Description

TECHNICAL FIELD

[0002] In the prior art, the common ship seawater pump wellbore cleaning method is generally to clean the marine organism shell in the wellbore by using a screw drill. The cleaning method is mainly to rotate the drill bit by a motor to drill the marine organism shell in the wellbore. However, the smaller the outer diameter of the drill bit of the screw drill is, the stronger the drilling force of the screw drill on the sand prevention material is. In order to enhance the drilling force of the screw drill on the sand prevention material, the outer diameter of the drill bit is obviously smaller than the inner diameter of the wellbore. Therefore, only part of the sand prevention material in the wellbore can be removed by the drill bit of the screw drill in one drilling operation. Thus, the position of the drill bit needs to be adjusted for multiple times when the sand prevention material in the wellbore is cleaned by the screw drill. Therefore, the efficiency of cleaning the sand prevention material in the wellbore by the screw drill is relatively low, and the cleaning effect is not ideal. It is necessary to improve the wellbore cleaning device. SUMMARY
