"井孔钻进" can be translated as "wellbore drilling" or "borehole drilling" in English.
Wellbore drilling is a common term in the oil and gas industry, referring to the process of drilling a hole into the earth to create a wellbore for the extraction of hydrocarbons or other resources.
Borehole drilling is a more general term that can be used in various contexts, including geological exploration, water well construction, and environmental monitoring, where a borehole is drilled into the ground for specific purposes.
Both terms are appropriate depending on the context and the specific industry or field in which they are used.
