Description

Technical Field

[0001] This application relates to the field of petroleum geological logging technology, and in particular to a petroleum geological logging cuttings retrieval and washing device. Background Technology

[0002] During oil drilling, the high-speed flowing mud in the drill string carries drilling cuttings from the well to the surface. The cuttings are then filtered out by a mud vibrating screen. For a long time, the cuttings were collected manually at the construction site. The cuttings with drilling mud adhering to their surface were then washed with water and taken back to the geological room for geological analysis.

[0003] However, traditional oilfield logging cuttings washing equipment generally uses a flushing method to clean the cuttings. Some stubborn stains are difficult to clean. Furthermore, the wastewater generated by flushing is usually a mixture of clay solution, oil, and chemicals, which cannot be directly recycled or reused. Therefore, it consumes a lot of water in actual operation, resulting in water waste and increased operating costs.

[0004] Therefore, a cuttings retrieval device for petroleum geological logging was proposed. Utility Model Content

[0005] This application provides a petroleum geological logging cuttings washing device to solve the problems of some strongly adhering stains being difficult to clean and the inconvenience of purifying and reusing the washed water.

[0006] This application provides a cuttings retrieval device for petroleum geological logging, including a conveyor frame. A flushing chamber is fixedly installed on the top surface of the conveyor frame. A flushing water pipe is fixedly installed on the inner top wall of the flushing chamber. Several flushing nozzles are installed through the bottom surface of the flushing water pipe. An A-servo motor is fixedly installed on one side of the outer surface of the flushing chamber. A brush roller is fixedly installed at the output end of the A-servo motor. A water storage tank is installed through the bottom surface of the conveyor frame. A slot is opened on the top surface of the water storage tank. A filter box is inserted into the slot. The bottom of the filter box is an activated carbon plate. A quartz sand plate is provided above the activated carbon plate inside the filter box.

[0007] Preferably, a B servo motor is fixedly installed on one edge of the conveyor frame, and a rotating roller is fixedly installed at the output end of the B servo motor. A perforated conveyor belt is sleeved on the surface of the rotating roller, and the perforated conveyor belt is used to convey rock cuttings.

[0008] Preferably, a water pump is fixedly installed on the outer surface of the water storage tank, and a delivery pipe is provided through the output end of the water pump. One end of the delivery pipe is connected to the flushing water pipe, and the delivery pipe is used to supply water to the flushing water pipe.

[0009] Preferably, a driven roller is sleeved on the side of the hollow conveyor belt away from the rotating roller. The driven roller is rotatably mounted on the inner wall of the conveyor frame, which facilitates the rotation of the hollow conveyor belt.

[0010] Preferably, a water pump is provided through the input end of the water pump, and one end of the water pump is provided through the inside of the water storage tank, so that the water pump can easily draw water from the inside of the water storage tank.

[0011] Preferably, a handle is fixedly installed on one side of the filter box, and the surface of the handle is covered with an anti-slip sleeve. The handle is used to open and close the filter box.

[0012] Preferably, waterproof curtains are fixedly installed on both sides of the rinsing chamber, and a drain pipe is installed through the bottom of the outer surface of the water storage tank, with the waterproof curtains preventing water from splashing.

[0013] Beneficial effects:

[0014] Considering the difficulty in cleaning stubborn stains and the inconvenience of purifying and reusing the rinsed water, the water pump is turned on to extract water from the storage tank and deliver it to the rinsing pipe. The water then washes away the rock debris through the rinsing nozzles. The rinsed water falls into the filter box via a perforated conveyor belt, where quartz sand and activated carbon plates filter and purify the water. The clean water then flows back into the storage tank, achieving the effect of reusing water resources and avoiding water waste.

[0015] During the rinsing process, servo motor A drives the brush roller to rotate, brushing the rock debris and loosening and removing some of the more stubborn stains, thus preventing residue and making the cleaning more thorough and effective.

[0033] In this process, the water pump 6 is turned on to extract water from the water storage tank 14 and deliver it to the flushing water pipe 10 through the delivery pipe 7. The water is then used to flush the rock debris through the flushing nozzle 11. The flushed water falls into the filter box 15 through the perforated conveyor belt 5 and is filtered and purified by the quartz sand plate 17 and the activated carbon plate 16 in sequence before flowing back into the water storage tank 14. This process can then be used for flushing again, achieving the effect of water resource reuse and avoiding water waste.

[0034] During the rinsing process, servo motor 12 drives the brush roller 13 to rotate, brushing the rock debris, which loosens and removes some heavily adhered stains, preventing residue and making the cleaning more thorough and clean, thus improving the cleaning effect.

[0035] A B servo motor 3 is fixedly installed on one side edge of the conveyor frame 1. A rotating roller 4 is fixedly installed at the output end of the B servo motor 3. A hollow conveyor belt 5 is sleeved on the surface of the rotating roller 4.

[0036] Among them, servo motor 3 drives the rotating roller 4 to rotate, which in turn drives the perforated conveyor belt 5 to rotate, automatically conveying rock cuttings.

[0037] A water pump 6 is fixedly installed on the outer surface of the water storage tank 14. A delivery pipe 7 is provided through the output end of the water pump 6, and one end of the delivery pipe 7 is connected to the flushing water pipe 10.

[0038] Among them, the water pump 6 is turned on to draw water from the water storage tank 14 and deliver it to the flushing water pipe 10 through the delivery pipe 7.

[0039] A driven roller 8 is sleeved on the side of the hollow conveyor belt 5 away from the rotating roller 4. The driven roller 8 is rotatably mounted on the inner wall of the conveyor frame 1.

[0040] Among them, the driven roller 8 rotates following the perforated conveyor belt 5.

[0042] Among them, the water pump 6 is turned on, and the water inside the water storage tank 14 is drawn out through the water pumping pipe 9.

[0043] A handle 18 is fixedly installed on one side of the filter box 15, and an anti-slip sleeve is fitted onto the surface of the handle 18.

[0044] The handle 18 is used to open and close the filter box 15, which is used to filter and collect residues and solid impurities in the sewage.

[0045] Waterproof curtains 19 are fixedly installed on both sides of the flushing chamber 2, and a drain pipe is installed through the bottom of the outer surface of the water storage tank 14.

[0046] Among them, the waterproof curtain 19 prevents water from splashing.

[0047] Working principle: When this petroleum geological logging cuttings washing device is in use, the B servo motor 3 drives the rotating roller 4 to rotate, which in turn drives the perforated conveyor belt 5 to rotate, automatically conveying the cuttings. The water pump 6 is turned on to extract the water source inside the water storage tank 14 and deliver it to the flushing water pipe 10 through the conveying pipe 7, and then the cuttings are washed through the flushing nozzle 11.
