The invention provides a circulating tank and a drilling fluid circulating tank automatic induction washing method, and belongs to the technical field of drilling engineering circulating system machinery. The circulating tank is characterized by comprising a tank body, rotary spraying guns, sand setting inductors, a fluid supply pump, an electronic control valve and a control module; the fluid supply pump provides spraying fluid for the rotary spraying guns; the electronic control valve is used for opening and closing a circulating tank discharge port in the lower end of the tank body; and therotary spraying guns are arranged at the top end in the tank body, the sand setting inductors used for detecting the height of precipitated drilling cuttings in the circulating tank are arranged on the lower side in the tank body, the fluid supply pump is connected with the rotary spraying guns, and the control module is in electric signal connection with the electronic control valve, the fluid supply pump and the sand setting inductors. The sand setting condition in the tank can be automatically inducted, an alarm prompt is given in time, and the setting quantity can be found in time. Set sand in the tank can be automatically washed away, people do not need to enter the tank again for removal, the removal efficiency is improved, and potential safety hazards are eliminated.
Description
Technical field [0001] The invention belongs to the technical field of drilling engineering circulation system machinery, and specifically relates to an automatic induction cleaning method for a circulation tank and a drilling fluid circulation tank. Background technique [0002] When the drilling fluid circulation tank is filled with drilling fluid, the drilling cuttings in the drilling fluid that have not been removed by the solids control equipment are easy to deposit on the bottom of the circulation tank. Since the amount of sand at the bottom of the tank cannot be detected in time, it is generally only cleaned after drilling. Sand in the tank. As a result, there is a large amount of sand at the bottom of the circulating tank, especially the four corners of the circulating tank, which affects the performance of the drilling fluid during normal drilling; when cleaning the tank, personnel can only clean the sand after entering the circulating tank, which is very labor-intensive...
