In the mining industry, drilling methods are usually used. Kaiqiu Drilling Tools Co., Ltd. is engaged in drilling work, and we are mainly engaged in drilling hot spring wells. Hot springs are loved by many people, and soaking in hot springs is also a very relaxing health activity. However, natural hot springs are rare, and many hot springs need to be mined. Let us Zhejiang Drilling Company tell you the possible reasons and treatment methods if you encounter obstacles during drilling.
Reasons for drilling resistance during drilling:
The reasons for the resistance when drilling down are: (1) The well collapsed after the trip was completed. (2) The mud performance is not good, the water loss is large, the mud cake is thick, and the formation expansion causes the diameter of the well to shrink. (3) The diameter of the drill bit was severely worn last time, and the new drill bit caused resistance. (4) The mud is not well circulated before the drilling, and the drilling will not go to the bottom. (5) Structural changes of water well drilling tools. If you replace large water well drilling tools or increase the diameter of the centralizer, it is easy to encounter obstacles when you change the type of drill bit.
Treatment method: The mud must be circulated and the performance of the mud must be treated well before the drilling. The mud must be filled in accordance with the regulations during the drilling process, and the hole must be drawn in the process of drilling. Don't force it down. Before drilling, check the size of the drill bit; if the size of the water well drilling tools changes, take care to prevent obstruction and jamming of the drilling.
Through the introduction of Kaiqiu Drilling Tools Co., Ltd., you should know why there is resistance when drilling, and the corresponding handling method is also very clear. When drilling, we will encounter many kinds of problems, and we need to work together to solve them.
