City underground engineering drilling

Underground engineering refers to underground civil engineering which is built to develop and utilize underground space resources. It includes underground buildings and underground structures, underground railways, road tunnels, underwater tunnels, underground ditches and street crossings.

Underground construction is the construction of underground buildings and structures, such as tunnels, pipelines, tunnels, oil depot and civil air defense works and so on. Underground buildings have distinct characteristics from those above ground.

Good thermal stability and tightness; With good disaster resistance and protection performance; With good social and environmental benefits; Construction is difficult, construction period is generally longer, one-time investment is higher; People's psychological state should be fully considered when using; Higher requirements for ventilation and drying.

Main application areas:

City underground pipe corridor project, city underground trenchless project, subway, underground tunnel, etc.

Main functions:

The harsh environment of underground drilling operations facilitates the research and development of drilling fluids, which require the ability to perform a number of key tasks during drilling: suspension, pressure control, rock stability, buoyancy, lubrication, and cooling.
