Description

Technical Field

[0002] Shale gas is a very important unconventional natural gas resource extracted from shale layers. Its formation and enrichment have their own unique characteristics. It is often distributed in thick and widely distributed shale source rock formations in basins. Shale oil and gas resources are formed in shale rich in organic matter. The low permeability of shale greatly inhibits the migration of hydrocarbons (oil or gas) to more permeable reservoir rocks. Shale is both an oil-generating rock and an oil-storing rock.

[0003] In the prior art, for example, Chinese patent number: CN112147688B discloses a reservoir oil and gas identification method and device, the method comprising: constructing a sandstone reservoir oil and gas identification factor calculation formula for the target well according to the well logging curve data of the target layer section in the target well; obtaining the sandstone reservoir oil and gas identification factor curve corresponding to the target layer section in the target well based on the well logging interpretation result data of the target layer section in the target well and the sandstone reservoir oil and gas identification factor calculation formula; using the sandstone reservoir oil and gas identification factor curve to identify the oil and gas distribution range of the target layer section in the target well. This application can effectively eliminate the interference of aquifers on reservoir oil and gas identification, and can effectively improve the accuracy and reliability of well logging interpretation, thereby effectively improving the accuracy and reliability of reservoir oil and gas identification.

[0032] In this embodiment, when using the device to detect and identify shale oil and gas reservoirs, first take 0.5m 3The shale sample is then put into the crushing box 1 and the double-axis motor 402 is started. After the double-axis motor 402 is started, the two first pulleys 403 are driven to rotate. During the rotation of the two first pulleys 403, the two second pulleys 405 are driven to rotate through the first transmission belt 404.

[0034] In this embodiment, when the shale after secondary crushing falls on the filter plate 501, the vibration motor 505 is started. At this time, the filter plate 501 will shake under the action of the vibration motor 505, thereby lifting the broken shale above. The broken shale can be effectively separated from the oil during the repeated lifting process and can slide smoothly to a lower place. The connecting column 502 and the connecting block 504 at the bottom of the filter plate 501 are connected by a spring 503, so it has the effect of intensifying the shaking amplitude, further ensuring the discharge of shale, and at the same time avoiding the clogging of the filter holes on the surface of the filter plate 501, which is highly practical.

A second weighing plate 708 is embedded in the top of the receiving plate 707. A U-shaped enclosure 709 is fixedly connected to the top of the receiving plate 707 near the edge. A rotating shaft 710 is fixedly connected to the outer surfaces of the front and rear sides of the receiving plate 707 near the right edge. The outer surfaces of the two rotating shafts 710 are rotatably connected to a third rotating seat 711, and the third rotating seat 711 is welded to the top of the crushing box 1 near the left edge.

[0036] 706, and the second rotating head 705 rotates between the inner wall of the second rotating seat 706. The shale sample is placed in the crushing box 1 for identification.

[0037] The effect and working principle of the whole mechanism are as follows: when using this device to detect and identify shale oil and gas reservoirs, first take 0.5m 3The shale sample is then put into the crushing box 1 and the double-axis motor 402 is started. After the double-axis motor 402 is started, it will drive the two first pulleys 403 to rotate. During the rotation of the two first pulleys 403, the two second pulleys 405 will be driven to rotate through the first transmission belt 404. At this time, the third pulley 406 on the surface of the second pulley 405 will synchronously drive the fourth pulley 408 to rotate slowly through the second transmission belt 407. When the two second pulleys 405 rotate, the two eccentric wheels 301 inside the crushing box 1 will be driven to rotate synchronously. When the two eccentric wheels 301 rotate, the top of the connecting plate 303 will be driven to swing through the first connecting shaft 302. In this process, the bottom of the connecting plate 303 is restricted by the first connecting rod 304 and will shake within the moving range. , and at the same time, the second connecting rod 306 drives the back bar 307 to repeatedly shake within a certain range, so that the inclined first tooth plate 309 follows the shaking, and the shale sample put into the crushing box 1 will be gradually broken into small pieces between the static second tooth plate 310 and the shaking first tooth plate 309, and then fall onto the guide plate 205 inside the separation box 201 through the gap under the first tooth plate 309 and the second tooth plate 310, and then fall to the position between the two rolling rollers 202 under the action of gravity, and the fourth pulley 408 will synchronously drive one of the rolling rollers 202 to rotate during the slow rotation, and at this time, the rolling roller 202 synchronously drives one of the transmission gears 203 to rotate, so that the other transmission gear 203 synchronously rotates in the opposite direction , and then drive another rolling roller 202 to rotate. The two counter-rotating rolling rollers 202 will crush the shale fragments passing through into fragments with a diameter of less than 1 cm. The oil in the internal reservoir of the crushed shale will be separated from the shale fragments and fall onto the inclined filter plate 501 below. The oil will pass through the filter plate 501 and flow into the collection tank 207 from the drainage pipe 206. The shale fragments will slide downward under the action of gravity and enter the pad 607 inside the collection box 601 through the transfer channel 204. Then, the electric push rod 605 is started to push the first weighing plate 606 up and lift up the pad 607, i.e., the shale fragments. The shale weight can be obtained by calculation. At the same time, the oil in the collection tank 207 can be weighed to obtain the shale reservoir in the area. The oil content is then determined by controlling the electric push rod 605 to drive the first weighing plate 606 to descend and form a non-fitting state with the pad 607. The pad 607 will be completely supported by the rectangular support block 604. At this time, the first hydraulic cylinder 602 is started to drive the pressure plate 603 to descend and press it into a regular shape, then it is taken out from the box door to measure its volume. At the same time, the oil capacity is obtained according to the scale on the collection tank 207. The porosity and oil and gas proportion in the shale reservoir can be obtained through calculation. The overall operation is convenient, and the shale oil and gas reservoir identification operation can be completed without high technical support. The overall cost is low. In addition, when the shale after secondary crushing falls on the filter plate 501, the vibration motor 505 is started. At this time, the filter plate 501 will shake under the action of the vibration motor 505.Thus, the crushed shale above is lifted up. In the process of repeated lifting, the crushed shale can be effectively separated from the oil and can slide smoothly to the lower place. The connecting column 502 and the connecting block 504 at the bottom of the filter plate 501 are connected by the spring 503, so it has the effect of intensifying the shaking amplitude, further ensuring the discharge of shale, and avoiding the clogging of the filter holes on the surface of the filter plate 501, which is highly practical. At the same time, when the shale sample is put in, it is directly transported to the receiving plate 707 by the equipment. At this time, the second weighing plate 708 embedded in the top of the receiving plate 707 will detect the weight of the shale sample of a fixed volume, and the data can be improved by combining the subsequent crushed rock and oil weight. Then the second hydraulic cylinder 704 is started to generate an upward thrust. At this time, the rotating shaft 710 on the surface of the receiving plate 707 will rotate between the third rotating seat 711 and make the receiving plate 707 flip over to the top of the crushing box 1 as a whole, thereby playing the effect of putting the shale sample into the crushing box 1 for identification. It does not require manual feeding and has the effect of improving the data, and the use effect is good.
