Description

Technical Field

[0001] The utility model relates to the technical field of drilling processing, in particular to a forklift system for drilling cuttings disposal. Background Art

[0002] Drilling fluid refers to the general term for various circulating fluids that meet the needs of drilling work with their multiple functions during oil and gas drilling. Depending on the continuous phase, drilling methods are divided into water-based drilling and oil-based drilling. A large amount of rock cuttings are usually generated during the drilling process. The rock cuttings are mixed with drilling fluid and transported to the ground. After being transported to the ground, the drilling cuttings usually need to be separated and processed. After separation, the liquid and solid substances in the drilling cuttings are separated from each other and recycled separately. The separated solid drilling cuttings usually need to be transported to the corresponding location and processed centrally. In order to improve the processing efficiency of solid drilling cuttings, the drilling cuttings are usually transported and processed by transportation equipment.

[0003] For example, the patent document with publication number CN204642769U discloses a cuttings collection and transportation tank, which includes a tank body and a sludge pump. The bottom of the tank body is a sloped surface and a horizontal surface at a certain angle, with a forklift insertion pipe on the upper part, and splash guards and movable covers on the three sides of the top; the sludge pump motor is fixed on the upper part of the tank body, and the water inlet is located at a horizontal position at the bottom of the tank body. The above technical solution is mainly used for the collection and transportation of cuttings, sludge, and mud at the drilling site, and is more suitable for the collection and transportation of cuttings and mud at the bottom of conical tanks and various circulation tanks.

[0004] Although the above technical solution can realize the transfer and processing of drill cuttings, the above technical solution only transports the drill cuttings by forklift. After the drill cuttings are transported to the designated location, it is necessary to flip the tank body by other auxiliary devices so that the drill cuttings can be unloaded from the tank body. As a result, during the transportation of the drill cuttings, the tank body needs to complete the transportation and unloading process of the drill cuttings with the assistance of multiple devices, resulting in low transportation efficiency of the drill cuttings. Utility Model Content

This makes it easy to unload the loading part 2, while ensuring the structural strength of each area of ​​the loading part 2, improving the stability of the loading part 2 after containing drilling cuttings, and improving the service life of the loading part 2.

[0025] A first connection hole 204 and a second connection hole 205 are provided at the bottom of the loading part 2.

[0032] When the drilling cuttings are transported, the loading part 2 is placed at the discharge port of the drilling cuttings processing device, so that the drilling cuttings processed by the drilling cuttings processing device are placed in the loading part 2. After the preset drilling cuttings are placed in the loading part 2, the forklift body 1 is controlled so that the fork 101 on the forklift body 1 extends into the first connection hole 204 or the second connection hole 205, and drives the loading part 2 to move to the corresponding position. When the drilling cuttings in the loading part 2 are unloaded, the loading part 2 is lifted upward by moving the loading part 2 along the door frame 102, and the loading part 2 is rotated by driving the fork 101 through the rotating part 3, so that the drilling cuttings in the loading part 2 slide out of the loading part 2, and the unloading of the loading part 2 is completed.

Moreover, when the forklift body 1 is connected to the loading part 2, it is only necessary to connect the fork 101 to the first connection hole 204 or the second connection hole 205, thereby improving the convenience of the connection of the forklift body 1, thereby enabling the drilling cuttings to be conveniently transported and unloaded in different transport scenarios, thereby improving the flexibility of drilling cuttings transport. Furthermore, by providing a rotating part 3 between the fork 101 and the mast 102, when unloading the drilling cuttings in the loading part 2, the loading part 2 can be directly flipped and unloaded by the forklift body 1 during transportation, without the need for unloading operations through other devices, thereby improving the efficiency of drilling cuttings transport and unloading.
