Application of full hydraulic drilling rig in shale formation drilling construction

Abstract:

In the detailed investigation project of talc mine in northwestern Hunan， modular full hydraulic drilling rigs were used for drilling construction， penetrating multiple layers of shale and mudstone formations， and breaking rocks. This paper analyzes various technical problems encountered during the drilling construction process， such as drilling rig capacity， flushing fluid， and borehole annular gap， and proposes countermeasures， which have a certain reference value for the construction of similar mining areas.
