Description

Technical Field

[0001] The utility model relates to the technical field of rock cuttings drying, in particular to a rock cuttings drying device. Background Art

[0002] In the exploration of oil and gas resources, real-time and accurate identification of stratum lithology is of great significance for timely discovery of oil and gas layers. In the actual drilling process, since the cuttings are carried back to the ground with the drilling fluid, the surface of the cuttings is attached with drilling fluid dirt. Therefore, the cuttings after collection need to be cleaned and dried first, and then the staff will select samples for geological observation, description, naming, and establishment of lithology profiles to accurately determine the reservoir location and provide reference materials for formation evaluation and reservoir description.

[0003] In the prior art, the cleaned rock cuttings are mostly dried by natural sun drying or electric oven baking. Although both methods can obtain dry rock cuttings, the natural sun drying method is easily affected by the weather, especially in a low temperature environment, and the sun drying takes a long time, which cannot match the speed required for rock cutting description during the rapid drilling process on site.

[0004] However, when using an electric oven for baking, the interior of the electric oven is a sealed space that cannot exchange airflow with the outside world. Therefore, during the baking process, the steam generated by the wet rock cuttings after being baked in the electric oven will fill the interior of the electric oven. In this case, it is necessary to bake and evaporate all the steam before obtaining dry rock cuttings, resulting in a long drying time. Therefore, the demand for providing rock cuttings in real time cannot be met.

[0005] In addition, using an electric oven to bake the cuttings can easily cause the light oil in the cuttings to volatilize along with the water vapor filling the feeding chamber, resulting in the loss of original oil content information, which can cause misjudgment and affect the accuracy of subsequent analysis results of the cuttings.

[0011] In one embodiment, the heating mechanism includes a placement portion connected to the bottom of the inner box, a heating portion arranged above the placement portion and extending axially upward, and an open top, and a plurality of heating holes are distributed on the heating portion along the axial direction.

[0012] In one embodiment, the upper end surface of the inner box is provided with at least one second fan with an air outlet facing the heating mechanism, and the second fan is used to generate a downward force on the gas heated by the heating mechanism, squeezing the gas to diffuse in all directions.

[0013] In one embodiment, the second fan is arranged corresponding to the top of the heating mechanism, and the air outlet of the second fan is located at the top opening of the heating mechanism.

[0014] In one embodiment, the outer shell includes an outer box body which is hollow inside and has an opening on the top, and a ventilation plate arranged at the opening of the outer box body, wherein the ventilation plate is provided with at least one exhaust hole which is connected with the inside of the outer box body.

[0035] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a cuttings drying device of the utility model in conjunction with the accompanying drawings.

[0036] For convenience, the direction extending along the length of the outer box is referred to as "axial" or similar terms, the direction from the bottom toward the top of the outer box is referred to as "upward" or similar terms, and the direction from the top toward the bottom of the outer box is referred to as "downward" or similar terms.

[0037] like Figure 1 As shown, an embodiment of the present utility model provides a rock cutting drying device 100, including an outer box 2, wherein the outer box 2 is configured in any shape that is convenient for stable placement. Figure 6 As shown, the outer box body 2 is configured as a circular columnar structure.

[0038] like Figure 6As shown, in the illustrated embodiment, the outer box body 2 is composed of a bottom plate 23 and a side plate 22 extending upward along the bottom plate 23. A first mounting groove 21 is formed on the side plate 22, and a sealing door 9 is provided at the first mounting groove 21. The sealing door 9 is used to seal the outer box body 2, so that a sealed space is formed inside the outer box body 2.

[0039] In one embodiment, Figure 6 As shown, the outer box body 2 further includes a ventilation plate 1 disposed on the top of the outer box body 2, and a plurality of exhaust holes 11 are formed on the ventilation plate 1. A first mounting hole 24 is formed on the bottom plate 23 at a position corresponding to each exhaust hole 11, and a first fan 241 with an air outlet facing the top of the outer box body is disposed in the first mounting hole 24.

[0040] In this configuration, the first fan 241 is started, and the first fan 241 can generate an upward force on the airflow inside the outer box body 2 , so that the airflow inside the outer box body 2 continues to move upward until it is discharged from the exhaust hole 11 .

[0041] In one embodiment, Figure 2 As shown, the inner box 8 is rotatably arranged inside the outer box 2. Figure 4 As shown, the inner box body 8 includes a base 83 rotatably connected to the bottom of the outer box body 2, and a side wall extending upward along the base 83, wherein the side walls are enclosed to form a hollow opening shape. The outer side wall of the inner box body 8 is evenly provided with a plurality of second grooves 81 along the circumferential direction. In this way, the plurality of second grooves 81 and the end face of the outer side wall of the inner box body 8 form two concentric circles with different diameters. Specifically, the end face of the inner box body 8 is configured in a gear shape.

[0042] In one embodiment, Figure 4 As shown, the surface of each second groove 81 is provided with a plurality of through holes 82 connected to the hollow area inside the inner box 8. In the illustrated embodiment, the plurality of through holes 82 are evenly distributed along the inner box 8 in the axial direction. In this way, the internal cavity of the inner box 8 is connected to the outer box 2 through the through holes 82. In this arrangement, an airflow channel is formed and an airflow movement path is formed.

[0043] In one embodiment, Figure 3 As shown, the side of each second groove 81 opened on the surface of the inner box 8 is provided with a mounting mechanism 4, and the mounting mechanism 4 is detachably connected to a containing mechanism, and the containing mechanism is used to contain the rock chips to be dried. The containing mechanism is configured to be any shape that is convenient for accommodating the rock chips. In the illustrated embodiment, the shape of the containing mechanism is adapted to the second groove 81.

[0044] In one embodiment, the rock cuttings drying device 100 further includes a heating mechanism 10 disposed inside the inner box 8, and the heating mechanism 10 is used to provide heat to dry the rock cuttings placed in the containing mechanism.

[0045] In this way, when in use, unprocessed rock cuttings are placed in the containing mechanism, and the heating mechanism 10 and the first fan 241 of the outer box are started at the same time. At this time, the heat generated by the heating mechanism 10 diffuses to the surroundings. In this way, the wet rock cuttings placed in the containing mechanism can be dried.

[0046] During this process, the moisture precipitated from the cuttings is heated by the heating mechanism 10, so that the moist high-temperature gas fills the outer box 2 and the inner box 8. Since the moist, high-temperature gas in the inner box 8 is close to the heating mechanism 10, the moist, high-temperature gas in the inner box 8 can be dried. The moist, high-temperature gas filled in the outer box 2 is subjected to the upward force applied by the first fan 241, so that it continues to move upward until it is discharged through the exhaust hole 11.

[0047] In the present utility model, if Figure 2 As shown, the containing mechanism includes two mounting plates 5 arranged opposite to each other, the inner sides of the mounting plates 5 arranged opposite to each other jointly form a second mounting groove 53, a receiving box 6 is detachably arranged in the second mounting groove 53, and the receiving box 6 forms a space for receiving the rock cuttings to be processed.

[0048] According to a preferred embodiment of the present invention, Figure 8 As shown, a plurality of slide grooves 54 are arranged on both sides of the second installation groove 53, and first sliders 61 matching with the slide grooves 54 are arranged on both sides of the receiving box 6. In this way, the receiving box 6 can be detachably arranged inside the second installation groove 53.

[0049] like Figure 8 As shown, the containing mechanism further includes a first groove 51 disposed on the upper portion of the mounting plate 5, and the shape of the first groove 51 is adapted to the mounting mechanism 4. A mounting column 52 is correspondingly disposed inside the mounting groove 51, and the mounting column 52 is detachably connected to the mounting mechanism 4.

[0050] In one embodiment, Figure 8 As shown, the second mounting groove 53 is provided with an air guide groove 7, and the air guide groove 7 and the receiving box 6 together form an exhaust channel 55. In this way, the air flow can flow along the exhaust channel 55, and the air flow movement speed is accelerated.

[0051] In one embodiment, Fig.10 , Fig.11As shown, the storage box 6 includes a bottom wall portion 64 and a side wall portion 63 extending upward along the bottom wall portion 64. The side wall portion 63 is enclosed to form a box body having a rock debris storage area. Among them, a plurality of first ventilation holes 641 are provided on the bottom wall portion 64. In the illustrated embodiment, the plurality of first ventilation holes 641 are evenly distributed on the bottom wall portion 64. The side wall portion 63 begins to have a plurality of second ventilation holes 632. In the illustrated embodiment, the plurality of second ventilation holes 632 are evenly distributed on the storage box side plate 63.

[0052] According to a preferred embodiment of the present invention, Fig.10 As shown, the receiving box 6 further includes a top cover 62 for sealing the opening of the receiving box 6, and the top cover 62 has second sliders 621 extending outwardly on both sides. A second slide groove 631 is provided at a position of the side wall portion 63 corresponding to the second slider 621. In this way, the top cover 62 can slide along the path defined by the second slide groove 631, so as to facilitate the filling of rock cuttings.

[0053] In one embodiment, Figure 5 As shown, the heating mechanism 10 is configured to have any shape with a heating function. In the present embodiment, the heating mechanism 10 is configured to be a truncated cone structure with a trapezoidal cross section. At the same time, the heating mechanism 10 can also be configured to be cylindrical, square, rectangular or other shapes. Among them, the heating mechanism 10 includes a placement portion 103, and the placement portion 103 is configured to be in a plane shape for being stably arranged in the inner box 8. The heating mechanism 10 also includes a heating portion extending upward along the placement portion 103, and an open top 101. Among them, a plurality of heating holes 102 are provided on the heating portion. In this way, heat can be evenly diffused from the heating mechanism 10 to the surroundings, thereby drying and heating the wet rock cuttings.

[0054] According to a preferred embodiment of the present invention, Figure 1 As shown, a top cover 3 is provided at the opening of the inner box 8. A second mounting hole 31 is provided on the top cover 3, and a second fan (not shown in the figure) with an air outlet facing the placement portion 103 is provided in the second mounting hole 31, and the second fan corresponds to the top 101 of the heating mechanism 10. In this way, when the heating mechanism 10 and the second fan are started, the second fan can generate a downward force on the airflow heated by the heating mechanism 10, so that the hot airflow can be evenly diffused to the surroundings through the heating hole 102. Under this setting mode, the speed of the hot airflow diffusing to the surroundings is accelerated, and the efficiency of rock cuttings drying is improved.

[0055] The operation of the cuttings drying device 100 according to the present invention is as follows.

[0056] First, the sealing door 9 is opened, and the rock chips to be dried are placed in each receiving box 6. At the same time, the inner box 8 is rotated to place the rock chips to be dried in the receiving boxes 6 arranged along the circumference of the inner box 8. When the rock chips are placed, the sealing door 9 is closed, so that the interior of the rock chip drying device 100 forms a closed chamber as a whole.

[0057] Next, the heating mechanism 10, the second fan and the first fan 241 are started. In this process, the heating mechanism 10 heats the gas in the inner box 8, thereby generating a high-temperature airflow. At the same time, the second fan continuously exerts a downward force on the high-temperature airflow heated by the heating mechanism 10, so that the high-temperature airflow continuously diffuses and moves around, and is transmitted to the surface of the containing box 6 along the through hole 82 connected to the inside of the inner box 8.

[0058] When the high-temperature airflow contacts the plurality of containing boxes 6 , the high-temperature airflow enters into the containing boxes 6 along the plurality of second ventilation holes 632 opened on the side of the containing boxes 6 , thereby drying the wet rock chips contained in the plurality of containing boxes 6 .

[0059] In this process, after the high-temperature airflow contacts the rock chips and dries the rock chips, the container box 6 will be filled with high-temperature, humid airflow. Since the density of the high-temperature, humid airflow is less than that of the outside air, the high-temperature, humid airflow in the container box 6 will continue to move upward. After moving to the air guide groove 7, it is affected by the high-temperature airflow that continues to diffuse to the surroundings, so the high-temperature, humid airflow will continue to move to the surroundings with the high-temperature airflow, thereby accelerating the airflow speed.

[0060] When the airflow moves to the outer box 2, the airflow is subjected to the upward force exerted by the first fan 241, so that the airflow continues to move upward until it is discharged from the exhaust hole 11. This cycle is repeated to complete the drying of the cuttings.

[0061] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
