The invention provides an oil, gas and water well shaft cleaning device which comprises a drill bit, a first driving part and a controller. The first driving part is electrically connected with the controller through a cable so as to control the first driving part through the controller to be opened and closed. The output end of the first driving part is fixedly connected with the drill bit so asto drive the drill bit to rotate. According to the oil, gas and water well shaft cleaning device, by arranging the first driving part, the drill bit is fixed to the first driving part, and the controller is electrically connected with the first driving part, so that the controller controls the first driving part to be started, the first driving part drives the drill bit to rotate and performs drilling on dirt on the inner wall of a well shaft, the oil, gas and water well shaft cleaning device can perform drilling to remove a region with the small passable inner diameter or a region with no passable inner diameter inside the well shaft so as to clean the inner wall of the well shaft, and the oil gas production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of oil production engineering in oil fields, in particular to a shaft cleaning device for oil, gas and water wells. Background technique [0002] In the process of oil and gas production, the wellbore is usually used to transport oil, gas or water waiting to be transported. The above-mentioned substances to be transported will adhere to the inner wall of the wellbore to form dirt during the transportation process. These dirt will block the wellbore to a certain extent and affect the normal operation of oil and gas. Production. [0003] In the prior art, a drift gauge is generally used to remove the dirt on the inner wall of the wellbore. Wherein, the gauge includes a fixed rod and a scraper, the outer circumference of the fixed rod is provided with a scraper extending outward, and the scraper is arranged on the fixed rod in a spiral manner. When in use, first fix the first end of the steel wire on the uppe...
