Sep 1, 2022 · Introduction. Geological drilling is a critical link in the discovery, exploration, and exploitation of buried resources, but the existing drilling technology is not yet able to meet the needs of breaking various kinds of rocks and reaching the target layer in terms of economy, safety, efficiency, and environmental protection [1]. The hard rock stratum will seriously affect the efficiency of deep-sea drilling and greatly increase the cost of drilling operations due to its complexity. In ocean drilling operations, the design of the bit is critical. Therefore, the core bit should be able to drill in a variety of formations, especially in hard rock stratum, with the function of reducing the need to change the bit due to ...Aug 23, 2022 · The solar electronic tracking chip sends the coordinate position to the drilling space database system through GPS positioning to realize real-time positioning of drilling geological data and transmit dynamic information of drilling positioning [12–15].
