Tungsten alloy shield for geological well logging is of high density and hardness. It has good radiation shielding ability, which is used to shield the radioactive source. When the solid source is put into the borehole, the radiation can penetrate the rock layer. The data can be used to analyze whether there is oil or gas in the rock.
Geological well drilling is an exploration technique used mainly in the oil and gas industries. It is also known as cable logging and borehole logging. A gamma ray source is lowered into a borehole and the radiation penetrates the rock strata. This data can then be analyzed to determine whether deposits of gas or oil are present.
