Drilling is a common project in modern times. Although tap water has now spread to the north and south of the Yangtze River, it is not without reason that wells have been sown from ancient times to the present. Drilling can directly cause underground water and can be used for cooking. In the process of drilling, there will also be some unexpected situations, such as drilling drop. Today, Xiao Bian will talk about what to do if drilling drop occurs during drilling.
1.Lower casing of drilling: Make a circular skeleton with steel bars, then fix the wire rope sleeve with small cotton rope, fix the three points on the skeleton with rope, keep the balance under the lower part, and then follow the skeleton and wire rope down the hole together.
2.Detection of drilling: Before I set the drill pipe, I must first admit the depth of the hole where the drill pipe is broken, then check the skew degree of the drill pipe left in the hole through the measuring rope, and admit whether the drill pipe break is attached to the hole wall and the sediment in the hole. The above factors must be recognized, otherwise the skeleton and rope sleeve will be difficult to descend to the predetermined position, and even if the drill pipe is set, it cannot be pulled up due to sediment.
3.Operation and control of drilling: If it is admitted that the drill pipe is attached to the hole wall, install the upper drill bucket with the modified or new drill pipe, lower it to the disconnection place, toggle the drill pipe, make the disconnected drill pipe separate from the hole wall, and then lower the sleeve.
