located on both sides of the first strip hole 51. Both fixed blocks 511 are provided with a through hole 513 adapted to the second insertion rod 512. The through holes 513 on the two fixed blocks 511 are opposite to each other. One end of the second insertion rod 512 is used to pass through one through hole 513 and then be inserted into the other through hole 513.

[0062] After the first insertion rod 14 is inserted into the first slot 31, the slider 61 is positioned above the through-hole 513. One end of the second insertion rod 512 is passed through one through-hole 513 and then inserted into the other through-hole 513. The second insertion rod 512 then supports the corresponding slider 61. With this structure, the support assembly can support the corresponding slider 61 after the first insertion rod 14 is inserted into the second slot 32.

[0063] Pulling the first insertion rod 14 out of the two through holes 513 can release the support of the support rod on the corresponding slider 61, that is, the support of the two support components on the corresponding slider 61 can be released, that is, the support of the support part on the slider 61 can be released.

[0064] In this embodiment, the two support plates 5 are further provided with second strip holes 52 along the horizontal direction. The two second strip holes 52 correspond one-to-one to the two first strip holes 51. The inner ends of the second strip holes 52 are connected to the bottom ends of the corresponding first strip holes 51. The slider 61 cooperates with the second strip holes 52. When the slider 61 slides to the outer end of the second strip hole 52, the rotating barrel 3 is located on the outside of the edge of the collecting bucket 1.

[0065] After the drilling fluid containing cuttings is separated using the cuttings separation device for oil and gas resource exploration of the present invention, since the inner ends of the second strip holes 52 are connected to the bottom ends of the corresponding first strip holes 51, the connecting plate 6 can be lowered and then pulled outward from the edge of the collection bucket 1 through the second strip holes 52, thereby moving the rotating barrel 3 to the outside of the edge of the collection bucket 1. After the drilling fluid containing cuttings is separated and filtered, when the rotating barrel 3 is removed from the driving unit 4, it will not be blocked by the collection bucket 1, making it more convenient to remove the rotating barrel 3 from the driving unit 4.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
