Warranty of Large Water Well Drilling Rig
Every product issued shall enjoy a one-year/2000 working hour warranty period, during which we will repair or replace the defective parts free of charge if material or process defects occur and spare parts are in normal working condition.
Drilling Attentions For Water Well
Due to different geological structures in different places, different geological structures are often encountered in the drilling process of drilling machine. In order to achieve good drilling effect, it is necessary to understand the drilling methods of different geological layers
For example, when drilling gypsum layer, the drilling fluid shall be pretested first. Calcium ions can be removed by adding anti gypsum treatment agents such as soda ash calcium removal and viscosity reducer. At the same time, viscosity reducer with strong calcium resistance shall be used to control viscosity cutting, and materials such as fluid loss reducer and anti sloughing agent shall be supplemented to maintain the stability of the performance of the drilling fluid, so as to improve the anti gypsum pollution ability of the drilling fluid in the drilling machine
