Mud Injection

 

in mining a means of combating underground fires by delivering mud slurry (a mixture of water with clay or fine-grain sand) to mine workings and worked-out areas. Fires are extinguished with mud through individual wells drilled from the surface, through group wells and a network of underground pipelines, and through underground wells. A distinction is made between preventive mud injection and mud injection for extinguishing fires. In preventive mud injection the mud mix fills hollows and cracks and pre-vents air from getting to the fire-hazard area, thus averting spontaneous combustion of the mineral involved.

The experimental platform of deep-water drilling gas kick detection is mainly composed of a main circulation pipe, mud injection device, natural gas injection and pressure device, cycle pump, and detection device, as shown in Figure 10.
Initial flow testing of the well has returned disappointing results, from which we infer the possibility of formation damage, due to the mud injection, and a limited ability to lift all of the heavy mud from the well bore.
If the mud injection succeeds in overcoming the upward pressure of oil in the well, which stretches 5 kilometres below the sea floor, engineers will proceed with pumping in cement.
